[7590-01-P] Nuclear Regulatory Commission Office of New Reactors; Proposed Standard Review Plan Appendix 18-A on Guidance for Crediting Manual Operator Actions in Diversity and Defense-in-Depth (D3) Analyses [NRC-2009-0515] AGENCY: Nuclear Regulatory Commission (NRC). ACTION: Solicitation of public comment. SUMMARY: The NRC staff is soliciting public comment on NUREG-0800, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants,” (SRP) Appendix 18-A on Guidance for Crediting Manual Operator Actions in Diversity and Defense-in-Depth (D3) Analyses (Agencywide Documents Access and Management System (ADAMS) Accession No. ML092950353). This Appendix defines a methodology for evaluating manual operator action as a diverse means of coping with Anticipated Operational Occurrences and Postulated Accidents that are concurrent with a software Common Cause Failure of the Digital Instrumentation and Control (I&C) Protection System. This Appendix supersedes, and incorporates with limited modifications, the guidance in Section 3 of Digital I&C Interim Staff Guidance (ISG), Digital I&C-ISG-05, Revision 1, Highly Integrated Control Rooms—Human Factors Issues. The NRC staff issues SRPs to facilitate timely implementation of current staff guidance and to facilitate activities associated with the review of applications for design certification (DC) and combined licenses (COLs) by the Office of New Reactors (NRO). The NRC staff will also incorporate the revised SRP section and Appendix 18-A into the next revisions of Regulatory Guide 1.206 and any related guidance documents. - 2 - DATES: Comments must be filed no later than 60 days from the date of publication of this notice in the Federal Register.
