n a generic basis for aspects of heat removal systems common to a class of containments, or by adopting the results of previous reviews of plants with essentially the same system. 1. Upon request from CSBSCSB, the secondary review branchesreview branches with 47 48 review interface responsibilities, as noted in subsection I, will provide input for the 49 areas of review stated in subsection I of this SRP section. CSBSCSB obtains and uses 50 such input as required to assureensure that this review procedure is complete. 51 CSBSCSB assuresensures that the design and functional capability of the containment 52 53 heat removal system conform to the requirements of General Design Criteria 38, 39, and 40. 2. CSBSCSB determines the acceptability of a containment heat removal system design by 54 reviewing failure modes and effects analyses of the system to be sure thatensure that:55 a. All potential single failures have been identified and no single failure could incapacitate the entire system; b. verifying thatEngineered safety feature design standards have been applied; c. reviewingThe system design provisions for periodic inservice inspection and operability testing to ensure that the system and components are accessible for inspection and all active components can be tested; and d. reviewingThe capability exists to monitor system performance and control 56 active components from the control room so that the operator can exercise control over system functions or isolate a malfunctioning system component. 3. CSBThe SCSB reviews analyses of the net positive suction head available to the spray 57 system pumps. CSBThe SCSB assuresensures that the analyses for the recirculation 58 59 phase are done in accordance with the guidelines of Regulatory Guide 1.1, i.e., are based on maximum expected temperature of the pumped fluid and with atmospheric pressure in the containment. For clarification, the analyses should be based on the assumption that DRAFT Rev. 5 - April 1996 6.2.2-8
