Start Supplemental Information
The NRC published a Federal Register notice requesting public comment on this interim staff guidance (ISG) on February 23, 2017 (82 FR 11483). The agency received five total comments. The NRC considered the comments, which resulted in no changes to the ISG. The evaluation of these comments is discussed in the last appendix of the ISG.
The Office of Nuclear Reactor Regulation (NRR), Division of Risk Analysis (DRA) completed a generic bounding risk analysis (ADAMS Accession No. ML14114A556) that concluded that the issues associated with the inoperability of a Structure, System, or Component due to a tornado-generated missile are likely to be of low risk significance, and do not require immediate plant shutdown. Based on the conclusions of the NRR/DRA analysis, the staff issued EGM 15-002, dated June 10, 2015. In its implementation of EGM 15-002, the NRC staff found that additional refinements are needed to address reportability, enforcement of long standing design issues, and the duration of the enforcement discretion resulting from all the non-conforming conditions being assessed together. As a result, the staff issued EGM 15-002, Revision 1, dated February 7, 2017.
This revised ISG adds additional information for inspection and review staff to support implementation of the changes made in EGM 15-002, Revision 1. This revised ISG provides an approach to extending the discretion. The revisions to this ISG also revise provisions concerning reportability requirements under § 50.72 of title 10 of the Code of Federal Regulations (10 CFR), discusses enforcement discretion for long-term design non conformances, and reinforces the need for licensees to follow the corrective action program when dispositioning the impact of identified tornado missile non-conformances on operability. This revised ISG will expire with the expiration of EGM 15-002, Revision 1.
II. Backfit Discussion
Issuance of this ISG in final form does not constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule). As discussed in the “Backfitting” section of DSS-ISG- 2016-001, Revision 1, this ISG contains guidance for the NRC staff for implementing EGM-15-002. This ISG does not constitute backfitting as defined in the Backfit Rule and is not otherwise inconsistent with the issue finality provisions in 10 CFR part 52, and the NRC staff did not prepare a backfit analysis. This because this ISG requires no response by licensees, and concerns only NRC staff implementation of enforcement discretion pursuant to EGM-15-002.
III. Congressional Review Act
This 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.
