on 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.45 IV. EVALUATION FINDINGS DRAFT Rev. 3 - April 1996 9.2.5-10 The reviewer verifies that sufficient information has been provided and the review supports conclusions of the following type, to be included in the staff's safety evaluation report (SER):46 The ultimate heat sink review included the size, type of cooling supply (e.g., large body of water, ocean, lake, natural or manmade reservoir, river, pond, or cooling tower), and makeup sources to the ultimate heat sink. The review has determined the adequacy of the applicant's proposed design criteria, design bases and safety classification for the ultimate heat sink and the requirements for delivering cooling water for a safe shutdown during normal and accident conditions. The UHS and its supporting systems meet seismic Category I, Quality Group C requirements. The staff concludes that the design of the ultimate heat sink is acceptable and meets the requirements of General Design Criteria 2, 5, 44, 45, and 46. This conclusion is based on the following: 1. The applicant has met the requirements of General Design Criterion 2 with respect to being capable of withstanding the effects of earthquakesnatural phenomena such as earthquakes, tornadoes, tornado missiles, hurricanes, and floods. Acceptance is based on meeting the guidance of Regulatory Guide 1.29, 47 Position C.1, and Regulatory Guide 1.27, Positions C.2 and C.3. In addition, 48 for a UHS formed by a dam or a system of dikes or levees, acceptance is also based on the UHS being designed in accordance
