ACCEPTANCE CRITERIA Acceptability of the CRAVS design, as described in the applicant’s safety analysis report (SAR) is based on relevant regulations, specific general design criteria, and regulatory guides. 9.4.1-4 Revision 3 - March 2007 The design of safety-related portions of the CRAVS is acceptable if the integrated design of the system is in accordance with the requirements and SRP acceptance criteria presented in this section. Requirements Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. GDC 2, “Design Bases for Protection Against Natural Phenomena,” as it relates to system capability to withstand the effects of earthquakes. 2. GDC 4, “Environmental and Dynamic Effects Design Bases,” as it relates to the CRAVS being appropriately protected against dynamic effects and being designed to accommodate the effects of, and to be compatible with, the environmental conditions of normal operation, maintenance, testing, and postulated accidents. The GDC 4 evaluation includes the adequacy of environmental support for safety-related SSCs within areas served by the CRAVS. 3. GDC 5, “Sharing of Structures, Systems, and Components,” as it relates to shared SSCs among nuclear power units. 4. GDC 19, “Control Room,” as it relates to providing adequate protection to permit access to and occupancy of the control room under accident conditions. 5. GDC 60, “Control of Release of Radioactive Materials to the Environment,” as it relates to system capability to suitably control release of gaseous radioactive effluents to the environment. 6. 10 CFR 50.63, as it relates to necessary support systems providing sufficient capacity and capability to ensure the capability for cope with a station blackout event. An analysis to determine capability for withstanding (if an acceptable alternate ac source is provided) or coping with a station blackout event is required. The analysis should address, as appropriate,
