that any failure will not adversely affect the safety-related functions of the facility. The review procedures below are for a typical safety-related CSF system. For cases that vary from this typical arrangement, the reviewer will adjust the review procedures discussed below. 1. The SAR is reviewed to confirm that the facility description and the 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. Allowable operational degradation of components (e.g., pump leakage) and the procedures that will be followed to detect and correct degraded conditions when they become excessive are described. Using failure modes and effects analyses or independent calculations, the reviewer confirms that the facility is capable of losing any active component and still meeting minimum flow requirements to the safety-related systems. C. The use of tank coatings, floating covers, and other passive components to protect the purity and cleanliness of the condensate is described. These components are evaluated to provide assurance that the methods used to prevent degradation and the procedures to detect such degradation would be effective in protecting the safety-related water supply from adverse effects. 2. The facility P&IDs, layout drawings, and component descriptions and characteristics are reviewed to confirm the following: A. Safety-related portions of the CSF are correctly identified and are isolable from the nonsafety-related 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 verify that they show the means for accomplishing isolation, and the facility description is reviewed to identify
