REVIEW RESPONSIBILITIES Primary - Auxiliary Systems Branch (ASB) Secondary - None I. AREAS OF REVIEW The ASB reviews the auxiliary and radwaste area ventilation system (ARAVS) from air intake to the point of discharge where the system connects to the gaseous cleanup and treatment system or station vents to assure conformance with the requirements of General Design Criteria 2, 5, and 60. The review includes components such as | air intakes, ducts, air conditioning units, blowers, isolation dampers, and roof exhaust fans. The review of the ARAVS covers the radwaste areas and controlled access nonradioactive areas and their relationship to safety-related areas in the auxiliary building. 1. The ASB reviews the functional performance requirements and the air treatment equipment for the ARAVS to determine whether the ventilation system or portions of the system have been designed or need to be designed as a safety-related system. Based on this determination, the safety-related part of the system is reviewed with respect to functional performance requirements during normal operation, during adverse environmental occurrences, and during and subsequent to postulated accidents, including the loss of offsite power. The ASB reviews safety-related portions of the system to assure that: a. A single active failure cannot result in loss of the system functional performance capability. b. Failures of nonseismic Category I.equipment or components will not result in unfiltered releases of radioactive contaminants. 2. The ASB also reviews safety-related portions of the ARAVS with respect to the following: Rev. 2 - July 1981 USNRC STANDARD REVIEW PLAN Standard review plans are prepared for the guidance of the Office of Nuclear Reactor Regulation staff responsible for the review of applications to construct and operate nuclear power plants.
