as a limited high-pressure reactor coolant makeup system with flow rates sufficient to meet the criteria for small breaks in the reactor coolant pressure boundary without ac power. The RWCU/SDC system and other engineered safety features (ADS, PCCS, and GDCS) back up the ICS. Compliance with GDC 33 assures that specified acceptable fuel design limits are not exceeded as a result of reactor coolant pressure boundary leakage, rupture of small piping, or other small components that are part of the boundary. 6. GDC 34 establishes requirements for a system to transfer fission product decay heat and other residual heat from the reactor core. The ICS provides the capability for DHR. Compliance with GDC 34 precludes fuel damage or reactor coolant pressure boundary overpressurization in the event of anticipated operational occurrences that would adversely affect functions of systems that provide normal heat removal from the reactor core. 5.4.13-10 March 2007 7. GDC 35 establishes requirements to provide abundant emergency core cooling following any loss of coolant to prevent fuel damage that could interfere with continued effective core cooling and to limit clad metal-water reactions to negligible amounts. The ICS provides limited additional water inventory and DHR capability following reactor shutdown and isolation. Compliance with GDC 34 precludes fuel damage in the event of anticipated operational occurrences that would adversely affect functions of systems that provide normal heat removal from the reactor core. 8. GDC 36 requires the ECCS to be designed to permit appropriate inspection of important components. The ICS is an ECCS and therefore must be designed in a manner to permit inspection of components to assure the integrity and capability of the system. 9. GDC 37 establishes requirements for the ECCS to be designed to permit appropriate periodic pressure and functional testing. The ICS is an ECCS and therefore must be designed to permit pressure and functional
