NUCLEAR REGULATORY COMMISSION


Regulatory Guide and Associated Standard Review Plan; Issuance, 
Availability

    The Nuclear Regulatory Commission (NRC) has issued for public 
comment a revision of a regulatory guide (and its associated Standard 
Review Plan). Regulatory Guides are developed to describe and make 
available to the public such information as methods acceptable to the 
NRC staff for implementing specific parts of the NRC's regulations, 
techniques used by the staff in its review of applications for permits 
and licenses, and data needed by NRC staff in its review of 
applications for permits and licenses.
    Regulatory Guide 1.200, Revision 1, ``An approach for Determining 
the Technical Adequacy of Probabilistic Risk Assessment Results for 
Risk-Informed Activities,'' provides guidance to licensees in 
determining the technical adequacy of a probabilistic risk analysis 
used in a risk-informed, integrated decision-making process, and to 
endorse standards and industry guidance. Guidance is provided in four 
areas:
    (1) A minimal set of functional requirements of a technically 
acceptable PRA.
    (2) NRC position on consensus PRA standards and industry PRA 
program documents.
    (3) Demonstration that the PRA (in toto or specific parts) used in 
regulatory applications is of sufficient technical adequacy.
    (4) Documentation that the PRA (in toto or specific parts) used in 
regulatory applications is of sufficient technical adequacy.
    RG 1.200, Revision 1, proposes to endorse, with certain 
clarifications and substitutions, ASME Standard, ``Standard for 
Probabilistic Risk Assessment for Nuclear Power Plant Applications'' 
(RA-S-2002, RA-Sa-2003 and RA-Sb-2005, dated April 5, 2002, December 5, 
2003, and December 30, 2005, respectively), Revision A3 of NEI-00-02, 
``Probabilistic Risk (PRA) Peer Review Process Guidance,'' with its 
August 16, 2002 and May 19, 2006 supplemental guidance on industry 
self-assessment, and NEI-05-04, ``Process for Performing Follow-on PRA 
Peer Reviews Using the ASME PRA Standard,'' January 2005.
    Standard Review Plan Chapter 19.1, Revision 1, ``Determining the 
Technical Adequacy of Probabilistic Risk and Assessment Results for 
Risk-Informed Activities,'' has been developed for the NRC staff to use 
in conjunction with Regulatory Guide 1.200, Revision 1.
    It is the NRC's intent to update this RG when a new or revised PRA 
standard or industry program is published. If a new standard or program 
is published, an additional appendix will be added to set forth the 
staff position. If a revision of a current standard or program would 
impact the staff position, the appropriate appendix would be revised.
    The NRC staff is soliciting comments on these proposed documents. 
Comments may be accompanied by relevant information or supporting data. 
Written comments may be submitted to the Rules and Directives Branch, 
Office of Administration, U.S. Nuclear Regulatory Commission, 
Washington, DC 20555. Copies of comments received may be examined at 
the NRC Public Document Room, 11555 Rockville Pike, Rockville, MD. 
Comments will be most helpful if received by September 15, 2006.
    Comments received after this date will be considered if it is 
practical to do so, but the NRC is able to ensure consideration only 
for comments received on or before this date.
    You may also provide comments via the NRC's interactive rulemaking 
Web site through the NRC home page (http://www.nrc.gov). This site 
provides the ability to upload comments as files (any format) if your 
web browser supports that function. For information about the 
interactive rulemaking Web site, contact Ms. Carol Gallagher, (301)

the related standard review plan chapter, contact Ms. M.T. Drouin at 
(301)415-6675; e-mail [email protected].
    Although a time limit is given for comments on this draft guide, 
comments and suggestions in connection with items for inclusion in 
guides currently being developed or improvements in all published 
guides are encouraged at any time.
    Electronic copies of this draft RG are available on the NRC's Web 
site http://www.nrc.gov in the Reference Library under Regulatory 
Guides. Electronic copies are also available in NRC's Public Electronic 
Reading Room at the same Web site; DG-1122 is under ADAMS Accession
