SRP 19-40 APPENDIX A GUIDANCE FOR A FOCUSED-SCOPE APPLICATION-SPECIFIC PRA REVIEW As stated in Section 111.2.2.4 of this SRP chapter and in Section 2.2.3 of RG 1.174, PRAs that are used in risk-informed submittals to determine risk significance or risk impact should be shown to be of adequate quality. In risk-informed regulation (RIR), licensee submittals are expected to utilize an integrated process which combines risk insights from a PRA, together with insights from traditional engineering analyses, supported by performance monitoring and feedback. The quality of the PRA required to support this process is commensurate with the roles the risk insights play in the final decisionmaking. Staff evaluation of a licensee's risk-informed application submittal is
