t. The reviewer also states the bases for those conclusions. The RCIC system includes the piping, valves, pumps, turbines, instrumentation, and controls used to maintain water inventory in the reactor vessel whenever it is isolated from the main feedwater system. Certain ESFs (HPCS, HPCI, or HPCF) provide a redundant backup for this function. The scope of review of the RCIC system for the _____ plant included piping and instrumentation diagrams, equipment layout drawings, and functional specifications for essential components. The review has included the applicant’s proposed design criteria and design bases for the RCIC system, its analysis of the adequacy of the criteria and bases, and conformance of the design to these criteria and bases. The staff concludes that the reactor core isolation cooling system design is acceptable and meets the requirements of GDC 4, 5, 29, 33, 34, 54 and 10 CFR 50.63. This conclusion is based on the following: 1. The applicant has met the requirements of (cite regulation) with respect to (state limits of review) by completing the following (use one or more of the following as applicable): A. Meeting the regulatory position in Regulatory Guide ________. B. Providing and using an alternative method to the regulatory position in Regulatory Guide ________, which the staff has reviewed and found acceptable. 5.4.6-13 Revision 2 - March 2007 C. Meeting the regulatory position in BTP ________. D. The applicant for (state) used a calculational method that the staff has previously reviewed and found acceptable; the staff has reviewed the key parameters in this case and found them to be suitably conservative. E. The applicant has met the requirements of (industry standard, number, and title), which the staff has reviewed and determined to be appropriate for this application. 2. Repeat the above discussion for each GDC listed. In addition, SRP Section 6.2 discusses conformance with GDC 55, 56, and 57 regarding containment isolation. Sections 3.3
