Dear Mr. Keppler:
In accordance with Reference 1, this report is notification of the discovery of the condition of two systems which required corrective measures to prevent operation in a manner less con-servative than assumed in Technical Specifications.
The results of analyses of fuel oil samples taken as routine sur-veillance on December 15, 1978, were received on December 29, 1978, and reviewed on January 3, 1979.
The analyses, performed at an.
off-site independent testing laboratory revealed water and sedi-ment percentages of 0.1% in the fuel in tanks of the 1B Emergency Diesel Generator, the lA High Pressure Service Water Pump and the IB High Pressure Service Water Pump.
LACBWR Technical Specifi-cations (References 2 and 3) provide a limit of 0.05% for water and sediment in fuel used for this equipment.
The results of the analyses and the impact upon plant operations were reviewed by the Operations Review Committee on January 3, 1979.
Consultation with a specialist of a diesel engine manu-facturer was conducted to ascertain the effect of the reported concentrations of moisture and sediment.
Hic conclusion stated a negligible effect.

Mr. James G.
Keppler LAC-6064 Regional Director January 4, 1979 Detailed discussions of the problem related to the determination of operability of the diesel engines were conducted with Mr. Kenneth Ridgway of your staff and Messrs. Stan Nowicki and Tom Wambach of the NRC Licensing Branch.
With the definition of an immediate program of fuel oil re-sampling, partial purging and replenishment of the affected diesel fuel oil tanks together with operational surveillance of the affected diesel engines for the high presstne service water pumps and with reliance upon the electric-driven high pressure service water pump for back-up fire protection, concurrence was received from Mr. Tom Wambach that the fire suppression water system was operable.
Each of the affected fuel oil tanks were resampled at three elevations prior to partial purging.
Tank truck fuel oil was added to each tank.
This oil was also sampled.
Following replenishment, one sample of fuel oil was taken from each of the tanks.
Altogether, fourteen samples were obtained for prompt delivery to the off-site testing laboratory.
Results of tests are ex-pected Friday, January 5, 1979.
Prompt notification of test results and corrective actions was made to Mr. Kenneth Ridgway, USNRC-Region III, on January 3, 1979.
If there are any questions concerning this report, please contact us.
