SUPPLEMENTARY INFORMATION:
The NRC staff issues SRPs and BTPs to facilitate timely implementation of current staff guidance and to facilitate activities associated with the review of applications for design certifications and combined licenses by the Office of New Reactors. Additionally, the SRPs and BTPs are used by the Office of Nuclear Reactor Regulation staff in the review of applications for license amendments in currently operating nuclear power plants. The NRC staff will also incorporate the revised SRP section and BTP 7-19 into the next revision of Regulatory Guide 1.206 and any related guidance documents.
On March 19, 2010, the NRC staff issued the proposed Revision 6 of NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition,” BTP 7-19 on “Guidance for Evaluation of Diversity and Defense-in-Depth in Digital Computer-Based Instrumentation and Control Systems” (ADAMS Accession No. ML093490771). The NRC staff considered comments received on the proposed revision to BTP 7-19 as well as recommendations from the ACRS, and incorporated the changes suggested in the comments in this final issuance. The NRC staff responses to these comments can be found under ADAMS Accession No. ML120830075.
Backfitting: This SRP update does not constitute backfitting as defined in Title 10 of the Code of Federal Regulations (10 CFR) 50.109, nor is it inconsistent with any of the issue finality provisions in 10 CFR Part 52. This SRP does not contain any new requirements for COL applicants or holders under Part 52, or for licensees of existing operating units licensed under part 50. Rather, it contains additional guidance and clarification on compliance with 10 CFR 52.79(a)(31), which may be used by COL applicants in the preparation of their applications.
Congressional Review Act: This SRP update is a rule as designated in the Congressional Review Act (5 U.S.C. 801-808). However, OMB has not found it to be a major rule as designated in the Congressional Review Act.
Dated at Rockville, Maryland, this 16th day of July 2012.
For the Nuclear Regulatory Commission.
