acceptable if the VWS and its components will continue to perform their required safety functions, assuming a single active failure or a moderate-energy line crack as defined in BTP 3-3 and to seismic Category I, Quality Group C, and ASME Section III, Class 3 requirements concurrent with the LOOP. In addition, the information will be considered acceptable based on appropriate application of Institute of Electrical and Electronics Engineers (IEEE) Standard 603, as endorsed by RG 1.153, “Criteria for Safety Systems,” and appropriate application of RG 1.155, “Station Blackout,” Regulatory Position C.3.3.4. Note: RTNSS B SSCs may provide core cooling and heat transfer functions in the post-72 hour period. RTNSS C may provide for defense-in-depth cooling and heat transfer functions in order to meet NRC safety goal guidelines. 6. Cooling Water System Inspection. Information that addresses the requirements of GDC 45 regarding the inspection of cooling water systems will be considered acceptable if the periodic inspection of important VWS components ensures system integrity and capability to perform design safety functions. 7. Cooling Water System Testing. Information that addresses the requirements of GDC 46 regarding the testing of cooling water systems will be considered acceptable if periodic system pressure and function testing of the VWS will ensure the leak tight integrity and operability of its components, as well as the operability of the system as a whole, at conditions as close to the design basis as practical. System operability should also be monitored through Technical Specifications in Chapter 16 of the safety analysis report. 9.2.7-12 Draft Revision 0 – July 2014 8. Minimization of contamination. Information that address the requirements of 10 CFR 20.1406 regarding minimization of contamination to the facility and the environment, and designs to facilitate eventual decommissioning, will be considered acceptable if the design identifies provisions
