e Attachment to ET 96-0040 Page 1 of 1 INSERT "B" DIESEL FUEL OIL TESTING PROGRAM in accordance with Tecnnical Specification 6.8.4, a Diesel Fuel Oil Testing Program to implement required testing of both new fuel oil and stored fuel oil shall be established. For the intent of this specification, new fuel oil shall represent diesel fuel oil that has not been added to the Diesel Fuel Oil Storage Tanks. Once the fuel oil is added to the Diesel Fuel Oil Storage Tanks, the diesel fuel oil is considered stored fuel oil, and shall meet the Technical Specification requirements for stored fuel oil.
Tests hsted below are a means of determining whether new fuel oil is of the appropriate grade and has not been contaminated with substances that would have an immediate detrimental impact on diesel engine combustion. If results from these tests are within acceptable limits, the new fuel oil may be added to the storage tanks without concern for contaminating the entire volume of fuel oilin the storage tanks. These tests are to be conducted prior to adding the new fuel to the storage anks, but in no case is the time between receipt of the new fuel oil and conducting the tests to exceed 3D tys. The tests, limits, and applicable ASTM standards being used to evaluate the condation of new fuel oil are-1.
By sampling new fuel oilin accordance with ASTM D4057 prior to addition to storage tanks and:
2.
By venfying in accordance with the tests specified in ASTM D975-81 prior to addition to the storage tanks that the sample has:
a)
An API Gravity of within 0.3 degrees at 60 *F or a specific gravity of within 0.0016 at 60/60 *F.
when compared to the supplier's certificate or an absolute specific gravity at 60/60 'F or greater than or equal to 0.83 but less than or equal to 0.89 or an API gravity of greater than or equal to 27 degrees but less than or equal to 39 degrees; b)
A kinematic viscosity at 40 *C of greater than or equal to 1.9 centistokes, but less than or equal to 4.1 centistokes, if gravity was not determined by companson with the supplier's certification; c)
A flash point equal to or greater than 125 *F; and d)
A water and sediment content of less than or equal to 0.05% when tested in accordance with ASTM D1796-83.
Fa: lure to meet any of the above limits is cause for rejecting the new fuel oil, but does not represent a failure to meet the Limiting Condition for Operation of Technical Specification 3.8.1.1, since the new fuel oil has not been added to the diesel fuel oil storage tanks.
Within 30 days following the initial new fuel oil sample, the fuel oil is analyzed to establish that the other properties specified in Table 1 of ASTM D975-81 are met, when tested in accordance with ASTM D975-81, except that the analysis for sulfur may be performed in accordance with ASTM D1552-79, ASTM D2622-82, or ASTM D4294-90 An exception to ASTM D129, which is specified in ASTM D975-81, has been taken. ASTM D129 uses a Banum precipitation method for the determination of sulfate after oxidation has occurred. The use of any wet lab sulfate analysis is acceptable since the determination ic made in the aqueous rinse water for the oxidation process, in the event the correct fuel oil properties are not met, Action g provides an additional 30 days from the time that it is determined that the correct fuel oil properties are not met to meet the Diesel Fuel Oil Testing Program limits. The additional 30 day penod is acceptable because the fuel oil properties of interest, even if they are not within limits, would not have an immediate effect on emergency diesel generator operation. The diesel fuel oil surveillance in accordance with the Diesel Fuel Oil Testing Program will ensure the availabihty of high quality diesel fuel oil for the emergency diesel generators.
At least once every 31 days, a sample of fuel oilis obtained from the storage tanks in accordance with ASTM D2276-
- 83. The particulate contamination is venfied to be less than 10 mg/ liter when checke@dansewdh basedD ASTM D2276-83. Method A. The filter size for the determination of particulate contamination will De J.u micron instead of 0 8 micron as specified by ASTM D2276-83. The filtered amount of diesel fuel oil will be approximately one liter when possible. Also, it is acceptable to obtain a field sample for subsequent laboratory testing in lieu of field testing.
Fuel oil degradation during long term storage shows up as an increase in particulate, due mostly to oxidation. The presence of particulate does not mean the fuel oil will not bum properly in a diesel engine. The particulate can cause fouling of filters and fuel oil injection equipment which can cause engine failure.
The frequency for performing surveillance on stored fuel oil is based on stored fuel oil degradation trends which indicate that particulate concentration is unlikely to change significantly between surveillances.
