Content:
elevant NRC requirements identified in subsection II. The system description and schematic drawings presented in the SAR should be sufficiently detailed to permit judgments to be made regarding system acceptability. 1. The reviewer determines that all potential, active mechanical failures and passive electrical failures have been identified and that no single failure would incapacitate an entire system. 2. The reviewer compares the quality standards applied to the systems to the provisions of RG 1.7, Revision 3. 3. The reviewer compares the seismic design classifications of the systems to the provisions of RG 1.7, Revision 3. 6.2.5-8 Revision 3 - March 2007 4. The reviewer reviews the qualification testing of systems and components, to establish the functional capability of the equipment. 5. The reviewer reviews the provisions made in the design of the systems and the program for periodic inservice inspection and operability testing of the systems or components. The inspections are reviewed with regard to the purpose of each inspection. The operability tests that will be conducted are reviewed with regard to what each test is intended to accomplish. Judgment and experience from previous reviews are used to determine the acceptability of the inspection and test program. 6. The reveiwer reviews the proposed technical specifications, for plants at the OL or COL stage of review, for the systems used to control and monitor combustible gas and oxygen concentrations in the containment to ensure that the requirements of 10 CFR 50.44 and GDC 5, 41, 42, and 43 are met. 7. The reviewer reviews the capability to monitor system performance and control active components to be sure that control can be exercised over a system and that a malfunctioning system train or component can be isolated. The instrumentation provided for this purpose should be redundant and should enable the operator to identify the malfunctioning system train or component. 8. The reviewer reviews analyses of
