. I I I Abstract On November 22, 1987 at 0258 Operations personnel identified that the level in diesel oil storage tank T-10 [DC;TK] was below the Plant Technical Specification (TS) limit. TS 3.7.1 requires that a minimum of 16,000 gallons of oil be in T-10 when the primary coolant system [AB] is heated above 325 degrees. At the time of discovery, approximately 12,000 gallons of oil were in T-10. The reactor was critical with the Plant operating at 99 percent of rated power when the condition was discovered.
The event was discovered when a Control Room Operator noted a discontinuity *from previous data trends in the diesel oil storage tank level indication. Tank level was physically verified to be at approximately 12,000 gallons. An Unusual Event was declared and reactor power reduction initiated in accordance with TS 3.0.3. By 0732, approximately 4,900 gallons of oil had been added and storage tank level verified to be greater than 16,000 gallons.
The erroneous level indications have been attributed to temperature induced transmitter [DC;LT] drift. An evaluation has been undertaken to assess the potential for alternative level instrumentation. Until potential actions as a result of this evaluation are implemented, daily level verification will be performed inanually. ~"1,'"L Vr NllC"- . . L.ER_lj/-U4U-L!Ul

TS 3.7.1 requires that a minimum of 16,000 gallons of oil be in T-10 when the primary coolant system [AB] is heated above 325 degrees. At the time of discovery: approximately 12,000 gallons of oil were in T-10. The reactor was critical- with the Plant operating at 99 percent of rated power when the condition was discovered.
While performing TS Surveillance Procedure D/W0-1, "Operators Daily/Weekly/Bi-Weekly Items", a Control Room Operator noted a discontinuity (88 percent to 68 percent) from previous data trends in the diesel oil storage tank level indication. Tank level is monitored and Operators are alerted to low oil levels by level alarm LIA-1400
[DC;LA]. Consequently, an Auxiliary Operator (AO) was dispatched to physically measure tank level with a dipstick. Measurements revealed that approximately 12,000 gallons of oil were present in the tank.
At 0258 an Unusual Event was declared due to activation of TS 3.0.3. At 0310 Plant shutdown was commenced. Actions were immediately initiated to procure and assure oil delivery. By 0732 approximately 4,900 gallons of oil were delivered to T-10. The storage tank level was manually verified to assure greater than 16,000 gallons of oil were present and at 0736, the Plant secured from the Un~sual Event. At 0905 Operations personnel began raising th~ Plant power level from the lo~ of 80 percent achieved during the event.
Cause Of The Event The failure to assure compliance with TS 3.7.1 was caused by erroneous readings provided to Control Room Operators via level indicator LIA-1400. Investigations by Instrumentation and Control (I&C) personnel have attributed the erroneous readings to temperature induced transmitter drift within LT-1400 [DC;LT].
A review of post calibration records indicated that when the ambient temperature drops, the output of the transmitter increases and when the ambient temperature goes up, transmitter output decreases. An increase
- in transmitter output yields a positive (additive) indication of diesel oil storage tank level.
Corrective Actions After physically verifying the oil level in the storage tank, an Unusual Event was declared and reactor power reduction initiated.

TS Surveillance Procedure D/W0-1 has been changed to require physical verification (dipsticking) of T-10.
An evaluation has been under.taken to assess alternative level instrumentation. Until potential actions as a result of this evaluation have been taken, Operations personnel will use physical detection to verify tank level.
Analysis Of The Event The TS requirement to maintain 16,000 gallons of diesel oil ln storage tank T-10, in addition to the*TS requirement to maintain 2,700 gallons of diesel oil in each of the day tanks, T~25A and T-258 [DC;TK] will provide a diesel generator [EK;DG] operation under required loading conditions for a minimum of seven days.
As stated ln the basis for TS 3.7, this amount of diesel oil. is felt adequate since it lS considered incredible not to be able to secure oil from one of several sources within a radius of 70 miles in less than three days under the worst of weather conditions.
Th~ last ~eceipt and input of diesel oil to storage tank T-10 occurred on November 10, 1987. This input resulted ln the tank being filled to approximately 80 percent or 23,454 gallons.
At the time of the event, with approximately 12,000 gallons of diesel oil ln storage tank T-10, approximately five days of diesel operation was available. Therefore, no threat to the safety of the general public was presented.
This event is being reported in accordance with 10CFRS0.73(a)(2)(i) as an operational condition prohibited by TS.
Additional Information No known similar reportable events have been identified.
Diesel oil storage tank level transmitter LT-1400 is a Model 6178, manufactured by Robertshaw Controls (R290).
