Interim staff guidance (ISG), Final Japan Lessons-Learned Project Directorate Interim Staff Guidance (JLD-ISG), JLD-ISG-2012-01,
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,
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.
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.
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.
