v. 3 - April 1996 For those areas of review identified above as being reviewed as part of the primary review responsibility of other branchespart of the review under other SRP sections, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP sections of the corresponding primary branch.43 II. 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. 44 The design of safety-related portions of the CRAVS is acceptable if the integrated design of the system is in accordance with the following criteria: 1. General Design Criterion 2 (GDC 2), "Design Bases for Protection Against Natural Phenomena," as related to the system being capable of withstanding the effects of 45 earthquakes. Acceptance is based on meeting the guidance of Regulatory Guide 1.29, position C.1 for safety-related portions and position C.2 for nonsafety-related portions. 2. General Design Criterion 4 (GDC 4), "Environmental and Dynamic Effects Design Bases," with respect 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 associated with normal operation, maintenance, testing, and postulated maintaining environmental conditions in the control room compatible with the design limits of essential equipment located therein during normal, transient, and accident conditions. The evaluation with respect to GDC 4 also includes evaluation of 46 the adequacy of environmental support provided to structures, systems, and components important to safety located within areas served by the CRAVS.47 3. General Design Criterion 5 (GDC 5), "Sharing of Structures, Systems, and Components," as related to shared systems and components important to safety. 48 4. General Design Criterion 19 (GDC 19),
