conditions, keeping personnel exposures to radiation within acceptable limits. 2. GDC 5 requires that SSCs important to safety not be shared among nuclear power units unless such sharing can be shown not to significantly impair their ability to perform safety functions, including, in an accident in one unit, an orderly shutdown and cooldown of the remaining units. GDC 5 requirements ensure LLHS design for essentially independent LLHS SSCs in LLHS shared for use in multiple-unit plants. The shared use in multiple-unit plants, therefore, will not affect the LLHS safety function significantly. SRP Section 9.1.4 provides guidance to meet these requirements. Compliance with GDC 5 provides assurance that the LLHS and its SSCs will continue to perform their required safety functions when the LLHS is shared among nuclear power units and that safe handling of fuel will not be jeopardized. 3. GDC 61 requires that fuel storage and handling, radioactive waste, and other systems that may contain radioactive materials be designed for adequate safety under normal and postulated-accident conditions. GDC 61 requires LLHS design for safe fuel handling and storage under normal and accident conditions. SRP Section 9.1.4 addresses handling of fuel and spent fuel, which, if dropped, mishandled, or damaged, could cause releases of radioactive materials or unacceptable personnel radiation exposures. ANSI/ANS 57.1-1992 provides guidance for meeting these requirements. In addition, SRP Section 9.1.4 provides guidance to address the GDC 61 requirement to provide suitable radiological shielding in the refueling cavity (i.e., retaining water in the refueling cavity), residual heat removal capability, and prevention of a significant reduction in coolant inventory under accident conditions. 9.1.4-6 Draft Revision 4 – June 2013 Compliance with GDC 61 provides reasonable assurance that releases of radioactive materials and unacceptable personnel radiation exposures from damage to irradiated fuel
