n, 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). 3. 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 following for those conclusions: 1. The NRC staff concludes that the design of the interlock systems is established in accordance with its safety function, is acceptable, and meets the relevant requirements of GDC 1, 2, 4, 10, 13, 15, 16, 19, 24, 28, 33, 34, 35, 38, 41 and 44, 10 CFR 50.55a(a)(1), and 10 CFR 50.55a(h). The staff conducted a review of these systems for conformance to the guidelines in the regulatory guides and industry codes and standards applicable to these systems. The staff concludes that the applicant/licensee adequately identified the guidelines applicable to these systems and has properly classified them. Based upon the review of the system design for conformance to the guidelines, the staff finds that there is reasonable assurance that the systems fully conform to the guidelines applicable to these systems. Therefore the staff finds that the requirements of GDC 1, 15, 16, 33, 34, 35, 38, 41, and 44, and 10 CFR 50.55a(a)(1) have been met. 7.6-7 Revision 5 - March 2007 Based on the review of interlock system functions, the staff concludes that appropriate interlocks are provided to maintain an appropriate design margin to assure that acceptable fuel design limits are not exceeded during any condition of normal operation, including the effects of anticipated operational
