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

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 

DATES: Comments must be filed no later than 60 days from the date of 
publication of this notice in the Federal Register. Comments received

received on or before this date.

comments. Comments submitted in writing or in electronic form will be

remove any identifying or contact information, the NRC cautions you 
against including any information in your submission that you do not 
want to be publicly disclosed.
    The NRC requests that any party soliciting or aggregating comments 
received from other persons for submission to the NRC inform those 
persons that the NRC will not edit their comments to remove any 
identifying or contact information, and therefore, they should not 
include any information in their comments that they do not want 
publicly disclosed.

SUPPLEMENTARY INFORMATION: This SRP, NUREG-0800, has been prepared to 
establish criteria that the NRO staff use to evaluate if DC and COL 
applications meet the NRC's regulations. The SRP is not a substitute 
for the NRC's regulations, and compliance with it is not required. 
However, applicants are required to identify differences in design 
features, analytical techniques, and procedural measures proposed for a 
facility and corresponding SRP acceptance criteria, and evaluate how 
the proposed alternatives to the acceptance criteria provide an 
acceptable method of complying with the NRC's regulations.
    The agency posts its issued staff guidance in the agency external 
Web page (http://www.nrc.gov/reading-rm/doc-collections/nuregs/staff/sr0800).
    The NRC staff is issuing this notice to solicit public comments on 
proposed Appendix 18-A, which is being issued for the first time. After 
the NRC staff considers any public comments, it will make a 
determination regarding proposed Appendix 18-A.

    Dated at Rockville, Maryland, this 20th day of November 2009.

    For the Nuclear Regulatory Commission.
William F. Burton,
Chief, Rulemaking and Guidance Development Branch, Division of New 
Reactor Licensing, Office of New Reactors.
