emely high probability of accomplishing its function. The reactor protection or ESF system activates initiation of the RCIC system during appropriate anticipated operational occurrences. The design of 5.4.6-8 Revision 2 - March 2007 the RCIC interface with this system must continue to provide an extremely high probability of accomplishing its safety functions. Compliance with GDC 29 provides reasonable assurance that specified acceptable fuel design limits are not exceeded as a result of anticipated operational occurrences. 4. GDC 33 specifies requirements for a system to 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. The RCIC system is designed as a 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. Compliance with GDC 33 ensures that specified acceptable fuel design limits are not exceeded because of reactor coolant pressure boundary leakage or the rupture of small piping or other small components that are part of the boundary. 5. GDC 34 requires a system to 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 conditions of the reactor coolant pressure boundary are not exceeded. The RCIC system provides the capability for decay heat removal. Compliance with GDC 34 precludes fuel damage or reactor coolant pressure boundary overpressurization in the event of anticipated operational occurrences that would adversely affect the functions of systems that provide normal heat removal from the reactor core. 6. GDC 54 requires that piping systems penetrating primary reactor containment shall be provided with leak detection, isolation, and containment capabilities having redundancy, reliability, and performance capabilities that
