Content:
rmed; accordingly, this Note should be applied only to SAR content for applications other than a CP application. g. Addition: In addition to the site information described in Section C.2 of NEI 21-07, Revision 1, the applicant in Chapter 2 of the SAR should provide additional information not developed using the LMP process, including summaries of the site-related information and analyses used to derive the design-basis hazard levels (DBHLs) documented in Chapter 6 of the SAR. The purpose of this additional information is (1) to demonstrate compliance with 10 CFR Part 100, “Reactor Site Criteria” (Ref. 25), Subpart B, “Evaluation Factors for Stationary Power Reactor Site Applications on or after January 10, 1997,” and the relevant site-related requirements of 10 CFR Part 50 and 10 CFR Part 52, and (2) to describe the site characteristics used to inform the selection of the DBHLs in the design and safety analysis. Considerations for each relevant hazard include: (1) SR SSCs must be protected from or designed to withstand the corresponding DBHL with no adverse impact on their ability to perform their required safety functions (RSFs), (2) NSRST SSCs credited in non-DBA licensing basis events (i.e., AOOs, DBEs, and BDBEs) or to establish adequate DID may need to be specially designed to withstand or be protected from the hazard (e.g., application of special treatments in accordance with NEI 18-04 and RG 1.233), and (3) NSRST SSCs relied upon to establish adequate DID for beyond design basis hazards may need to be designed with special treatment to withstand or be protected from each such hazard. Determination of these special treatments for NSRST SSC will be made by the integrated design process panel (IDPP) in accordance with NEI 18-04 and RG 1.233. The draft ARCAP ISG, DANU-ISG-2022-02, “Site Information,” (Ref. 26), contains additional guidance on one acceptable approach to determining the scope and level of detail of the site information to be provided.
