been appropriately implemented in the final design as set forth in the final safety analysis report. The procedures for OL and DC reviews include a determination 66 that the content and intent of the technical specifications prepared by the applicant are in agreement with the requirements for system testing, minimum performance, and surveillance developed as a result of the staff's review. Upon request from the primary reviewer, the coordinating review branches will provide input for the areas of review stated in subsection I of this SRP section. The primary reviewer obtains and uses such input as required to ensure that this review procedure is complete. As a result of various CAS designs provided for different plants, there will be variations in system requirements. For the purpose of this SRP section, a typical system is assumed that has two independent systems, the plant service air system and a safety-related compressed air system (SRCAS)CAS is assumed to have two independent systems, a SSAS and an ICAS. For cases 67 where there are variations from this arrangement, the reviewer adjusts the review procedures given below. However, the system design would be required to meet the recommendations and requirements in subsection II of this SRP section. The reviewer will select and emphasize material from this SRP section as appropriate for a particular case. 1. The SAR is reviewed to identify from information in the system description section and the piping and instrumentation diagrams (P&IDs) the SRCAS equipment used for normal operation and for safety feature operation. The reviewer determines that the systems 68 affected by the loss of offsite power and subsequent loss of air supply will fail in a safe position.69 The SAR is reviewed to determine from information in the system description section whether the SSAS is used as a backup instrumentation and control air source and connected to the ICAS. If the two systems are interconnected, then the area of review
