tionships between the change and the above SSCs, operator actions, and plant operational characteristics • mapping of the cause-effect relationships onto PRA model elements • identification of the PRA results that will be used in the decision making • the scope of risk contributors needed to support the decision The documents also address issues related to limitations in scope of the PRA. However the PRA results are used, and whatever role they play in the decision making, the PRA analysis must be of sufficient quality to support that role. The existing SRP sections give guidance on assessing the use ofthe PRA results, but do not give specific guidance on assessing the adequacy of the base PRA. Regulatory Guide 1.200 and this SRP section are intended to fill that gap. 1 In this SRP, a part of a PRA can be understood as being equivalent to that piece of the analysis for which an applicable PRA standard identifies a supporting level requirement. 19.1-4 Revision 2 - June 2007 This SRP section provides guidance to the NRC staff on determining the scope of review of the elements of a PRA analysis used to support a specific regulatory application, based on information provided by the licensee on the results of a comparison with an industry PRA standard or the results of a peer review performed in accordance with an industry approved peer review process. This SRP section is intended to be used in conjunction with an application-specific SRP section such as SRP Section 19.0, Section 19.2, Section 16.1, Section 3.9.7, or Section 3.9.8, which focus on the appropriate use of the PRA results in an integrated decision-making process. This SRP section may also be used to support novel applications in which the licensee is expected to identify how the PRA results are used to provide information to the decision makers. This SRP section does not focus on the decision-making process itself, which is addressed in the application-specific SRP sections. General This SRP is
