e requirements for system performance to preclude an unacceptable release of 9.4.3-8 Revision 3 - March 2007 contaminants to the environment during normal, abnormal, and accident conditions, the staff concludes that the design of the ARAVS and supporting systems is in conformance with NRC regulations as set forth in GDC 2, “Design Bases for Protection Against Natural Phenomena,” GDC 5, “Sharing of Structures, Systems, and Components,” and GDC 60, “Control of Releases of Radioactive Materials to the Environment.” This conclusion is based on the following findings: 1. The applicant has met the requirements of GDC 2, “Design Bases for Protection Against Natural Phenomena,” with respect to the system being capable of withstanding the effects of earthquake by meeting the guidelines of RG 1.29, “Seismic Design Classification,” Position C.1 for safety-related portions of the system and Position C.2 for nonsafety-related portions of the system. 2. The applicant has met the requirements of GDC 5, “Sharing of Structures, Systems, and Components Important to Safety to Perform Required Safety Function,” with respect to capability of shared systems and components important to safety to perform required safety functions. 3. The applicant has met the requirements of General Design Criterion 60, “Control of Releases of Radioactive Materials to the Environment,” with respect to the capability of the system to suitably control release of gaseous radioactive effluents to the environment by meeting the guidelines of RGs 1.52 and 1.140 as related to design, inspection, testing, and maintenance criteria for post-accident and normal atmosphere cleanup systems, ventilation exhaust systems, air filtration, and adsorption units of light-water-cooled nuclear power plants. For RG 1.52 rev 2, the applicable regulatory position is C.2. For RG 1.52 rev 3, the applicable regulatory position is C.3. For RG 1.140 rev 1, the applicable regulatory positions are C.1 and C.2.
