and 8 or Appendix 7.1-C item 11 and 24. • System testing and inoperable surveillance — See Appendix 7.1-B items 10 and 11 or Appendix 7.1-C item 12, 13, and 27. • Use of digital systems — See Appendix 7.0-A. • Interlocks to prevent overpressurization of low pressure systems — See BTP HICB-1. • Interlocks to prevent overpressure of the primary coolant system during low-temperature operations of the reactor vessel — See BTP RSB 5-2. • Interlocks for ECCS accumulator valves — See BTP HICB-2. • Interlocks required to isolate safety systems from non-safety systems and interlocks required to preclude inadvertent inter-ties between redundant or diverse safety systems. In each safety review, the Staff should determine the elements of the design that require additional review emphasis. Typical reasons for such a non-uniform emphasis are the introduction of new design features or the Rev. 4 — June 1997 SRP 7.6-5 utilization in the design of features previously reviewed and found acceptable. However, in all cases, the review must be sufficient to conclude conformance to the acceptance criteria, i.e., the requirements of the Code of Federal Regulations. IV. Evaluation Findings The Staff verifies that sufficient information has been provided and the review supports the following conclusions as stated in the SER: 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 (GDC) 1, 2, 4, 10, 13, 15, 16, 19, 24, 28, 33-35, 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 concluded that the applicant/licensee adequately identified the guidelines applicable to these systems and has properly classified them. Based upon the review of the system
