ch input as required to assure that this review procedure is complete. 46 The condensate storage facility (CSF) may be designed either as a safety- related facility or as a nonsafety-related facility, depending on the plant. The safety function performed by the facility is to ensure an adequate supply of water to the auxiliary feedwater system in the event that it is 47 required for the safe shutdown of the reactor. Normal plant system functions performed by the DRAFT Rev. 3 - April 1996 9.2.6-8 CSF, such as makeup to the condenser hotwells and other auxiliary systems of the plant are reviewed to verify that failure will not have an adverse effect on the safety-related functions of the facility. The review procedures given below are for a typical CSF system of the safety- related type. For cases where there are variations from this typical arrangement, the reviewer will adjust the review procedures given below. However, the system design will be required to meet the acceptance criteria given in subsection II. 1. The Safety Analysis Report is reviewed to determine that the facility description, and piping and instrumentation diagrams (P&IDs) delineate the CSF equipment that is used for normal operation, abnormal operation, and accident conditions as 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
