se of alternate feedwater systems and 10.4.7-8 Revision 4 - March 2007 addresses redundancy, interconnections, leak detection, and isolation capabilities to establish that containment isolation can be accomplished during accidents that occur concurrently with loss of onsite or offsite power and a single failure. Meeting the requirements of this criterion provides a level of assurance that the capability for heat removal from the reactor will be retained during normal and accident conditions, thus protecting fuel cladding from elevated temperatures. 5. GDC 45 requires that the cooling water system shall be designed to permit appropriate periodic inspection of important components (e.g., heat exchangers and piping) to ensure the integrity and capability of the system. GDC 45 applies to SRP Section 10.4.7 because the CFS provides cooling water to the reactor or steam generators and because the CFS is isolated in the event of certain accidents. This review verifies that the feedwater system design facilitates inspection. Meeting the requirements of this criterion provides a level of assurance that the CFS will be able to perform its safety function in the event of an accident. 6. GDC 46 requires that the cooling water system shall be designed to facilitate periodic pressure and functional testing that will ensure (a) the structural and leaktight integrity of cooling water system components, (b) the operability and the periodic performance of the system's active components, and (c) the operability of the system as a whole. The criterion further requires that the testing ensure, under conditions as close to design as practical, the performance of the full operational sequence that brings the system into operation for reactor shutdown and for loss-of-coolant accidents, including operation of applicable portions of the protection system and the transfer between normal and emergency power sources. GDC 46 applies to SRP 10.4.7 because the CFS provides the proper cooling water
