and correct these conditions. The reviewer, using results from failure modes and effects analyses as appropriate, determines that the safety-related portion of the system is capable of functioning in spite of the loss of any active component. 2. The system PMIDs, layout drawings, and component descriptions and charac- teristics 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 the physical divisions between such portions and indicate 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 dam- pers. For the typical system, the drawings and description are reviewed to verify that two automatically operated isolation dampers in series separate nonessential portions and components from the essential portions. The review for seismic design is performed by SEB and the review for quality group and seismic classification is performed by MEB as indicated in subsection I of this SRP section. 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 includ- ed, and that the P&IDs indicate any points of change in design classification. 9.4.2-4 Rev. 2 - July 1981 c. Design provisions have been made that permit appropriate inservice inspection and functional testing of system components important to safety. It is acceptable if the SAR information delineates a test- ing and inspection program and if the system drawings show the necessary test recirculation loops around fans or isolation
