number of architect-engineering companies having design responsibility in this area. Differences may occur in the number of redundant systems, in piping interconnections between diesel engines, and in sharing requirements between units. The reviewer will select and emphasize material from the paragraphs below to fit the particular design under review. The primary reviewer will coordinate this review with other branches for their particular areas of responsibility as stated in subsection I. The primary reviewer obtains and uses such input as required to assure that this review procedure is complete. 1. The SAR is reviewed to verify that the diesel engine fuel oil storage and transfer system description and related diagrams clearly indicate all modes of system operation, including the means for indicating, controlling, and monitoring fuel oil level, temperature, and pressure as required for uninterrupted operation. 2. The reviewer verifies that the system is designed to withstand the effects of seismic events, other design bases, natural phenomena, and internally and externally generated missiles. The review of internally generated missiles will consider the relative locations and orientation of components as placed in the facility. 3. Piping and interconnections between systems are reviewed to verify that single active failures will not cause unacceptable results. The associated drawings are examined to ascertain that sufficient space has been provided around the components to permit inspection, cleaning, maintenance, and repair. 4. The SEB ECGB reviews the seismic design bases and the MEBEMEB reviews the 44 45 quality and seismic classification as indicated in subsection I of this SRP section. The PSBSPLB assures that essential portions of the EDEFSS including the isolation valves 46 separating essential and nonessential portions are classified Quality Group C and Seismic Category I. Components and system descriptions in the SAR that identify mechanical and
