and effects analyses are considered to ensure that the system meets these requirements. These will be acceptable verifica- tion of system functional reliability. 4. The descriptive information, P&IDs, SRCAS drawings, and failure modes and effects analyses in the SAR are reviewed to ensure that the SRCAS portion of the compressed air system will function following design basis acci- dents assuming a concurrent single active 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 . 9.3.1-5 Rev. 1 - July 1981 system drawings, and checks that the SAR contains verification that mini- mum compressed air flow requirements are met for each degraded situation for the required time spans. For each case the design will be acceptable if minimum system requirements are met. 5. The reviewer verifies that an adequate maintenance and periodic testing program is planned to ensure continuous reliable functioning of SRCAS. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and that his review supports conclusions of the following type, to be included in the staff's safety evaluation report: The compressed air system includes all components and piping and the points of connection or interfaces with other systems. The safety-related cum- pressed air system requires a continuous air supply to safety-related com- ponents and is classified seismic Category I and Quality Group C. The basis for acceptance in the staff review has been conformance of the applicant's design and design criteria for the safety-related compressed air system to the Commission's regulation as set forth in the general design criteria, and to applicable regulatory guides, staff technical positions, and industry standards. The staff concludes that the design of the compressed air system is acceptable and conforms to the requirements of General Design Criteria
