s follows: a. The facility functional requirements and the minimum flow requirements for supplying water to the auxiliary feedwater system and other safety-related .systems are described. b. Component allowable operational degradation (e.g., pump leakage) and the procedures that will be followed to detect and correct degraded conditions when they become excessive are described. The reviewer, using failure modes and effects analyses, or independent calculations, determines that the facility is capable of sustaining the loss 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: 9.2.6-4 Rev: 2 - July 1981 a. Essential portions of the CSF are correctly identified and are isolable from the nonessential portions of the system. The 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. Essential portions of the CSF, including the isolation valves sepa- rating seismic Category I portions from the nonseismic portions, are classified Quality Group C and seismic Category 1. 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 a loss of offsite
