ines that the safety-related portion of the system is capable of functioning in spite of the loss of any active component. The system review also should demonstrate compliance with applicable industry standards: American National Standards Institute/American Nuclear Society (ANSI/ANS) 59.2-1985, “Safety Criteria for Nuclear Power Plant HVAC Systems Located Outside Primary Containment,” and American National Standards Institute/American Society of Mechanical Engineers (ANSI/ASME) AG-1-1985, “Code on Nuclear Air and Gas Treatment.” 2. The system P&IDs, layout drawings, and component descriptions and characteristics are then reviewed to determine that: A. Essential portions of the SFPAVS are correctly identified and are isolable from nonessential portions of the system. The P&IDs are reviewed to verify that they clearly indicate physical divisions between such portions and design classification changes. System drawings are also reviewed to verify that they show the means for accomplishing isolation, and the system description is reviewed to identify minimum performance requirements for the isolation dampers. 9.4.2-7 Revision 3 - March 2007 For the typical system, the drawings and description are reviewed to verify that two automatically-operated isolation dampers in series separate nonessential from essential portions and components. B. Essential portions of the SFPAVS, including the isolation dampers separating essential from nonessential portions, are classified seismic Category I. Component and system descriptions in the SAR that identify mechanical and performance characteristics are reviewed to verify that the above classifications have been included, and that the P&IDs indicate any points of change in design classification. C. Design provisions have been made that permit appropriate inservice inspection and functional testing of system components important to safety. Compliance with the industry standard American Society for testing and Materials (ASTM)
