Content:
e if the design provisions presented in Generic Letter (GL) 96-06, ““Assurance of Equipment Operability And 9.2.7-9 Revision 0 – September 2015 Containment Integrity During Design-Basis Accident Conditions,” and GL 96-06, ”Assurance of Equipment Operability And Containment Integrity During Design-Basis Accident Conditions,” Supplement 1 are appropriately addressed. 4. Sharing of Structures, Systems, and Components. Information that addresses the requirements of GDC 5 regarding the capability of shared systems and components important to safety to perform required safety functions will be considered acceptable if the use of the CWS in multiple unit plants during an accident in one unit does not significantly affect the capability to conduct a safe and orderly shutdown and cool down in the unaffected unit(s). 5. Cooling Water System. Information that addresses the requirements of GDC 44 regarding consideration of the cooling water system will be considered acceptable if the CWS 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 American Society of Civil Engineers (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 (std) 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. 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 CWS components ensures system integrity and capability to perform design safety functions. 7. Cooling Water System Testing. Information that
