mSv (0.5 rem) to the whole body or its equivalent to any part of the body. 44 Meeting the requirement of GDC 2 provides assurance that the SFPAVS will not fail to operate as designed, thus protecting against the uncontrolled release of airborne radioactive materials in the event of a design basis earthquake.45 2. Compliance with GDC 5 requires that structures, systems, and components important to safety shall not be shared among nuclear power units unless it can be shown that such sharing will not significantly impair their ability to perform their safety functions, including, in the event of an accident in one unit, an orderly shutdown and cooldown of the remaining units. DRAFT Rev. 3 - April 1996 9.4.2-6 With regard to the SFPAVS, GDC 5 requires that the component parts of the SFPAVS be essentially independent in order to ensure that an accident in one unit of a multiple-unit facility will not propagate to other units. Therefore the SFPAVS needs to be designed to accommodate loss of services from any one unit without affecting operation of the overall system. Meeting the requirements of GDC 5 provides assurance that a failure or accident in one unit will not affect additional units of a multiple-unit site.46 3. Compliance with GDC 60 requires that provisions be included in the nuclear power unit design to ensure suitable controls on the release of radioactive materials in gaseous effluents during normal reactor operation, including anticipated operational occurrences. During transfer or movement of spent fuel in the fuel storage pool, damage to the fuel cladding could result in potential releases of radioactive gases and aerosols to the atmosphere. Thus, GDC 60 is applicable to spent fuel storage areas. Atmosphere cleanup systems are included in the design of SFPAVS to reduce the quantities of radioactive materials in gaseous effluents released to the environment. Regulatory Guides 1.140 and 1.52 offer design, testing, and maintenance criteria acceptable to the
