REVIEW RESPONSIBILITIES Primary - Power Systems Branch (PSB) Secondary- None I. AREAS OF REVIEW The emergency diesel engine combustion air intake and exhaust system (EDECAIES) supplies combustion air of reliable quality to the diesel engines*, and exhausts the products of combustion from the diesel engines to the atmosphere. The PSB reviews the system from the outside air intake to the combustion air supply lines connected to the diesel engine interface, and from the exhaust connections at the diesel engine interface to the discharge point outside the building to assure conformance with General Design Criteria 2, 4, 5, and 17. 1. The PSB reviews the EDECAIES to verify that: a. The system design meets appropriate seismic design classification requirements and the components are designed, fabricated, erected, and tested to acceptable quality standards. b. The essential portions of the system are housed in or on a seismic Category I structure that is capable of protecting the system from extreme natural phenomena and external missiles. c. Each diesel engine has an independent combustion air intake and exhaust system. d. The consequences of a single active failure in an engine combustion air intake or exhaust system will not lead to the loss of function of more than one diesel generator. 2. The PSB will determine the adequacy of the design, installation, inspection and testing of all electrical systems (sensing, control and power) required 'As defined by the engine manufacturer.
