s of any active component and of meeting minimum flow requirements to the safety-related systems. 2. The facility P&IDs, layout drawings, and component descriptions and characteristics are reviewed to determine the following: a. EssentialSafety-related portions of the CSF are correctly identified and are 48 isolable from the nonessentialnon safety-related portions of the system. The 49 P&IDs are reviewed to verify that they clearly indicate the physical division between each portion. System drawings are also reviewed to see that they show the means for accomplishing isolation, and the facility description is reviewed to identify minimum performance requirements for the isolation valves. b. EssentialSafety-related portions of the CSF, including the isolation valves 50 separating seismic Category I portions from the nonseismic portions, are classified Quality Group C and seismic Category I. c. Design provisions have been incorporated that permit appropriate inservice inspection and functional testing of system components important to safety. It will be acceptable if the SAR delineates a testing and inspection program and if the system drawings show the necessary test recirculation loops around pumps or isolation valves that would be required by this program. 3. The reviewer verifies that the system has been designed so that facility functions are maintained, as required, in the event of adverse natural phenomena such as tornadoes, hurricanes, and floods, and/or in the event of a loss of offsite power or station blackout. 51 9.2.6-9 DRAFT Rev. 3 - April 1996 The reviewer evaluates the facility, using engineering judgment and the results of failure modes and effects analyses, to determine the following: a. The failure of portions of the facility or of other systems not designed to seismic Category I standards and located close to essentialsafety-related portions of the 52 facility, or nonseismic Category I structures that house, support, or are close to
