Content:
spent fuel storage pool, and containment of radioactive materials. Portions of fluid systems that provide cooling or heating, sealing, lubrication, fuel, motive power, isolation, flood protection, or leakage detection necessary to support accomplishment of any of the above functions are also considered important to safety. The applicant’s FSAR classification tables typically do not include safety functions for individual components, and additional design basis information defining the safety function used to establish the quality group classification may be needed. Nuclear Energy Institute (NEI) 97-04, “Design Bases Program Guidelines,” Appendix B, referenced in RG 1.186, “Guidance and Examples for Identifying 10 CFR 50.2 Design 3.2.2-7 Revision 3 – July 2016 Bases”, and may be used to define design basis information regarding the specific safety function in the FSAR. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. For DCs, Tier 1 information is derived from Tier 2. Consequently, any design information presented in Tier 1 also should be in the appropriate Tier 2 sections. The staff assigned to the review of quality group classification has primary review responsibility of information included in application Section 3.2.2 concerning pressure-retaining systems and their supports. The staff assists in reviews of such systems to ensure compliance with GDC 1 and coordinates the overall review with staff reviewing other SRP sections to ensure that the applicant has appropriately classified fluid systems and components important to safety using an acceptable
