been considered.77 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.78 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his that the review 79 supports conclusions of the following type, to be included in the staff's safety evaluation report (SER):80 The control room area ventilation system (CRAVS) includes all components and ducting from the intake vents to the exhaust structure. All portions of the system whose failure may result in release of radioactivity which causes an offsite dose of more than 5 mSv (0.5 rem) to the whole body or its equivalent to any part of the body are 81 classified seismic Category I and safety related. Based on the review of the applicant's proposed design criteria, the design bases, and safety classification for the control room 9.4.1-13 DRAFT Rev. 3 - April 1996 area ventilation system, and the requirements for system performance to maintain a suitable environment during normal, abnormal, and accident conditions, the staff concludes that the design of the control room area ventilation system and auxiliary supporting systems is in conformance with the Commission's regulations as set forth in General Design Criteria Criterion 2, "Design Bases for Protection Against Natural Phenomena"; General Design Criterion 4, "Environmental and Dynamic Effects Design 82 Basis"; General Design Criterion 5, "Sharing of Structures, Systems, and 83
