s, and (c) limitations on opening and closing sequences and-seal-ins for manual opera- tion of the isolation valves to preclude introducing water slugs into the line. The turbine exhaust line features include sloped lines and vacuum breakers. IV. EVALUATION FINDINGS The reviewer verifies that the SAR contains sufficient information and his review supports the following kinds of statements and conclusions, which should be included in the staff's safety evaluation report: The reactor core isolation cooling (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 engineered safety features (HPCS or HPCI) 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, his analysis of the adequacy of the criteria and bases, and the 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 General Design Criteria 4, 5, 29, 33, 34 and 54. This conclusion is based on the following: 1. The applicant has met the requirements of (cite Reg.) with respect to (state limits of review) by: (Use one or more of the following as applicable) a. meeting the regulatory position in Regulatory Guide b. providing and meeting an alternative method to the regulatory position in Regulatory Guide , that the staff has reviewed and found to be acceptable, c. meeting the regulatory position in BTP_ d. The calculational method used by the applicant for (state) has been previously reviewed by the staff and found acceptable; the staff has reviewed the key parameters in this
