entify SSCs with high risk significance that are not currently subject to regulatory requirements, or are subject to a level of regulation that is not commensurate with their risk significance, or are voluntary actions that are key to decisionmaking. In addition, licensees are expected to propose LB changes that will subject such SSCs or voluntary actions to the appropriate level of attention, consistent with their significance. Application-specific regulatory guides set forth specific information on the staff’s expectations on this issue. Reviewers should ensure that this application-specific guidance is followed. If there is no guidance, reviewers should determine whether any commitments for enhanced requirements/controls are appropriate for such SSCs or voluntary actions, and ensure that those commitments are reflected in the licensing basis. III.4.1 Update of the Safety Analysis Report Reviewers should ensure that the proposed changes, when approved by the staff, will be appropriately included in future updates to the licensee’s safety analysis report. In addition, the licensee should identify important assumptions (including SSC functional capabilities and performance attributes) that play a key role in supporting the acceptability of the LB change. Since the continued satisfaction of these assumptions is necessary to maintain the validity of the safety evaluation, reviewers should verify that such assumptions are reflected by licensee commitments that are incorporated into the safety analysis report. Reviewers should also verify that the licensee has submitted revised FSAR pages as necessary. This revision should include all the programmatic activities, performance monitoring aspects, and SSC functional performance and availability attributes which form the basis of the request. This material should also identify the SSCs for which performance should be verified (including non-safety-related SSCs for which performance and reliability provide part of the
