SUPPLEMENTARY INFORMATION: II. Background Information The NRC staff developed draft JLD– ISG–2012–01 to provide guidance and clarification to assist nuclear power reactor applicants and licensees with the identification of measures needed to comply with requirements to mitigate challenges to key safety functions. These requirements are contained in Order EA–12–049, ‘‘Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for BeyondDesign-Basis External Events,’’ (ADAMS Accession No. ML12054A736). The draft ISG is not a substitute for the requirements in Order EA–12–049, and compliance with the ISG is not required. This ISG is being issued in draft form for public comment to involve the public in development of the implementation guidance. 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 andsignificantly 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 (SFP). Following the earthquake, the three operating units automatically shut down and offsite power was lost to the entire facility. The emergency diesel generators 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. Following the events at the Fukushima Dai-ichi nuclear power E:\FR\FM\07JNN1.SGM 07JNN1 srobinson on DSK4SPTVN1PROD with NOTICES 33780 Federal Register / Vol. 77, No. 110 / Thursday, June 7, 2012 / Notices 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 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 requirement memorandum (SRM) for SECY–11–0093 (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. After receiving the Commission’s direction in SRM–SECY–11–0124 (ADAMS Accession No. ML112911571) and SRM–SECY–11–0137 (ADAMS Accession No. ML113490055), the NRC staff conducted public meetings to discuss enhanced mitigation strategies intended to maintain or restore core cooling, containment, and SFP cooling capabilities following beyond-designbasis external events. At these meetings, the industry described its proposal for a Diverse and Flexible Mitigation Capability (FLEX), as documented in the Nuclear Energy Institute’s (NEI’s) letter, dated December 16, 2011 (ADAMS Accession No. ML11353A008). FLEX is proposed as a strategy to fulfill the key safety functions of core cooling, containment integrity, and spent fuel cooling. Stakeholder input influenced the staff to pursue a more performancebased approach to improve the safety of operating power reactors than was VerDate Mar<15>2010 17:48 Jun 06, 2012 Jkt 226001 originally envisioned in NTTF Recommendation 4.2, SECY–11–0124, and SECY–11–0137. On February 17, 2012, the NRC staff provided SECY–12–0025, ‘‘Proposed Orders and Requests for Information in Response to Lessons Learned from Japan’s March 11, 2011, Great Tohoku Earthquake and Tsunami’’ (ADAMS Accession No. ML12039A103) to the Commission, including the proposed order to implement the enhanced mitigation strategies. As directed by SRM–SECY–12–0025 (ADAMS Accession No. ML120690347), the NRC staff issued Order EA–12–049, ‘‘Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events’’ (ADAMS Accession No. ML12073A195). On March 30, 2012, the Commission issued memorandum and Order CLI–12–09, ‘‘In the Matter of South Carolina Electric & Gas Co. and South Carolina Public Service Authority (Also Referred to as Santee Cooper; Virgil C. Summer Nuclear Station, Units 2 and 3),’’ (ADAMS Accession No. ML12090A531), which includes the requirements for mitigation strategies as a license condition for Virgil C. Summer Nuclear Station, Units 2 and 3. Guidance and strategies required by the Order would be available if the loss of power, motive force and normal access to the ultimate heat sink to prevent fuel damage in the reactor, and SFP affected all units at a site simultaneously. The Order requires a three-phase approach for mitigating beyond-design-basis external events. The initial phase requires the use of installed equipment and resources to maintain or restore core cooling, containment, and SFP cooling. The transition phase requires providing sufficient, portable, onsite equipment and consumables to maintain or restore these functions until they can be accomplished with resources brought from off site. The final phase requires obtaining sufficient offsite resources to sustain those functions indefinitely. On May 4, 2012, NEI submitted document 12–06, ‘‘Diverse and Flexible Coping Strategies (FLEX) Implementation Guide,’’ Revision B (ADAMS Accession No. ML12128A124), and on May 13, 2012, Revision B1 (ADAMS Accession No. ML12143A232), to provide specifications for an industry-developed methodology for the development, implementation, and maintenance of guidance and strategies in response to the mitigating strategies Order. The strategies and guidance described in NEI 12–06 expand on the strategies the industry developed and implemented to address the limited set PO 00000 Frm 00078 Fmt 4703 Sfmt 4703 of beyond-design-basis external events that involve the loss of a large area of the plant due to explosions and fire required pursuant to paragraph (hh)(2) of Title 10 of the Code of Federal Regulations (10 CFR) 50.54, ‘‘Conditions of licenses.’’ Proposed Action By this action, the NRC is requesting public comments on draft JLD–ISG– 2012–01.

II. Background Information

    The NRC staff developed draft JLD-ISG-2012-01 to provide guidance 
and clarification to assist nuclear power reactor applicants and 
licensees with the identification of measures needed to comply with 
requirements to mitigate challenges to key safety functions. These 
requirements are contained in Order EA-12-049, ``Order Modifying 
Licenses with Regard to Requirements for Mitigation Strategies for 
Beyond-Design-Basis External Events,'' (ADAMS Accession No. 
ML12054A736). The draft ISG is not a substitute for the requirements in 
Order EA-12-049, and compliance with the ISG is not required. This ISG 
is being issued in draft form for public comment to involve the public 
in development of the implementation guidance.
    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 andsignificantly affected the infrastructure and

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 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 requirement memorandum (SRM) 
for SECY-11-0093 (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.
    After receiving the Commission's direction in SRM-SECY-11-0124 
(ADAMS Accession No. ML112911571) and SRM-SECY-11-0137 (ADAMS Accession 
No. ML113490055), the NRC staff conducted public meetings to discuss 
enhanced mitigation strategies intended to maintain or restore core 
cooling, containment, and SFP cooling capabilities following beyond-
design-basis external events. At these meetings, the industry described 
its proposal for a Diverse and Flexible Mitigation Capability (FLEX), 
as documented in the Nuclear Energy Institute's (NEI's) letter, dated 
December 16, 2011 (ADAMS Accession No. ML11353A008). FLEX is proposed 
as a strategy to fulfill the key safety functions of core cooling, 
containment integrity, and spent fuel cooling. Stakeholder input 
influenced the staff to pursue a more performance-based approach to 
improve the safety of operating power reactors than was originally 
envisioned in NTTF Recommendation 4.2, SECY-11-0124, and SECY-11-0137.
    On February 17, 2012, the NRC staff provided SECY-12-0025, 
``Proposed Orders and Requests for Information in Response to Lessons 
Learned from Japan's March 11, 2011, Great Tohoku Earthquake and 
Tsunami'' (ADAMS Accession No. ML12039A103) to the Commission, 
including the proposed order to implement the enhanced mitigation 
strategies. As directed by SRM-SECY-12-0025 (ADAMS Accession No. 
ML120690347), the NRC staff issued Order EA-12-049, ``Order Modifying 
Licenses with Regard to Requirements for Mitigation Strategies for 
Beyond-Design-Basis External Events'' (ADAMS Accession No. 
ML12073A195). On March 30, 2012, the Commission issued memorandum and 
Order CLI-12-09, ``In the Matter of South Carolina Electric & Gas Co. 
and South Carolina Public Service Authority (Also Referred to as Santee 
Cooper; Virgil C. Summer Nuclear Station, Units 2 and 3),'' (ADAMS 
Accession No. ML12090A531), which includes the requirements for 
mitigation strategies as a license condition for Virgil C. Summer 
Nuclear Station, Units 2 and 3.
    Guidance and strategies required by the Order would be available if 
the loss of power, motive force and normal access to the ultimate heat 
sink to prevent fuel damage in the reactor, and SFP affected all units 
at a site simultaneously. The Order requires a three-phase approach for 
mitigating beyond-design-basis external events. The initial phase 
requires the use of installed equipment and resources to maintain or 
restore core cooling, containment, and SFP cooling. The transition 
phase requires providing sufficient, portable, onsite equipment and 
consumables to maintain or restore these functions until they can be 
accomplished with resources brought from off site. The final phase 
requires obtaining sufficient offsite resources to sustain those 
functions indefinitely.
    On May 4, 2012, NEI submitted document 12-06, ``Diverse and 
Flexible Coping Strategies (FLEX) Implementation Guide,'' Revision B 
(ADAMS Accession No. ML12128A124), and on May 13, 2012, Revision B1 
(ADAMS Accession No. ML12143A232), to provide specifications for an 
industry-developed methodology for the development, implementation, and 
maintenance of guidance and strategies in response to the mitigating 
strategies Order. The strategies and guidance described in NEI 12-06 
expand on the strategies the industry developed and implemented to 
address the limited set of beyond-design-basis external events that 
involve the loss of a large area of the plant due to explosions and 
fire required pursuant to paragraph (hh)(2) of Title 10 of the Code of 
Federal Regulations (10 CFR) 50.54, ``Conditions of licenses.''

Proposed Action

    By this action, the NRC is requesting public comments on draft JLD-
ISG-2012-01. This draft JLD-ISG proposes guidance related to 
requirements contained in Order EA-12-049, Mitigation Strategies for 
Beyond-Design-Basis External Events. The NRC staff will make a final 
determination regarding issuance of the JLD-ISG after it considers any 
public comments received in response to this request.
