c equipment, train, and system performance and relevant industry operational experience. As noted in Element 1.1 of Table A-1 in Appendix A to Regulatory Guide 1.200, special emphasis should be placed on PRA modeling of novel and passive features in the design, as well as addressing issues related to those features, such as digital instrumentation and control, explosive (squib) valves, and the issue of T-H uncertainties.5 The staff should confirm that the assumptions made in the applicant’s PRA during design development/certification, in which a specific site may not have been identified or all aspects of the design (e.g., balance of plant) may not have been fully developed, are identified in the DC application and either remain valid or are adequately addressed within the COL application. In addition, a DC and COL applicant may request NRC approval to implement one or more risk-informed applications. The applicant's submission and staff review of these risk-informed applications follow specific regulatory guidance, approved topical reports, and SRP sections. For example, if an applicant requests to implement a risk-informed inservice inspection program concurrent with its COL application, the application should address the guidance provided in Regulatory Guide 1.178, following a specific methodology contained in identified approved topical reports and approved industry code cases, and SRP Section 3.9.8 will guide the staff review of this program. Chapter 19 of the applicant's FSAR should identify this risk-informed application, with a cross-reference to Section 3.9.8 of the applicant's FSAR, which should describe the applicant's risk-informed inservice inspection program.
