FOR FURTHER INFORMATION CONTACT: Mr. Ian C. Jung, Chief,
Instrumentation, Controls and Electrical Engineering Branch 2, Division
of Engineering, Office of New Reactors, U.S. Nuclear Regulatory
Commission, Washington, DC 20555-0001; telephone: 301-415-2969 or email

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.

Chief, Policy Branch, Division of Advanced Reactors and Rulemaking,
