o 3/4.8. ELECTRICAL POWER SYSTEMS BASES (Contia*=d) tuel oil degradation during long term storage shows up as an increase in particulate, mostly due to oxidation.

The presence of particulate does not mean that the fuel oil will not burn properly in a diesel engine.

However, j

the particulatt can cause fouling of filters and fuel oil injection equip' ment,

{

wh1ch can cause engine failure.

{

Particulate cencentration should be determined in accordance with ASTM D2276-94, Method A.

This method involves a gravimotric determination of total particulate concentration in the fuel oil and has a limit of 10 mg/1. The 0.8 micron filters specified in ASTM D2276-94 may be replaced with membrane filters up to 3.0 microns.

This is acceptable since the closest tolerance fuel filter in the HC EDGs is a five micron particle retention duplex filter on the engine driven fuel oil pump.

It is acceptable to obtain a field sample for subsequent laboratory testing in lieu of field testing.

The total volume of stored fuel oil contained in two er more interconnected tanks must be considered and tested separately.

The trequency of this test takes into consideration fuel oil degradation trends that indicate the particulate concentration is unlikely to change significantly between frequency intervals.

The surveillance requirements for demonstrating the OPERABILITY of the diesel generators are in accordance with the recommendations for Regulatory Guide 1.9, " Selection of Diesel Generator Set Capacity for Standby Power l

Supplies", March 10, 1971, Regulatory Guide 1.108, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants", Revision 1 August 1977 and Regulatory Guide 1.137 " Fuel-Oil System;*
