e (OL) applications, the procedures are utilized to verify that the initial design criteria and bases are implemented appropriately in the final design as set forth in the final safety analysis report (FSAR). The review procedures for OL applications include a determination that the content and intent of the applicant’s technical specifications are in agreement with the requirements for system testing, minimum performance, and surveillance developed as a result of the staff review, as indicated in subsection I of this SRP section. 1. The SAR is reviewed for whether the EDECAIES is a dedicated system and whether the description and related diagrams clearly delineate system components and modes of system operation. The interfacing branches review the seismic design bases and the quality and seismic classifications as indicated in subsection I of this SRP section. The interfacing branches assure that essential EDECAIES portions are classified Quality Group C and seismic Category I. Components and system descriptions in the SAR that identify mechanical and performance characteristics are reviewed to verify whether the seismic and quality classifications have been included and whether the piping and instrumentation diagrams (P&IDs) indicate any points of change at system or system component interfaces. 2. The SAR is reviewed to ascertain that sufficient space has been provide around the components to permit inspection of the system components. 3. The SAR is reviewed to assure that the combustion air intake and exhaust are arranged and located to prevent dilution or contamination of the intake air by exhaust products, fire extinguishing (gaseous) media, or other gases intentionally or accidentally released on site from precluding operation of the diesel engines at rated power output or causing engine shutdown as a consequence of any meteorological or accident condition. 4. The SAR is reviewed to verify that if the intake air flow or engine exhaust depends upon the
