Abstract
This is a voluntary report.
On January 25, 2002, diesel fuel was delivered onsite for the emergency diesels. Technical Specification surveillance requirement 4.8.1.1.2.d.2 for fuel analysis is implemented by Surveillance Test Procedure, STP 606.001. This procedure directs that a sample be obtained from each truck delivering diesel fuel oil and selected analyses be performed prior to unloading into the storage tanks. As required, a sample was collected from the diesel fuel oil truck and the appropriate analyses were performed with acceptable results before the truck was unloaded. Seven additional analyses are required to be completed within 30 days of sampling the truck, however the sample collected from the diesel fuel oil truck was mistakenly discarded before the remaining seven analyses were completed.
The cause was determined to be human error. The supervisor had told the individual that it was okay to discard all lube oil samples located on the sample cart. The individual discarded all the old samples on the cart including the diesel fuel oil sample.
The immediate corrective action was to perform all analyses on the contents of both storage tanks. The tanks were determined to be within specification. The emergency diesel generators were operable at all times.

CONDITIONS PRIOR TO EVENT
Mode 1 - 100% Reactor Power
DESCRIPTION OF EVENT
On January 25, 2002, a diesel fuel oil truck delivered No. 2 diesel fuel oil for the emergency diesel generator storage tanks. Technical Specification 4.8.1.1.2.d.2 requires twelve diesel fuel oil analyses for each truck arriving onsite for unloading. A sample was collected from the truck for the twelve analyses. In accordance with Surveillance Test Procedure STP 606.001, the five required analyses were performed before the truck was unloaded to ensure the quality of the oil. The remaining seven analyses were required to be completed within thirty days of sampling the truck. The diesel fuel oil sample was placed on a sample cart, which contained additional oil samples from various plant equipment.
On February 4, 2002, it was determined that the diesel fuel oil sample collected on January 25, 2002 had been mistakenly discarded before the remaining seven analyses were completed.
(If more space is required, use additional copies of NRC Form 366A)
CAUSE OF EVENT
The cause was determined to be a miscommunication and a failure to check samples prior to disposal. The Chemistry Supervisor told the individual that it was okay to discard all old lube oil samples located on the sample cart. The individual discarded all old samples on the cart including the sample collected on January 25, 2002.
ANALYSIS OF EVENT
This issue did not impact the operability of the emergency diesel generators, since the diesel fuel oil in the diesel fuel oil storage tanks was determined to be satisfactory. Representative samples were obtained from the fuel oil tanks and analysis was performed for all twelve parameters, including those not analyzed on the discarded fuel truck sample. The analyses determined that the fuel oil in the tanks met acceptance criteria for an operable fuel oil source to supply the diesels.
The diesel fuel oil storage tanks have a capacity of 52,000 gallons each with the level maintained at a minimum of 50,680 gallons of fuel during Modes 1 through 4. Each tank received approximately 1200 to 1400 gallons of diesel fuel oil. Since the fuel oil met all required specifications and was determined to be satisfactory, the diesels were operable at all times. All Limiting Conditions for Operations were met and the plant did not operate in a condition prohibited by Technical Specifications.
INTERIM CORRECTIVE ACTIONS Samples from the "A" and "B" Diesel Fuel Oil Storage Tanks were collected and analyzed on February 5, 2002. All sample results were determined to be satisfactory. The analysis determined that the fuel oil in the tanks met the acceptance criteria for an operable fuel oil source to supply the diesels.
ADDITIONAL CORRECTIVE ACTIONS
This was the first occurrence of this event in the years that the Oil Laboratory has been in operation. The personnel involved have been counseled on the need for accurate communications and self-checking. The site has a comprehensive human performance initiative on going which addresses these tools on a site wide basis.
Additionally, the Oil Laboratory has evaluated the event and administrative actions have been taken to ensure that this does not occur in the future.
