REVIEW RESPONSIBILITIES Primary - Auxiliary Plant Systems Branch (ASBSPLB)1 Secondary - None Emergency Preparedness and Radiation Protection Branch (PERB)2 I. AREAS OF REVIEW The function of the control room area ventilation system (CRAVS) is to provide a controlled environment for the comfort and safety of control room personnel and to assure support the 3 operability of control room components during normal operating operation, anticipated 4 operational transient occurrences, and design basis accident conditions. Portions of the CRAVS 5 may also be relied upon to support withstanding, or coping with, and recovering from a station blackout event.6 The ASBSPLB reviews the CRAVS from the air intake to the point of discharge where the 7 system connects to the gaseous cleanup and treatment system or station vents to assure ensure conformance with the requirements of General Design Criteria 2, 4, 5, 19, and 60 and 10 CFR 50.63. The review includes components such as air intakes, ducts, air conditioning units, filters, 8 blowers, isolation dampers or valves, and exhaust fans. The review of the CRAVS covers the 9 control room, switchgear and battery room, access control area, control building heating, ventilating, and air conditioning (HVAC) equipment room, and computer room. 1. The ASBSPLB reviews the CRAVS to determine the safety significance of the system. 10 Based on this determination, the safety-related portions of the system are reviewed with respect to the functional performance requirements to maintain the habitability of the control room area and other safety-related areas served by the control room ventilation DRAFT Rev. 3 - April 1996 9.4.1-2 system during adverse environmental occurrences, during normal operation, anticipated operational occurrences, and subsequent to postulated accidents. The review includes the effects of radiation, combustion and other toxic products, and the coincidental loss of offsite power. The review of this Standard Review Plan (SRP)
