tion should be assured with a single active failure including electric power. 8. With respect to GDC 36, the application should demonstrate that the ECCS is designed in a manner permitting appropriate inspection of important components, to assure the readiness, integrity, and capability of the system. 9. With respect to GDC 37, the application should demonstrate that the ICS is designed to permit appropriate periodic pressure and functional testing to assure: (1) structural and leaktight integrity of its components, (2) the operability and performance of the active components of the system, and (3) the operability of the system as a whole and, under conditions as close to design as practical, the performance of the full operational sequence that brings the system into operation, including operation of applicable portions of the protection system, the transfer between normal and emergency power sources, and the operation of the associated cooling water system. 5.4.13-8 March 2007 10. With respect to GDC 54, the application should demonstrate that piping systems penetrating primary containment are provided with leak detection, isolation, and containment capabilities having redundancy, reliability, and performance capabilities that reflect the importance to safety of isolating these piping systems. An acceptable design of such piping systems must have the capability to test periodically the operability of the isolation valves and associated apparatus and to determine whether valve leakage is within acceptable limits. 11. With respect to 10 CFR 50.46, the application should demonstrate that an acceptable evaluation model is used so that the cooling performance is sufficient to assure that the most severe postulated LOCA is calculated. The application should demonstrate that: 1) the maximum fuel element cladding temperature shall not exceed 2200EF, 2) the maximum total cladding oxidation shall nowhere exceed 0.17 times the total cladding thickness before oxidation, 3)
