onsafety-related source to a seismic Category I source. i. If a changeover from a nonsafety-related condensate storage source to a safety-related water source is required for safe shutdown or accident mitigation, then the changeover feature (automatic) should meet all the requirements for a safety-related system or component. 4. The descriptive information, P&IDs, system drawings, and failure modes and effects analyses in the SAR are reviewed to assure that essential portions of the CSF will function as needed following design basis acci- dents, assuming a concurrent single active component failure. The reviewer evaluates the information presented in the SAR to determine the ability of required components to function, traces the availability of these components on system drawings, and checks that the SAR contains verifica- tion that system flow requirements are met for each accident situation for the required time spans. For each case, the design will be acceptable if minimum system flow requirements are met. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his review supports conclusions of the following type, to be included in the staff's safety evaluation report: The condensate storage facility (CSF) includes all components and piping associated with the facility to the points of connection or interfaces with other systems. The review has determined the adequacy 9.2.6-6 Rev. 2 - July 1981 of the applicant's proposed design criteria and bases for the condensate storage facility and the requirements for sufficient water supply to safety-related systems during normal, abnormal, and accident conditions. Portions of the CSF that are necessary for safe shutdown or necessary to mitigate the consequences of an accident are classified seismic Category I and Quality Group C. The staff concludes that the design of the condensate storage facility is acceptable and meets the requirements of General Design Criteria 2, 5, 44, 45,
