understand, review, and confirm the PRA results, insights, and associated analytical bases. The staff will refer to the summary reports from these audits in the SER. For instances in which additional information is needed to complete the staff’s review of the FSAR, the staff will use the RAI process. Reviewers utilizing the RAI process should make it clear to the applicant that if an RAI results in substantive change to information in the FSAR or DCD, these documents must be revised to reflect the new information. For additional information, the staff should consider the information provided in Chapter 19 of past SERs for advanced LWRs. The NRC issued the Final Safety Evaluation Report (FSER) for 2 A method used in the determination of the functional and accident sequence level of fragility. The overall fragility of a group of inputs combined using OR logic (i.e., seismic event tree nodal fault tree) is determined by the lowest (minimum) input. Conversely, the overall fragility of a group of inputs combined using AND logic (i.e., seismic event tree sequence) is determined by the highest (maximum) input. 19.0-19 Draft Revision 3 – September 2012 the DC of the Advanced Boiling-Water Reactor design (ABWR) as NUREG-1503, the FSER for the DC of the System 80+ reactor design as NUREG-1462, the FSER for the DC of the AP600 design as NUREG-1512, and the FSER for the DC of the AP1000 design as NUREG-1793. The staff issued the FSER for the DC of the Economic, Simplified, Boiling-Water Reactor (ESBWR) design by letter dated March 9, 2011. It is available at ADAMS Accession No. ML103470210. In addition, although it relates to the staff review of license applications requesting risk-informed changes to an applicant’s licensing bases, Section A.11 of SRP Section 19.2 lists documents that the staff could use as reference or background material during the review process. The bibliography lists documents by category, covering desirable PRA attributes, review of the PRA,
