4. GDC 17 as to the capability of the fuel oil system to meet independence and redundancy criteria and the guidance and positions of the following: A. RG 1.137 as to the diesel engine fuel oil system design, fuel oil quality, and tests which are specified in regulatory positions C1 and C2. The regulatory position C1 addresses the design criteria for the fuel oil system such as materials, physical arrangement, and applicable codes and regulations. The physical arrangements 9.5.4-6 Revision 3 - March 2007 of the fuel oil system should provide for inservice inspection and testing in accordance with ASME Boiler and Pressure Vessel Code Section XI ,“Rules for Inservice Inspections.” Criteria for oil quality are addressed in the position C2. The fuel oil stored in the fuel supply tank or used for filling or refilling the supply tank should meet the Federal Fuel Oil, ASTM, or diesel-generator manufacturer requirements. The quality of fuel oil is determined by performing suitable tests and when it does not meet the prescribed standards it is replaced. Also, prior to adding new fuel oil to the supply tank the test for specific gravity, water sediment and viscosity testing should be performed and the fuel oil not meeting the test requirements should not be added to the tank. B. NUREG/CR-0660, "Enhancement of Onsite Emergency Diesel Generator Reliability" C. Each diesel engine with its own EDEFSS. D. ANSI/ANS-59.51 regarding the onsite fuel oil storage for each diesel generator being sufficient to operate the diesel generator following any design basis event and a continuous loss of off-site power either for seven days, or for the time required to replenish the fuel from sources outside the plant site following any design event without interruption of the operation of the diesel generator, whichever is longer. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the
