REVIEW RESPONSIBILITIES Primary - Auxiliary Systems Branch (ASB) Secondary - None I. AREAS OF REVIEW The compressed air system (CAS) provides air to safety-related equipment and also to plant equipment used only for normal facility operation. ASB reviews the entire compressed air system since there may be cases where two systems or subsystems are provided, i.e., a safety-related compressed air system (SRCAS), and a station service system for nonsafety-related equipment. If the two systems are intercon- nected, then the area of review will extend from the safety-related portion to the outermost isolation valve on all interconnections between the two systems. If the systems are not connected, then the review will be limited to the SRCAS. The ASB reviews the SRCAS to ensure conformance with the requirements of General Design Criteria 1, 2, and 5. 1. ASB reviews the systems to identify the safety-related air-operated devices that are supplied by the system and whether each requires a source of supply air in order to perform the safety-related function. 2. ASB then reviews the systems to determine that a failure of a component or the loss of a compressed air source does not negate functioning of a safety- related system. 3. The ASB reviews the system to determine that the effects of failure of non- seismic Category I equipment or components will not affect the functioning of the SRCAS. 4. ASB reviews the design of the SRCAS with respect to the following: a. Capability to isolate portions or components of the system in case of component malfunction. Rev. 1 - 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.
