license (COL) applicants that reference a certified design, the certification will have addressed the implementation of the RTNSS process. 4. Procedures and Training. The review should determine that procedures and training conform to the guidance in Sections C.1.3, C.2, and C.3.4 of RG 1.155. Procedures and training should address all operator actions necessary to (a) restore EAC power when the EAC power system is unavailable, (b) cope with AAC or battery power on the occurrence of an SBO for the specified coping duration during all modes of plant operation, (c) restore offsite power and use of nearby power sources (which may include such items as nearby or onsite gas turbine generators, portable generators, or hydrogenerators) in the event of a loss of offsite power (LOOP), and (d) restore normal long-term core cooling/decay heat removal once power is restored. The review should determine that communication agreements and protocols between the plant and its transmission system operator provide assurance that the NPP operator will be kept aware of (a) changes in the plant switchyard and offsite power grid and (b) local power sources and transmission paths that could be made available to resupply the plant following a LOOP (Ref. 15). 5. Quality Assurance (QA) and Specifications for Non-Safety-Related Equipment. The review should determine that QA activities and specifications for non-safety-related equipment used to meet the requirements of 10 CFR 50.63 conform to the recommendations in Section C.3.5 and Appendix A to RG 1.155. The review should also determine that systems and equipment used to meet the requirements of 10 CFR 50.63 conform to the system and station equipment specification recommendations of Appendix A to RG 1.155.
