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 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 need for safety enhancements. Specifically, the process included consideration and evaluation of local intense precipitation by performing a focused evaluation of the impact of the E:\FR\FM\22APN1.SGM 22APN1 23760 Federal Register / Vol. 81, No. 78 / Friday, April 22, 2016 / Notices 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 reliability of various aspects of plant response (e.g., reliability of equipment and 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, 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 0, on April 12, 2016. The guidance is an industrydeveloped 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. Draft ISG JLD ISG 2016–01 is being issued to describe to stakeholders methods acceptable to the staff for performance of the focused evaluations and revised integrated assessments and describe some exceptions and clarifications to NEI 16–05, Revision 0. This guidance is not intended for use in design-basis applications or in regulatory activities beyond the scope of performing the focused evaluations and integrated assessment part of NTTF Recommendation 2.1 flooding activities.

II. 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 need for safety enhancements. 
Specifically, the process included consideration and evaluation of 
local intense precipitation by performing a focused evaluation of the 
impact of the

[[Page 23760]]

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 reliability of various aspects of plant 
response (e.g., reliability of equipment and 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 0, on April 12, 
2016. The 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.
    Draft ISG JLD ISG 2016-01 is being issued to describe to 
stakeholders methods acceptable to the staff for performance of the 
focused evaluations and revised integrated assessments and describe 
some exceptions and clarifications to NEI 16-05, Revision 0.
    This guidance is not intended for use in design-basis applications 
or in regulatory activities beyond the scope of performing the focused 
evaluations and integrated assessment part of NTTF Recommendation 2.1 
flooding activities. This ISG is being issued in draft form for public 
comment to involve the public in development of the implementation 
guidance. Compliance with the ISG is not required.
