omýised. Data from similar plants will be used if needed. In addition to the tracking of performance of SSCs affected by the application, the performance monitoring process also includes tracking the performance of SSCs which support the underlying basis for the decisionmaking. SRP 19-38 Licensee Submittal The submittal includes sufficient information to support conclusions regarding the acceptability of the proposed change. The appropriate regulatory action was requested. In addition, pertinent information on the LB change will be included in the safety analysis report, technical specifications, or license conditions, as necessary. The licensee has appropriately committed to the important programmatic and performance assumptions in the PRA and engineering analyses which served as the basis of the LB change. These include compensatory actions used to justify the change and any new regulatory requirements for high risk significant SSCs not otherwise subject to existing requirements, commensurate with their risk significance. These commitments are reflected in revisions to the safety analysis report and/or technical specifications, or the staff has imposed appropriate licensee conditions. V. IMPLEMENTATION The preceding material is intended to provide guidance to applicants and licensees regarding the NRC staff's plans for using this SRP chapter for reviews of applications involving risk-informed changes to the plant's design, operations and other activities that require NRC approval. Except in those cases in which the applicant or licensee proposes an acceptable alternative method for demonstrating that a proposed LB change is acceptable, the method described herein will be used by the staff in its evaluation of such changes.
