he FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action 9.2.5-8 Revision 3 - March 2007 items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). 6. For review of both DC and COL applications, SRP Section 14.3 should be followed for the review of ITAAC. The review of ITAAC cannot be completed until after the completion of this section. IV. EVALUATION FINDINGS The reviewer verifies that the applicant has provided sufficient information and that the review and calculations (if applicable) support conclusions of the following type to be included in the staff’s safety evaluation report. The reviewer also states the bases for those conclusions. The UHS 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. The review has determined the adequacy of the applicant’s proposed UHS design criteria, design bases, and safety classification and the requirements for cooling water delivery 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 UHS design is acceptable and meets the requirements of GDCs 2, 5, 44, 45, and 46. This conclusion is based on the following findings: 1. The applicant meets GDC 2 requirements for capability to withstand the effects of natural phenomena like earthquakes, tornadoes, tornado missiles, hurricanes, and floods. Acceptance is based on RG 1.27, Positions C.2 and C.3. 2. The applicant
