LIC-04-0073 Page 1 ATTACHMENT I Response to Request For Additional Information Regarding License Amendment Request, "Addition Of Diesel Generator Fuel Oil, Diesel Generator Lubricating Oil, and Diesel Generator Starting Air Requirements" Question 1

[Omaha Public Power District] OPPD has stated it intends to increase the surveillance interval for sampling [Diesel Generator] DG fuel oil water content from 31 days to 92 days. Please provide plant-specific operating experience as well as design characteristics of the fuel oil system that demonstrate that the proposed surveillance interval change will not result in a significant impact in DG operability. Please include a description of the specific fuel oil storage design at [Fort Calhoun Station Unit No. 1] FCS, including any interconnected tanks that will need to be tested separately.

OPPD Response:

FCS water/sediment data for fuel oil storage tanks FO-1 and FO-1 0 for the last two years is provided in Attachment 2. Similar water/sediment percentages exist for prior years.

The static head of the fuel oil stored in the fuel oil storage tanks is sufficient to significantly minimize, if not eliminate, water intrusion into the system from underground sources. Condensation within the tanks is the most likely source of moisture development, but its significance is offset by the short time periods between sampling intervals of 92 days.

Also, tank wall thickness measurements for the fuel oil storage tanks have determined that there is no indication of external corrosion for either vessel.

The following is a description of the DG Fuel Oil System provided in the FCS Updated Safety Analysis Report (USAR) Section 8.4.1.2:

"Fuel for both diesels is supplied from a common 18,000 gallon underground storage tank by a separate supply line to each diesel. Additional diesel fuel oil is available in the auxiliary boiler underground storage tank should extended operation of the diesels be required.

A minimum of 10,000 gallons of diesel fuel oil is available from the auxiliary boiler underground storage tank for transfer to the diesel generator storage tank to permit operation of a diesel generator for 7 days in the event of an emergency.'

LIC-04-0073 Page 2 Each diesel has two fuel oil transfer pumps mounted on the engine. The pumps transfer fuel oil from the underground storage tank to a 300 gallon wall mounted day tank in the diesel room. Fuel oil is gravity fed from the day tank to a 550 gallon engine base tank. The 550 gallon base tank provides for more than 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> of operation of the engine before fuel transfer is necessary.

Power is supplied to the two fuel oil transfer pumps via a 480 volt, 3 phase transfer switch, fed by the station 480 volt auxiliary power system. In the event that both the normal and emergency power supplies are not available to the transfer switch when the engine is running, a manually interlocked breaker will supply power to the pumps from a transformer connected to the diesel generator output. The loss of power to the transfer pumps is annunciated in the control room.

Each transfer pump has a separate MAN-OFF-AUTO control switch and a common pump selector switch which selects one pump as the lead pump with the other pump as backup.

The level in the wall mounted Auxiliary Fuel Tank is maintained by automatic operation of the fuel oil transfer pump in response to low and high level signals. Low or high level in the auxiliary day tank is alarmed in the control room. Low level in the engine base tank is alarmed in the control room."

Question 2 Please describe the surveillance procedure for sampling and removing water from the DG fuel oil day tanks, base tanks, and underground storage tanks. Please include a description of the procedure and frequency by which DG-required underground fuel oil tanks are flushed through filtering agents and sampled for overall purity.

OPPD Response: to this letter contains the FCS sampling procedure CH-SMP-MI-0002, Diesel Fuel Sampling, which describes how multi-level and bottom samples of the main fuel oil storage tank FO-1, the auxiliary boiler fuel oil storage tank FO-10, the fuel oil day tanks FO-2-1/2 and the fuel oil base tanks FO-2C/D are performed.

The procedure for flushing the fuel oil storage tanks consists of the fuel oil being pumped from the bottom of the tank through a portable pump and filter cart housing a 10 gallon-per-minute (gpm) pump and a 10 micron filter with differential pressure gauges across the filter. The pump discharge is piped back into the tank at the top of the tank to promote good circulation. The filtering operation continues until there is no further increase in the filter differential pressure. This operation is prescribed by procedure PE-PM-FO-1000, Portable Filtering of Fuel Oil Storage Tanks (Attachment 4) and is performed annually on the fuel oil storage tanks.

LIC-04-0073 Page 3 Question 3 OPPD has proposed a time period of 30 days to be allowed to restore fuel oil properties if they are found to be out of the required limits. The licensee states, "Even if a DG start and load was required during this time interval and the fuel oil properties were outside limits, there is a high likelihood that the DG would still be capable of performing its intended function." This statement calls into question the validity and/or need for the limitations imposed on the fuel oil. Please provide a technical basis for the statement that the DG would be able to perform its intended function despite the fuel oil being outside of its required limits.

OPPPD Response:

The purpose of the fuel oil Technical Specification is to verify that the fuel oil is a high quality fuel oil. It does not define the lower boundary of fuel acceptability. As stated in the DG manufacturer (General Motors - Electro-Motive Division (EMD)) maintenance instruction on fuel oil, MI 1750, the fuel oil standards contribute to the "inherently low level of maintenance required by our engines." They also state in the section titled "Notes on Test Limits," that the sulfur specification ensures "1maximum engine life". They also state that the testing for chlorides is no longer necessary since modem refining techniques have virtually eliminated chloride contamination. Another statement made by EMD is that flash points that do not meet the EMD specification maybe used as long as fuel handling and storage precautions are maintained. The limits on fuel oil properties exist to preserve long term DG performance and reliability. Exceeding these limits for a relatively brief period will not have an immediate effect on DG operation.

2.1 Establish an area that is free of dirt and debris for staging of sampling equipment on top of diesel fuel truck.

2.2 Gently lower sample bomb into tank until the actuation mechanism strikes bottom and the actuation valve is lifted. Air will be vented from the bomb as it fills.

2.3 When full retrieve the bacon bomb.

2.4 While holding the bomb above the fuel level, pull the release lever to drain the contents of the bacon bomb back into the tanker. This flushes the bacon bomb.

2.5 Gently lower sample bomb into tank until the actuation mechanism strikes bottom and the actuation valve is lifted. Air will be vented from the bomb as it fills.

2.6 When full retrieve the bacon bomb. Allow time for it to drip before moving the bomb over the sample bottle.

2.7 Pull the release lever to drain the contents of the bacon bomb into the sample container. Fill the bottle to approximately 80% or less full to allow room for thermal expansion and sample mixing. Cap and ensure the sample is labeled.

2.8 Close the compartment hatch after the completion of sampling.

2.9 Repeat Steps 2.1 through 2.8 for each compartment to be sampled. Normally one liter of sample volume is required for each compartment.
