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. (For completeness, this evaluation finding includes the RSB review effort described in SRP Section 15.6.5.) The emergency core cooling system (ECCS) includes the piping, valves, pumps, heat exchangers, instrumentation, and controls used to transfer heat from the core following a loss-of-coolant accident. The scope of review of the ECCS for the plant included piping and instrumentation diagrams, equipment layout drawings, failure modes and effects analyses, and design specifications for essential components. The review has included the applicant's proposed 6.3-10 Rev. 2 - April 1984 design criteria and design bases for the ECCS and the manner in which the design conforms to these criteria and bases. The staff concludes that the design of the Emergency Core Cooling System is acceptable and meets the requirements of General Design Criteria 2, 4, 5, 17, J 27, 35, 36, and 37. This conclusion is based on the following: (1) The applicant has met the requirements of GOC 2 with regard to the seismic design of nonsafety systems or portions thereof which could have an adverse effect on ECCS by meeting position C.2 of Regulatory Guide 1.29. (2) The applicant has met the requirements of GOC 4 as related to dynamic effects associated with flow instabilities and loads (e.g., water hammer). l (3) The applicant has met the requirements of GDC 5 with respect to sharing of structures, systems, and components by demonstrating that such sharing does not significantly impair the
