Information
I. Background
Pursuant to section 189a. (2) of the
Atomic Energy Act of 1954, as amended
(the Act), the U.S. Nuclear Regulatory
Commission (the Commission or NRC
staff) is publishing this notice. The Act
requires the Commission publish notice
of any amendments issued, or proposed
to be issued and grants the Commission
the authority to issue and make
immediately effective any amendment
to an operating license upon a
determination by the Commission that
such amendment involves no significant
hazards consideration, notwithstanding
PO 00000
Frm 00123

the pendency before the Commission of
a request for a hearing from any person.
This notice includes notices of
amendments containing sensitive
unclassified non-safeguards information
(SUNSI).
Notice of Consideration of Issuance of
Amendments to Facility Operating
Licenses, Proposed No Significant
Hazards Consideration Determination,
and Opportunity for a Hearing
The Commission has made a
proposed determination that the
following amendment requests involve
no significant hazards consideration.
Under the Commission’s regulations in
Title 10 of the Code of Federal
Regulations (10 CFR), Section 50.92,
this means that operation of the facility
in accordance with the proposed
amendment would not (1) involve a
significant increase in the probability or
consequences of an accident previously
evaluated; or (2) create the possibility of
a new or different kind of accident from
any accident previously evaluated; or
(3) involve a significant reduction in a
margin of safety. The basis for this
proposed determination for each
amendment request is shown below.
The Commission is seeking public
comments on this proposed
determination. Any comments received
within 30 days after the date of
publication of this notice will be
considered in making any final
determination.
Normally, the Commission will not
issue the amendment until the
expiration of 60 days after the date of
publication of this notice. The
Commission may issue the license
amendment before expiration of the 60day period provided that its final
determination is that the amendment
involves no significant hazards
consideration. In addition, the
Commission may issue the amendment
prior to the expiration of the 30-day
comment period should circumstances
change during the 30-day comment
period such that failure to act in a
timely way would result, for example in
derating or shutdown of the facility.
Should the Commission take action
prior to the expiration of either the
comment period or the notice period, it
will publish in the Federal Register a
notice of issuance. Should the
Commission make a final No Significant
Hazards Consideration Determination,
any hearing will take place after
issuance. The Commission expects that
the need to take this action will occur
very infrequently.
Written comments may be submitted

Rockville, Maryland.
Within 60 days after the date of
publication of this notice, any person(s)
whose interest may be affected by this
action may file a request for a hearing
and a petition to intervene with respect
to issuance of the amendment to the
subject facility operating license.
Requests for a hearing and a petition for
leave to intervene shall be filed in
accordance with the Commission’s
‘‘Rules of Practice for Domestic
Licensing Proceedings’’ in 10 CFR Part
2. Interested person(s) should consult a
current copy of 10 CFR 2.309, which is
available at the Commission’s PDR,
located at One White Flint North, Public
File Area 01F21, 11555 Rockville Pike
(first floor), Rockville, Maryland, or at
https://www.nrc.gov/reading-rm/doccollections/cfr/part002/part0020309.html. Publicly available records
will be accessible from the Agencywide
Documents Access and Management
System’s (ADAMS) Public Electronic
Reading Room on the Internet at the
NRC Web site, https://www.nrc.gov/
reading-rm.html. If a request for a
hearing or petition for leave to intervene
is filed within 60 days, the Commission
or a presiding officer designated by the
Commission or by the Chief
Administrative Judge of the Atomic
Safety and Licensing Board Panel, will
rule on the request and/or petition; and
the Secretary or the Chief
Administrative Judge of the Atomic
Safety and Licensing Board will issue a
notice of a hearing or an appropriate
order.
As required by 10 CFR 2.309, a
petition for leave to intervene shall set
forth with particularity the interest of
the petitioner in the proceeding, and
how that interest may be affected by the
results of the proceeding. The petition
should specifically explain the reasons
why intervention should be permitted
with particular reference to the
following general requirements: (1) The
name, address, and telephone number of
the requestor or petitioner; (2) the
nature of the requestor’s/petitioner’s
right under the Act to be made a party
to the proceeding; (3) the nature and
extent of the requestor’s/petitioner’s
VerDate Nov<24>2008

Jkt 220001
property, financial, or other interest in
the proceeding; and (4) the possible
effect of any decision or order which
may be entered in the proceeding on the
requestor’s/petitioner’s interest. The
petition must also set forth the specific
contentions which the requestor/
petitioner seeks to have litigated at the
proceeding.
Each contention must consist of a
specific statement of the issue of law or
fact to be raised or controverted. In
addition, the requestor/petitioner shall
provide a brief explanation of the bases
for the contention and a concise
statement of the alleged facts or expert
opinion which support the contention
and on which the requestor/petitioner
intends to rely in proving the contention
at the hearing. The requestor/petitioner
must also provide references to those
specific sources and documents of
which the petitioner is aware and on
which the requestor/petitioner intends
to rely to establish those facts or expert
opinion. The petition must include
sufficient information to show that a
genuine dispute exists with the
applicant on a material issue of law or
fact. Contentions shall be limited to
matters within the scope of the
amendment under consideration. The
contention must be one which, if
proven, would entitle the requestor/
petitioner to relief. A requestor/
petitioner who fails to satisfy these
requirements with respect to at least one
contention will not be permitted to
participate as a party.
Those permitted to intervene become
parties to the proceeding, subject to any
limitations in the order granting leave to
intervene, and have the opportunity to
participate fully in the conduct of the
hearing.
If a hearing is requested, and the
Commission has not made a final
determination on the issue of no
significant hazards consideration, the
Commission will make a final
determination on the issue of no
significant hazards consideration. The
final determination will serve to decide
when the hearing is held. If the final
determination is that the amendment
request involves no significant hazards
consideration, the Commission may
issue the amendment and make it
immediately effective, notwithstanding
the request for a hearing. Any hearing
held would take place after issuance of
the amendment. If the final
determination is that the amendment
request involves a significant hazards
consideration, any hearing held would
take place before the issuance of any
amendment.

request for hearing, a petition for leave
to intervene, any motion or other
document filed in the proceeding prior
to the submission of a request for
hearing or petition to intervene, and
documents filed by interested
governmental entities participating
under 10 CFR 2.315(c), must be filed in
accordance with the NRC E-Filing rule
(72 FR 49139, August 28, 2007). The EFiling process requires participants to
submit and serve all adjudicatory
documents over the Internet, or in some
cases to mail copies on electronic
storage media. Participants may not
submit paper copies of their filings
unless they seek an exemption in
accordance with the procedures
described below.
To comply with the procedural
requirements of E-Filing, at least ten
(10) days prior to the filing deadline, the
participant should contact the Office of
the Secretary by e-mail at
hearing.docket@nrc.gov, or by telephone
at (301) 415–1677, to request (1) a
digital ID certificate, which allows the
participant (or its counsel or
representative) to digitally sign
documents and access the E-Submittal
server for any proceeding in which it is
participating; and (2) advise the
Secretary that the participant will be
submitting a request or petition for
hearing (even in instances in which the
participant, or its counsel or
representative, already holds an NRCissued digital ID certificate). Based upon
this information, the Secretary will
establish an electronic docket for the
hearing in this proceeding if the
Secretary has not already established an
electronic docket.
Information about applying for a
digital ID certificate is available on
NRC’s public Web site at https://
www.nrc.gov/site-help/e-submittals/
apply-certificates.html. System
requirements for accessing the ESubmittal server are detailed in NRC’s
‘‘Guidance for Electronic Submission,’’
which is available on the agency’s
public Web site at https://www.nrc.gov/
site-help/e-submittals.html. Participants
may attempt to use other software not
listed on the Web site, but should note
that the NRC’s E-Filing system does not
support unlisted software, and the NRC
Meta System Help Desk will not be able
to offer assistance in using unlisted
software.
If a participant is electronically
submitting a document to the NRC in
accordance with the E-Filing rule, the
participant must file the document
using the NRC’s online, Web-based
submission form. In order to serve
documents through EIE, users will be
required to install a Web browser plug-

information on the Web-based
submission form, including the
installation of the Web browser plug-in,
is available on the NRC’s public Web
site at https://www.nrc.gov/site-help/esubmittals.html.
Once a participant has obtained a
digital ID certificate and a docket has
been created, the participant can then
submit a request for hearing or petition
for leave to intervene. Submissions
should be in Portable Document Format
(PDF) in accordance with NRC guidance
available on the NRC public Web site at
https://www.nrc.gov/site-help/esubmittals.html. A filing is considered
complete at the time the documents are
submitted through the NRC’s E-Filing
system. To be timely, an electronic
filing must be submitted to the E-Filing
system no later than 11:59 p.m. Eastern
Time on the due date. Upon receipt of
a transmission, the E-Filing system
time-stamps the document and sends
the submitter an e-mail notice
confirming receipt of the document. The
E-Filing system also distributes an email notice that provides access to the
document to the NRC Office of the
General Counsel and any others who
have advised the Office of the Secretary
that they wish to participate in the
proceeding, so that the filer need not
serve the documents on those
participants separately. Therefore,
applicants and other participants (or
their counsel or representative) must
apply for and receive a digital ID
certificate before a hearing request/
petition to intervene is filed so that they
can obtain access to the document via
the E-Filing system.
A person filing electronically using
the agency’s adjudicatory E-Filing
system may seek assistance by
contacting the NRC Meta System Help
Desk through the ‘‘Contact Us’’ link
located on the NRC Web site at https://
www.nrc.gov/site-help/esubmittals.html, by e-mail at
MSHD.Resource@nrc.gov, or by a tollfree call at (866) 672–7640. The NRC
Meta System Help Desk is available
between 8 a.m. and 8 p.m., Eastern
Time, Monday through Friday,
excluding government holidays.
Participants who believe that they
have a good cause for not submitting
documents electronically must file an
exemption request, in accordance with
10 CFR 2.302(g), with their initial paper
filing requesting authorization to
continue to submit documents in paper
format. Such filings must be submitted
by: (1) First class mail addressed to the
Office of the Secretary of the
Commission, U.S. Nuclear Regulatory

Sixteenth Floor, One White Flint North,
11555 Rockville Pike, Rockville,
Maryland 20852, Attention: Rulemaking
and Adjudications Staff. Participants
filing a document in this manner are
responsible for serving the document on
all other participants. Filing is
considered complete by first-class mail
as of the time of deposit in the mail, or
by courier, express mail, or expedited
delivery service upon depositing the
document with the provider of the
service. A presiding officer, having
granted an exemption request from
using E-Filing, may require a participant
or party to use E-Filing if the presiding
officer subsequently determines that the
reason for granting the exemption from
use of E-Filing no longer exists.
Documents submitted in adjudicatory
proceedings will appear in NRC’s
electronic hearing docket which is
available to the public at https://
ehd.nrc.gov/EHD_Proceeding/home.asp,
unless excluded pursuant to an order of
the Commission, or the presiding
officer. Participants are requested not to
include personal privacy information,
such as social security numbers, home
addresses, or home phone numbers in
their filings, unless an NRC regulation
or other law requires submission of such
information. With respect to
copyrighted works, except for limited
excerpts that serve the purpose of the
adjudicatory filings and would
constitute a Fair Use application,
participants are requested not to include
copyrighted materials in their
submission.
Petitions for leave to intervene must
be filed no later than 60 days from
January 5, 2010. Non-timely filings will
not be entertained absent a
determination by the presiding officer
that the petition or request should be
granted or the contentions should be
admitted, based on a balancing of the
factors specified in 10 CFR
2.309(c)(1)(i)–(viii).

Carolina Power & Light Company,
Docket No. 50–261, H. B. Robinson
Steam Electric Plant (HBRSEP) Unit No.
2, Darlington County, South Carolina
Date of amendment request: June 19,
2009, as supplemented by letter dated
October 20, 2009.
Description of amendment request:
This amendment request contains
sensitive unclassified non-safeguards
information (SUNSI). The proposed
amendment would revise TS 3.3.1,
‘‘Reactor Protection System
Instrumentation.’’ The proposed change
revises the requirements related to the
reactor protection system interlock for
the turbine trip input to the reactor
protection system.
Basis for proposed no significant
hazards consideration determination:
As required by 10 CFR 50.91(a), the
licensee has provided its analysis of the
issue of no significant hazards
consideration, which is presented
below:
1. The Proposed Change Does Not Involve
a Significant Increase in the Probability or
Consequences of an Accident Previously
Evaluated.
The proposed change provides revised
requirements for the reactor protection
system interlock associated with the turbine
trip protection function. The proposed
change will allow the interlock for turbine
trip function to be raised from the current
interlock setting of nominally 10 percent
reactor power to nominally 40 percent
reactor power.
This change will allow the reactor to
continue operating safely at power levels up
to nominally 40 percent when the turbine is
not operating. The applicable accident
analyses, as described in the HBRSEP, Unit
No. 2, Updated Final Safety Analysis Report
(UFSAR) have been reviewed. The turbine
trip input to reactor trip has been verified to
be either not used in the accident analyses
or that the change does not adversely affect
the analyses results and conclusion.
Therefore, it is concluded that the
consequences as described in the UFSAR
accident analyses are unaffected by the
proposed change.
An analysis of plant response to a turbine
trip at nominally 40 percent power provided
with the amendment request shows that the
applicable acceptance criteria are met.
Specifically, analysis has shown that a
turbine trip without a reactor trip below 40
percent power does not challenge the
pressurizer PORVs [power operated relief
valves] or the steam generator safety valves;
thereby, not adversely affecting the
probability of a small break LOCA [loss of
coolant accident] due to a stuck open PORV,
or an excessive cooldown event due to a
stuck open steam generator safety valve. As
a result, the probability of any accident

05JAN1
srobinson on DSKHWCL6B1PROD with PROPOSALS
Federal Register / Vol. 75, No. 2 / Tuesday, January 5, 2010 / Notices
previously evaluated is not significantly
increased by the proposed changes.
Therefore, operation of the facility in
accordance with the proposed amendment
does not involve a significant increase in the
probability or consequences of an accident
previously evaluated.
2. The Proposed Change Does Not Create
the Possibility of a New or Different Kind of
Accident From Any Previously Evaluated.
As described above, the proposed change
provides revised requirements for the reactor
protection system interlock associated with
the turbine trip protection function. The
proposed change will allow the interlock for
turbine trip function to be raised from the
current interlock setting of nominally 10
percent reactor power to nominally 40
percent reactor power.
No new accident initiators or precursors
are introduced by the proposed change.
Changing the interlock for the reactor trip on
turbine trip from P–7 to P–8 changes the
power level associated with enabling and
disabling the reactor trip on turbine trip
function. The turbine pressure input to the
reactor protection system permissive is not
an accident initiator. The change does not
affect how the associated trip functional
units operate or function. The changes do not
create the possibility of a new or different
kind of accident from any previously
evaluated because these interlock changes do
not affect the way that the associated trip
functional units operate or function.
Therefore, operation of the facility in
accordance with the proposed amendment
would not create the possibility of a new or
different kind of accident from any
previously evaluated.
3. The Proposed Change Does Not Involve
a Significant Reduction in the Margin of
Safety.
As described above, the proposed change
provides revised requirements for the reactor
protection system interlock associated with
the turbine trip protection function. The
proposed change will allow the interlock for
the turbine trip function to be raised from the
current interlock setting of nominally 10
percent reactor power to nominally 40
percent reactor power.
Also, as previously described, this change
will allow the reactor to continue operating
safely at power levels up to nominally 40
percent when the turbine is not operating.
The applicable UFSAR accident analyses
have been reviewed and it is concluded that
the accident analyses are unaffected by the
proposed change. An analysis of plant
response to a turbine trip at nominally 40
percent power shows that the applicable
acceptance criteria are met. Based on these
evaluations, the margins of safety that could
potentially have been impacted by the
proposed change associated with the reactor,
which include departure from nucleate
boiling (DNB) and fuel temperature margins,
and the margin of safety associated with
reactor coolant system integrity, are not
affected.
Therefore, operation of the facility in
accordance with the proposed amendment
would not involve a significant reduction in
the margin of safety.

Docket No. 50–271, Vermont Yankee
Nuclear Power Station, Vernon,
Vermont
Date of amendment request: October
27, 2009.
Description of amendment request:
This amendment request contains
sensitive unclassified non-safeguards
information (SUNSI). This amendment
request would change the Technical
Specifications to provide revised values
for the Safety Limit Minimum Critical
Power Ratio (SLMCPR) for both single
and dual recirculation loop operation.
Basis for proposed no significant
hazards consideration determination:
As required by 10 CFR 50.91(a), the
licensee has provided its analysis of the
issue of no significant hazards
consideration, which is presented
below:
1. The operation of Vermont Yankee
Nuclear Power Station in accordance with
the proposed amendment will not involve a
significant increase in the probability or
consequences of an accident previously
evaluated.
The basis of the Safety Limit MCPR
(SLMCPR) is to ensure no mechanistic fuel
damage is calculated to occur if the limit is
not violated. The new SLMCPR values
preserve the existing margin to transition
boiling and probability of fuel damage is not
increased. The derivation of the revised
SLMCPR for Vermont Yankee for
incorporation into the Technical
Specifications and its use to determine plant
and cycle-specific thermal limits has been
performed using NRC approved methods.
These plant-specific calculations are
performed each operating cycle and if
necessary, will require future changes to
these values based upon revised core designs.
The revised SLMCPR values do not change
the method of operating the plant and have
no effect on the probability of an accident
initiating event or transient.
Based on the above, Vermont Yankee has
concluded that the proposed change will not
result in a significant increase in the
probability or consequences of an accident
previously evaluated.
2. The operation of Vermont Yankee
Nuclear Power Station in accordance with
the proposed amendment will not create the
PO 00000
Frm 00126
Fmt 4703
Sfmt 4703
461
possibility of a new or different kind of
accident from any accident previously
evaluated.
The proposed changes result only from a
specific analysis for the Vermont Yankee core
reload design. These changes do not involve
any new or different methods for operating
the facility. No new initiating events or
transients result from these changes.
Based on the above, Vermont Yankee has
concluded that the proposed change will not
create the possibility of a new or different
kind of accident from those previously
evaluated.
3. The operation of Vermont Yankee
Nuclear Power Station in accordance with
the proposed amendment will not involve a
significant reduction in a margin of safety.
The new SLMCPR is calculated using NRC
approved methods with plant and cycle
specific parameters for the current core
design. The SLMCPR value remains
conservative enough to ensure that greater
than 99.9% of all fuel rods in the core will
avoid transition boiling if the limit is not
violated, thereby preserving the fuel cladding
integrity. The operating MCPR limit is set
appropriately above the safety limit value to
ensure adequate margin when the cycle
specific transients are evaluated.
Accordingly, the margin of safety is
maintained with the revised values.
As a result, Vermont Yankee has
determined that the proposed change will not
result in a significant reduction in the margin
of safety.
The NRC staff has reviewed the
licensee’s analysis and, based on this
review, it appears that the three
standards of 10 CFR 50.92(c) are

Basis for proposed no significant
hazards consideration determination:
As required by 10 CFR 50.91(a), the
licensee has provided its analysis of the
issue of no significant hazards
consideration, which is presented
below:
1. Does the proposed change involve a
significant increase in the probability or
consequences of an accident previously
evaluated?
Response: No.
The Minimum Critical Power Ratio (MCPR)
limit is defined in the Bases to Technical
Specification 2.1.1.2 as that limit, ‘‘that, in
the event of an AOO [(Anticipated
Operational Occurrence)] from the limiting
condition of operation, at least 99.9% of the
fuel rods in the core would be expected to
avoid boiling transition.’’ The MCPR safety
limit satisfies the requirements of General
Design Criterion 10 of Appendix A to
10CFR50 regarding acceptable fuel design
limits. The MCPR safety limit is reevaluated
for each reload using NRC-approved
methodologies. The analyses for GGNS
[Grand Gulf Nuclear Station] Cycle 18 have
concluded that a two-loop MCPR safety limit
of 1.09, based on the application of Global
Nuclear Fuels’ NRC approved MCPR safety
limit methodology, will ensure that this
acceptance criterion is met. For single-loop
operation, a MCPR safety limit of 1.12, also
ensures that this acceptance criterion is met.
The MCPR operating limits are presented and
controlled in accordance with the GGNS Core
Operating Limits Report (COLR).
The requested Technical Specification
changes do not involve any plant
modifications or operational changes that
could affect system reliability or performance
or that could affect the probability of operator
error. The requested changes do not affect
any postulated accident precursors, do not
affect any accident mitigating systems, and
do not introduce any new accident initiation
mechanisms.
Therefore, the changes to the Minimum
Critical Power Ratio safety limit do not
involve a significant increase in the
probability or consequences of any accident
previously evaluated.
2. Does the proposed change create the
possibility of a new or different kind of
accident from any accident previously
evaluated?
Response: No.
The GNF2 fuel to be used in Cycle 18 is
of a design compatible with the co-resident
GE14 and ATRIUM–10 fuel. Therefore, the
introduction of GNF2 fuel into the Cycle 18
core will not create the possibility of a new
or different kind of accident. The proposed
changes do not involve any new modes of
operation, any changes to setpoints, or any
plant modifications. The proposed revised
MCPR safety limits have accounted for the
mixed fuel core and have been shown to be
acceptable for Cycle 18 operation.
Compliance with the criterion for incipient
boiling transition continues to be ensured.
The core operating limits will continue to be
developed using NRC approved methods
which also account for the mixed fuel core
design. The proposed MCPR safety limits or
VerDate Nov<24>2008

Jkt 220001
methods for establishing the core operating
limits do not result in the creation of any
new precursors to an accident.
Therefore, this change does not create the
possibility of a new or different kind of
accident from any previously evaluated.
3. Does the proposed change involve a
significant reduction in a margin of safety?
Response: No.
The MCPR safety limits have been
evaluated in accordance with Global Nuclear
Fuels NRC-approved cycle-specific safety
limit methodology to ensure that during
normal operation and during AOO’s at least
99.9% of the fuel rods in the core are not
expected to experience transition boiling.
The proposed revised MCPR safety limits
have accounted for the mixed fuel core and
have been shown to be acceptable for Cycle
18 operation. Compliance with the criterion
for incipient boiling transition continues to
be ensured. On this basis, the
implementation of the change to the MCPR
safety limits does not involve a significant
reduction in a margin of safety.
Therefore, the proposed change does not
involve a significant reduction in a margin of
safety.
The NRC staff has reviewed the
licensee’s analysis and, based on this
review, it appears that the three
standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff
proposes to determine that the
amendment request involves no
significant hazards consideration.

As required by 10 CFR 50.91(a), the
licensee has provided its analysis of the
issue of no significant hazards
consideration, which is presented
below:
PO 00000
Frm 00127
Fmt 4703
Sfmt 4703
1. Does the proposed amendment involve
a significant increase in the probability or
consequences of an accident previously
evaluated?
Response: No.
The probability (frequency of occurrence)
of design basis accidents (DBAs) occurring is
not affected by the NUMAC PRNM System,
since the system does not interact with
equipment whose failure could cause an
accident. Compliance with the regulatory
criteria established for plant equipment are
maintained with the installation of the
upgraded NUMAC PRNM System. Scram
setpoints in the NUMAC PRNM System are
established such that the analytical limits are
met.
The unavailability of the new NUMAC
PRNM System is equal to or less than the
existing system and, as a result, the scram
reliability is equal to or better than the
existing analog power system. No new
challenges to safety-related equipment result
from the NUMAC PRNM System
modification. Therefore, the proposed change
does not involve a significant increase in the
probability of an accident previously
evaluated.
The proposed change replaces the current
Option E–I–A stability solution with an NRCapproved Option III long-term stability
solution. The NUMAC PRNM hardware
incorporates the Oscillation Power Range
Monitor (OPRM) Option III detect-andsuppress solution, which has been previously
reviewed and approved by the NRC. The
OPRM meets [10 CFR Part 50, Appendix A]
General Design Criterion (GDC) 10, Reactor
Design, and GDC 12, Suppression of Reactor
Power Oscillations, requirements by
automatically detecting and suppressing
design basis thermal-hydraulic oscillations
prior to exceeding the fuel Minimum Critical
Power Ratio (MCPR) Safety Limit.
Based on the above, installation of the new
NUMAC PRNM System with the OPRM
Option III stability solution integrated into
the NUMAC PRNM equipment does not
increase the probability or consequences of
an accident previously evaluated.
2. Does the proposed amendment create
the possibility of a new or different kind of
accident from any accident previously
evaluated?
Response: No.
The components of the NUMAC PRNM
System are equivalent or of better design and
qualification criteria than those currently
installed and utilized in the plant. No new
operating mode, safety-related equipment
lineup, accident scenario, or interaction
mode not reviewed and approved as part of
the design and licensing of the NUMAC
PRNM System has been identified. Therefore,
the NUMAC PRNM System retrofit does not
adversely affect plant equipment.
The new NUMAC PRNM System uses
digital equipment that has softwarecontrolled digital processing compared to the
existing power range system that uses mostly
analog and discrete component processing.
Specific failures of hardware and potential
software common-cause failures are different
from the existing system. The effects of
potential software common-cause failure are
mitigated by specific hardware design and
E:\FR\FM\05JAN1.SGM
05JAN1
Federal Register / Vol. 75, No. 2 / Tuesday, January 5, 2010 / Notices
system architecture as discussed in Section
6.0 of [GE Nuclear Energy Licensing Topical
Report] NEDC–32410P–A. Failure(s) of the
system have the same overall effect as the
present design. No new or different kinds of
accidents are introduced. Therefore, the
NUMAC PRNM System does not adversely
effect plant equipment.
The currently installed Average Power
Range Monitoring (APRM) system is replaced
with a NUMAC PRNM System that performs
the existing power range monitoring
functions and adds an OPRM to react
automatically to potential reactor thermalhydraulic instabilities.
Based on the above, the proposed change
does not create the possibility of a new or
different kind of accident from any accident
previously evaluated.
3. Does the proposed amendment involve
a significant reduction in a margin of safety?
Response: No.
The proposed TS changes associated with
the NUMAC PRNM System retrofit
implement the constraints of the NUMAC
PRNM System design and related stability
analyses. The NUMAC PRNM System change
does not impact reactor operating parameters
or the functional requirements of the APRM
system. The replacement equipment
continues to provide information, enforce
control rod blocks, and initiate reactor
scrams under appropriate specified
conditions. The proposed change does not
reduce safety margins. The replacement
APRM equipment has improved channel trip
accuracy compared to the current analog
system, and meets or exceeds system
requirements previously assumed in setpoint
analysis. Thus, the ability of the new
equipment to enforce compliance with
margins of safety equals or exceeds the
ability of the equipment which it replaces.
Therefore, the proposed changes do not
involve a reduction in a margin of safety.

Description of amendment request:
This amendment request contains
sensitive unclassified non-safeguards
information (SUNSI). The amendment(s)
would revise Technical Specification
(TS) 4.3.1, ‘‘Criticality,’’ to address a
VerDate Nov<24>2008

non-conservative TS. The proposed
change addresses the Boraflex
degradation issue in the LaSalle County
Station (LSCS) Unit 2 spent fuel storage
racks by revising TS Section 4.3.1 to
allow the use of NETCO–SNAP–IN®
rack inserts in LSCS Unit 2 spent fuel
storage rack cells as a replacement for
the neutron absorbing properties of the
existing Boraflex panels.
Basis for proposed no significant
hazards consideration determination:
As required by 10 CFR 50.91(a), the
licensee has provided its analysis of the
issue of no significant hazards
consideration, which is presented
below:
1. Does the proposed change involve a
significant increase in the probability or
consequences of an accident previously
evaluated?
Response: No.
The proposed change adds an additional
requirement to TS Section 4.3.1 to install a
NETCO–SNAP–IN® rack insert in spent fuel
storage rack cells that cannot otherwise
maintain the requirements of TS Section
4.3.1.1.a to ensure that the effective neutron
multiplication factor, Keff, is less than or
equal to 0.95, if the spent fuel pool (SFP) is
fully flooded with unborated water. The
proposed change also includes a revision to
TS Section 4.3.1 to specify the bounding
reactivity fuel design allowed for storage in
the Unit 1 and Unit 2 SFPs. Since the
proposed change pertains only to the SFP,
only those accidents that are related to
movement and storage of fuel assemblies in
the SFP could be potentially affected by the
proposed change.
The current licensing basis for the LSCS
Unit 2 SFP credits the neutron absorbing
properties of the Boraflex neutron poison
material in the spent fuel storage racks. The
current licensing basis demonstrates: (1)
Adequate margin to criticality for spent fuel
storage rack cells that credit the neutron
absorption capabilities of Boraflex, (2)
adequate margin for fuel assemblies
inadvertently placed into locations adjacent
to the spent fuel storage racks, and (3)
adequate margin for assemblies accidentally
dropped onto the spent fuel storage racks.
Therefore, the probability that a misplaced
fuel assembly would result in an inadvertent
criticality is unchanged since the process and
procedural controls governing fuel movement
in the SFP will not be changed. The dose
consequences of the most limiting drop of a
fuel assembly in the SFP is limited by the
number of the fuel rods damaged and other
engineered features unaffected by the
proposed change, including the fuel design,
fuel decay time, water level in the SFP, water
temperature of the SFP, and the engineering
features of the Reactor Building Ventilation
System.
The installation of NETCO–SNAP–IN®
rack inserts does not result in a significant
increase in the probability of an accident
previously analyzed. The revised criticality
analysis takes no credit for the Boraflex
material. The use of a rack insert provides an
alternative neutron absorber to take the place
PO 00000
Frm 00128
Fmt 4703
Sfmt 4703
463
of the degraded Boraflex material, without
removal of the existing Boraflex. The
probability that a fuel assembly would be
dropped is unchanged by the installation of
the NETCO–SNAP–IN® rack inserts. These
events involve failures of administrative
controls, human performance, and
equipment failures that are unaffected by the
presence or absence of Boraflex and the rack
inserts.
The installation of NETCO–SNAP–IN®
rack inserts does not result in a significant
increase in the consequence of an accident
previously analyzed. A criticality analysis
has been prepared to demonstrate adequate
margin to criticality for spent fuel storage
rack cells with rack inserts in the LSCS Unit
2 SFP, and adequate criticality margin for
assemblies accidentally dropped onto the
spent fuel storage racks.
The installation of NETCO–SNAP–IN@
rack inserts does not affect the consequences
of a dropped fuel assembly. The
consequences of dropping a fuel assembly
onto any other fuel assembly or other
structure are unaffected by the change. The
consequences of dropping a fuel assembly
onto a spent fuel storage rack cell with a rack
insert are bounded by the event of dropping
an assembly onto another assembly, both for
criticality and for radiological consequences.
For criticality, the effects on Keff of dropping
a fuel assembly have been evaluated and are
acceptable. For radiological consequences,
the number of rods damaged when a fuel
assembly is accidentally dropped onto a
spent fuel storage rack cell with or without
a rack insert is bounded by the number of
rods damaged by an assembly dropped onto
another assembly. The change does not affect
the effectiveness of the other engineered
design features to limit the offsite dose
consequences of the limiting fuel assembly
drop accident.
Therefore, the proposed change does not
involve a significant increase in the
probability or consequences of an accident
previously evaluated.
2. Does the proposed change create the
possibility of a new or different kind of
accident from any accident previously
evaluated?
Response: No.
Onsite storage of spent fuel assemblies in
the SFP is a normal activity for which LSCS
has been designed and licensed. As part of
assuring that this normal activity can be
performed without endangering public health
and safety, the ability to safely accommodate
different possible accidents in the SFP, such
as dropping a fuel assembly or misloading a
fuel assembly, have been analyzed. The
proposed spent fuel storage configuration
does not change the methods of fuel
movement or spent fuel storage. The
proposed change allows for continued use of
spent fuel storage rack cells that have been
determined unusable based on the
degradation of Boraflex within those spent
fuel storage rack cells. The rack inserts are
passive devices. These devices, when inside
a spent fuel storage rack cell, perform the
same function as the Boraflex in that cell
without the potential for degradation. These
devices do not add any limiting structural
loads or affect the removal of decay heat from

the assemblies. No change in total heat load
in the SFP is being made. The devices are
resistant to corrosion and will maintain their
structural integrity over the life of the SFP.
An accidental fuel assembly drop does not
challenge their structural integrity. The
existing fuel handling accident, which
assumes the drop of a fuel assembly, bounds
the drop of a rack insert and/or rack insert
installation tool. This change does not create
the possibility of a misloaded assembly into
a spent fuel storage rack cell.
The misloading of a more reactive
assembly targeted for placement in the LSCS
Unit 1 SFP or the LSCS Unit 2 SFP Boraflex
region in a rack insert region of the LSCS
Unit 2 SFP has been prevented since the
most reactive fuel assembly at LSCS is
bounded by the rack insert criticality
analysis, and the most reactive fuel assembly
allowed for future insertion in either the Unit
1 or Unit 2 SFP is being limited to the
reference bounding ATRIUM–10 fuel
assembly.
Therefore, the proposed change does not
create the possibility of a new or different
kind of accident from any accident
previously evaluated.
3. Does the proposed change involve a
significant reduction in a margin of safety?
Response: No.
LSCS TS 4.3.1.1 requires the spent fuel
storage racks to maintain the effective
neutron multiplication factor, Keff, less than
or equal to 0.95 when fully flooded with
unborated water, which includes an
allowance for uncertainties. Therefore, for
criticality, the required safety margin is 5%
including a conservative margin to account
for engineering and manufacturing
uncertainties.
The proposed change provides an
alternative method to ensure that Keff
continues to be less than or equal to 0.95,
thus preserving the required safety margin of
5%. The criticality analysis demonstrates the
required margin to criticality of 5%,
including a conservative margin to account
for engineering and manufacturing
uncertainties, is maintained assuming an
infinite array of fuel with all fuel at the peak
reactivity. In addition, the margin of safety
for radiological consequences of a dropped
fuel assembly are unchanged because the
event involving a dropped fuel assembly onto
a spent fuel storage rack cell containing a fuel
assembly with a rack insert is bounded by the
consequences of a dropped fuel assembly
without a rack insert. The proposed change
also maintains the capacity of the Unit 2 SFP
to be no more than 4078 fuel assemblies.
Therefore, the proposed change does not
involve a significant reduction in a margin of
safety.
The NRC staff has reviewed the
licensee’s analysis and, based on this
review, it appears that the three
standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff
proposes to determine that the
amendment request involves no

No. 1, Salem County, New Jersey
Date of amendment request: October
8, 2009.
Description of amendment request:
This amendment request contains
sensitive unclassified non-safeguards
information (SUNSI). The proposed
amendment would revise Technical
Specification (TS) 6.8.4.i, ‘‘Steam
Generator (SG) Program,’’ by adding a
one-time alternate repair criterion that
excludes certain portions of the tube
below the top of the SG tubesheet from
periodic SG tube inspections. In
addition, the proposed amendment
would revise TS 6.9.10, ‘‘Steam
Generator Tube Inspection Report,’’ to
provide reporting requirements specific
to the alternate repair criteria. The
proposed amendment is supported by
Westinghouse Electric Company, LLC
Topical Report WCAP–17071–P, ‘‘H*:
Alternate Repair Criteria for the
Tubesheet Expansion Region in Steam
Generators with Hydraulically
Expanded Tubes (Model F).’’ H*
(pronounced ‘‘H star’’) is the length of
hydraulically expanded SG tube that
must remain intact within the tubesheet
in order for the joint to resist pullout
and leakage due to normal operating
and accident conditions.
Basis for proposed no significant
hazards consideration determination:
As required by 10 CFR 50.91(a), the
licensee has provided its analysis of the
issue of no significant hazards
consideration, which is presented
below:
1. The proposed changes do not involve a
significant increase in the probability or
consequences of an accident previously
evaluated.
The previously analyzed accidents are
initiated by the failure of plant structures,
systems, or components. The proposed
change that alters the steam generator (SG)
inspection and reporting criteria does not
have a detrimental impact on the integrity of
any plant structure, system, or component
that initiates an analyzed event. The
proposed change will not alter the operation
of, or otherwise increase the failure
probability of any plant equipment that
initiates an analyzed accident.
Of the applicable accidents previously
evaluated, the limiting transients with
consideration to the proposed change to the
SG tube inspection and repair criteria are the
steam generator tube rupture (SGTR) event,
the steam line break (SLB), and the feed line
break (FLB) postulated accidents.
During the SGTR event, the required
structural integrity margins of the SG tubes
PO 00000
Frm 00129
Fmt 4703

and the tube-to-tubesheet joint over the H*
distance will be maintained. Tube rupture in
tubes with cracks within the tubesheet is
precluded by the constraint provided by the
presence of the tubesheet and the tube-totubesheet joint. Tube burst cannot occur
within the thickness of the tubesheet. The
tube-to-tubesheet joint constraint results from
the hydraulic expansion process, thermal
expansion mismatch between the tube and
tubesheet, and from the differential pressure
between the primary and secondary side, and
tubesheet rotation. Based on this design, the
structural margins against burst, as discussed
in Regulatory Guide (RG) 1.121, ‘‘Bases for
Plugging Degraded PWR [pressurized-water
reactor] Steam Generator Tubes,’’ and
Technical Specification 6.8.4.i, are
maintained for both normal and postulated
accident conditions.
The proposed change has no impact on the
structural or leakage integrity of the portion
of the tube outside of the tubesheet. The
proposed change maintains structural and
leakage integrity of the SG tubes consistent
with the performance criteria of Technical
Specification 6.8.4.i. Therefore, the proposed
change results in no significant increase in
the probability of the occurrence of a SGTR
accident.
At normal operating pressures, leakage
from tube degradation below the proposed
limited inspection depth is limited by the
tube-to-tubesheet crevice. Consequently,
negligible normal operating leakage is
expected from degradation below the
inspected depth within the tubesheet region.
The consequences of an SGTR event are not
affected by the primary-to-secondary leakage
flow during the event as primary-tosecondary leakage flow through a postulated
tube that has been pulled out of the tubesheet
is essentially equivalent to a severed tube.
Therefore, the proposed change does not
result in a significant increase in the
consequences of a SGTR[.]
The probability of a SLB is unaffected by
the potential failure of a steam generator tube
as the failure of tube is not an initiator for
a SLB event.
The leakage factor of 2.16 for Salem Unit
1, for a postulated SLB/FLB, has been
calculated as shown in Table 9–7 of WCAP–
17071–P as revised by the response to RAI
[request for additional information] 24
(Attachment 7 [to the application dated
October 8, 2009]). Through application of the
limited tubesheet inspection scope, the
existing operating leakage limit provides
assurance that excessive leakage (i.e., greater
than accident analysis assumptions) will not
occur. The accident analysis calculations
have an assumption of 0.6 [gallons per
minute (gpm)] at room temperature (gpmRT)
primary-to-secondary leakage in a single SG
and 1 gpm at room temperature (gpmRT)
total primary-to-secondary leakage for all
SGs. This apportioned primary-to-secondary
leakage is used in the Main Steam Line Break
and Locked Rotor accidents. Primary-tosecondary leakage of 1 gpm at room
temperature (gpmRT) in a single SG is used
in the Control Rod Ejection (CRE) accident.
No leakage factor will be applied to the
locked rotor or control rod ejection transients
due to their short duration.

srobinson on DSKHWCL6B1PROD with PROPOSALS
The TS operational leak rate limit is 150
gallons per day (gpd) (0.104 gpmRT). The
maximum accident leak rate ratio for Salem
Unit 1 is 2.16. Consequently, this results in
significant margin between the
conservatively estimated accident leakage
and the allowable accident leakage.
For the condition monitoring (CM)
assessment, the component of leakage from
the prior cycle from below the H* distance
will be multiplied by a factor of 2.16 and
added to the total leakage from any other
source and compared to the allowable
accident induced leakage limit. For the
operational assessment (OA), the difference
in the leakage between the allowable leakage
and the accident induced leakage from
sources other than the tubesheet expansion
region will be divided by 2.16 and compared
to the observed operational leakage.
Based on the above, the proposed change
does not involve a significant increase in the
probability or consequences of an accident
previously evaluated.
2. The proposed changes do not create the
possibility of a new or different kind of
accident from any previously evaluated.
The proposed change that alters the steam
generator inspection and reporting criteria
does not introduce any new equipment,
create new failure modes for existing
equipment, or create any new limiting single
failures. Plant operation will not be altered,
and all safety functions will continue to
perform as previously assumed in accident
analyses. Therefore, the proposed change
does not create the possibility of a new or
different kind of accident from any
previously evaluated.
3. The proposed changes do not involve a
significant reduction in the margin of safety.
The proposed change defines the safety
significant portion of the tube that must be
inspected and repaired (plugged). WCAP–
17071–P identifies the specific inspection
depth below which any type tube
degradation shown to have no impact on the
performance criteria in [Nuclear Energy
Institute (NEI) document] NEI 97–06
[Revision] 2, ‘‘Steam Generator Program
Guidelines.’’
The proposed change that alters the steam
generator inspection and reporting criteria
maintains the required structural margins of
the SG tubes for both normal and accident
conditions. Nuclear Energy Institute 97–06,
‘‘Steam Generator Program Guidelines,’’ and
NRC Regulatory Guide (RG) 1.121, ‘‘Bases for
Plugging Degraded PWR Steam Generator
Tubes,’’ are used as the bases in the
development of the limited hot leg tubesheet
inspection depth methodology for
determining that SG tube integrity
considerations are maintained within
VerDate Nov<24>2008

Jkt 220001
acceptable limits. RG 1.121 describes a
method acceptable to the NRC for meeting
General Design Criteria (GDC) 14, ‘‘Reactor
Coolant Pressure Boundary,’’ GDC 15,
‘‘Reactor Coolant System Design,’’ GDC 31,
‘‘Fracture Prevention of Reactor Coolant
Pressure Boundary,’’ and GDC 32,
‘‘Inspection of Reactor Coolant Pressure
Boundary,’’ by reducing the probability and
consequences of a SGTR. RG 1.121 concludes
that by determining the limiting safe
conditions for tube wall degradation, the
probability and consequences of a SGTR are
reduced. This RG uses safety factors on loads
for tube burst that are consistent with the
requirements of Section III of the American
Society of Mechanical Engineers (ASME)
Code.
For axially oriented cracking located
within the tubesheet, tube burst is precluded
due to the presence of the tubesheet. For
circumferentially oriented cracking,
Westinghouse WCAP–17071–P defines a
length of degradation-free expanded tubing
that provides the necessary resistance to tube
pullout due to the pressure induced forces,
with applicable safety factors applied.
Application of the limited hot and cold leg
tubesheet inspection criteria will preclude
unacceptable primary-to-secondary leakage
during all plant conditions. The methodology
for determining leakage as described in
WCAP–1707[1]–P shows that significant
margin exists between an acceptable level of
leakage during normal operating conditions
that ensures meeting the accident-induced
leakage assumptions and the TS leakage limit
of 150 gpd.
The NRC staff has reviewed the
licensee’s analysis and, based on this
review, it appears that the three
standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff
proposes to determine that the
amendment request involves no
significant hazards consideration.

A. This Order contains instructions
regarding how potential parties to this
proceeding may request access to
documents containing Sensitive
Unclassified Non-Safeguards
Information (SUNSI).
B. Within 10 days after publication of
this notice of hearing and opportunity to
petition for leave to intervene, any
potential party who believes access to
SUNSI is necessary to respond to this
notice may request such access. A
‘‘potential party’’ is any person who
intends to participate as a party by
demonstrating standing and filing an
admissible contention under 10 CFR
2.309. Requests for access to SUNSI
submitted later than 10 days after
publication will not be considered
absent a showing of good cause for the
late filing, addressing why the request
could not have been filed earlier.

Federal Register / Vol. 75, No. 2 / Tuesday, January 5, 2010 / Notices
C. The requestor shall submit a letter
requesting permission to access SUNSI
to the Office of the Secretary, U.S.
Nuclear Regulatory Commission,
Washington, DC 20555–0001, Attention:
Rulemakings and Adjudications Staff,
and provide a copy to the Associate
General Counsel for Hearings,
Enforcement and Administration, Office
of the General Counsel, Washington, DC
20555–0001. The expedited delivery or
courier mail address for both offices is:
U.S. Nuclear Regulatory Commission,
11555 Rockville Pike, Rockville,
Maryland 20852. The e-mail address for
the Office of the Secretary and the
Office of the General Counsel are
Hearing.Docket@nrc.gov and
OGCmailcenter@nrc.gov, respectively.1
The request must include the following
information:
(1) A description of the licensing
action with a citation to this Federal
Register notice;
(2) The name and address of the
potential party and a description of the
potential party’s particularized interest
that could be harmed by the action
identified in C.(1);
(3) The identity of the individual or
entity requesting access to SUNSI and
the requestor’s basis for the need for the
information in order to meaningfully
participate in this adjudicatory
proceeding. In particular, the request
must explain why publicly available
versions of the information requested
would not be sufficient to provide the
basis and specificity for a proffered
contention;
D. Based on an evaluation of the
information submitted under paragraph
C.(3) the NRC staff will determine
within 10 days of receipt of the request
whether:
(1) There is a reasonable basis to
believe the petitioner is likely to
establish standing to participate in this
NRC proceeding; and
(2) The requestor has established a
legitimate need for access to SUNSI.
E. If the NRC staff determines that the
requestor satisfies both D.(1) and D.(2)
above, the NRC staff will notify the
requestor in writing that access to
SUNSI has been granted. The written
notification will contain instructions on
how the requestor may obtain copies of
the requested documents, and any other
conditions that may apply to access to
those documents. These conditions may
include, but are not limited to, the
signing of a Non-Disclosure Agreement
or Affidavit, or Protective Order 2 setting
forth terms and conditions to prevent
the unauthorized or inadvertent
disclosure of SUNSI by each individual
who will be granted access to SUNSI.
F. Filing of Contentions. Any
contentions in these proceedings that
are based upon the information received
as a result of the request made for
SUNSI must be filed by the requestor no
later than 25 days after the requestor is
granted access to that information.
However, if more than 25 days remain
between the date the petitioner is
granted access to the information and
the deadline for filing all other
contentions (as established in the notice
of hearing or opportunity for hearing),
the petitioner may file its SUNSI
contentions by that later deadline.
G. Review of Denials of Access.
(1) If the request for access to SUNSI
is denied by the NRC staff either after
a determination on standing and need
for access, or after a determination on
trustworthiness and reliability, the NRC
staff shall immediately notify the
requestor in writing, briefly stating the
reason or reasons for the denial.
(2) The requestor may challenge the
NRC staff’s adverse determination by
filing a challenge within 5 days of
receipt of that determination with: (a)
The presiding officer designated in this
proceeding; (b) if no presiding officer
has been appointed, the Chief
Administrative Judge, or if he or she is
unavailable, another administrative
judge, or an administrative law judge
with jurisdiction pursuant to 10 CFR
2.318(a); or (c) if another officer has
been designated to rule on information
access issues, with that officer.
H. Review of Grants of Access. A party
other than the requestor may challenge
an NRC staff determination granting
access to SUNSI whose release would
harm that party’s interest independent
of the proceeding. Such a challenge
must be filed with the Chief
Administrative Judge within 5 days of
the notification by the NRC staff of its
grant of access.
If challenges to the NRC staff
determinations are filed, these
procedures give way to the normal
process for litigating disputes
concerning access to information. The
availability of interlocutory review by
the Commission of orders ruling on
such NRC staff determinations (whether
granting or denying access) is governed
by 10 CFR 2.311.3
I. The Commission expects that the
NRC staff and presiding officers (and
any other reviewing officers) will
consider and resolve requests for access
to SUNSI, and motions for protective
orders, in a timely fashion in order to
minimize any unnecessary delays in
identifying those petitioners who have
standing and who have propounded
contentions meeting the specificity and
basis requirements in 10 CFR part 2.
Attachment 1 to this Order summarizes
the general target schedule for
processing and resolving requests under
these procedures.
It is so ordered.
Dated at Rockville, Maryland, this 23rd day
of December 2009.
For the Nuclear Regulatory Commission.

By letter dated February 25, 2009,
Powertech (USA) Inc. (Powertech
(USA)) submitted a Source Materials
License application to the U.S. Nuclear
Regulatory Commission (NRC) for the
Dewey-Burdock In Situ Recovery
Facility in Fall River and Custer
Counties, South Dakota. The DeweyBurdock facility would involve the
recovery of uranium by in situ recovery
(ISR) extraction. By letter dated June 19,
2009, Powertech (USA) withdrew the
application to provide additional
information on hydrology/site
characterization, waste disposal,
location of extraction operations,
protection of water resources, and
operational issues. The application was
resubmitted on August 10, 2009. An
NRC Administrative review,
documented in a letter to Powertech
(USA) dated October 2, 2009, found the
application acceptable to begin a
technical and environmental review.
Before approving the license
application, the NRC will need to make
the findings required by the Atomic

Energy Act of 1954, as amended, and
NRC’s 10 CFR part 40 regulations. These
findings will be documented in a Safety

environmental review will also be
conducted, consistent with the
provisions of 10 CFR part 51.
The NRC has determined that
documents containing sensitive
unclassified non-safeguards information
(SUNSI) are associated with this
application. SUNSI associated with
license applications is not made
available to the general public, and is
thus not on the NRC’s Agencywide

potential parties to this proceeding may
request access to documents containing
SUNSI if needed to participate in the
proceeding.

NUCLEAR REGULATORY COMMISSION
[NRC-2009-0564]
Notice; Applications and Amendments to Facility Operating
Licenses Involving Proposed No Significant Hazards Considerations and
Containing Sensitive Unclassified Non-Safeguards Information and Order
Imposing Procedures for Access to Sensitive Unclassified Non-Safeguards
Information
I. Background
Pursuant to section 189a. (2) of the Atomic Energy Act of 1954, as
amended (the Act), the U.S. Nuclear Regulatory Commission (the
Commission or NRC staff) is publishing this notice. The Act requires
the Commission publish notice of any amendments issued, or proposed to
be issued and grants the Commission the authority to issue and make
immediately effective any amendment to an operating license upon a
determination by the Commission that such amendment involves no
significant hazards consideration, notwithstanding the pendency before
the Commission of a request for a hearing from any person.
This notice includes notices of amendments containing sensitive
unclassified non-safeguards information (SUNSI).
Notice of Consideration of Issuance of Amendments to Facility Operating
Licenses, Proposed No Significant Hazards Consideration Determination,
and Opportunity for a Hearing
The Commission has made a proposed determination that the following
amendment requests involve no significant hazards consideration. Under
the Commission's regulations in Title 10 of the Code of Federal
Regulations (10 CFR), Section 50.92, this means that operation of the
facility in accordance with the proposed amendment would not (1)
involve a significant increase in the probability or consequences of an
accident previously evaluated; or (2) create the possibility of a new
or different kind of accident from any accident previously evaluated;
or (3) involve a significant reduction in a margin of safety. The basis
for this proposed determination for each amendment request is shown
below.
The Commission is seeking public comments on this proposed
determination. Any comments received within 30 days after the date of
publication of this notice will be considered in making any final
determination.
Normally, the Commission will not issue the amendment until the
expiration of 60 days after the date of publication of this notice. The
Commission may issue the license amendment before expiration of the 60-
day period provided that its final determination is that the amendment
involves no significant hazards consideration. In addition, the
Commission may issue the amendment prior to the expiration of the 30-
day comment period should circumstances change during the 30-day
comment period such that failure to act in a timely way would result,
for example in derating or shutdown of the facility. Should the
Commission take action prior to the expiration of either the comment
period or the notice period, it will publish in the Federal Register a
notice of issuance. Should the Commission make a final No Significant
Hazards Consideration Determination, any hearing will take place after
issuance. The Commission expects that the need to take this action will
occur very infrequently.
Written comments may be submitted by mail to the Chief, Rulemaking
and Directives Branch (RDB), TWB-05-
[[Page 459]]
B01M, Division of Administrative Services, Office of Administration,
U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, and
should cite the publication date and page number of this Federal
Register notice. Written comments may also be faxed to the RDB at 301-
492-3446. Documents may be examined, and/or copied for a fee, at the
NRC's Public Document Room (PDR), located at One White Flint North,
Public File Area O1 F21, 11555 Rockville Pike (first floor), Rockville,
Maryland.
Within 60 days after the date of publication of this notice, any
person(s) whose interest may be affected by this action may file a
request for a hearing and a petition to intervene with respect to
issuance of the amendment to the subject facility operating license.
Requests for a hearing and a petition for leave to intervene shall be
filed in accordance with the Commission's ``Rules of Practice for
Domestic Licensing Proceedings'' in 10 CFR Part 2. Interested person(s)
should consult a current copy of 10 CFR 2.309, which is available at
the Commission's PDR, located at One White Flint North, Public File
Area 01F21, 11555 Rockville Pike (first floor), Rockville, Maryland, or
at https://www.nrc.gov/reading-rm/doc-collections/cfr/part002/part002-0309.html. Publicly available records will be accessible from the
Agencywide Documents Access and Management System's (ADAMS) Public
Electronic Reading Room on the Internet at the NRC Web site, https://www.nrc.gov/reading-rm.html. If a request for a hearing or petition for
leave to intervene is filed within 60 days, the Commission or a
presiding officer designated by the Commission or by the Chief
Administrative Judge of the Atomic Safety and Licensing Board Panel,
will rule on the request and/or petition; and the Secretary or the
Chief Administrative Judge of the Atomic Safety and Licensing Board
will issue a notice of a hearing or an appropriate order.
As required by 10 CFR 2.309, a petition for leave to intervene
shall set forth with particularity the interest of the petitioner in
the proceeding, and how that interest may be affected by the results of
the proceeding. The petition should specifically explain the reasons
why intervention should be permitted with particular reference to the
following general requirements: (1) The name, address, and telephone
number of the requestor or petitioner; (2) the nature of the
requestor's/petitioner's right under the Act to be made a party to the
proceeding; (3) the nature and extent of the requestor's/petitioner's
property, financial, or other interest in the proceeding; and (4) the
possible effect of any decision or order which may be entered in the
proceeding on the requestor's/petitioner's interest. The petition must
also set forth the specific contentions which the requestor/petitioner
seeks to have litigated at the proceeding.
Each contention must consist of a specific statement of the issue
of law or fact to be raised or controverted. In addition, the
requestor/petitioner shall provide a brief explanation of the bases for
the contention and a concise statement of the alleged facts or expert
opinion which support the contention and on which the requestor/
petitioner intends to rely in proving the contention at the hearing.
The requestor/petitioner must also provide references to those specific
sources and documents of which the petitioner is aware and on which the
requestor/petitioner intends to rely to establish those facts or expert
opinion. The petition must include sufficient information to show that
a genuine dispute exists with the applicant on a material issue of law
or fact. Contentions shall be limited to matters within the scope of
the amendment under consideration. The contention must be one which, if
proven, would entitle the requestor/petitioner to relief. A requestor/
petitioner who fails to satisfy these requirements with respect to at
least one contention will not be permitted to participate as a party.
Those permitted to intervene become parties to the proceeding,
subject to any limitations in the order granting leave to intervene,
and have the opportunity to participate fully in the conduct of the
hearing.
If a hearing is requested, and the Commission has not made a final
determination on the issue of no significant hazards consideration, the
Commission will make a final determination on the issue of no
significant hazards consideration. The final determination will serve
to decide when the hearing is held. If the final determination is that
the amendment request involves no significant hazards consideration,
the Commission may issue the amendment and make it immediately
effective, notwithstanding the request for a hearing. Any hearing held
would take place after issuance of the amendment. If the final
determination is that the amendment request involves a significant
hazards consideration, any hearing held would take place before the
issuance of any amendment.
All documents filed in NRC adjudicatory proceedings, including a
request for hearing, a petition for leave to intervene, any motion or
other document filed in the proceeding prior to the submission of a
request for hearing or petition to intervene, and documents filed by
interested governmental entities participating under 10 CFR 2.315(c),
must be filed in accordance with the NRC E-Filing rule (72 FR 49139,
August 28, 2007). The E-Filing process requires participants to submit
and serve all adjudicatory documents over the Internet, or in some
cases to mail copies on electronic storage media. Participants may not
submit paper copies of their filings unless they seek an exemption in
accordance with the procedures described below.
To comply with the procedural requirements of E-Filing, at least
ten (10) days prior to the filing deadline, the participant should
contact the Office of the Secretary by e-mail at
hearing.docket@nrc.gov, or by telephone at (301) 415-1677, to request
(1) a digital ID certificate, which allows the participant (or its
counsel or representative) to digitally sign documents and access the
E-Submittal server for any proceeding in which it is participating; and
(2) advise the Secretary that the participant will be submitting a
request or petition for hearing (even in instances in which the
participant, or its counsel or representative, already holds an NRC-
issued digital ID certificate). Based upon this information, the
Secretary will establish an electronic docket for the hearing in this
proceeding if the Secretary has not already established an electronic
docket.
Information about applying for a digital ID certificate is
available on NRC's public Web site at https://www.nrc.gov/site-help/e-submittals/apply-certificates.html. System requirements for accessing
the E-Submittal server are detailed in NRC's ``Guidance for Electronic
Submission,'' which is available on the agency's public Web site at
https://www.nrc.gov/site-help/e-submittals.html. Participants may
attempt to use other software not listed on the Web site, but should
note that the NRC's E-Filing system does not support unlisted software,
and the NRC Meta System Help Desk will not be able to offer assistance
in using unlisted software.
If a participant is electronically submitting a document to the NRC
in accordance with the E-Filing rule, the participant must file the
document using the NRC's online, Web-based submission form. In order to
serve documents through EIE, users will be required to install a Web
browser plug-
[[Page 460]]
in from the NRC Web site. Further information on the Web-based
submission form, including the installation of the Web browser plug-in,
is available on the NRC's public Web site at https://www.nrc.gov/site-help/e-submittals.html.
Once a participant has obtained a digital ID certificate and a
docket has been created, the participant can then submit a request for
hearing or petition for leave to intervene. Submissions should be in
Portable Document Format (PDF) in accordance with NRC guidance
available on the NRC public Web site at https://www.nrc.gov/site-help/e-submittals.html. A filing is considered complete at the time the
documents are submitted through the NRC's E-Filing system. To be
timely, an electronic filing must be submitted to the E-Filing system
no later than 11:59 p.m. Eastern Time on the due date. Upon receipt of
a transmission, the E-Filing system time-stamps the document and sends
the submitter an e-mail notice confirming receipt of the document. The
E-Filing system also distributes an e-mail notice that provides access
to the document to the NRC Office of the General Counsel and any others
who have advised the Office of the Secretary that they wish to
participate in the proceeding, so that the filer need not serve the
documents on those participants separately. Therefore, applicants and
other participants (or their counsel or representative) must apply for
and receive a digital ID certificate before a hearing request/petition
to intervene is filed so that they can obtain access to the document
via the E-Filing system.
A person filing electronically using the agency's adjudicatory E-
Filing system may seek assistance by contacting the NRC Meta System
Help Desk through the ``Contact Us'' link located on the NRC Web site
at https://www.nrc.gov/site-help/e-submittals.html, by e-mail at
MSHD.Resource@nrc.gov, or by a toll-free call at (866) 672-7640. The
NRC Meta System Help Desk is available between 8 a.m. and 8 p.m.,
Eastern Time, Monday through Friday, excluding government holidays.
Participants who believe that they have a good cause for not
submitting documents electronically must file an exemption request, in
accordance with 10 CFR 2.302(g), with their initial paper filing
requesting authorization to continue to submit documents in paper
format. Such filings must be submitted by: (1) First class mail
addressed to the Office of the Secretary of the Commission, U.S.
Nuclear Regulatory Commission, Washington, DC 20555-0001, Attention:
Rulemaking and Adjudications Staff; or (2) courier, express mail, or
expedited delivery service to the Office of the Secretary, Sixteenth
Floor, One White Flint North, 11555 Rockville Pike, Rockville, Maryland
20852, Attention: Rulemaking and Adjudications Staff. Participants
filing a document in this manner are responsible for serving the
document on all other participants. Filing is considered complete by
first-class mail as of the time of deposit in the mail, or by courier,
express mail, or expedited delivery service upon depositing the
document with the provider of the service. A presiding officer, having
granted an exemption request from using E-Filing, may require a
participant or party to use E-Filing if the presiding officer
subsequently determines that the reason for granting the exemption from
use of E-Filing no longer exists.
Documents submitted in adjudicatory proceedings will appear in
NRC's electronic hearing docket which is available to the public at
https://ehd.nrc.gov/EHD_Proceeding/home.asp, unless excluded pursuant
to an order of the Commission, or the presiding officer. Participants
are requested not to include personal privacy information, such as
social security numbers, home addresses, or home phone numbers in their
filings, unless an NRC regulation or other law requires submission of
such information. With respect to copyrighted works, except for limited
excerpts that serve the purpose of the adjudicatory filings and would
constitute a Fair Use application, participants are requested not to
include copyrighted materials in their submission.
Petitions for leave to intervene must be filed no later than 60
days from January 5, 2010. Non-timely filings will not be entertained
absent a determination by the presiding officer that the petition or
request should be granted or the contentions should be admitted, based
on a balancing of the factors specified in 10 CFR 2.309(c)(1)(i)-
(viii).
For further details with respect to this amendment action, see the
application for amendment which is available for public inspection at
the Commission's PDR, located at One White Flint North, Public File

Carolina Power & Light Company, Docket No. 50-261, H. B. Robinson Steam
Electric Plant (HBRSEP) Unit No. 2, Darlington County, South Carolina
Date of amendment request: June 19, 2009, as supplemented by letter
dated October 20, 2009.
Description of amendment request: This amendment request contains
sensitive unclassified non-safeguards information (SUNSI). The proposed
amendment would revise TS 3.3.1, ``Reactor Protection System
Instrumentation.'' The proposed change revises the requirements related
to the reactor protection system interlock for the turbine trip input
to the reactor protection system.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The Proposed Change Does Not Involve a Significant Increase
in the Probability or Consequences of an Accident Previously
Evaluated.
The proposed change provides revised requirements for the
reactor protection system interlock associated with the turbine trip
protection function. The proposed change will allow the interlock
for turbine trip function to be raised from the current interlock
setting of nominally 10 percent reactor power to nominally 40
percent reactor power.
This change will allow the reactor to continue operating safely
at power levels up to nominally 40 percent when the turbine is not
operating. The applicable accident analyses, as described in the
HBRSEP, Unit No. 2, Updated Final Safety Analysis Report (UFSAR)
have been reviewed. The turbine trip input to reactor trip has been
verified to be either not used in the accident analyses or that the
change does not adversely affect the analyses results and
conclusion. Therefore, it is concluded that the consequences as
described in the UFSAR accident analyses are unaffected by the
proposed change.
An analysis of plant response to a turbine trip at nominally 40
percent power provided with the amendment request shows that the
applicable acceptance criteria are met. Specifically, analysis has
shown that a turbine trip without a reactor trip below 40 percent
power does not challenge the pressurizer PORVs [power operated
relief valves] or the steam generator safety valves; thereby, not
adversely affecting the probability of a small break LOCA [loss of
coolant accident] due to a stuck open PORV, or an excessive cooldown
event due to a stuck open steam generator safety valve. As a result,
the probability of any accident
[[Page 461]]
previously evaluated is not significantly increased by the proposed
changes.
Therefore, operation of the facility in accordance with the
proposed amendment does not involve a significant increase in the
probability or consequences of an accident previously evaluated.
2. The Proposed Change Does Not Create the Possibility of a New
or Different Kind of Accident From Any Previously Evaluated.
As described above, the proposed change provides revised
requirements for the reactor protection system interlock associated
with the turbine trip protection function. The proposed change will
allow the interlock for turbine trip function to be raised from the
current interlock setting of nominally 10 percent reactor power to
nominally 40 percent reactor power.
No new accident initiators or precursors are introduced by the
proposed change. Changing the interlock for the reactor trip on
turbine trip from P-7 to P-8 changes the power level associated with
enabling and disabling the reactor trip on turbine trip function.
The turbine pressure input to the reactor protection system
permissive is not an accident initiator. The change does not affect
how the associated trip functional units operate or function. The
changes do not create the possibility of a new or different kind of
accident from any previously evaluated because these interlock
changes do not affect the way that the associated trip functional
units operate or function.
Therefore, operation of the facility in accordance with the
proposed amendment would not create the possibility of a new or
different kind of accident from any previously evaluated.
3. The Proposed Change Does Not Involve a Significant Reduction
in the Margin of Safety.
As described above, the proposed change provides revised
requirements for the reactor protection system interlock associated
with the turbine trip protection function. The proposed change will
allow the interlock for the turbine trip function to be raised from
the current interlock setting of nominally 10 percent reactor power
to nominally 40 percent reactor power.
Also, as previously described, this change will allow the
reactor to continue operating safely at power levels up to nominally
40 percent when the turbine is not operating. The applicable UFSAR
accident analyses have been reviewed and it is concluded that the
accident analyses are unaffected by the proposed change. An analysis
of plant response to a turbine trip at nominally 40 percent power
shows that the applicable acceptance criteria are met. Based on
these evaluations, the margins of safety that could potentially have
been impacted by the proposed change associated with the reactor,
which include departure from nucleate boiling (DNB) and fuel
temperature margins, and the margin of safety associated with
reactor coolant system integrity, are not affected.
Therefore, operation of the facility in accordance with the
proposed amendment would not involve a significant reduction in the
margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Entergy Nuclear Vermont Yankee, LLC and Entergy Nuclear Operations,
Inc., Docket No. 50-271, Vermont Yankee Nuclear Power Station, Vernon,
Vermont
Date of amendment request: October 27, 2009.
Description of amendment request: This amendment request contains
sensitive unclassified non-safeguards information (SUNSI). This
amendment request would change the Technical Specifications to provide
revised values for the Safety Limit Minimum Critical Power Ratio
(SLMCPR) for both single and dual recirculation loop operation.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The operation of Vermont Yankee Nuclear Power Station in
accordance with the proposed amendment will not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
The basis of the Safety Limit MCPR (SLMCPR) is to ensure no
mechanistic fuel damage is calculated to occur if the limit is not
violated. The new SLMCPR values preserve the existing margin to
transition boiling and probability of fuel damage is not increased.
The derivation of the revised SLMCPR for Vermont Yankee for
incorporation into the Technical Specifications and its use to
determine plant and cycle-specific thermal limits has been performed
using NRC approved methods. These plant-specific calculations are
performed each operating cycle and if necessary, will require future
changes to these values based upon revised core designs. The revised
SLMCPR values do not change the method of operating the plant and
have no effect on the probability of an accident initiating event or
transient.
Based on the above, Vermont Yankee has concluded that the
proposed change will not result in a significant increase in the
probability or consequences of an accident previously evaluated.
2. The operation of Vermont Yankee Nuclear Power Station in
accordance with the proposed amendment will not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
The proposed changes result only from a specific analysis for
the Vermont Yankee core reload design. These changes do not involve
any new or different methods for operating the facility. No new
initiating events or transients result from these changes.
Based on the above, Vermont Yankee has concluded that the
proposed change will not create the possibility of a new or
different kind of accident from those previously evaluated.
3. The operation of Vermont Yankee Nuclear Power Station in
accordance with the proposed amendment will not involve a
significant reduction in a margin of safety.
The new SLMCPR is calculated using NRC approved methods with
plant and cycle specific parameters for the current core design. The
SLMCPR value remains conservative enough to ensure that greater than
99.9% of all fuel rods in the core will avoid transition boiling if
the limit is not violated, thereby preserving the fuel cladding
integrity. The operating MCPR limit is set appropriately above the
safety limit value to ensure adequate margin when the cycle specific
transients are evaluated. Accordingly, the margin of safety is
maintained with the revised values.
As a result, Vermont Yankee has determined that the proposed
change will not result in a significant reduction in the margin of
safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Docket No. 50-416, Grand Gulf Nuclear Station, Unit 1, Claiborne
County, Mississippi
Date of amendment request: October 27, 2009.
Description of amendment request: This amendment request contains
sensitive unclassified non-safeguards information (SUNSI). The proposed
amendment revises the Technical Specifications to increase the two
recirculation loop minimum critical power ratio (MCPR) safety limit
from 1.08 to 1.09 and the single recirculation loop MCPR safety limit
from 1.10 to 1.12.
[[Page 462]]
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The Minimum Critical Power Ratio (MCPR) limit is defined in the
Bases to Technical Specification 2.1.1.2 as that limit, ``that, in
the event of an AOO [(Anticipated Operational Occurrence)] from the
limiting condition of operation, at least 99.9% of the fuel rods in
the core would be expected to avoid boiling transition.'' The MCPR
safety limit satisfies the requirements of General Design Criterion
10 of Appendix A to 10CFR50 regarding acceptable fuel design limits.
The MCPR safety limit is reevaluated for each reload using NRC-
approved methodologies. The analyses for GGNS [Grand Gulf Nuclear
Station] Cycle 18 have concluded that a two-loop MCPR safety limit
of 1.09, based on the application of Global Nuclear Fuels' NRC
approved MCPR safety limit methodology, will ensure that this
acceptance criterion is met. For single-loop operation, a MCPR
safety limit of 1.12, also ensures that this acceptance criterion is
met. The MCPR operating limits are presented and controlled in
accordance with the GGNS Core Operating Limits Report (COLR).
The requested Technical Specification changes do not involve any
plant modifications or operational changes that could affect system
reliability or performance or that could affect the probability of
operator error. The requested changes do not affect any postulated
accident precursors, do not affect any accident mitigating systems,
and do not introduce any new accident initiation mechanisms.
Therefore, the changes to the Minimum Critical Power Ratio
safety limit do not involve a significant increase in the
probability or consequences of any accident previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
The GNF2 fuel to be used in Cycle 18 is of a design compatible
with the co-resident GE14 and ATRIUM-10 fuel. Therefore, the
introduction of GNF2 fuel into the Cycle 18 core will not create the
possibility of a new or different kind of accident. The proposed
changes do not involve any new modes of operation, any changes to
setpoints, or any plant modifications. The proposed revised MCPR
safety limits have accounted for the mixed fuel core and have been
shown to be acceptable for Cycle 18 operation. Compliance with the
criterion for incipient boiling transition continues to be ensured.
The core operating limits will continue to be developed using NRC
approved methods which also account for the mixed fuel core design.
The proposed MCPR safety limits or methods for establishing the core
operating limits do not result in the creation of any new precursors
to an accident.
Therefore, this change does not create the possibility of a new
or different kind of accident from any previously evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The MCPR safety limits have been evaluated in accordance with
Global Nuclear Fuels NRC-approved cycle-specific safety limit
methodology to ensure that during normal operation and during AOO's
at least 99.9% of the fuel rods in the core are not expected to
experience transition boiling. The proposed revised MCPR safety
limits have accounted for the mixed fuel core and have been shown to
be acceptable for Cycle 18 operation. Compliance with the criterion
for incipient boiling transition continues to be ensured. On this
basis, the implementation of the change to the MCPR safety limits
does not involve a significant reduction in a margin of safety.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Docket No. 50-416, Grand Gulf Nuclear Station, Unit 1, Claiborne
County, Mississippi
Date of amendment request: November 3, 2009.
Description of amendment request: This amendment request contains
sensitive unclassified non-safeguards information (SUNSI). The proposed
amendment revises the Technical Specifications (TSs) to reflect the
installation of the digital General Electric--Hitachi Nuclear
Measurement Analysis and Control (NUMAC) Power Range Neutron Monitoring
(PRNM) System.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the proposed amendment involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The probability (frequency of occurrence) of design basis
accidents (DBAs) occurring is not affected by the NUMAC PRNM System,
since the system does not interact with equipment whose failure
could cause an accident. Compliance with the regulatory criteria
established for plant equipment are maintained with the installation
of the upgraded NUMAC PRNM System. Scram setpoints in the NUMAC PRNM
System are established such that the analytical limits are met.
The unavailability of the new NUMAC PRNM System is equal to or
less than the existing system and, as a result, the scram
reliability is equal to or better than the existing analog power
system. No new challenges to safety-related equipment result from
the NUMAC PRNM System modification. Therefore, the proposed change
does not involve a significant increase in the probability of an
accident previously evaluated.
The proposed change replaces the current Option E-I-A stability
solution with an NRC-approved Option III long-term stability
solution. The NUMAC PRNM hardware incorporates the Oscillation Power
Range Monitor (OPRM) Option III detect-and-suppress solution, which
has been previously reviewed and approved by the NRC. The OPRM meets
[10 CFR Part 50, Appendix A] General Design Criterion (GDC) 10,
Reactor Design, and GDC 12, Suppression of Reactor Power
Oscillations, requirements by automatically detecting and
suppressing design basis thermal-hydraulic oscillations prior to
exceeding the fuel Minimum Critical Power Ratio (MCPR) Safety Limit.
Based on the above, installation of the new NUMAC PRNM System
with the OPRM Option III stability solution integrated into the
NUMAC PRNM equipment does not increase the probability or
consequences of an accident previously evaluated.
2. Does the proposed amendment create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No.
The components of the NUMAC PRNM System are equivalent or of
better design and qualification criteria than those currently
installed and utilized in the plant. No new operating mode, safety-
related equipment lineup, accident scenario, or interaction mode not
reviewed and approved as part of the design and licensing of the
NUMAC PRNM System has been identified. Therefore, the NUMAC PRNM
System retrofit does not adversely affect plant equipment.
The new NUMAC PRNM System uses digital equipment that has
software-controlled digital processing compared to the existing
power range system that uses mostly analog and discrete component
processing. Specific failures of hardware and potential software
common-cause failures are different from the existing system. The
effects of potential software common-cause failure are mitigated by
specific hardware design and
[[Page 463]]
system architecture as discussed in Section 6.0 of [GE Nuclear
Energy Licensing Topical Report] NEDC-32410P-A. Failure(s) of the
system have the same overall effect as the present design. No new or
different kinds of accidents are introduced. Therefore, the NUMAC
PRNM System does not adversely effect plant equipment.
The currently installed Average Power Range Monitoring (APRM)
system is replaced with a NUMAC PRNM System that performs the
existing power range monitoring functions and adds an OPRM to react
automatically to potential reactor thermal-hydraulic instabilities.
Based on the above, the proposed change does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
3. Does the proposed amendment involve a significant reduction
in a margin of safety?
Response: No.
The proposed TS changes associated with the NUMAC PRNM System
retrofit implement the constraints of the NUMAC PRNM System design
and related stability analyses. The NUMAC PRNM System change does
not impact reactor operating parameters or the functional
requirements of the APRM system. The replacement equipment continues
to provide information, enforce control rod blocks, and initiate
reactor scrams under appropriate specified conditions. The proposed
change does not reduce safety margins. The replacement APRM
equipment has improved channel trip accuracy compared to the current
analog system, and meets or exceeds system requirements previously
assumed in setpoint analysis. Thus, the ability of the new equipment
to enforce compliance with margins of safety equals or exceeds the
ability of the equipment which it replaces.
Therefore, the proposed changes do not involve a reduction in a
margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Exelon Generation Company, LLC, Docket Nos. 50-373 and 50-374, LaSalle
County Station, Units 1 and 2, LaSalle County, Illinois
Date of amendment request: October 5, 2009.
Description of amendment request: This amendment request contains
sensitive unclassified non-safeguards information (SUNSI). The
amendment(s) would revise Technical Specification (TS) 4.3.1,
``Criticality,'' to address a non-conservative TS. The proposed change
addresses the Boraflex degradation issue in the LaSalle County Station
(LSCS) Unit 2 spent fuel storage racks by revising TS Section 4.3.1 to
allow the use of NETCO-SNAP-IN[reg] rack inserts in LSCS Unit 2 spent
fuel storage rack cells as a replacement for the neutron absorbing
properties of the existing Boraflex panels.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The proposed change adds an additional requirement to TS Section
4.3.1 to install a NETCO-SNAP-IN[reg] rack insert in spent fuel
storage rack cells that cannot otherwise maintain the requirements
of TS Section 4.3.1.1.a to ensure that the effective neutron
multiplication factor, Keff, is less than or equal to
0.95, if the spent fuel pool (SFP) is fully flooded with unborated
water. The proposed change also includes a revision to TS Section
4.3.1 to specify the bounding reactivity fuel design allowed for
storage in the Unit 1 and Unit 2 SFPs. Since the proposed change
pertains only to the SFP, only those accidents that are related to
movement and storage of fuel assemblies in the SFP could be
potentially affected by the proposed change.
The current licensing basis for the LSCS Unit 2 SFP credits the
neutron absorbing properties of the Boraflex neutron poison material
in the spent fuel storage racks. The current licensing basis
demonstrates: (1) Adequate margin to criticality for spent fuel
storage rack cells that credit the neutron absorption capabilities
of Boraflex, (2) adequate margin for fuel assemblies inadvertently
placed into locations adjacent to the spent fuel storage racks, and
(3) adequate margin for assemblies accidentally dropped onto the
spent fuel storage racks. Therefore, the probability that a
misplaced fuel assembly would result in an inadvertent criticality
is unchanged since the process and procedural controls governing
fuel movement in the SFP will not be changed. The dose consequences
of the most limiting drop of a fuel assembly in the SFP is limited
by the number of the fuel rods damaged and other engineered features
unaffected by the proposed change, including the fuel design, fuel
decay time, water level in the SFP, water temperature of the SFP,
and the engineering features of the Reactor Building Ventilation
System.
The installation of NETCO-SNAP-IN[reg] rack inserts does not
result in a significant increase in the probability of an accident
previously analyzed. The revised criticality analysis takes no
credit for the Boraflex material. The use of a rack insert provides
an alternative neutron absorber to take the place of the degraded
Boraflex material, without removal of the existing Boraflex. The
probability that a fuel assembly would be dropped is unchanged by
the installation of the NETCO-SNAP-IN[reg] rack inserts. These
events involve failures of administrative controls, human
performance, and equipment failures that are unaffected by the
presence or absence of Boraflex and the rack inserts.
The installation of NETCO-SNAP-IN[reg] rack inserts does not
result in a significant increase in the consequence of an accident
previously analyzed. A criticality analysis has been prepared to
demonstrate adequate margin to criticality for spent fuel storage
rack cells with rack inserts in the LSCS Unit 2 SFP, and adequate
criticality margin for assemblies accidentally dropped onto the
spent fuel storage racks.
The installation of NETCO-SNAP-IN@ rack inserts does not affect
the consequences of a dropped fuel assembly. The consequences of
dropping a fuel assembly onto any other fuel assembly or other
structure are unaffected by the change. The consequences of dropping
a fuel assembly onto a spent fuel storage rack cell with a rack
insert are bounded by the event of dropping an assembly onto another
assembly, both for criticality and for radiological consequences.
For criticality, the effects on Keff of dropping a fuel
assembly have been evaluated and are acceptable. For radiological
consequences, the number of rods damaged when a fuel assembly is
accidentally dropped onto a spent fuel storage rack cell with or
without a rack insert is bounded by the number of rods damaged by an
assembly dropped onto another assembly. The change does not affect
the effectiveness of the other engineered design features to limit
the offsite dose consequences of the limiting fuel assembly drop
accident.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
Onsite storage of spent fuel assemblies in the SFP is a normal
activity for which LSCS has been designed and licensed. As part of
assuring that this normal activity can be performed without
endangering public health and safety, the ability to safely
accommodate different possible accidents in the SFP, such as
dropping a fuel assembly or misloading a fuel assembly, have been
analyzed. The proposed spent fuel storage configuration does not
change the methods of fuel movement or spent fuel storage. The
proposed change allows for continued use of spent fuel storage rack
cells that have been determined unusable based on the degradation of
Boraflex within those spent fuel storage rack cells. The rack
inserts are passive devices. These devices, when inside a spent fuel
storage rack cell, perform the same function as the Boraflex in that
cell without the potential for degradation. These devices do not add
any limiting structural loads or affect the removal of decay heat
from
[[Page 464]]
the assemblies. No change in total heat load in the SFP is being
made. The devices are resistant to corrosion and will maintain their
structural integrity over the life of the SFP. An accidental fuel
assembly drop does not challenge their structural integrity. The
existing fuel handling accident, which assumes the drop of a fuel
assembly, bounds the drop of a rack insert and/or rack insert
installation tool. This change does not create the possibility of a
misloaded assembly into a spent fuel storage rack cell.
The misloading of a more reactive assembly targeted for
placement in the LSCS Unit 1 SFP or the LSCS Unit 2 SFP Boraflex
region in a rack insert region of the LSCS Unit 2 SFP has been
prevented since the most reactive fuel assembly at LSCS is bounded
by the rack insert criticality analysis, and the most reactive fuel
assembly allowed for future insertion in either the Unit 1 or Unit 2
SFP is being limited to the reference bounding ATRIUM-10 fuel
assembly.
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any accident previously
evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
LSCS TS 4.3.1.1 requires the spent fuel storage racks to
maintain the effective neutron multiplication factor,
Keff, less than or equal to 0.95 when fully flooded with
unborated water, which includes an allowance for uncertainties.
Therefore, for criticality, the required safety margin is 5%
including a conservative margin to account for engineering and
manufacturing uncertainties.
The proposed change provides an alternative method to ensure
that Keff continues to be less than or equal to 0.95,
thus preserving the required safety margin of 5%. The criticality
analysis demonstrates the required margin to criticality of 5%,
including a conservative margin to account for engineering and
manufacturing uncertainties, is maintained assuming an infinite
array of fuel with all fuel at the peak reactivity. In addition, the
margin of safety for radiological consequences of a dropped fuel
assembly are unchanged because the event involving a dropped fuel
assembly onto a spent fuel storage rack cell containing a fuel
assembly with a rack insert is bounded by the consequences of a
dropped fuel assembly without a rack insert. The proposed change
also maintains the capacity of the Unit 2 SFP to be no more than
4078 fuel assemblies.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

PSEG Nuclear LLC, Docket No. 50-272, Salem Nuclear Generating Station,
Unit No. 1, Salem County, New Jersey
Date of amendment request: October 8, 2009.
Description of amendment request: This amendment request contains
sensitive unclassified non-safeguards information (SUNSI). The proposed
amendment would revise Technical Specification (TS) 6.8.4.i, ``Steam
Generator (SG) Program,'' by adding a one-time alternate repair
criterion that excludes certain portions of the tube below the top of
the SG tubesheet from periodic SG tube inspections. In addition, the
proposed amendment would revise TS 6.9.10, ``Steam Generator Tube
Inspection Report,'' to provide reporting requirements specific to the
alternate repair criteria. The proposed amendment is supported by
Westinghouse Electric Company, LLC Topical Report WCAP-17071-P, ``H*:
Alternate Repair Criteria for the Tubesheet Expansion Region in Steam
Generators with Hydraulically Expanded Tubes (Model F).'' H*
(pronounced ``H star'') is the length of hydraulically expanded SG tube
that must remain intact within the tubesheet in order for the joint to
resist pullout and leakage due to normal operating and accident
conditions.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
consideration, which is presented below:
1. The proposed changes do not involve a significant increase in
the probability or consequences of an accident previously evaluated.
The previously analyzed accidents are initiated by the failure
of plant structures, systems, or components. The proposed change
that alters the steam generator (SG) inspection and reporting
criteria does not have a detrimental impact on the integrity of any
plant structure, system, or component that initiates an analyzed
event. The proposed change will not alter the operation of, or
otherwise increase the failure probability of any plant equipment
that initiates an analyzed accident.
Of the applicable accidents previously evaluated, the limiting
transients with consideration to the proposed change to the SG tube
inspection and repair criteria are the steam generator tube rupture
(SGTR) event, the steam line break (SLB), and the feed line break
(FLB) postulated accidents.
During the SGTR event, the required structural integrity margins
of the SG tubes and the tube-to-tubesheet joint over the H* distance
will be maintained. Tube rupture in tubes with cracks within the
tubesheet is precluded by the constraint provided by the presence of
the tubesheet and the tube-to-tubesheet joint. Tube burst cannot
occur within the thickness of the tubesheet. The tube-to-tubesheet
joint constraint results from the hydraulic expansion process,
thermal expansion mismatch between the tube and tubesheet, and from
the differential pressure between the primary and secondary side,
and tubesheet rotation. Based on this design, the structural margins
against burst, as discussed in Regulatory Guide (RG) 1.121, ``Bases
for Plugging Degraded PWR [pressurized-water reactor] Steam
Generator Tubes,'' and Technical Specification 6.8.4.i, are
maintained for both normal and postulated accident conditions.
The proposed change has no impact on the structural or leakage
integrity of the portion of the tube outside of the tubesheet. The
proposed change maintains structural and leakage integrity of the SG
tubes consistent with the performance criteria of Technical
Specification 6.8.4.i. Therefore, the proposed change results in no
significant increase in the probability of the occurrence of a SGTR
accident.
At normal operating pressures, leakage from tube degradation
below the proposed limited inspection depth is limited by the tube-
to-tubesheet crevice. Consequently, negligible normal operating
leakage is expected from degradation below the inspected depth
within the tubesheet region. The consequences of an SGTR event are
not affected by the primary-to-secondary leakage flow during the
event as primary-to-secondary leakage flow through a postulated tube
that has been pulled out of the tubesheet is essentially equivalent
to a severed tube. Therefore, the proposed change does not result in
a significant increase in the consequences of a SGTR[.]
The probability of a SLB is unaffected by the potential failure
of a steam generator tube as the failure of tube is not an initiator
for a SLB event.
The leakage factor of 2.16 for Salem Unit 1, for a postulated
SLB/FLB, has been calculated as shown in Table 9-7 of WCAP-17071-P
as revised by the response to RAI [request for additional
information] 24 (Attachment 7 [to the application dated October 8,
2009]). Through application of the limited tubesheet inspection
scope, the existing operating leakage limit provides assurance that
excessive leakage (i.e., greater than accident analysis assumptions)
will not occur. The accident analysis calculations have an
assumption of 0.6 [gallons per minute (gpm)] at room temperature
(gpmRT) primary-to-secondary leakage in a single SG and 1 gpm at
room temperature (gpmRT) total primary-to-secondary leakage for all
SGs. This apportioned primary-to-secondary leakage is used in the
Main Steam Line Break and Locked Rotor accidents. Primary-to-
secondary leakage of 1 gpm at room temperature (gpmRT) in a single
SG is used in the Control Rod Ejection (CRE) accident.
No leakage factor will be applied to the locked rotor or control
rod ejection transients due to their short duration.
[[Page 465]]
The TS operational leak rate limit is 150 gallons per day (gpd)
(0.104 gpmRT). The maximum accident leak rate ratio for Salem Unit 1
is 2.16. Consequently, this results in significant margin between
the conservatively estimated accident leakage and the allowable
accident leakage.
For the condition monitoring (CM) assessment, the component of
leakage from the prior cycle from below the H* distance will be
multiplied by a factor of 2.16 and added to the total leakage from
any other source and compared to the allowable accident induced
leakage limit. For the operational assessment (OA), the difference
in the leakage between the allowable leakage and the accident
induced leakage from sources other than the tubesheet expansion
region will be divided by 2.16 and compared to the observed
operational leakage.
Based on the above, the proposed change does not involve a
significant increase in the probability or consequences of an
accident previously evaluated.
2. The proposed changes do not create the possibility of a new
or different kind of accident from any previously evaluated.
The proposed change that alters the steam generator inspection
and reporting criteria does not introduce any new equipment, create
new failure modes for existing equipment, or create any new limiting
single failures. Plant operation will not be altered, and all safety
functions will continue to perform as previously assumed in accident
analyses. Therefore, the proposed change does not create the
possibility of a new or different kind of accident from any
previously evaluated.
3. The proposed changes do not involve a significant reduction
in the margin of safety.
The proposed change defines the safety significant portion of
the tube that must be inspected and repaired (plugged). WCAP-17071-P
identifies the specific inspection depth below which any type tube
degradation shown to have no impact on the performance criteria in
[Nuclear Energy Institute (NEI) document] NEI 97-06 [Revision] 2,
``Steam Generator Program Guidelines.''
The proposed change that alters the steam generator inspection
and reporting criteria maintains the required structural margins of
the SG tubes for both normal and accident conditions. Nuclear Energy
Institute 97-06, ``Steam Generator Program Guidelines,'' and NRC
Regulatory Guide (RG) 1.121, ``Bases for Plugging Degraded PWR Steam
Generator Tubes,'' are used as the bases in the development of the
limited hot leg tubesheet inspection depth methodology for
determining that SG tube integrity considerations are maintained
within acceptable limits. RG 1.121 describes a method acceptable to
the NRC for meeting General Design Criteria (GDC) 14, ``Reactor
Coolant Pressure Boundary,'' GDC 15, ``Reactor Coolant System
Design,'' GDC 31, ``Fracture Prevention of Reactor Coolant Pressure
Boundary,'' and GDC 32, ``Inspection of Reactor Coolant Pressure
Boundary,'' by reducing the probability and consequences of a SGTR.
RG 1.121 concludes that by determining the limiting safe conditions
for tube wall degradation, the probability and consequences of a
SGTR are reduced. This RG uses safety factors on loads for tube
burst that are consistent with the requirements of Section III of
the American Society of Mechanical Engineers (ASME) Code.
For axially oriented cracking located within the tubesheet, tube
burst is precluded due to the presence of the tubesheet. For
circumferentially oriented cracking, Westinghouse WCAP-17071-P
defines a length of degradation-free expanded tubing that provides
the necessary resistance to tube pullout due to the pressure induced
forces, with applicable safety factors applied. Application of the
limited hot and cold leg tubesheet inspection criteria will preclude
unacceptable primary-to-secondary leakage during all plant
conditions. The methodology for determining leakage as described in
WCAP-1707[1]-P shows that significant margin exists between an
acceptable level of leakage during normal operating conditions that
ensures meeting the accident-induced leakage assumptions and the TS
leakage limit of 150 gpd.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

A. This Order contains instructions regarding how potential parties
to this proceeding may request access to documents containing Sensitive
Unclassified Non-Safeguards Information (SUNSI).
B. Within 10 days after publication of this notice of hearing and
opportunity to petition for leave to intervene, any potential party who
believes access to SUNSI is necessary to respond to this notice may
request such access. A ``potential party'' is any person who intends to
participate as a party by demonstrating standing and filing an
admissible contention under 10 CFR 2.309. Requests for access to SUNSI
submitted later than 10 days after publication will not be considered
absent a showing of good cause for the late filing, addressing why the
request could not have been filed earlier.
[[Page 466]]
C. The requestor shall submit a letter requesting permission to
access SUNSI to the Office of the Secretary, U.S. Nuclear Regulatory
Commission, Washington, DC 20555-0001, Attention: Rulemakings and
Adjudications Staff, and provide a copy to the Associate General
Counsel for Hearings, Enforcement and Administration, Office of the
General Counsel, Washington, DC 20555-0001. The expedited delivery or
courier mail address for both offices is: U.S. Nuclear Regulatory
Commission, 11555 Rockville Pike, Rockville, Maryland 20852. The e-mail
address for the Office of the Secretary and the Office of the General
Counsel are Hearing.Docket@nrc.gov and OGCmailcenter@nrc.gov,
respectively.\1\ The request must include the following information:
---------------------------------------------------------------------------
\1\ While a request for hearing or petition to intervene in this
proceeding must comply with the filing requirements of the NRC's
``E-Filing Rule,'' the initial request to access SUNSI under these
procedures should be submitted as described in this paragraph.
---------------------------------------------------------------------------
(1) A description of the licensing action with a citation to this
Federal Register notice;
(2) The name and address of the potential party and a description
of the potential party's particularized interest that could be harmed
by the action identified in C.(1);
(3) The identity of the individual or entity requesting access to
SUNSI and the requestor's basis for the need for the information in
order to meaningfully participate in this adjudicatory proceeding. In
particular, the request must explain why publicly available versions of
the information requested would not be sufficient to provide the basis
and specificity for a proffered contention;
D. Based on an evaluation of the information submitted under
paragraph C.(3) the NRC staff will determine within 10 days of receipt
of the request whether:
(1) There is a reasonable basis to believe the petitioner is likely
to establish standing to participate in this NRC proceeding; and
(2) The requestor has established a legitimate need for access to
SUNSI.
E. If the NRC staff determines that the requestor satisfies both
D.(1) and D.(2) above, the NRC staff will notify the requestor in
writing that access to SUNSI has been granted. The written notification
will contain instructions on how the requestor may obtain copies of the
requested documents, and any other conditions that may apply to access
to those documents. These conditions may include, but are not limited
to, the signing of a Non-Disclosure Agreement or Affidavit, or
Protective Order \2\ setting forth terms and conditions to prevent the
unauthorized or inadvertent disclosure of SUNSI by each individual who
will be granted access to SUNSI.
---------------------------------------------------------------------------
\2\ Any motion for Protective Order or draft Non-Disclosure
Affidavit or Agreement for SUNSI must be filed with the presiding
officer or the Chief Administrative Judge if the presiding officer
has not yet been designated, within 30 days of the deadline for the
receipt of the written access request.
---------------------------------------------------------------------------
F. Filing of Contentions. Any contentions in these proceedings that
are based upon the information received as a result of the request made
for SUNSI must be filed by the requestor no later than 25 days after
the requestor is granted access to that information. However, if more
than 25 days remain between the date the petitioner is granted access
to the information and the deadline for filing all other contentions
(as established in the notice of hearing or opportunity for hearing),
the petitioner may file its SUNSI contentions by that later deadline.
G. Review of Denials of Access.
(1) If the request for access to SUNSI is denied by the NRC staff
either after a determination on standing and need for access, or after
a determination on trustworthiness and reliability, the NRC staff shall
immediately notify the requestor in writing, briefly stating the reason
or reasons for the denial.
(2) The requestor may challenge the NRC staff's adverse
determination by filing a challenge within 5 days of receipt of that
determination with: (a) The presiding officer designated in this
proceeding; (b) if no presiding officer has been appointed, the Chief
Administrative Judge, or if he or she is unavailable, another
administrative judge, or an administrative law judge with jurisdiction
pursuant to 10 CFR 2.318(a); or (c) if another officer has been
designated to rule on information access issues, with that officer.
