Consequently, the NRC staff elected to remove Appendix B (and all related references) from this revision. Removal of Appendix B from this revised guide does not require any stakeholder to take any action and does not reduce safety in any way. Moreover, public meetings with the owners’ group Technical Specification Task Force have provided ample opportunity for public comment regarding this revision. Therefore, the staff views the removal of Appendix B as a neutral action, for which further public comments are unnecessary. For that reason, the staff chose not to issue this revision as a draft guide for public comment before publishing this Revision 1 of Regulatory Guide 1.196. Nonetheless, the NRC staff encourages and welcomes comments and suggestions in connection with improvements to published regulatory guides, as well as items for inclusion in regulatory guides that are currently being developed.

E7–2088 Filed 2–7–07; 8:45 am] BILLING CODE 7590–01–P NUCLEAR REGULATORY COMMISSION Final Regulatory Guide: Issuance, Availability The U.S. Nuclear Regulatory Commission (NRC) has issued a revision to an existing guide in the agency’s Regulatory Guide Series. This series has been developed to describe and make available to the public such information as methods that are acceptable to the NRC staff for implementing specific parts of the NRC’s regulations, techniques that the staff uses in evaluating specific problems or postulated accidents, and data that the staff needs in its review of applications for permits and licenses. Revision 1 of Regulatory Guide 1.200, ‘‘An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for RiskInformed Activities,’’ describes one acceptable approach for determining whether the quality of a probabilistic risk assessment (PRA), in total or the parts that are used to support an application, is sufficient to provide confidence in the results, such that the PRA can be used in regulatory decisionmaking for light-water reactors. Specifically, Revision 1 of Regulatory PO 00000 Frm 00053 Fmt 4703 Sfmt 4703 6011 Guide 1.200 provides guidance in four areas: (1) A minimal set of requirements of a technically acceptable PRA. (2) The NRC’s position on PRA consensus standards and industry PRA program documents. (3) Demonstration that the PRA (in total or specific parts) used in regulatory applications is of sufficient technical adequacy. (4) Documentation to support a regulatory submittal. This guidance is intended to be consistent with the NRC’s PRA Policy Statement, entitled ‘‘Use of Probabilistic Risk Assessment Methods in Nuclear Activities: Final Policy Statement,’’ which the NRC published in the Federal Register on August 16, 1995 (60 FR 42622) to encourage use of PRA in all regulatory matters. That Policy Statement states that ‘‘* * * the use of PRA technology should be increased to the extent supported by the state-of-theart in PRA methods and data and in a manner that complements the NRC’s deterministic approach.’’ Since that time, many uses have been implemented or undertaken, including modification of the NRC’s reactor safety inspection program and initiation of work to modify reactor safety regulations. Consequently, confidence in the information derived from a PRA is an important issue, in that the accuracy of the technical content must be sufficient to justify the specific results and insights that are used to support the decision under consideration. Revision 1 of Regulatory Guide 1.200 is also intended to be consistent with the more detailed guidance in Regulatory Guide 1.174, ‘‘An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on PlantSpecific Changes to the Licensing Basis,’’ which the NRC issued in November 2002. In addition, Revision 1 of Regulatory Guide 1.200 is intended to reflect and endorse (with certain objections) the following guidance provided by the American Society of Mechanical Engineers (ASME) and the Nuclear Energy Institute (NEI): • ASME RA–S–2002, ‘‘Standard for Probabilistic Risk Assessment for Nuclear Power Plant Applications,’’ dated April 5, 2002. • ASME RA–Sa7–2003, ‘‘Standard for Probabilistic Risk Assessment for Nuclear Power Plant Applications,’’ Addendum A to ASME RA–S–2002, dated December 5, 2003. • ASME RA–Sb–2005, ‘‘Standard for Probabilistic Risk Assessment for Nuclear Power Plant Applications,’’ E:\FR\FM\08FEN1.SGM 08FEN1 jlentini on PROD1PC65 with NOTICES 6012 Federal Register / Vol. 72, No. 26 / Thursday, February 8, 2007 / Notices Addendum B to ASME RA–S–2002, dated December 30, 2005. • NEI–00–02, ‘‘Probabilistic Risk Assessment Peer Review Process Guidance,’’ Revision A3, dated March 20, 2000, with its supplemental guidance on industry self-assessment, dated August 16, 2002, Revision 1, dated May 19, 2006, and an update to Revision 1 dated November 15, 2006. • NEI–05–04, ‘‘Process for Performing Follow-on PRA Peer Reviews Using the ASME PRA Standard,’’ dated January 2005. When used in support of an application, this regulatory guide will obviate the need for an in-depth review of the base PRA by NRC reviewers, allowing them to focus their review on key assumptions and areas identified by peer reviewers as being of concern and relevant to the application. Consequently, this guide will provide for a more focused and consistent review process. In this regulatory guide, as in Regulatory Guide 1.174, the quality of a PRA analysis used to support an application is measured in terms of its appropriateness with respect to scope, level of detail, and technical acceptability. This regulatory guide was issued for trial use in February of 2004, and five trial applications were conducted. The staff subsequently revised Regulatory Guide 1.200 to incorporate the lessons learned from those pilot applications. The NRC solicited public comment on this guidance by publishing a Federal Register notice (71 FR 54530) concerning Draft Regulatory Guide DG– 1161.

Final Regulatory Guide: Issuance, Availability

    The U.S. Nuclear Regulatory Commission (NRC) has issued a revision 
to an existing guide in the agency's Regulatory Guide Series. This 
series has been developed to describe and make available to the public 
such information as methods that are acceptable to the NRC staff for 
implementing specific parts of the NRC's regulations, techniques that 
the staff uses in evaluating specific problems or postulated accidents, 
and data that the staff needs in its review of applications for permits

program documents.
    (3) Demonstration that the PRA (in total or specific parts) used in
