REVIEW RESPONSIBILITIES Primary - Auxiliary Systems Branch (ASB)Plant Systems Branch (SPLB)1 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. SPLB reviews the compressed air system (CAS) which provides compressed air to station service equipment and to safety-related and non-safety-related equipment. There may be cases where two systems or subsystems are provided, i.e., an instrumentation and control air system (ICAS) which provides control air to safety-related and non-safety-related components and systems, and a station service air system (SSAS) which provides compressed air for the operation of non-safety-related service equipment (e.g., pneumatic tools, cleaning, etc.). If the two systems are interconnected, then the area of review 2 will extend from the safety-related portion ICAS to the outermost isolation valve on all 3 interconnections between the two systems and will include evaluation of the quality of the compressed air supplied from the SSAS . If the systems are not connected, then the review will 4 be limited to the SRCAS ICAS . The ASBSPLB reviews the portions of the SRCAS described 5 6 above to ensure conformance with the requirements of General Design Criteria 1, 2, and 5. The 7 SPLB also coordinates with other reviewers and reviews the CAS to ensure conformance with the requirements of 10 CFR 50.63 . 8 DRAFT Rev. 2 - April 1996 9.3.1-2 1. SPLB reviews the ICAS to ensure that the safety-related portions of the system are correctly identified and are isolable from the non-safety-related portions of the system.9 32. ASBSPLB reviews the system to determine that the effects of failure of nonseismic
