EVALUATION FOR NEW REACTORS REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of the applicant’s probabilistic risk assessment (PRA) Organization responsible for the review of severe accident design features Secondary - Organization responsible for the review of structural engineering Technical organizations identified in the Review Interface section of this plan may be consulted, as needed I. AREAS OF REVIEW This section of the Standard Review Plan (SRP) pertains to the staff review of the design-specific PRA for a design certification (DC) and plant-specific PRA for a combined license (COL) application, respectively. This SRP section also pertains to the staff review of the applicant’s deterministic evaluation of design features for the prevention or mitigation of severe accidents. 19.0-2 Draft Revision 3 – September 2012 Subsequent to COL issuance, the staff may review the applicant's PRA (or portions thereof) in the context of licensing actions, following the guidance provided in Regulatory Guide (RG) 1.174 and RG 1.200, and SRP Sections 19.1 and 19.2 (previously SRP Chapter 19). Associated application-specific regulatory guidance and SRP sections should be consulted, while maintaining the validity of the staff findings associated with the licensing basis related to PRA and severe accidents. The purpose of the staff’s review is to ensure that the applicant has adequately addressed the Commission’s objectives regarding the appropriate way to address severe accidents and to use PRA in the design and operation of facilities under review. These objectives are outlined in RG 1.206, Section C.I.19.2 and should be addressed in Section 19.1.1 of the applicant’s Final Safety Analysis Report (FSAR). The scope of a DC review is limited to the design-specific aspects within the scope of the design certification. The design-specific PRA developed during the DC stage may not identify site-specific information (e.g., local hazards,
