th in the final safety analysis report. The review procedures for OL applications include a determination that the content and intent of the tech- nical specifications prepared by the applicant are in agreement with the requirements for system testing, minimum performance, and surveillance devel- oped as a result of the LGB review as indicated in subsection I of this SRP section. The reviewer will select and emphasize material from the paragraphs below, as may be appropriate for a particular case. The primary reviewer will coordinate this review with the other branches' areas of review as stated in subsection I of this SRP section. The primary reviewer obtains and uses such input as required to assure that this review procedure is complete. 1. The SEB reviews the seismic design bases and the MEB reviews the quality and seismic classification as indicated in subsection I of this SRP sec- tion. The PSB assures that essential portions of the EDESS including the isolation valves separating essential and nonessential portions are classi- fied Quality Group C and seismic Category I. Components and system descriptions in the SARthat identify mechanical and performance character- istics are reviewed to verify that the above seismic and quality classifications have been included and that the P&IDs indicate any points of change at the systems and/or systems component interfaces. 2. The reviewer establishes that the EDESS description and piping and instru- mentation drawings (P&IDs) clearly delineate all modes of operation and include the means for monitoring, indicating, and controlling receiver air pressure as required by the engine starting service. The P&IDs are reviewed to determine that the receiver(s) has been provided with a pres- sure gauge, relief valve, drain valve, and automatic means of maintaining the receiver pressure within an allowable range, and suitable low pressure alarms. If there are piping interconnections between the dedicated air start systems, they
