capability to assure that (1) specified acceptable fuel design limits and design conditions of the reactor coolant pressure boundary are not exceeded as a result of anticipated operational occurrences and (2) the core is cooled and containment integrity and other vital functions are maintained in the event of postulated accidents and possible loss of power generated by the nuclear power plant. 5. With respect to GDC 33, the application should demonstrate that the system can supply reactor coolant makeup for protection against small breaks in the reactor coolant pressure boundary and in the event that either onsite or offsite ac power is unavailable. 6. With respect to GDC 34, the application should demonstrate that the system can transfer fission product decay heat and other residual heat from the reactor core at a rate such that specified acceptable fuel design limits and the design pressure of the reactor coolant pressure boundary are not exceeded. The application should demonstrate that the ICS provides the capability for decay heat removal, and that component redundancy, leak detection and isolation capabilities are provided. ICS operation should be assured with a single active failure including electric power. 7. With respect to GDC 35, the application should demonstrate that the system design is capable of providing abundant emergency core cooling following any loss of coolant such that: (1) fuel and clad damage that could interface with continued effective core cooling is prevented and, (2) clad metal-water reaction is limited to negligible amounts. The application should demonstrate that the ICS provides water inventory and DHR capability following reactor shutdown, and that component redundancy, leak detection and isolation capabilities are provided. ICS operation 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
