CS accumulator valves - See SRP BTP 7-2. I. Interlocks required to isolate safety systems from nonsafety systems. J. Interlocks required to preclude inadvertent inter-ties between redundant or diverse safety systems. 2. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document. The reviewer should also consider the appropriateness of identified COL action 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 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 (SER). 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 General Design Criteria 1, 2, 4, 10, 13, 15, 16, 19, 24, 28, 33, 34, 35, 38, 41 and 44, 7.6-7 Draft Revision 6 – August 2015 10 CFR 50.54(jj) and 50.55(i), and 10 CFR 50.55a(h). The staff conducted a review of these systems for conformance to the
