Access to Sensitive Unclassified NonSafeguards Information in This Proceeding
Day
Event/activity
0 ...............
Publication of Federal Register notice of hearing and opportunity to petition for leave to intervene, including order with instructions
for access requests.
Deadline for submitting requests for access to Sensitive Unclassified Non-Safeguards Information (SUNSI) with information: supporting the standing of a potential party identified by name and address; describing the need for the information in order for the
potential party to participate meaningfully in an adjudicatory proceeding.
Deadline for submitting petition for intervention containing: (i) demonstration of standing; (ii) all contentions whose formulation does
not require access to SUNSI (+25 Answers to petition for intervention; +7 requestor/petitioner reply).
Nuclear Regulatory Commission (NRC) staff informs the requestor of the staff’s determination whether the request for access provides a reasonable basis to believe standing can be established and shows need for SUNSI. (NRC staff also informs any party
to the proceeding whose interest independent of the proceeding would be harmed by the release of the information.) If NRC staff
makes the finding of need for SUNSI and likelihood of standing, NRC staff begins document processing (preparation of
redactions or review of redacted documents).
If NRC staff finds no ‘‘need’’ or no likelihood of standing, the deadline for requestor/petitioner to file a motion seeking a ruling to reverse the NRC staff’s denial of access; NRC staff files copy of access determination with the presiding officer (or Chief Administrative Judge or other designated officer, as appropriate). If NRC staff finds ‘‘need’’ for SUNSI, the deadline for any party to the
proceeding whose interest independent of the proceeding would be harmed by the release of the information to file a motion
seeking a ruling to reverse the NRC staff’s grant of access.
Deadline for NRC staff reply to motions to reverse NRC staff determination(s).
(Receipt +30) If NRC staff finds standing and need for SUNSI, deadline for NRC staff to complete information processing and file
motion for Protective Order and draft Non-Disclosure Affidavit. Deadline for applicant/licensee to file Non-Disclosure Agreement
for SUNSI.
If access granted: Issuance of presiding officer or other designated officer decision on motion for protective order for access to sensitive information (including schedule for providing access and submission of contentions) or decision reversing a final adverse
determination by the NRC staff.
Deadline for filing executed Non-Disclosure Affidavits. Access provided to SUNSI consistent with decision issuing the protective
order.
Deadline for submission of contentions whose development depends upon access to SUNSI. However, if more than 25 days remain between the petitioner’s receipt of (or 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.
(Contention receipt +25) Answers to contentions whose development depends upon access to SUNSI.
(Answer receipt +7) Petitioner/Intervenor reply to answers.

SUPPLEMENTARY INFORMATION:
Background Information
The NRC staff developed JLD–ISG–
2012–06 to provide guidance and
clarification to assist nuclear power
reactor licensees, applicants for power
reactor licenses, and holders of
construction permits in active or
deferred status with the performance of
a tsunami, surge, or seiche hazard
assessment.
On March 11, 2011, a magnitude 9.0
earthquake struck off the coast of the
Japanese island of Honshu. The
earthquake resulted in a large tsunami,
estimated to have exceeded 14 meters
(45 feet) in height, that inundated the
Fukushima Dai-ichi nuclear power plant
site. The earthquake and tsunami
produced widespread devastation across
northeastern Japan and significantly
affected the infrastructure and industry
in the northeastern coastal areas of
Japan. When the earthquake occurred,
Fukushima Dai-ichi Units 1, 2, and 3
were in operation and Units 4, 5, and 6
were shut down for routine refueling
and maintenance activities. The Unit 4
reactor fuel was offloaded to the Unit 4
spent fuel pool. Following the
earthquake, the three operating units
automatically shut down and offsite
power was lost to the entire facility. The
emergency diesel generators (EDG)
started at all six units providing
alternating current (ac) electrical power
to critical systems at each unit. The
facility response to the earthquake
appears to have been normal.
Approximately 40 minutes following
the earthquake and shutdown of the
operating units, however, the first large
tsunami wave inundated the site,
followed by additional waves. The
tsunami caused extensive damage to site
facilities and resulted in a complete loss
of all ac electrical power at Units 1
through 5, a condition known as station
blackout. In addition, all direct current
electrical power was lost early in the
event on Units 1 and 2, and after some
period of time at the other units. Unit
6 retained the function of one air-cooled
EDG. Despite their actions, the operators
lost the ability to cool the fuel in the
Unit 1 reactor after several hours, in the
Unit 2 reactor after about 70 hours, and
VerDate Mar<15>2010
17:00 Jan 14, 2013
Jkt 229001
in the Unit 3 reactor after about 36
hours, resulting in damage to the
nuclear fuel shortly after the loss of
cooling capabilities.
Following the events at the
Fukushima Dai-ichi nuclear power
plant, the NRC established a senior-level
agency task force referred to as the NearTerm Task Force (NTTF). The NTTF
was tasked with conducting a
systematic and methodical review of the
NRC’s regulations and processes, and
determining if the agency should make
additional improvements to these
programs in light of the events at
Fukushima Dai-ichi. As a result of this
review, the NTTF developed a
comprehensive set of recommendations,
documented in SECY–11–0093, ‘‘NearTerm Report and Recommendations for
Agency Actions Following the Events in
Japan,’’ dated July 12, 2011 (ADAMS
Accession No. ML11186A950). These
recommendations were enhanced by the
NRC staff following interactions with
stakeholders. Documentation of the
staff’s efforts is contained in SECY–11–
0124, ‘‘Recommended Actions to be
Taken Without Delay from the NearTerm Task Force Report,’’ dated
September 9, 2011 (ADAMS Accession
No. ML11245A158), and SECY–11–
0137, ‘‘Prioritization of Recommended
Actions to be Taken in Response to
Fukushima Lessons Learned,’’ dated
October 3, 2011 (ADAMS Accession No.
ML11272A111).
As directed by the Commission’s staff
requirements memorandum (SRM) for
SECY–11–0093, dated August 19, 2011
(ADAMS Accession No. ML112310021),
the NRC staff reviewed the NTTF
recommendations within the context of
the NRC’s existing regulatory framework
and considered the various regulatory
vehicles available to the NRC to
implement the recommendations.
SECY–11–0124 and SECY–11–0137
established the staff’s prioritization of
the recommendations based upon the
potential for each recommendation to
enhance safety.
As part of the SRM for SECY–11–
0124, dated October 18, 2011, the
Commission approved the staff’s
proposed actions, including the
development of three information
requests under 10 CFR 50.54(f). The
information collected would be used to
support the NRC staff’s evaluation of
whether further regulatory action was
needed in the areas of seismic and
flooding design and emergency
preparedness.
In addition to Commission direction,
the Consolidated Appropriations Act,
Public Law 112–074, was signed into
law on December 23, 2011. Section 402
of the law directs the NRC to require
PO 00000
Frm 00102
Fmt 4703
Sfmt 4703
licensees to reevaluate their design basis
for external hazards.
In response to the aforementioned
Commission and Congressional
direction, the NRC issued a request for
information to all power reactor
licensees and holders of construction
permits under 10 CFR Part 50 on March
12, 2012. The letter dated March 12,
2012, includes a request that licensees
reevaluate flooding hazards at nuclear
power plant sites using updated
flooding hazard information and
present-day regulatory guidance and
methodologies. The letter also requests
the comparison of the reevaluated
hazard to the current design basis at the
site for each potential flood mechanism.
If the reevaluated flood hazard at a site
is not bounded by the current design
basis, licensees are requested to perform
an integrated assessment. The integrated
assessment will evaluate the total plant
response to the flood hazard,
considering multiple and diverse
capabilities such as physical barriers,
temporary protective measures, and
operational procedures. The NRC staff
will review the licensees’ responses to
this request for information and
determine whether regulatory actions
are necessary to provide additional
protection against flooding.
Numerous public meetings were held
to receive stakeholder input on the
proposed guidance prior to its issuance
formally for public comment. On
October 26, 2012 (77 FR 65417), the
NRC requested public comments on
draft JLD–ISG–2012–06. The staff
received thirty-eight (38) comments
from four (4) stakeholders. Comments
were received related to the following
topical areas: (1) General comments; (2)
comments specific to the storm surge
evaluation; and (3) comments specific to
the tsunami evaluation. In public
meetings on October 24–25, 2012, and
November 14, 2012, the NRC staff
interacted extensively with external
stakeholders to discuss, understand, and
resolve public comments. Modifications
were made to the text of the ISG in
response to the public comments and
the outcomes of the public meetings.
Full detail of the comments, staff
responses, and the staff’s bases for
changes to the ISG are contained in
‘‘NRC Response to Public Comments’’ to
JLD–ISG–2012–06, which can be found
under ADAMS Accession No.
ML12314A414.
Backfitting and Issue Finality
This ISG does not constitute
backfitting as defined in 10 CFR 50.109
(the Backfit Rule) and is not otherwise
inconsistent with the issue finality
provisions in 10 CFR part 52, ‘‘Licenses,
E:\FR\FM\15JAN1.SGM
15JAN1
Federal Register / Vol. 78, No. 10 / Tuesday, January 15, 2013 / Notices
Certifications, and Approvals for
Nuclear Power Plants.’’ This ISG
provides guidance on an acceptable
method for implementing the March 12,
2012, request for information. Neither
the information request nor the ISG
require the modification or addition to
systems, structures, or components, or
design of a facility. Applicants and
licensees may voluntarily use the
guidance in JLD–ISG–2012–06 to
comply with the request for
information. The information received
by this request may, at a later date, be
used in the basis for imposing a backfit.
The appropriate backfit review process
would be followed at that time.
Congressional Review Act
This interim staff guidance is a rule as
designated in the Congressional Review
Act (5 U.S.C. 801–808). OMB has found
that this is not a major rule in
accordance with the Congressional
Review Act.

To support an application for a
spouse or widow(er)’s annuity under
Sections 2(c) or 2(d) of the Railroad
Retirement Act, an applicant must
submit proof of a valid marriage to a
railroad employee. In some cases, the
existence of a marital relationship is not
formalized by a civil or religious
ceremony. In other cases, questions may
arise about the legal termination of a
prior marriage of the employee, spouse,
or widow(er). In these instances, the
RRB must secure additional information
to resolve questionable marital
relationships. The circumstances
requiring an applicant to submit
documentary evidence of marriage are
prescribed in 20 CFR 219.30.
In the absence of documentary
evidence, the RRB needs to determine if
a valid marriage existed between a
spouse or widow(er) annuity applicant
and a railroad employee. The RRB

SUPPLEMENTARY INFORMATION:
Background Information
The NRC staff developed JLD-ISG-2012-06 to provide guidance and
clarification to assist nuclear power reactor licensees, applicants for
power reactor licenses, and holders of construction permits in active
or deferred status with the performance of a tsunami, surge, or seiche
hazard assessment.
On March 11, 2011, a magnitude 9.0 earthquake struck off the coast
of the Japanese island of Honshu. The earthquake resulted in a large
tsunami, estimated to have exceeded 14 meters (45 feet) in height, that
inundated the Fukushima Dai-ichi nuclear power plant site. The
earthquake and tsunami produced widespread devastation across
northeastern Japan and significantly affected the infrastructure and
industry in the northeastern coastal areas of Japan. When the
earthquake occurred, Fukushima Dai-ichi Units 1, 2, and 3 were in
operation and Units 4, 5, and 6 were shut down for routine refueling
and maintenance activities. The Unit 4 reactor fuel was offloaded to
the Unit 4 spent fuel pool. Following the earthquake, the three
operating units automatically shut down and offsite power was lost to
the entire facility. The emergency diesel generators (EDG) started at
all six units providing alternating current (ac) electrical power to
critical systems at each unit. The facility response to the earthquake
appears to have been normal. Approximately 40 minutes following the
earthquake and shutdown of the operating units, however, the first
large tsunami wave inundated the site, followed by additional waves.
The tsunami caused extensive damage to site facilities and resulted in
a complete loss of all ac electrical power at Units 1 through 5, a
condition known as station blackout. In addition, all direct current
electrical power was lost early in the event on Units 1 and 2, and
after some period of time at the other units. Unit 6 retained the
function of one air-cooled EDG. Despite their actions, the operators
lost the ability to cool the fuel in the Unit 1 reactor after several
hours, in the Unit 2 reactor after about 70 hours, and in the Unit 3
reactor after about 36 hours, resulting in damage to the nuclear fuel
shortly after the loss of cooling capabilities.
Following the events at the Fukushima Dai-ichi nuclear power plant,
the NRC established a senior-level agency task force referred to as the
Near-Term Task Force (NTTF). The NTTF was tasked with conducting a
systematic and methodical review of the NRC's regulations and
processes, and determining if the agency should make additional
improvements to these programs in light of the events at Fukushima Dai-
ichi. As a result of this review, the NTTF developed a comprehensive
set of recommendations, documented in SECY-11-0093, ``Near-Term Report
and Recommendations for Agency Actions Following the Events in Japan,''
dated July 12, 2011 (ADAMS Accession No. ML11186A950). These
recommendations were enhanced by the NRC staff following interactions
with stakeholders. Documentation of the staff's efforts is contained in
SECY-11-0124, ``Recommended Actions to be Taken Without Delay from the
Near-Term Task Force Report,'' dated September 9, 2011 (ADAMS Accession
No. ML11245A158), and SECY-11-0137, ``Prioritization of Recommended
Actions to be Taken in Response to Fukushima Lessons Learned,'' dated
October 3, 2011 (ADAMS Accession No. ML11272A111).
As directed by the Commission's staff requirements memorandum (SRM)
for SECY-11-0093, dated August 19, 2011 (ADAMS Accession No.
ML112310021), the NRC staff reviewed the NTTF recommendations within
the context of the NRC's existing regulatory framework and considered
the various regulatory vehicles available to the NRC to implement the
recommendations. SECY-11-0124 and SECY-11-0137 established the staff's
prioritization of the recommendations based upon the potential for each
recommendation to enhance safety.
As part of the SRM for SECY-11-0124, dated October 18, 2011, the
Commission approved the staff's proposed actions, including the
development of three information requests under 10 CFR 50.54(f). The
information collected would be used to support the NRC staff's
evaluation of whether further regulatory action was needed in the areas
of seismic and flooding design and emergency preparedness.
In addition to Commission direction, the Consolidated
Appropriations Act, Public Law 112-074, was signed into law on December
23, 2011. Section 402 of the law directs the NRC to require licensees
to reevaluate their design basis for external hazards.
In response to the aforementioned Commission and Congressional
direction, the NRC issued a request for information to all power
reactor licensees and holders of construction permits under 10 CFR Part
50 on March 12, 2012. The letter dated March 12, 2012, includes a
request that licensees reevaluate flooding hazards at nuclear power
plant sites using updated flooding hazard information and present-day
regulatory guidance and methodologies. The letter also requests the
comparison of the reevaluated hazard to the current design basis at the
site for each potential flood mechanism. If the reevaluated flood
hazard at a site is not bounded by the current design basis, licensees
are requested to perform an integrated assessment. The integrated
assessment will evaluate the total plant response to the flood hazard,
considering multiple and diverse capabilities such as physical
barriers, temporary protective measures, and operational procedures.
The NRC staff will review the licensees' responses to this request for
information and determine whether regulatory actions are necessary to
provide additional protection against flooding.
Numerous public meetings were held to receive stakeholder input on
the proposed guidance prior to its issuance formally for public
comment. On October 26, 2012 (77 FR 65417), the NRC requested public
comments on draft JLD-ISG-2012-06. The staff received thirty-eight (38)
comments from four (4) stakeholders. Comments were received related to
the following topical areas: (1) General comments; (2) comments
specific to the storm surge evaluation; and (3) comments specific to
the tsunami evaluation. In public meetings on October 24-25, 2012, and
November 14, 2012, the NRC staff interacted extensively with external
stakeholders to discuss, understand, and resolve public comments.
Modifications were made to the text of the ISG in response to the
public comments and the outcomes of the public meetings. Full detail of
the comments, staff responses, and the staff's bases for changes to the
ISG are contained in ``NRC Response to Public Comments'' to JLD-ISG-
2012-06, which can be found under ADAMS Accession No. ML12314A414.
Backfitting and Issue Finality
This ISG does not constitute backfitting as defined in 10 CFR
50.109 (the Backfit Rule) and is not otherwise inconsistent with the
issue finality provisions in 10 CFR part 52, ``Licenses,
[[Page 3041]]
Certifications, and Approvals for Nuclear Power Plants.'' This ISG
provides guidance on an acceptable method for implementing the March
12, 2012, request for information. Neither the information request nor
the ISG require the modification or addition to systems, structures, or
components, or design of a facility. Applicants and licensees may
voluntarily use the guidance in JLD-ISG-2012-06 to comply with the
request for information. The information received by this request may,
at a later date, be used in the basis for imposing a backfit. The
appropriate backfit review process would be followed at that time.
Congressional Review Act
This interim staff guidance is a rule as designated in the
Congressional Review Act (5 U.S.C. 801-808). OMB has found that this is
not a major rule in accordance with the Congressional Review Act.
Dated at Rockville, Maryland, this 4th day of January 2013.
For the Nuclear Regulatory Commission.

Acting Director, Japan Lessons-Learned Project Directorate, Office of
Nuclear Reactor Regulation.
