stem. 9.4.5-13 DRAFT Rev. 3 - April 1996 2. The applicant has met the environmental requirements of GDC 4 by appropriately addressing adverse environmental conditions and dynamic effects in the design of the system to ensure its capability for maintaining environmental conditions in essential areas served by the system within the design limits of the essential equipment important to safety located in these areas for normal, transient, or accident conditions.65 3. The applicant has met the requirements of GDC 5 with respect to capability of shared systems and components important to safety to perform required safety functions since no postulated single active failure will prevent the system from performing its safety function. 4. The applicant has met the requirements of GDC 17 as related to assuring ensuring proper functioning of the essential electric power system by meeting the guidelines of NUREG-CR/0660 as related to the accumulation of dust and particulate materials. 5. The applicant has met the requirements of GDC 60 with respect to the capability of the system to suitably control release of gaseous radioactive effluents to the environment by meeting the guidelines of Regulatory Guide 1.52, "Design, Testing and Maintenance Criteria for Atmosphere Cleanup System Air Filtration and Adsorption Units of Light-Water-Cooled Nuclear Power Plants," position C.2, and Regulatory Guide 1.140, "Design, Testing and Maintenance Criteria for Normal Ventilation Exhaust System Air Filtration and Adsorption Units of Light-Water-Cooled Nuclear Power Plants," positions C.1 and C.2. 6. The applicant has met the requirements of 10 CFR 50.63 by demonstrating that suitable environmental conditions to support operator access/egress and equipment functionality will be maintained during a station blackout event and its associated recovery period in those areas which contain equipment whose function is required for the safe shutdown of the plant in the event of a station blackout and by
