lude provisions to ensure that the licensee has proposed an implementation and monitoring process that is adequate to (in part) account for uncertainties regarding plant performance under the proposed change. • Element 4 - Document Evaluations and Submit Request: Reviewers should ensure that the submittal includes sufficient information to support conclusions regarding the acceptability of the proposed change, and that the archival documentation of the evaluation process and findings is maintained and available for staff audit and review. Reviewers should also ensure that the licensee has requested the appropriate regulatory action (for example, a license amendment, an exemption, or a change to technical specifications). Where appropriate, reviewers should ensure that the submittal has documented any licensee-proposed enhancements to regulatory requirements (e.g., high risk significant SSCs not currently subject to regulatory control may be subject to requirements commensurate with their risk significance). Finally, reviewers should ensure that LB changes are appropriately included in an updated safety analysis report, as necessary. Application-Specific Reviews This Chapter 19 of the SRP is intended to provide guidance for reviewing applications in risk-informed regulation where numerical values of risk indices play a relatively large role in the decisionmaking process and where a broad set of scenarios and plant operating modes may be affected. Where it is determined that an application could justify a review that is less than the full scope described in this document, reviewers should choose the relevant and applicable parts of this SRP chapter for guidance. The necessary sophistication of the review of the PRA, its supporting analyses, and its results depend on the contribution the risk assessment provides to the integrated decisionmaking. Application-specific SRP chapters (where available) provide additional guidance in this area. II. ACCEPTANCE CRITERIA This
