t to provide reasonable assurance that, if the inspections, tests, and analyses are performed and the acceptance criteria met, the facility has been constructed and will operate in conformity with the combined license, the provisions of the Atomic Energy Act, and the NRC's regulations. SRP Acceptance Criteria Specific SRP acceptance criteria acceptable to meet the relevant requirements of the NRC’s regulations identified above are as follows for the review described in this SRP section. The SRP is not a substitute for the NRC’s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 1. The general objective of the review is to determine that the RCIC system-in conjunction with the HPCS (or HPCI) system, the safety and relief valves (SRVs), and the suppression pool cooling mode of the residual heat removal (RHR) system-meets the requirements of GDC 34 by providing the capability for decay heat removal to enable complete shutdown of the reactor under conditions requiring its use. The system must maintain the reactor water inventory above the top of the active fuel until the reactor is sufficiently depressurized to permit operation of the low-pressure cooling systems. The RCIC system-in conjunction with the HPCS (or HPCI) system, SRVs, and suppression pool cooling mode of the RHR system-must be capable of removing fission product decay heat and other residual heat from the reactor core following shutdown thus precluding fuel damage or reactor coolant pressure boundary overpressurization. Because the RCIC system, in conjunction with the HPCS (or HPCI) system, provides makeup inventory in some modes of RHR, these systems should jointly meet
