SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or the Commission)
is issuing the Final Japan Lessons-Learned Project Directorate Interim
Staff Guidance (JLD-ISG), JLD-ISG-2012-01, ``Compliance with Order EA-
12-049, Order Modifying Licenses with Regard to Requirements for
Mitigation Strategies for Beyond-Design-Basis External Events,''
Agencywide Documents Access and Management System (ADAMS) Accession No.
ML12229A174. This JLD-ISG provides 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).

SUPPLEMENTARY INFORMATION:
II. Background Information
Interim staff guidance (ISG), Final Japan Lessons-Learned Project
Directorate Interim Staff Guidance (JLD-ISG), JLD-ISG-2012-01,
``Compliance with Order EA-12-049, Order Modifying Licenses with Regard
to Requirements for Mitigation Strategies for Beyond-Design-Basis
External Events,'' (ADAMS Accession No. ML12229A174) is being issued to
describe to the public methods acceptable to the Nuclear Regulatory
Commission (NRC) staff for complying with Order EA-12-049, ``Order
Modifying Licenses with Regard to Requirements for Mitigation
Strategies for Beyond-Design-Basis External Events (Effective
Immediately)'' (Order EA-12-049), issued March 12, 2012. This ISG
endorses the methodologies described in the industry guidance document,
Nuclear Energy Institute (NEI) 12-06, Diverse and Flexible Coping
Strategies (FLEX) Implementation Guide (NEI 12-06), Revision 0 (ADAMS
Accession No. ML12242A378) submitted on August 21, 2012. The ISG is not
a substitute for the requirements in Order EA-12-049, and compliance
with this ISG is not required.
The NRC issued Order EA-12-049 following the NRC staff's evaluation
of the earthquake and tsunami, and resulting nuclear accident, at the
Fukushima Dai-ichi nuclear power plant in March 2011. Order EA-12-049
requires all licensees and construction permit (CP) holders to develop
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,
[[Page 55231]]
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. Order EA-12-049 also specified
that the NRC staff would issue final interim staff guidance in August
2012 to provide additional details on an acceptable approach for
complying with Order EA-12-049.
Numerous public meetings were held to solicit stakeholder input on
the proposed requirement for mitigation strategies prior to issuance of
Order EA-12-049. Following issuance of Order EA-12-049, several more
public meetings were held with representatives from the NEI task force
and public stakeholders to discuss development of the guidance for
compliance with Order EA-12-049. On June 7, 2012 (77 FR 33779), the NRC
requested public comments on draft JLD-ISG-12-01. The staff received
comments from eight stakeholders which were considered in the
development of the final JLD-ISG-12-01. The questions, comments and
staff resolutions of those comments are contained in ``JLD-ISG-2012-01,
Comment Resolution Rev.1'' which can be found in ADAMS as Accession No.
ML12229A253.
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 Part 52, ``Licenses, Certifications, and
Approvals for Nuclear Power Plants,'' of 10 CFR. This ISG provides
guidance on an acceptable method for implementing the requirements
contained in Order EA-12-049, which was issued as ensuring adequate
protection under the provisions of the backfit rule. Applicants and
licensees may voluntarily use the guidance in JLD-ISG-2012-01 to
demonstrate compliance with Order EA-12-049. Methods or solutions that
differ from those described in this ISG may be deemed acceptable if
they provide sufficient basis and information for the NRC staff to
verify that the proposed alternative demonstrates compliance with Order
EA-12-049.
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
a major rule in accordance with the Congressional Review Act.
Dated at Rockville, Maryland, this 29th day of August 2012.
For the Nuclear Regulatory Commission.
John D. Monninger,
Associate Director, Japan Lessons-Learned Project Directorate, Office
of Nuclear Reactor Regulation.
