I. Background
Following the events at the
Fukushima Dai-ichi nuclear power plant
on March 11, 2011, 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 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,
‘‘Recommendations for Enhancing
Reactor Safety in the 21st Century, the
Near-Term Task Force Review of
Insights from the Fukushima Dai-ichi
Accident,’’ dated July 12, 2011. These
recommendations were enhanced by the
NRC staff following interactions with
stakeholders. Documentation of the
staff’s efforts is contained in SECY–11–
0124, dated September 9, 2011, and
SECY–11–0137, dated October 3, 2011.
As directed by the Commission’s SRM
for SECY–11–0093, 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. In SECY–11–0124
and SECY–11–0137, the staff
established the prioritization of the
recommendations. After receiving the
Commission’s direction in SRM–SECY–
11–0124 and SRM–SECY–11–0137, the
NRC staff issued a request for
information pursuant to section 50.54(f)
of title 10 of the Code of Federal
Regulations (10 CFR), ‘‘Conditions of
licenses,’’ on March 12, 2012, requesting
licensees to reevaluate the seismic and
flooding hazards at their sites using
VerDate Sep<11>2014
19:39 Jul 18, 2016
Jkt 238001
updated hazard information and current
regulatory guidance and methodologies.
For plants where the reevaluated hazard
exceeds the plant’s design basis, the
licensee was to conduct an integrated
assessment. The information gathering
is considered to be Phase 1 and was
requested to support Phase 2 decisionmaking and determine whether
available or planned measures provide
sufficient protection and mitigation
capabilities or if further regulatory
action should be pursued in the areas of
seismic and flooding design, and
emergency preparedness.
In COMSECY–14–0037, dated
November 21, 2014, the NRC staff
requested that the Commission review
and approve changes to revise the
Recommendation 2.1 flooding
assessments and integrate the Phase 2
decision-making into the development
and implementation of mitigating
strategies in accordance with Order EA–
12–049 and the related Mitigation of
Beyond-Design-Basis Events
rulemaking.
In SRM–COMSECY–14–0037, the
Commission disapproved this
recommendation. Instead, the
Commission instructed the staff to
develop a closure plan for the flooding
reevaluation activities and to reassess
the existing guidance for performing a
Phase 1 integrated assessment in order
to focus on those plants with the most
potential for safety benefits.
In COMSECY–15–0019, the staff
provided revised guidance for
performing a Phase 1 integrated
assessment and described a modified
process for identifying the list of plants
that would be required to perform an
integrated assessment. The process
proposed by the staff included the
development of a graded, risk-informed
and performance-based approach
consistent with Commission direction to
focus on those plants with the greatest
potential opportunity for safety
enhancements. Specifically, the process
included consideration and evaluation
of local intense precipitation by
performing a focused evaluation of the
impact of the hazard and implementing
any necessary programmatic,
procedural, or plant modifications to
address the hazard, taking into account
available warning time. The process also
considered flood protection and
available physical margin, where
licensees will confirm the capability of
existing flood protection to address the
hazard exceedance by performing a
focused evaluation. For licensees where
the reevaluated hazard cannot be
addressed via existing or planned flood
protection, the process also includes the
performance of an integrated
PO 00000
Frm 00086
Fmt 4703
Sfmt 4703
46971
assessment, using revised guidance, in
order to conduct more detailed
evaluations of plant response capability.
This revised integrated assessment will
capture, among other information,
quantitative characteristics about the
effectiveness of various aspects of plant
response (e.g., reliability of equipment
and feasibility of manual actions), and
risk insights with a focus on cliff-edge
effects. The results will be used by the
NRC to determine whether additional
regulatory action, such as a plantspecific backfit, are warranted.
In SRM–COMSECY–15–0019, the
Commission approved the staff’s plans
to modify the approach for integrated
assessments to implement a graded
approach for determining the need for,
and prioritization and scope of, plantspecific integrated assessments. As
discussed in COMSECY–15–0019, the
majority of sites with reevaluated
flooding hazards exceeding the designbasis flood are expected to screen out
from the integrated assessment process.
The licensees will instead provide
focused evaluations to ensure
appropriate actions are taken and that
these actions are effective and
reasonable.
The Nuclear Energy Institute (NEI)
submitted guidance NEI 16–05,
‘‘External Flooding Assessment
Guidelines,’’ Revision 1, on June 10,
2016. The revised guidance is an
industry-developed methodology that
describes the flooding impact
assessment process, which is intended
to meet the requested information of an
integrated assessment, as described in
the document titled, ‘‘Request for
Information Pursuant to Title 10 of the
Code of Federal Regulations (10 CFR)
50.54(f) Regarding Recommendations
2.1, 2.3, and 9.3, of the Near-Term Task
Force Review of Insights from the
Fukushima Dai-ichi Accident,’’ and to
incorporate the changes described in
COMSECY–15–0019. This revised
guidance will be publicly available and
used by members of the industry to help
develop their responses to the § 50.54(f)
letter, including the performance of
focused evaluations and integrated
assessments, and by the NRC staff in its
reviews of the licensees’ evaluation.
On April 22, 2016 (81 FR 23758), the
NRC requested public comments on
draft JLD–ISG–2016–01. The NRC staff
received comments from two
stakeholders which were considered in
the development of the final JLD–ISG–
16–01. The questions, comments, and
staff resolutions of those comments are
contained in ‘‘NRC Responses to Public

SUPPLEMENTARY INFORMATION:
I. Background
Following the events at the Fukushima Dai-ichi nuclear power plant
on March 11, 2011, 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
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,
``Recommendations for Enhancing Reactor Safety in the 21st Century, the
Near-Term Task Force Review of Insights from the Fukushima Dai-ichi
Accident,'' dated July 12, 2011. These recommendations were enhanced by
the NRC staff following interactions with stakeholders. Documentation
of the staff's efforts is contained in SECY-11-0124, dated September 9,
2011, and SECY-11-0137, dated October 3, 2011.
As directed by the Commission's SRM for SECY-11-0093, 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. In
SECY-11-0124 and SECY-11-0137, the staff established the prioritization
of the recommendations. After receiving the Commission's direction in
SRM-SECY-11-0124 and SRM-SECY-11-0137, the NRC staff issued a request
for information pursuant to section 50.54(f) of title 10 of the Code of
Federal Regulations (10 CFR), ``Conditions of licenses,'' on March 12,
2012, requesting licensees to reevaluate the seismic and flooding
hazards at their sites using updated hazard information and current
regulatory guidance and methodologies. For plants where the reevaluated
hazard exceeds the plant's design basis, the licensee was to conduct an
integrated assessment. The information gathering is considered to be
Phase 1 and was requested to support Phase 2 decision-making and
determine whether available or planned measures provide sufficient
protection and mitigation capabilities or if further regulatory action
should be pursued in the areas of seismic and flooding design, and
emergency preparedness.
In COMSECY-14-0037, dated November 21, 2014, the NRC staff
requested that the Commission review and approve changes to revise the
Recommendation 2.1 flooding assessments and integrate the Phase 2
decision-making into the development and implementation of mitigating
strategies in accordance with Order EA-12-049 and the related
Mitigation of Beyond-Design-Basis Events rulemaking.
In SRM-COMSECY-14-0037, the Commission disapproved this
recommendation. Instead, the Commission instructed the staff to develop
a closure plan for the flooding reevaluation activities and to reassess
the existing guidance for performing a Phase 1 integrated assessment in
order to focus on those plants with the most potential for safety
benefits.
In COMSECY-15-0019, the staff provided revised guidance for
performing a Phase 1 integrated assessment and described a modified
process for identifying the list of plants that would be required to
perform an integrated assessment. The process proposed by the staff
included the development of a graded, risk-informed and performance-
based approach consistent with Commission direction to focus on those
plants with the greatest potential opportunity for safety enhancements.
Specifically, the process included consideration and evaluation of
local intense precipitation by performing a focused evaluation of the
impact of the hazard and implementing any necessary programmatic,
procedural, or plant modifications to address the hazard, taking into
account available warning time. The process also considered flood
protection and available physical margin, where licensees will confirm
the capability of existing flood protection to address the hazard
exceedance by performing a focused evaluation. For licensees where the
reevaluated hazard cannot be addressed via existing or planned flood
protection, the process also includes the performance of an integrated
assessment, using revised guidance, in order to conduct more detailed
evaluations of plant response capability. This revised integrated
assessment will capture, among other information, quantitative
characteristics about the effectiveness of various aspects of plant
response (e.g., reliability of equipment and feasibility of manual
actions), and risk insights with a focus on cliff-edge effects. The
results will be used by the NRC to determine whether additional
regulatory action, such as a plant- specific backfit, are warranted.
In SRM-COMSECY-15-0019, the Commission approved the staff's plans
to modify the approach for integrated assessments to implement a graded
approach for determining the need for, and prioritization and scope of,
plant-specific integrated assessments. As discussed in COMSECY-15-0019,
the majority of sites with reevaluated flooding hazards exceeding the
design-basis flood are expected to screen out from the integrated
assessment process. The licensees will instead provide focused
evaluations to ensure appropriate actions are taken and that these
actions are effective and reasonable.
The Nuclear Energy Institute (NEI) submitted guidance NEI 16-05,
``External Flooding Assessment Guidelines,'' Revision 1, on June 10,
2016. The revised guidance is an industry-developed methodology that
describes the flooding impact assessment process, which is intended to
meet the requested information of an integrated assessment, as
described in the document titled, ``Request for Information Pursuant to
Title 10 of the Code of Federal Regulations (10 CFR) 50.54(f) Regarding
Recommendations 2.1, 2.3, and 9.3, of the Near-Term Task Force Review
of Insights from the Fukushima Dai-ichi Accident,'' and to incorporate
the changes described in COMSECY-15-0019. This revised guidance will be
publicly available and used by members of the industry to help develop
their responses to the Sec. 50.54(f) letter, including the performance
of focused evaluations and integrated assessments, and by the NRC staff
in its reviews of the licensees' evaluation.
On April 22, 2016 (81 FR 23758), the NRC requested public comments
on draft JLD-ISG-2016-01. The NRC staff received comments from two
stakeholders which were considered in the development of the final JLD-
ISG-16-01. The questions, comments, and staff resolutions of those
comments are contained in ``NRC Responses to Public Comments: Revision

(ADAMS Accession No. ML16165A103).
II. Congressional Review Act
This JLD-ISG is a rule as defined in the Congressional Review Act
(5 U.S.C. 801-808). However, the Office of Management and Budget has
not found it to be a major rule as defined in the Congressional Review
Act.
