ilure criterion on a system basis, and operability from onsite and offsite electrical power as required by GDC 34, 35, 38, and 41. 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 7.3-6 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 review of the instrumentation and control aspects of the engineered safety feature (ESF) systems includes the engineered safety features actuation systems (ESFAS) and the ESF control systems. The ESFAS detects a plant condition requiring the operation of an ESF system and/or essential auxiliary supporting (EAS) system and initiates operation of these systems. The ESF control systems regulate the operation of the ESF systems following automatic initiation by the protection system or manual initiation by the plant operator. The NRC staff concludes that the design of the ESFAS is acceptable and meets the relevant requirements of General Design Criteria (GDC) 1, 2, 4, 13, 19-24, 29, 34, 35, 38, and 41 and 10 CFR 50.34(f), 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, industry standards and branch technical positions applicable to these systems. The Staff concludes that the applicant/licensee acceptably identified the guidelines applicable to these systems. Based upon the review of the system design for conformance to the guidelines, the Staff concludes that the systems conform to the guidelines
