REVIEW RESPONSIBILITIES Primary - Power Systems Branch (PSB)Plant Systems Branch (SPLB)1 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 PSBSPLB reviews the EDELS and 2 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) 1. The PSBSPLB reviews the characteristics of the EDELS and system components with 3 respect to the effect on functional performance of adverse environmental occurrences, abnormal operational requirements, and accident conditions. 2. The PSBSPLB determines that a malfunction or failure of a component, or the loss of a 4 cooling source does not reduce the safety-related functional performance capabilities of the emergency powered systems . Further, the PSBSPLB review assures that: 5 6 a. System components and piping have sufficient physical-separation or barriers to protect the system from internally and externally generated missiles. DRAFT Rev. 3 - April 1996 9.5.7-2 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. d. The system is housed in structures designed to seismic Category I requirements. e. Failure of nonseismic Category I structures or components will not affect the safety-related functions of the system. 3. The PSBSPLB will also review the design of the EDELS with respect to the following: 7 a. Functional capability during abnormally high site water levels (probable maximum flood). b. Capability for detection and control of system leakage. c. Measures to assure the quality of the lubricating oil. d. Capability for
