NUREG-0800 IFormerly NUREG-75/087) LI REG(, .. U.S. NUCLEAR REGULATORY COMMISSION STANDARD REVIEW PLAN OFFICE OF NUCLEAR REACTOR REGULATION SECTION 9.5.7 EMERGENCY DIESEL ENGINE LUBRICATION SYSTEM REVIEW RESPONSIBILITIES Primary - Power Systems Branch (PSB) Secondary - None I. AREAS OF REVIEW The emergency diesel engine lubrication system (EDELS) provides essential lubrication to the components of the emergency diesel engines. The PSB reviews the EDELS and associated auxiliary systems to assure conformance with the requirements of GDC 2, 4, 5, and 17. The review includes system piping, pumps, components, and associated auxiliary equipment essential for system operation up to the engine interface.' 1. The PSB reviews the characteristics of the EDELS and system components with respect to the effect on functional performance of adverse environmental occurrences, abnormal operational requirements, and accident conditions. 2. The PSB determines that a malfunction or failure of a component, or the loss of a cooling source does not reduce the safety-related functional performance capabilities of the emergency powered systems. Further, the PSB review assures that: a. System components and piping have sufficient physical separation or barriers to protect the system from internally and externally generated missiles. b. The system is protected from the effects of pipe cracks or breaks in high- and moderate-energy piping. c. System components are designed in accordance with the design codes required by the assigned quality group and seismic category classifications. lAs defined by the engine manufacturer.
