Unit Name Point Beach Unit 1 Date _.

June 8, 1981 Completed By C. W.' Fay Telephone 414/277-2811-Unit 1 operated at 390 MWe net throughout the period with three load reductions. On May 11, 1981, at 1630 hours0.0189 days <br />0.453 hours <br />0.0027 weeks <br />6.20215e-4 months <br />, while performing a nuclear instrument check on power range Channel 41, .a control power fuse , associated with the

- turbine runback circuit, blew, causing a turbine runback f rom 390 MWe ne t to 29 7 MWe ne t. Following replacement of

~ the fuse and ,a faulty diode in the turbine runback circuit, Unit 1 was returned to 390. MWe net ten minutes later. On May 16, 1991, at 0300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br />, load reduction was commenced to accommodate Technical Specification valve testing. At the request of the Power System Supervisor, load reduction was discontinued at ' 382 MWe net and Unit 1 was restored to 390 MWe net. On May 17, 1981, at 0 300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br /> , load was reduced to 275 MWe net at the request of the Power System Supe rvisor. Unit 1 was restored to 390 MWe net at 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br />, on May 17, 1981.

Safety-related maintenance for the period included repairs to the control room emergency filtration system.

On May 15,1981, at.1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> , during Technical Specification testing, the control room emergency filtration system was found to be inoperable. The overall system flow rates were below the requirements of Technical Specification 15.3.12.2.C. The low system flow rate was due to an improperly balanced backdraft damper located downstream of the fan discharge of fan W14A, and an improperly adjusted balancing damper located just upstream of the system's roughing filter. The dampers were adjusted and the system was tested satis factorily. The control room emergency filtration system was returned to service at 0700 hours0.0081 days <br />0.194 hours <br />0.00116 weeks <br />2.6635e-4 months <br />, on May 20, 1981. This occurrence is reportable in accordance with Technical Specification 15.6.9.2.B.2 as a 30 day report.

(Licensee Event Report 81-005/03L-0)

On May 13, 1981, the 3D Diesel generator would not close in on the bus curing the performance of the revised Operations refueling test (ORT) # 3, Safeguards Actuation with Loss of AC.- The test called for manually opening the generator breaker following automatic bus energization on loss ' of AC and then manually closing the breaker to assure that the system will resequence the bus loads. It was

'k v

Q e

determined that the performance of this portion of the revised '

ORT required additional specific breaker operating procedures to allow manual closing of the breaker. On.May 20, 1981, at 0615

~ hours, the 3D Diesel generator was retested satisfactorily using the modified procedure. This event was not a reportable occurrence, but has been documented as a-significant operating event for train-ing purposes.

Failure of 2CV-2083, a containment isolation valve, to close when .

actuated is a technical violation of . containment integrity as de fined in Technical Specification 15.1.d. Failure of 2CV-2083 to close upon actuation was due to excessive stem to packing

-friction resulting from dried out packing. The packing was-adjusted, the stem was lubricated, and the valve was tested satisfactorily and returned to operation at 1330 hours0.0154 days <br />0.369 hours <br />0.0022 weeks <br />5.06065e-4 months <br />, on May 26, 1981. - This occurrence is reportable as a 14 day report in accordance with Technical Specification '15.6.9.2.
