design function. Construction FFD
requirements are not related to or used
to establish the design bases of an SSC
nor are they considered in the safety
analyses. Furthermore, the requested
exemption does not exceed or alter a
design basis or safety limit. Therefore,
granting this exemption does not
involve a significant reduction in a
margin of safety.
As all of the responses to the above
questions are in the negative, under 10
CFR 51.22(c)(25)(i), the NRC staff has
concluded that the requested exemption
involves no significant hazards
consideration.
To grant the exemption, the requested
exemption must not involve a
significant change in the types or
significant increase in the amounts of
any effluents that may be released
offsite [10 CFR 51.22(c)(25)(ii)]. The
requested exemption does not alter the
design, function, or operation of any
plant equipment. There are no changes
to effluent types, plant radiological or
non-radiological effluent release
quantities, any effluent release path, or
the functionality of any design or
operational features credited with
controlling the release of effluents
during plant operation or construction.
Therefore, the NRC concludes that the
proposed exemption does not involve a
significant change in the types or
significant increase in the amounts of
any effluents that may be released
offsite.
The requested exemption must not
involve a significant increase in
individual or cumulative public or
occupational radiation exposure [10
CFR 51.22(c)(25)(iii)]. There are no
changes to plant radiation zones, nor
any change to controls required under
10 CFR part 20, ‘‘Standards for
Protection Against Radiation,’’ which
preclude a significant increase in
occupational radiation exposure.
Therefore, the NRC concludes that the
proposed exemption does not involve a
significant increase in individual or
cumulative public or occupational
radiation exposure.
To grant the exemption, the requested
exemption must not involve a
significant construction impact [10 CFR
51.22(c)(25)(iv)]. The requested
exemption does not alter the materials
or methods of constructing or testing of
any SSCs. No change to the construction
of the facility is being made as a result
of this exemption. Therefore, the NRC
concludes that the proposed exemption
does not involve a significant
construction impact.
To grant the exemption, the requested
exemption must not involve a
VerDate Sep<11>2014
18:23 Jun 11, 2019
Jkt 247001
significant increase in the potential for
or consequences from radiological
accidents [10 CFR 51.22(c)(25)(v)]. The
requested exemption does not alter the
design, function, or operation of any
plant equipment. There are no changes
to plant radiation zones, nor any change
to controls required under 10 CFR part
20 which preclude a significant increase
in occupational radiation exposure.
Therefore, the NRC concludes that the
proposed exemption does not involve a
significant increase in the potential for
or consequences from radiological
accidents.
The requested exemption involves
employment suitability requirements
related to FFD programs, as obtaining an
FFD authorization is a prerequisite for
working on or directing work on safetyor security-related SSCs [10 CFR
51.22(c)(25)(vi)(E)].
Based on the evaluation above, the
NRC staff concludes that the exemption
meets the criteria of 10 CFR 51.22(c).
Therefore, in accordance with 10 CFR
51.22(b), an environmental impact
statement or environmental assessment
is not required for the NRC staff’s
consideration of this exemption request.
IV. Conclusions
Accordingly, the Commission has
determined that, pursuant to 10 CFR
26.9, the exemption is authorized by
law, will not endanger life or property
or the common defense and security,
and is otherwise in the public interest.
Therefore, the Commission hereby
grants SNC an exemption from 10 CFR
26.4(f) related to the FFD program for
construction for a limited number of
individuals who construct or direct the
construction of safety- or securityrelated SSCs.

COMMISSION
[Docket No. 50–412]
FirstEnergy Nuclear Operating
Company
Beaver Valley Power Station, Unit 2
Exemption
jbell on DSK3GLQ082PROD with NOTICES
I. Background.
FirstEnergy Nuclear Operating
Company (FENOC or the licensee) is the
holder of Renewed Facility Operating
License No. NPF-73, which authorizes
operation of Beaver Valley Power
Station, Unit 2 (Beaver Valley 2). The
license provides, among other things,
that Beaver Valley 2 is subject to all
rules, regulations, and orders of the U.S.
Nuclear Regulatory Commission (NRC
or the Commission) now or hereafter in
effect. The facility consists of two
pressurized-water reactors located in
Shippingport, Pennsylvania; however,
this exemption is applicable only to
Beaver Valley 2.
II. Request/Action.
Appendix H, ‘‘Reactor Vessel Material
Surveillance Program Requirements,’’ to
Title 10 of the Code of Federal
Regulations (10 CFR), Part 50, requires
that licensees of commercial light-water
nuclear power reactors with a peak
neutron fluence exceeding 1x1017
neutrons per centimeter-squared (n/
cm2) (with energy greater than 1 million
electron volts (E > 1 MeV)) at the end
of the reactor vessel design life maintain
a reactor vessel material surveillance
program that tests irradiated material
specimens that are located in
surveillance capsules in the reactor
vessel. Beaver Valley 2 is subject to
these requirements, and therefore,
maintains a reactor vessel surveillance
program in accordance with Appendix
H to 10 CFR part 50. Section IV.A of
Appendix H to 10 CFR part 50 requires
that each surveillance specimen capsule
withdrawal and associated test results
must be the subject of a summary
technical report that is to be submitted
to the NRC within 1 year of the date of
the capsule withdrawal.
By letter dated, December 18, 2018,
FENOC requested an exemption to the
requirements of Section IV.A of
Appendix H to 10 CFR part 50 for
Beaver Valley 2. Specifically, FENOC
requested an exemption from the
Appendix H testing and report submittal
VerDate Sep<11>2014
17:00 Jun 11, 2019
Jkt 247001
requirements for Capsule Y, which
FENOC removed from the Beaver Valley
2 reactor vessel on October 29, 2018.
The licensee stated that Capsule Y will
be disassembled, and the neutron
dosimeters will be tested within 1 year
after the capsule withdrawal to ensure
that valid dosimetry measurements can
be obtained prior to excessive
radioactive decay of the dosimeters. The
capsule contents will be inventoried
and placed in storage so that they are
retrievable for future testing if it
becomes necessary. Mechanical testing
of Capsule Y will not be performed.
FENOC is requesting this exemption
because Beaver Valley 2 will cease
power operation by October 31, 2021.
FENOC informed the NRC of this by
letter dated April 25, 2018. While the
Beaver Valley 2 Renewed Facility
Operating License expires on May 27,
2047, the original 40-year license was to
expire on May 27, 2027. The previous
capsule withdrawal testing and reports
justify operation of the reactor vessel
through the end of the original 40-year
license. Capsule Y was required to
justify operation to the end of the
renewed 60-year license. If a decision is
made to operate Beaver Valley 2 beyond
October 31, 2021, FENOC stated that a
revised capsule testing schedule would
be submitted for NRC approval prior to
October 31, 2021.
III. Discussion.
Pursuant to 10 CFR 50.12, the
Commission may, upon application by
any interested person or upon its own
initiative, grant exemptions from the
requirements of 10 CFR part 50, when
(1) the exemptions are authorized by
law, will not present an undue risk to
public health or safety, and are
consistent with the common defense
and security; and (2) when special
circumstances are present.
A. The Exemption is Authorized by
Law.
This exemption would exempt Beaver
Valley 2 from the Section IV.A of
Appendix H to 10 CFR part 50 required
testing and the submittal of a summary
technical report (regarding capsule
withdrawal and capsule test results) for
reactor vessel Capsule Y to the NRC
within 1 year of the capsule withdrawal
for Beaver Valley 2.
As stated above, 10 CFR 50.12 allows
the NRC to grant exemptions from the
requirements of 10 CFR part 50. The
NRC staff has determined that granting
of the licensee’s proposed exemption
will not result in a violation of the
Atomic Energy Act of 1954, as amended,
or the Commission’s regulations.
PO 00000
Frm 00138
Fmt 4703
Sfmt 4703
Therefore, the exemption is authorized
by law.
B. The Exemption Presents No Undue
Risk to Public Health and Safety.
The underlying purpose of Appendix
H to 10 CFR part 50 is to monitor
changes in the fracture toughness
properties of ferritic materials in the
reactor vessel beltline region of
light-water nuclear power reactors
which result from exposure of these
materials to neutron irradiation and the
thermal environment. This fracture
toughness test data obtained from the
material surveillance program is
subsequently used to assess the integrity
of the reactor vessel, as described in 10
CFR 50.61, ‘‘Fracture Toughness
Requirements for Protection Against
Pressurized Thermal Shock Events,’’
and Appendix G, ‘‘Fracture Toughness
Requirements,’’ to 10 CFR part 50. As
such, the fracture toughness data
obtained by the Appendix H material
surveillance program serves the
underlying purposes of 10 CFR 50.61
and Appendix G to 10 CFR part 50.
The underlying purpose of 10 CFR
50.61 is to prevent potential failure of
the reactor vessel as a result of
postulated pressurized thermal shock
(PTS) events (transients in
pressurized-water reactors causing
severe overcooling concurrent with or
followed by significant pressure in the
reactor vessel). The underlying purpose
of Appendix G to 10 CFR part 50 is to
provide an acceptable margin of safety
against brittle failure of the reactor
coolant system (RCS) during any
condition of normal operation to which
the pressure boundary may be subjected
over its service lifetime.
Appendix H to 10 CFR Part 50
Appendix H to 10 CFR part 50
requires, in part, that the design of the
surveillance program and the
withdrawal schedule meet the
requirements of American Society for
Testing and Materials (ASTM) E185,
‘‘Standard Recommended Practice for
Conducting Surveillance Tests for LightWater Cooled Reactor Vessels.’’ Prior to
receiving a renewed operating license
on November 5, 2009, the Beaver Valley
2 operating license was scheduled to
expire at midnight May 27, 2027 (i.e.,
the end of the original 40-year operating
license). By letter dated April 25, 2018,
FENOC informed the NRC that Beaver
Valley 2 plans to cease operation by
October 31, 2021, which is prior to the
expiration of the original 40-year
operating license.
As of January 2019, Beaver Valley 2
has withdrawn and tested a total of four
surveillance capsules (i.e., Capsules U,
E:\FR\FM\12JNN1.SGM

V, W, and X). The test results from the
latest surveillance capsule (i.e., Capsule
X) are documented in WCAP-16527-NP,
Revision 0, ‘‘Analysis of Capsule X from
FENOC Nuclear Operating Company
Beaver Valley Unit 2 Reactor Vessel
Radiation Surveillance Program.’’ Per
WCAP-16527-NP, Capsule X received a
neutron fluence of 5.601 × 1019 n/cm2
after an irradiation time of 13.94
effective full power years (EFPY). The
NRC staff notes that the calculated
neutron fluence (E >1.0 MeV) at the core
mid-plane for the Beaver Valley 2
reactor vessel at the end of 40-years of
plant operation (i.e., ∼36 EFPY) is 4.113
× 1019 n/cm2. Consistent with ASTM
E185, the withdrawal of Capsule X for
a 40-year license term was completed at
not less than once or greater than twice
the peak end-of-life vessel fluence (i.e.,
4.113 × 1019 n/cm2). Based on the
review of the capsules that have already
been withdrawn and tested for Beaver
Valley 2, the NRC staff notes that no
additional capsules are required to
satisfy Appendix H to 10 CFR part 50
and ASTM E185 for the original 40-year
license term.
Appendix G to 10 CFR Part 50—Upper
Shelf Energy
Appendix G to 10 CFR part 50
requires that for the reactor vessel
beltline materials, including welds,
plates and forgings, the values of RTNDT
and Charpy upper-shelf energy must
account for the effects of neutron
radiation, including the results of the
surveillance program of Appendix H to
10 CFR part 50. Specifically, Appendix
G to 10 CFR part 50 requires, in part,
that reactor vessel beltline materials
must maintain Charpy upper-shelf
energy (USE) throughout the life of the
vessel of no less than 50 feet/pounds (ftlb) (68 J).
As documented in WCAP-16527,
Supplement 1, Revision 1, the licensee
used the results of the surveillance
Capsule X to determine the USE values
for all of the vessel materials (i.e., all of
the beltline or extended beltline
material) and that at 54 EFPY (i.e.,
beyond the original 40-year operating
license) the USE values for all of the
vessel materials will be maintained at
no less than 50 ft-lb. In NUREG-1929,
Volume 2, ‘‘Safety Evaluation Report
Related to the License Renewal of
Beaver Valley Power Station, Units 1
and 2 (NUREG-1929, Volume 2),’’ the
NRC staff reviewed this assessment and
concluded that the licensee correctly
used applicable surveillance data for
determining that the Beaver Valley 2
reactor vessel beltline materials will
maintain Charpy USE values no less
than 50 ft-lb (68 J) through the 54 EFPY
VerDate Sep<11>2014
18:23 Jun 11, 2019
Jkt 247001
in accordance with Appendix G to 10
CFR part 50. On October 31, 2021, the
date when the licensee certified that it
expects to permanently cease power
operations, Beaver Valley 2 will have
operated about 29.4 EFPY (see WCAP–
17790–NP). As such, the licensee has
demonstrated that the reactor vessel
beltline materials will maintain Charpy
USE values of no less than 50 ft-lb (68
J) throughout the continued plant
operation of Beaver Valley 2 through
October 31, 2021.
Appendix G to 10 CFR Part 50—
Pressure-Temperature Limits
Appendix G to 10 CFR part 50
requires that for the reactor vessel
beltline materials, including welds,
plates and forgings, the values of RTNDT
and Charpy upper-shelf energy must
account for the effects of neutron
radiation, including the results of the
surveillance program of Appendix H to
10 CFR part 50. Specifically, Appendix
G to 10 CFR part 50 requires, in part,
that pressure-temperature (P-T) limits be
established for the reactor coolant
pressure boundary during normal
operating and hydrostatic or leak rate
testing conditions.
By letter dated July 15, 2003, the NRC
staff issued Amendment No. 138 and its
accompanying safety evaluation for
Beaver Valley 2 that permitted the
licensee to relocate the P-T limits from
the technical specifications to a
licensee-controlled document called the
P-T Limits Report (PTLR), consistent
with the guidance in Generic Letter (GL)
96–03, ‘‘Relocation of the Pressure
Temperature Limit Curves and Low
Temperature Overpressure Protections
System Limits.’’ In addition,
administrative controls via Technical
Specification (TS) 6.9.6, ‘‘Reactor
Coolant System (RCS) Pressure and
Temperature Limits Report (PTLR)’’
(currently numbered as TS 5.6.4), were
established, which provide
requirements for the control of future
changes to the plant-specific P-T limits
and for submittal of PTLR revisions to
the NRC.
The latest revision of the Beaver
Valley 2 PTLR indicates that after
considering the results from Capsule X,
the limiting vessel material for the P-T
limits is the intermediate shell plate
B9004-1 at 30 EFPY. Based on the
analysis in WCAP-17790-NP, Revision
1, Enclosure B, ‘‘PWR Vessel Internals
Program Plan for Aging Management of
Reactor Internals at Beaver Valley Power
Station Unit 2,’’ in fall 2021, the time
period in which licensee certified that it
expects to permanently cease power
operations, Beaver Valley 2 will have
operated 29.4 EFPY. The staff
PO 00000
Frm 00139
Fmt 4703
Sfmt 4703
27369
previously found Beaver Valley 2’s
Aging Management program acceptable
by letter dated October 7, 2016. Thus,
the staff finds that the P-T limits in the
licensee’s PTLR will remain applicable
(i.e., through 30 EFPY) beyond the
expected plant operation of Beaver
Valley 2 (i.e., ~29.4 EFPY). However, if
a change to the P-T limits is necessary
before Beaver Valley 2 expects to
permanently cease power operations,
the NRC staff finds that TS 5.6.4
provides the necessary administrative
controls to ensure changes will be
implemented in accordance with
methodology approved in the PTLR,
such that the requirements for P-T limits
in Appendix G to 10 CFR part 50 will
continue to be satisfied.
10 CFR Part 50.61
10 CFR 50.61 requires, in part, that for
each pressurized-water nuclear power
reactor, the licensee shall have projected
values of RTPTS for each reactor vessel
beltline material using the end-of-life
fluence for that material. Specifically,
10 CFR 50.61 establishes PTS screening
criterion of 270 degrees Fahrenheit (°F)
for plates, forgings, and axial weld
materials, and 300 °F for circumferential
weld materials. The regulations in 10
CFR 50.61 also require, in part, that
licensees consider plant-specific
information that could affect the level of
embrittlement, which includes, but is
not limited to, the reactor vessel
operating temperature and any related
surveillance program results.
As documented in WCAP-16527,
Supplement 1, Revision 1, the RTPTS
values were generated for all beltline
and extended beltline region materials
of the Beaver Valley 2 reactor vessel for
fluence values at 54 EFPY, and these
values were based on plant-specific
surveillance program results and have
been included in the PTS evaluation.
The NRC staff also confirmed that the
RTPTS values for all beltline and
extended beltline region materials of the
Beaver Valley 2 reactor vessel for
fluence values at 54 EFPY were less
than the applicable screening criterion
established in 10 CFR 50.61. Further,
the NRC staff previously reviewed this
assessment and concluded that the
licensee accurately calculated the RTPTS
values for all reactor vessel beltline
materials for 54 EFPY and has correctly
used applicable surveillance data for
determining that all Beaver Valley 2
reactor vessel beltline materials will
remain in compliance 10 CFR 50.61
through 54 EFPY (see NUREG-1929,
Volume 2). As such, the licensee has
demonstrated that the RTPTS values for
all beltline and extended beltline region
materials of the Beaver Valley 2 reactor
E:\FR\FM\12JNN1.SGM
12JNN1
27370
Federal Register / Vol. 84, No. 113 / Wednesday, June 12, 2019 / Notices
vessel are less than the applicable
screening criterion established in 10
CFR 50.61 through the continued plant
operation of Beaver Valley 2 (October
31, 2021).
Conclusion
Based on the above, no new accident
precursors are created by the proposed
exemption; thus, the probability of
postulated accidents is not increased.
Also, based on the above, the
consequences of postulated accidents
are not increased. No changes are being
made in the types or amounts of
effluents that may be released offsite.
There is no significant increase in
occupational or public radiation
exposure. Therefore, there is no undue
risk to public health and safety.
C. The Exemption is Consistent with the
Common Defense and Security.
The proposed exemption would
exempt Beaver Valley 2 from the
requirements of Section IV.A to
Appendix H to 10 CFR part 50 for
testing and the submittal of a summary
technical report (regarding capsule
withdrawal and capsule test results) for
reactor vessel Capsule Y to the NRC
within 1 year of the capsule withdrawal
for Beaver Valley 2, which occurred on
October 29, 2018. This change to the
testing and submittal of the summary
technical report for Capsule Y at Beaver
Valley 2 does not affect physical
security measures at Beaver Valley 2
and will not adversely affect the
licensee’s ability to physically secure
the site or protect special nuclear
material. Therefore, the common
defense and security is not impacted by
this exemption.

D. Special Circumstances.
Special circumstances, in accordance
with 10 CFR 50.12(a)(2)(ii), are present
whenever application of the regulation
in the particular circumstances would
not serve the underlying purpose of the
rule or is not necessary to achieve the
underlying purpose of the rule. The
following paragraphs discuss how the
underlying purpose of Appendix H to
10 CFR part 50, 10 CFR 50.61, and
Appendix G to 10 CFR part 50 will be
met under the terms of the proposed
exemption.
Appendix H to 10 CFR Part 50
The underlying purpose of Appendix
H to 10 CFR part 50 is to require
licensees to implement a reactor vessel
materials surveillance program to
monitor changes in the fracture
toughness properties of reactor vessel
materials adjacent to the reactor core. As
such, Appendix H requires, in part, that
VerDate Sep<11>2014
17:00 Jun 11, 2019
Jkt 247001
the design of the surveillance program
and the withdrawal schedule meet the
requirements of ASTM E185. As stated
above, Beaver Valley 2 has withdrawn
and tested a total of four surveillance
capsules (i.e., Capsules U, V, W, and X),
with the test results from the latest
surveillance capsule (i.e., Capsule X)
documented in WCAP-16527-NP,
Revision 0. Based on the review of the
capsules that have already been
withdrawn and tested for Beaver Valley
2, the NRC staff notes that no additional
capsules are required to satisfy
Appendix H to 10 CFR part 50 and
ASTM E185 for the original 40-year
license term.
Since the licensee plans to
permanently cease power operation of
Beaver Valley 2 by October 31, 2021
(i.e., approximately 5.5 years prior to
the end of the original 40-year operating
license), the staff finds that the testing
and submittal of the summary report for
Capsule Y does not serve the underlying
purpose to obtain fracture toughness test
data to monitor changes in the ferritic
materials in the reactor vessel beltline
region for the continued plant operation
of Beaver Valley 2 through October 31,
2021.
Appendix G to 10 CFR Part 50—Upper
Shelf Energy
The underlying purpose of Appendix
G to 10 CFR part 50 is to provide an
acceptable margin of safety against
brittle failure of the RCS during any
condition of normal operation to which
the pressure boundary may be subjected
over its service lifetime. Appendix G to
10 CFR part 50 requires, in part, that
reactor vessel beltline materials must
maintain Charpy USE throughout the
life of the vessel of no less than 50 ftlb (68 J). As stated above, NRC staff
confirmed that the results of
surveillance Capsule X were used in the
determination of the USE values for all
of the reactor vessel materials (i.e., all of
the beltline or extended beltline
material) and that at 54 EFPY (i.e.,
beyond the original 40-year operating
license), the USE values for all of the
vessel materials will meet Appendix G
to 10 CFR part 50 requirements.
Since the licensee plans to
permanently cease power operation of
Beaver Valley 2 by October 31, 2021
(i.e., approximately 5.5 years prior to
the end of the original 40-year operating
license), the NRC staff finds that the
testing and submittal of the summary
report for Capsule Y does not serve the
underlying purpose to provide an
acceptable margin of safety against
brittle failure of the RCS during any
condition of normal operation as it
relates to Charpy USE for continued
PO 00000

plant operation of Beaver Valley 2
through October 31, 2021.
Appendix G to 10 CFR Part 50—
Pressure-Temperature Limits
The underlying purpose of Appendix
G to 10 CFR part 50 is to provide an
acceptable margin of safety against
brittle failure of the RCS during any
condition of normal operation to which
the pressure boundary may be subjected
over its service lifetime. Appendix G to
10 CFR part 50 requires, in part, that PT limits be established for the reactor
coolant pressure boundary during
normal operating and hydrostatic or
leak rate testing conditions. As stated
above, the NRC staff finds that the P-T
limits in the licensee’s PTLR will
remain applicable (i.e., through 30
EFPY) beyond the expected plant
operation of Beaver Valley 2 (i.e., ∼29.4
EFPY). However, if a change to the P-T
limits is necessary prior to the expected
date in which Beaver Valley 2 ceases
operation, the NRC staff identified that
TS 5.6.4 provides the necessary
administrative controls to ensure
changes will be implemented in
accordance with methodology approved
in the PTLR such that the requirements
for P-T limits in Appendix G to 10 CFR
part 50 will continue to be satisfied.
Since the licensee plans to
permanently cease power operation of
Beaver Valley 2 by October 31, 2021
(i.e., approximately 5.5 years prior to
the end of the original 40-year operating
license), the NRC staff finds that the
testing and submittal of the summary
report for Capsule Y do not serve the
underlying purpose to provide an
acceptable margin of safety against
brittle failure of the RCS during any
condition of normal operation as it
relates to P-T limits for the continued
plant operation of Beaver Valley 2
through October 31, 2021.
10 CFR Part 50.61
The regulations in 10 CFR 50.61
require, in part, that for each
pressurized-water nuclear power
reactor, the licensee shall have projected
values of RTPTS for each reactor vessel
beltline material using the end-of-life
fluence for that material. As stated
above, the licensee has demonstrated
that the RTPTS values for all beltline and
extended beltline region materials of the
Beaver Valley 2 reactor vessel are less
than the applicable screening criterion
established in 10 CFR 50.61 through the
continued plant operation of Beaver
Valley 2 (October 31, 2021).
Since the licensee plans to
permanently cease power operation of
Beaver Valley 2 by October 31, 2021
(i.e., approximately 5.5 years prior to
E:\FR\FM\12JNN1.SGM
12JNN1
Federal Register / Vol. 84, No. 113 / Wednesday, June 12, 2019 / Notices
the end of the original 40-year operating
license), the NRC staff finds that the
testing and submittal of the summary
report for Capsule Y does not serve the
underlying purpose to prevent potential
failure of the reactor vessel as a result
of postulated PTS events for the
continued plant operation of Beaver
Valley 2 through October 31, 2021.
Conclusion
Based on the above, the NRC staff
concludes that the underlying purpose
of Appendix H to 10 CFR part 50 and
its function to provide fracture
toughness data for the evaluations
required by Appendix G to 10 CFR part
50 and 10 CFR 50.61 have been
achieved for the original 40-year license
period of Beaver Valley 2, which will
permanently cease operation by October
31, 2021 (i.e., prior to the end of the
original 40-year license period).
E. Environmental Considerations.
The NRC staff has determined that the
proposed exemption meets the
eligibility criteria for categorical
exclusion set forth in 10 CFR
51.22(c)(25). Therefore, in accordance
with 10 CFR 51.22(b), no environmental
impact statement or environmental
assessment need be prepared in
connection with the proposed issuance
of this exemption request. The basis for
the NRC staff’s determination is
discussed below with an evaluation
against each of the requirements in 10
CFR 51.22(c)(25).
jbell on DSK3GLQ082PROD with NOTICES
Requirements in 10 CFR 51.22(c)(25)(i)
An evaluation of the issue of no
significant hazards consideration, as
provided by the licensee, is presented
below:
1. Does the proposed exemption involve a
significant increase in the probability or
consequence of an accident previously
evaluated?
Response: No
The proposed exemption has no effect on
facility structures, systems, and components
(SSCs), the capability of any facility SSC to
perform its design function, or plant
operations, and, therefore, would not
increase the likelihood of a malfunction of
any facility SSC or increase the consequences
of previously evaluated accidents. The
proposed exemption does not alter any
assumptions or methodology associated with
the previously evaluated accidents in the
BVPS [Beaver Valley Power Station] Updated
Final Safety Analysis Report. The proposed
exemption will not affect the probability of
occurrence of any previously analyzed
accident.
VerDate Sep<11>2014
17:00 Jun 11, 2019
Jkt 247001
Therefore, there is no increase in the
probability or consequence of any previously
evaluated accident.
2. Does the proposed exemption create the
possibility of a new or different kind of
accident from any accident previously
evaluated?
Response: No
The proposed exemption does not involve
a physical alteration of the facility. No new
or different type of equipment will be
installed, and there are no physical
modifications to existing equipment
associated with the proposed exemption.
Similarly, the proposed exemption would
not physically alter any SSCs involved in the
mitigation of any accidents. Thus, no new
initiators or precursors of a new or different
kind of accident are created. Furthermore,
the proposed exemption does not create the
possibility of a new accident as a result of
new failure modes associated with any
equipment or personnel failures. No changes
are being made to the facilities’ normal
parameters or in protective or mitigative
action setpoints, and no new failure modes
are being introduced.
Therefore, the proposed exemption does
not create the possibility of a new or different
kind of accident from any accident
previously evaluated.
3. Does the proposed exemption involve a
significant reduction in a margin of safety?
Response: No
The proposed exemption does not alter the
design basis or any safety limits for BVPS–
2, nor does it impact station operation or any
facility SSC that is relied upon for accident
mitigation.
Therefore, the proposed exemption does
not involve a significant reduction in a
margin of safety.
The NRC staff evaluated the issue of
no significant hazards consideration
using the standards described in 10 CFR
50.92(c). Based on the above evaluation,
the NRC staff has determined that the
three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff
concludes that the proposed exemption
involves no significant hazards
consideration, and the requirements of
10 CFR 51.22(c)(9)(i) are met.
Requirements in 10 CFR 51.22(c)(25)(ii)
through (v)
The proposed exemption from testing
and the associated report submittal
activities for the Beaver Valley 2 reactor
vessel Capsule Y does not involve any
physical plant modifications and would
not alter operation of any plant systems.
As such, the NRC staff concludes that
granting the proposed exemption: (1)
would not result in a significant change
in the types or significant increase in
the amounts of any effluents that may be
PO 00000
Frm 00141
Fmt 4703
Sfmt 4703

released offsite (i.e., satisfies the
provisions of 10 CFR 51.22(c)(25)(ii));
(2) would not result in a significant
increase in individual or cumulative
public or occupational radiation
exposure (i.e., satisfies the provisions of
10 CFR 51.22(c)(25)(iii)); (3) would have
no significant construction impact (i.e.,
satisfies the provisions of 10 CFR
51.22(c)(25)(iv)); and (4) would not
result in a significant increase in the
potential for or consequences from a
radiological accident (i.e., satisfies the
provisions of 10 CFR 51.22(c)(25)(v)).
Requirements in 10 CFR 51.22(c)(25)(i)
The proposed exemption involves the
testing and reporting requirements of
the Beaver Valley 2 reactor vessel
surveillance program. Performance of
the scheduled capsule testing is a
surveillance requirement, therefore
satisfying the provisions of 10 CFR
51.22(c)(25)(vi)(C).
Conclusion
Based on the above, the NRC staff
concludes that the proposed exemption
meets the eligibility criteria for
categorical exclusion set forth in 10 CFR
51.22(c)(25)(i) through (vi). Therefore,
pursuant to 10 CFR 51.22(b), no
environmental impact statement or
environmental assessment is required to
be prepared in connection with the
proposed issuance of the exemption.
IV. Conclusion
Accordingly, the Commission has
determined that, pursuant to 10 CFR
50.12, the exemption is authorized by
law, will not present an undue risk to
the public health and safety, and is
consistent with the common defense
and security. Also, special
circumstances are present. Therefore,
the Commission hereby grants FENOC a
permanent exemption from Section IV.A
of Appendix H to 10 CFR part 50 for
testing and the submittal of a summary
technical report (regarding capsule
withdrawal and capsule test results) for
reactor vessel Capsule Y to the NRC
within 1 year of the capsule withdrawal
for Beaver Valley 2.

ATTACHMENT--Exemption
NUCLEAR REGULATORY COMMISSION
[Docket No. 50-412]
FirstEnergy Nuclear Operating Company
Beaver Valley Power Station, Unit 2
Exemption
I. Background.
FirstEnergy Nuclear Operating Company (FENOC or the licensee) is
the holder of Renewed Facility Operating License No. NPF-73, which
authorizes operation of Beaver Valley Power Station, Unit 2 (Beaver
Valley 2). The license provides, among other things, that Beaver Valley
2 is subject to all rules, regulations, and orders of the U.S. Nuclear
Regulatory Commission (NRC or the Commission) now or hereafter in
effect. The facility consists of two pressurized-water reactors located
in Shippingport, Pennsylvania; however, this exemption is applicable
only to Beaver Valley 2.
II. Request/Action.
Appendix H, ``Reactor Vessel Material Surveillance Program
Requirements,'' to Title 10 of the Code of Federal Regulations (10
CFR), Part 50, requires that licensees of commercial light-water
nuclear power reactors with a peak neutron fluence exceeding 1x10\17\
neutrons per centimeter-squared (n/cm\2\) (with energy greater than 1
million electron volts (E > 1 MeV)) at the end of the reactor vessel
design life maintain a reactor vessel material surveillance program
that tests irradiated material specimens that are located in
surveillance capsules in the reactor vessel. Beaver Valley 2 is subject
to these requirements, and therefore, maintains a reactor vessel
surveillance program in accordance with Appendix H to 10 CFR part 50.
Section IV.A of Appendix H to 10 CFR part 50 requires that each
surveillance specimen capsule withdrawal and associated test results
must be the subject of a summary technical report that is to be
submitted to the NRC within 1 year of the date of the capsule
withdrawal.
By letter dated, December 18, 2018, FENOC requested an exemption to
the requirements of Section IV.A of Appendix H to 10 CFR part 50 for
Beaver Valley 2. Specifically, FENOC requested an exemption from the
Appendix H testing and report submittal requirements for Capsule Y,
which FENOC removed from the Beaver Valley 2 reactor vessel on October
29, 2018. The licensee stated that Capsule Y will be disassembled, and
the neutron dosimeters will be tested within 1 year after the capsule
withdrawal to ensure that valid dosimetry measurements can be obtained
prior to excessive radioactive decay of the dosimeters. The capsule
contents will be inventoried and placed in storage so that they are
retrievable for future testing if it becomes necessary. Mechanical
testing of Capsule Y will not be performed.
FENOC is requesting this exemption because Beaver Valley 2 will
cease power operation by October 31, 2021. FENOC informed the NRC of
this by letter dated April 25, 2018. While the Beaver Valley 2 Renewed
Facility Operating License expires on May 27, 2047, the original 40-
year license was to expire on May 27, 2027. The previous capsule
withdrawal testing and reports justify operation of the reactor vessel
through the end of the original 40-year license. Capsule Y was required
to justify operation to the end of the renewed 60-year license. If a
decision is made to operate Beaver Valley 2 beyond October 31, 2021,
FENOC stated that a revised capsule testing schedule would be submitted
for NRC approval prior to October 31, 2021.
III. Discussion.
Pursuant to 10 CFR 50.12, the Commission may, upon application by
any interested person or upon its own initiative, grant exemptions from
the requirements of 10 CFR part 50, when (1) the exemptions are
authorized by law, will not present an undue risk to public health or
safety, and are consistent with the common defense and security; and
(2) when special circumstances are present.
A. The Exemption is Authorized by Law.
This exemption would exempt Beaver Valley 2 from the Section IV.A
of Appendix H to 10 CFR part 50 required testing and the submittal of a
summary technical report (regarding capsule withdrawal and capsule test
results) for reactor vessel Capsule Y to the NRC within 1 year of the
capsule withdrawal for Beaver Valley 2.
As stated above, 10 CFR 50.12 allows the NRC to grant exemptions
from the requirements of 10 CFR part 50. The NRC staff has determined
that granting of the licensee's proposed exemption will not result in a
violation of the Atomic Energy Act of 1954, as amended, or the
Commission's regulations. Therefore, the exemption is authorized by
law.
B. The Exemption Presents No Undue Risk to Public Health and Safety.
The underlying purpose of Appendix H to 10 CFR part 50 is to
monitor changes in the fracture toughness properties of ferritic
materials in the reactor vessel beltline region of light[dash]water
nuclear power reactors which result from exposure of these materials to
neutron irradiation and the thermal environment. This fracture
toughness test data obtained from the material surveillance program is
subsequently used to assess the integrity of the reactor vessel, as
described in 10 CFR 50.61, ``Fracture Toughness Requirements for
Protection Against Pressurized Thermal Shock Events,'' and Appendix G,
``Fracture Toughness Requirements,'' to 10 CFR part 50. As such, the
fracture toughness data obtained by the Appendix H material
surveillance program serves the underlying purposes of 10 CFR 50.61 and
Appendix G to 10 CFR part 50.
The underlying purpose of 10 CFR 50.61 is to prevent potential
failure of the reactor vessel as a result of postulated pressurized
thermal shock (PTS) events (transients in pressurized[dash]water
reactors causing severe overcooling concurrent with or followed by
significant pressure in the reactor vessel). The underlying purpose of
Appendix G to 10 CFR part 50 is to provide an acceptable margin of
safety against brittle failure of the reactor coolant system (RCS)
during any condition of normal operation to which the pressure boundary
may be subjected over its service lifetime.
Appendix H to 10 CFR Part 50
Appendix H to 10 CFR part 50 requires, in part, that the design of
the surveillance program and the withdrawal schedule meet the
requirements of American Society for Testing and Materials (ASTM) E185,
``Standard Recommended Practice for Conducting Surveillance Tests for
Light-Water Cooled Reactor Vessels.'' Prior to receiving a renewed
operating license on November 5, 2009, the Beaver Valley 2 operating
license was scheduled to expire at midnight May 27, 2027 (i.e., the end
of the original 40-year operating license). By letter dated April 25,
2018, FENOC informed the NRC that Beaver Valley 2 plans to cease
operation by October 31, 2021, which is prior to the expiration of the
original 40-year operating license.
As of January 2019, Beaver Valley 2 has withdrawn and tested a
total of four surveillance capsules (i.e., Capsules U,
[[Page 27369]]
V, W, and X). The test results from the latest surveillance capsule
(i.e., Capsule X) are documented in WCAP-16527-NP, Revision 0,
``Analysis of Capsule X from FENOC Nuclear Operating Company Beaver
Valley Unit 2 Reactor Vessel Radiation Surveillance Program.'' Per
WCAP-16527-NP, Capsule X received a neutron fluence of 5.601 x 10\19\
n/cm\2\ after an irradiation time of 13.94 effective full power years
(EFPY). The NRC staff notes that the calculated neutron fluence (E >1.0
MeV) at the core mid-plane for the Beaver Valley 2 reactor vessel at
the end of 40-years of plant operation (i.e., ~36 EFPY) is 4.113 x
10\19\ n/cm\2\. Consistent with ASTM E185, the withdrawal of Capsule X
for a 40-year license term was completed at not less than once or
greater than twice the peak end-of-life vessel fluence (i.e., 4.113 x
10\19\ n/cm\2\). Based on the review of the capsules that have already
been withdrawn and tested for Beaver Valley 2, the NRC staff notes that
no additional capsules are required to satisfy Appendix H to 10 CFR
part 50 and ASTM E185 for the original 40-year license term.
Appendix G to 10 CFR Part 50--Upper Shelf Energy
Appendix G to 10 CFR part 50 requires that for the reactor vessel
beltline materials, including welds, plates and forgings, the values of
RTNDT and Charpy upper-shelf energy must account for the
effects of neutron radiation, including the results of the surveillance
program of Appendix H to 10 CFR part 50. Specifically, Appendix G to 10
CFR part 50 requires, in part, that reactor vessel beltline materials
must maintain Charpy upper-shelf energy (USE) throughout the life of
the vessel of no less than 50 feet/pounds (ft-lb) (68 J).
As documented in WCAP-16527, Supplement 1, Revision 1, the licensee
used the results of the surveillance Capsule X to determine the USE
values for all of the vessel materials (i.e., all of the beltline or
extended beltline material) and that at 54 EFPY (i.e., beyond the
original 40-year operating license) the USE values for all of the
vessel materials will be maintained at no less than 50 ft-lb. In NUREG-
1929, Volume 2, ``Safety Evaluation Report Related to the License
Renewal of Beaver Valley Power Station, Units 1 and 2 (NUREG-1929,
Volume 2),'' the NRC staff reviewed this assessment and concluded that
the licensee correctly used applicable surveillance data for
determining that the Beaver Valley 2 reactor vessel beltline materials
will maintain Charpy USE values no less than 50 ft-lb (68 J) through
the 54 EFPY in accordance with Appendix G to 10 CFR part 50. On October
31, 2021, the date when the licensee certified that it expects to
permanently cease power operations, Beaver Valley 2 will have operated
about 29.4 EFPY (see WCAP-17790-NP). As such, the licensee has
demonstrated that the reactor vessel beltline materials will maintain
Charpy USE values of no less than 50 ft-lb (68 J) throughout the
continued plant operation of Beaver Valley 2 through October 31, 2021.
Appendix G to 10 CFR Part 50--Pressure-Temperature Limits
Appendix G to 10 CFR part 50 requires that for the reactor vessel
beltline materials, including welds, plates and forgings, the values of
RTNDT and Charpy upper-shelf energy must account for the
effects of neutron radiation, including the results of the surveillance
program of Appendix H to 10 CFR part 50. Specifically, Appendix G to 10
CFR part 50 requires, in part, that pressure-temperature (P-T) limits
be established for the reactor coolant pressure boundary during normal
operating and hydrostatic or leak rate testing conditions.
By letter dated July 15, 2003, the NRC staff issued Amendment No.
138 and its accompanying safety evaluation for Beaver Valley 2 that
permitted the licensee to relocate the P-T limits from the technical
specifications to a licensee-controlled document called the P-T Limits
Report (PTLR), consistent with the guidance in Generic Letter (GL) 96-
03, ``Relocation of the Pressure Temperature Limit Curves and Low
Temperature Overpressure Protections System Limits.'' In addition,
administrative controls via Technical Specification (TS) 6.9.6,
``Reactor Coolant System (RCS) Pressure and Temperature Limits Report
(PTLR)'' (currently numbered as TS 5.6.4), were established, which
provide requirements for the control of future changes to the plant-
specific P-T limits and for submittal of PTLR revisions to the NRC.
The latest revision of the Beaver Valley 2 PTLR indicates that
after considering the results from Capsule X, the limiting vessel
material for the P-T limits is the intermediate shell plate B9004-1 at
30 EFPY. Based on the analysis in WCAP-17790-NP, Revision 1, Enclosure
B, ``PWR Vessel Internals Program Plan for Aging Management of Reactor
Internals at Beaver Valley Power Station Unit 2,'' in fall 2021, the
time period in which licensee certified that it expects to permanently
cease power operations, Beaver Valley 2 will have operated 29.4 EFPY.
The staff previously found Beaver Valley 2's Aging Management program
acceptable by letter dated October 7, 2016. Thus, the staff finds that
the P-T limits in the licensee's PTLR will remain applicable (i.e.,
through 30 EFPY) beyond the expected plant operation of Beaver Valley 2
(i.e., ~29.4 EFPY). However, if a change to the P-T limits is necessary
before Beaver Valley 2 expects to permanently cease power operations,
the NRC staff finds that TS 5.6.4 provides the necessary administrative
controls to ensure changes will be implemented in accordance with
methodology approved in the PTLR, such that the requirements for P-T
limits in Appendix G to 10 CFR part 50 will continue to be satisfied.
10 CFR Part 50.61
10 CFR 50.61 requires, in part, that for each pressurized-water
nuclear power reactor, the licensee shall have projected values of
RTPTS for each reactor vessel beltline material using the
end-of-life fluence for that material. Specifically, 10 CFR 50.61
establishes PTS screening criterion of 270 degrees Fahrenheit ([deg]F)
for plates, forgings, and axial weld materials, and 300 [deg]F for
circumferential weld materials. The regulations in 10 CFR 50.61 also
require, in part, that licensees consider plant-specific information
that could affect the level of embrittlement, which includes, but is
not limited to, the reactor vessel operating temperature and any
related surveillance program results.
As documented in WCAP-16527, Supplement 1, Revision 1, the
RTPTS values were generated for all beltline and extended
beltline region materials of the Beaver Valley 2 reactor vessel for
fluence values at 54 EFPY, and these values were based on plant-
specific surveillance program results and have been included in the PTS
evaluation. The NRC staff also confirmed that the RTPTS
values for all beltline and extended beltline region materials of the
Beaver Valley 2 reactor vessel for fluence values at 54 EFPY were less
than the applicable screening criterion established in 10 CFR 50.61.
Further, the NRC staff previously reviewed this assessment and
concluded that the licensee accurately calculated the RTPTS
values for all reactor vessel beltline materials for 54 EFPY and has
correctly used applicable surveillance data for determining that all
Beaver Valley 2 reactor vessel beltline materials will remain in
compliance 10 CFR 50.61 through 54 EFPY (see NUREG-1929, Volume 2). As
such, the licensee has demonstrated that the RTPTS values
for all beltline and extended beltline region materials of the Beaver
Valley 2 reactor
[[Page 27370]]
vessel are less than the applicable screening criterion established in
10 CFR 50.61 through the continued plant operation of Beaver Valley 2
(October 31, 2021).
Conclusion
Based on the above, no new accident precursors are created by the
proposed exemption; thus, the probability of postulated accidents is
not increased. Also, based on the above, the consequences of postulated
accidents are not increased. No changes are being made in the types or
amounts of effluents that may be released offsite. There is no
significant increase in occupational or public radiation exposure.
Therefore, there is no undue risk to public health and safety.
C. The Exemption is Consistent with the Common Defense and Security.
The proposed exemption would exempt Beaver Valley 2 from the
requirements of Section IV.A to Appendix H to 10 CFR part 50 for
testing and the submittal of a summary technical report (regarding
capsule withdrawal and capsule test results) for reactor vessel Capsule
Y to the NRC within 1 year of the capsule withdrawal for Beaver Valley
2, which occurred on October 29, 2018. This change to the testing and
submittal of the summary technical report for Capsule Y at Beaver
Valley 2 does not affect physical security measures at Beaver Valley 2
and will not adversely affect the licensee's ability to physically
secure the site or protect special nuclear material. Therefore, the
common defense and security is not impacted by this exemption.
D. Special Circumstances.
Special circumstances, in accordance with 10 CFR 50.12(a)(2)(ii),
are present whenever application of the regulation in the particular
circumstances would not serve the underlying purpose of the rule or is
not necessary to achieve the underlying purpose of the rule. The
following paragraphs discuss how the underlying purpose of Appendix H
to 10 CFR part 50, 10 CFR 50.61, and Appendix G to 10 CFR part 50 will
be met under the terms of the proposed exemption.
Appendix H to 10 CFR Part 50
The underlying purpose of Appendix H to 10 CFR part 50 is to
require licensees to implement a reactor vessel materials surveillance
program to monitor changes in the fracture toughness properties of
reactor vessel materials adjacent to the reactor core. As such,
Appendix H requires, in part, that the design of the surveillance
program and the withdrawal schedule meet the requirements of ASTM E185.
As stated above, Beaver Valley 2 has withdrawn and tested a total of
four surveillance capsules (i.e., Capsules U, V, W, and X), with the
test results from the latest surveillance capsule (i.e., Capsule X)
documented in WCAP-16527-NP, Revision 0. Based on the review of the
capsules that have already been withdrawn and tested for Beaver Valley
2, the NRC staff notes that no additional capsules are required to
satisfy Appendix H to 10 CFR part 50 and ASTM E185 for the original 40-
year license term.
Since the licensee plans to permanently cease power operation of
Beaver Valley 2 by October 31, 2021 (i.e., approximately 5.5 years
prior to the end of the original 40-year operating license), the staff
finds that the testing and submittal of the summary report for Capsule
Y does not serve the underlying purpose to obtain fracture toughness
test data to monitor changes in the ferritic materials in the reactor
vessel beltline region for the continued plant operation of Beaver
Valley 2 through October 31, 2021.
Appendix G to 10 CFR Part 50--Upper Shelf Energy
The underlying purpose of Appendix G to 10 CFR part 50 is to
provide an acceptable margin of safety against brittle failure of the
RCS during any condition of normal operation to which the pressure
boundary may be subjected over its service lifetime. Appendix G to 10
CFR part 50 requires, in part, that reactor vessel beltline materials
must maintain Charpy USE throughout the life of the vessel of no less
than 50 ft-lb (68 J). As stated above, NRC staff confirmed that the
results of surveillance Capsule X were used in the determination of the
USE values for all of the reactor vessel materials (i.e., all of the
beltline or extended beltline material) and that at 54 EFPY (i.e.,
beyond the original 40-year operating license), the USE values for all
of the vessel materials will meet Appendix G to 10 CFR part 50
requirements.
Since the licensee plans to permanently cease power operation of
Beaver Valley 2 by October 31, 2021 (i.e., approximately 5.5 years
prior to the end of the original 40-year operating license), the NRC
staff finds that the testing and submittal of the summary report for
Capsule Y does not serve the underlying purpose to provide an
acceptable margin of safety against brittle failure of the RCS during
any condition of normal operation as it relates to Charpy USE for
continued plant operation of Beaver Valley 2 through October 31, 2021.
Appendix G to 10 CFR Part 50--Pressure-Temperature Limits
The underlying purpose of Appendix G to 10 CFR part 50 is to
provide an acceptable margin of safety against brittle failure of the
RCS during any condition of normal operation to which the pressure
boundary may be subjected over its service lifetime. Appendix G to 10
CFR part 50 requires, in part, that P-T limits be established for the
reactor coolant pressure boundary during normal operating and
hydrostatic or leak rate testing conditions. As stated above, the NRC
staff finds that the P-T limits in the licensee's PTLR will remain
applicable (i.e., through 30 EFPY) beyond the expected plant operation
of Beaver Valley 2 (i.e., ~29.4 EFPY). However, if a change to the P-T
limits is necessary prior to the expected date in which Beaver Valley 2
ceases operation, the NRC staff identified that TS 5.6.4 provides the
necessary administrative controls to ensure changes will be implemented
in accordance with methodology approved in the PTLR such that the
requirements for P-T limits in Appendix G to 10 CFR part 50 will
continue to be satisfied.
Since the licensee plans to permanently cease power operation of
Beaver Valley 2 by October 31, 2021 (i.e., approximately 5.5 years
prior to the end of the original 40-year operating license), the NRC
staff finds that the testing and submittal of the summary report for
Capsule Y do not serve the underlying purpose to provide an acceptable
margin of safety against brittle failure of the RCS during any
condition of normal operation as it relates to P-T limits for the
continued plant operation of Beaver Valley 2 through October 31, 2021.
10 CFR Part 50.61
The regulations in 10 CFR 50.61 require, in part, that for each
pressurized-water nuclear power reactor, the licensee shall have
projected values of RTPTS for each reactor vessel beltline
material using the end-of-life fluence for that material. As stated
above, the licensee has demonstrated that the RTPTS values
for all beltline and extended beltline region materials of the Beaver
Valley 2 reactor vessel are less than the applicable screening
criterion established in 10 CFR 50.61 through the continued plant
operation of Beaver Valley 2 (October 31, 2021).
Since the licensee plans to permanently cease power operation of
Beaver Valley 2 by October 31, 2021 (i.e., approximately 5.5 years
prior to
[[Page 27371]]
the end of the original 40-year operating license), the NRC staff finds
that the testing and submittal of the summary report for Capsule Y does
not serve the underlying purpose to prevent potential failure of the
reactor vessel as a result of postulated PTS events for the continued
plant operation of Beaver Valley 2 through October 31, 2021.
Conclusion
Based on the above, the NRC staff concludes that the underlying
purpose of Appendix H to 10 CFR part 50 and its function to provide
fracture toughness data for the evaluations required by Appendix G to
10 CFR part 50 and 10 CFR 50.61 have been achieved for the original 40-
year license period of Beaver Valley 2, which will permanently cease
operation by October 31, 2021 (i.e., prior to the end of the original
40-year license period).
E. Environmental Considerations.
The NRC staff has determined that the proposed exemption meets the
eligibility criteria for categorical exclusion set forth in 10 CFR
51.22(c)(25). Therefore, in accordance with 10 CFR 51.22(b), no
environmental impact statement or environmental assessment need be
prepared in connection with the proposed issuance of this exemption
request. The basis for the NRC staff's determination is discussed below
with an evaluation against each of the requirements in 10 CFR
51.22(c)(25).
Requirements in 10 CFR 51.22(c)(25)(i)
An evaluation of the issue of no significant hazards consideration,
as provided by the licensee, is presented below:
1. Does the proposed exemption involve a significant increase in
the probability or consequence of an accident previously evaluated?
Response: No
The proposed exemption has no effect on facility structures,
systems, and components (SSCs), the capability of any facility SSC
to perform its design function, or plant operations, and, therefore,
would not increase the likelihood of a malfunction of any facility
SSC or increase the consequences of previously evaluated accidents.
The proposed exemption does not alter any assumptions or methodology
associated with the previously evaluated accidents in the BVPS
[Beaver Valley Power Station] Updated Final Safety Analysis Report.
The proposed exemption will not affect the probability of occurrence
of any previously analyzed accident.
Therefore, there is no increase in the probability or
consequence of any previously evaluated accident.
2. Does the proposed exemption create the possibility of a new
or different kind of accident from any accident previously
evaluated?
Response: No
The proposed exemption does not involve a physical alteration of
the facility. No new or different type of equipment will be
installed, and there are no physical modifications to existing
equipment associated with the proposed exemption.
Similarly, the proposed exemption would not physically alter any
SSCs involved in the mitigation of any accidents. Thus, no new
initiators or precursors of a new or different kind of accident are
created. Furthermore, the proposed exemption does not create the
possibility of a new accident as a result of new failure modes
associated with any equipment or personnel failures. No changes are
being made to the facilities' normal parameters or in protective or
mitigative action setpoints, and no new failure modes are being
introduced.
Therefore, the proposed exemption does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
3. Does the proposed exemption involve a significant reduction
in a margin of safety?
Response: No
The proposed exemption does not alter the design basis or any
safety limits for BVPS-2, nor does it impact station operation or
any facility SSC that is relied upon for accident mitigation.
Therefore, the proposed exemption does not involve a significant
reduction in a margin of safety.
The NRC staff evaluated the issue of no significant hazards
consideration using the standards described in 10 CFR 50.92(c). Based
on the above evaluation, the NRC staff has determined that the three
standards of 10 CFR 50.92(c) are satisfied. Therefore, the NRC staff
concludes that the proposed exemption involves no significant hazards
consideration, and the requirements of 10 CFR 51.22(c)(9)(i) are met.
Requirements in 10 CFR 51.22(c)(25)(ii) through (v)
The proposed exemption from testing and the associated report
submittal activities for the Beaver Valley 2 reactor vessel Capsule Y
does not involve any physical plant modifications and would not alter
operation of any plant systems. As such, the NRC staff concludes that
granting the proposed exemption: (1) would not result in a significant
change in the types or significant increase in the amounts of any
effluents that may be released offsite (i.e., satisfies the provisions
of 10 CFR 51.22(c)(25)(ii)); (2) would not result in a significant
increase in individual or cumulative public or occupational radiation
exposure (i.e., satisfies the provisions of 10 CFR 51.22(c)(25)(iii));
(3) would have no significant construction impact (i.e., satisfies the
provisions of 10 CFR 51.22(c)(25)(iv)); and (4) would not result in a
significant increase in the potential for or consequences from a
radiological accident (i.e., satisfies the provisions of 10 CFR
51.22(c)(25)(v)).
Requirements in 10 CFR 51.22(c)(25)(i)
The proposed exemption involves the testing and reporting
requirements of the Beaver Valley 2 reactor vessel surveillance
program. Performance of the scheduled capsule testing is a surveillance
requirement, therefore satisfying the provisions of 10 CFR
51.22(c)(25)(vi)(C).
Conclusion
Based on the above, the NRC staff concludes that the proposed
exemption meets the eligibility criteria for categorical exclusion set
forth in 10 CFR 51.22(c)(25)(i) through (vi). Therefore, pursuant to 10
CFR 51.22(b), no environmental impact statement or environmental
assessment is required to be prepared in connection with the proposed
issuance of the exemption.
IV. Conclusion
Accordingly, the Commission has determined that, pursuant to 10 CFR
50.12, the exemption is authorized by law, will not present an undue
risk to the public health and safety, and is consistent with the common
defense and security. Also, special circumstances are present.
Therefore, the Commission hereby grants FENOC a permanent exemption
from Section IV.A of Appendix H to 10 CFR part 50 for testing and the
submittal of a summary technical report (regarding capsule withdrawal
and capsule test results) for reactor vessel Capsule Y to the NRC
within 1 year of the capsule withdrawal for Beaver Valley 2.
