REVIEW RESPONSIBILITIES Primary - Power Systems Branch (PSB) Secondary - None I. AREAS OF REVIEW The PSB review of the emergency diesel engine starting system (EDESS) includes those system features necessary to assure reliable starting of the emergency diesel engine following a loss of offsite power to assure conformance with the require- ments of General Design Criteria 2, 4, 5, and 17. The review includes the system air compressors, air dryers, air receivers, devices to crank the diesel engine, valves, piping up to the connection to the engine interface,' filters, and associated ancillary instrumentation and control systems. 1. The PSB reviews the EDESS to verify that: a. Each emergency diesel engine has reliable, redundant starting systems of adequate starting capacity. b. The system complies with appropriate seismic requirements and quality standards, and has been properly designed, fabricated, erected, and tested. c. Essential portions of the system are housed within seismic Category I structures capable of protecting the system from extreme natural phenom- ena, missiles, and the effects of pipe whip or jet impingement from high- and moderate-energy pipe breaks. 2. The PSB will determine the adequacy of design, installation, inspection and testing of all electrical components (sensing, control, and power) required for proper operation of the system, including interlocks.
