NEW REACTORS REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of the applicant’s probabilistic risk assessment 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 probabilistic risk assessment (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. 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 19.0-2 Revision 3 – December 2015 (RG) 1.174, “An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis,” and RG 1.200, “An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk- Informed Activities,” and SRP Sections 19.1, “Determining the Technical Adequacy of Probabilistic Risk Assessment for Risk-Informed License Amendment Requests after Initial Fuel Load,” and Section 19.2, “Review of Risk Information Used to Support Permanent Plant Specific Changes to the Licensing Basis: General Guidance,” (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
