lines. The system description in the SAR is reviewed to verify that there are no high- or moderate-energy piping systems close to the lube oil system or that protection from effects of failure will be provided. The means of providing such protection are given in Chapter 3 of the SAR and procedures to review the information presented are given in the corresponding SRP sections. 4. The descriptive information, P&IDs, related system drawings, and system analyses in the SAR are reviewed to assure that essential portions of the system will function following design basis accidents, assuming a concurrent single active component failure. The reviewer evaluates the results of failure modes and effects analyses presented in the SAR to assure functioning of required components, traces the availability of these components on system drawings, and checks that minimum system requirements are met for. each degraded situation over required time spans. For each case, the design is acceptable if minimum system requirements are met. 9.5.7-6 Rev. 2 - July 1981 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his review supports conclusions of the following type, to be included in the staff's safety evaluation report: The emergency diesel engine lubrication system (EDELS) includes the pumps, heat exchangers, valves, piping, makeup piping, and the points of connection or interfaces with other systems. The scope of review of the emergency diesel engine lubrication system for the plant included layout drawings, flow diagrams, piping and instrumen- tation diagrams, and descriptive information for the system and supporting systems that are.essential to its operation. The essen- tial portions of the EDELS that are necessary for the safe shutdown of the reactor or necessary to mitigate the consequences of an acci- dent are designed to seismic Category I and Quality Group C. The staff concludes that the design of the emergency diesel engine
