rocedure is complete. In the review, the staff evaluates spent fuel pool cooling and cleanup system and its makeup system with respect to their capability to perform the necessary functions during all conditions, including normal operation, refueling, and accident conditions. 9.1.3-8 Revision 2 - March 2007 1. The reviewer will identify the safety function of the system for refueling and normal operations by reviewing the information provided in the application pertaining to the design bases and criteria and the safety evaluation section. The application section describing the system functional performance requirements is also reviewed to determine that it describes the minimum system heat transfer and system flow requirements for normal plant operation, component operational degradation requirements (i.e., pump leakage, etc.) and describes the procedures that will be followed to detect and correct these conditions should degradation become excessive. The reviewer, using failure modes and effects analyses, determines that the system is capable of sustaining the loss of any active component and evaluates, on the basis of previously approved systems or independent calculations, that the minimum system requirements (cooling load and flow) are met for these failure conditions. The reviewer will evaluate the system drawings and component descriptions for the following points: A. Essential portions of the system are correctly identified and are isolable from the nonessential portions of the system. The reviewer verifies that the drawings clearly indicate the physical division between each portion and indicate classification changes. The reviewer also ensures that system drawings show the means for accomplishing isolation and that the system description identifies minimum performance requirements for the isolation valves. For the typical system, the reviewer examines drawings and reviews descriptions to verify that adequate isolation valves separate nonessential portions
