REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of diesel generator support systems Secondary - None I. AREAS OF REVIEW The emergency diesel engine lubrication system (EDELS) provides essential lubrication to emergency diesel engine components. Review of the EDELS and its auxiliary systems assures compliance with the requirements of General Design Criteria (GDCs) 2, 4, 5, and 17. The review includes system piping, pumps, components, and auxiliary equipment essential for system operation up to the engine interface.1 The specific areas of review are as follow: 1. The EDELS is reviewed to verify whether: A. Each emergency diesel engine has an independent and reliable lubrication system. B. The system is designed, fabricated, erected, and tested to acceptable quality standards. C. The system has boundary divisions between safety-related and nonsafety-related sections. 9.5.7-2 Revision 3 - March 2007 D. Sections of the system important to safety are housed within seismic Category I structures. E. Failure of any nonseismic Category I system, structure, or component (SSC) will not affect any EDELS safety-related function. F. The consequences of a single failure in an EDELS or the loss of a cooling source will not lead to a loss of more than one diesel generator. G. The design includes the capability for detection and control of system leakage, including the capability for isolating system portions in the event of excessive leakage or component malfunction. H. The design includes measures to assure lubricating oil quality. I. Instrumentation and control features permit operational testing of the system and assure that normal protective interlocks do not preclude engine operation during emergency conditions. J. The design includes measures for cooling the system and removing system heat load. K. Sufficient space permits inspection, cleaning, maintenance, and repair of the system. 2. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For
