es housing the system and the system itself being capable of withstanding the effects of external missiles and internally generated missiles, pipe whip, and jet impingement forces associated with pipe breaks. 3. GDC 5, as related to the capability of shared systems and components important to safety to perform required safety functions. 4. GDC 19, as related to the design capability of system instrumentation and controls for prompt hot shutdown of the reactor and potential capability for subsequent cold shutdown. 5. GDC 34 and 44, to assure: A. Capability to transfer heat loads from the reactor system to a heat sink under both normal operating and accident conditions. B. Redundancy of components for performance of the safety function under accident conditions, assuming a single active component failure (perhaps coincident with the loss of offsite power for certain events). 10.4.9-6 Revision 3 - March 2007 C. Capability to isolate components, subsystems, or piping if required to maintain system safety function. 6. GDC 45, as related to design provisions made to permit periodic in service inspection of system components and equipment. 7. GDC 46, as related to design provisions made to permit appropriate functional testing of the system and components to assure structural integrity and leak-tightness, operability and performance of active components, and capability of the integrated system to function as intended during normal, shutdown, and accident conditions. 8. 10 CFR 50.62, as related to the design provisions for automatic initiation of the AFWS in an ATWS. 9. 10 CFR 50.63, as related to the design provisions for withstanding and recovering from a station blackout, including an acceptable degree of independence from the ac power system and the capability for removal of decay heat at an appropriate rate for an appropriate duration. 10. 10 CFR 52.47(b)(1), which requires that a DC application contain the proposed inspections, tests, analyses, and acceptance criteria
