NRRRATIVE SGt9JE OF KNIHLY OPERATING EXPERIENCE UNIT 1 APRIL 1994 April 1

'Ihe Unit operated at a ncninal value of 100% output until 1

0740 hours0.00856 days 0.206 hours 0.00122 weeks 2.8157e-4 months when output was reduced to approximately 97% durity a routine maintenance surveillance s uchiare to amplete a Channel III d T/Tawr calibration.

'Ihe power reduction was perfomed as a precaution to avoid a turbine runback ard potential plant trip with one out of three turbine runback signals already tripped by the calibration s ucelare and a secmd channel known to experience ereamicnal noise spiking at.

higher power levels.

At 1900 hours0.022 days 0.528 hours 0.00314 weeks 7.2295e-4 months the Unit returned to a ncminal value of 100% output follcwing coupletion of the Channel III AT/Tavg calibration.

'Ihe Unit continued to cperate at a ncminal value of 100%-

output.

At 0830 hours0.00961 days 0.231 hours 0.00137 weeks 3.15815e-4 months the Unit rehM output to approximately 97% during a routine maintenance surveillance p ucslare to caplete a Channel II A T/Tavg calibration, h power reduction was performed as a precaution to avoid a turbine runback and potential plant trip with one out of three turbine runback signals already tripped by the calibraticn procedure ard a second channel known to experience occasional noise spiking at higher power levels.

At 1430- hours the Unit returned to a ncninal value of 100% output following cmpletion of the Channel II AT/Tavg calibration.

'Ihe Unit continued to operate at a ncninal value of 100%

output.

At 1330 bcurs the Unit ruhywi output to approximately 97% in an attenpt to eliminate nuisance alarms created by more frequent noise spiking frcn Channel I 6T instrumentation at higher power levels.

April 15 h Unit continued to operate at a nominal valua of 100%

outpat.

With one Cooling ibwer Pump being overhauled and only three Cooling Ibwer Pumps available ard operating, a load ruluction to approximately 95% was u.m ars si at 1240 hours0.0144 days 0.344 hours 0.00205 weeks 4.7182e-4 months due to high condenser hotwell tempuature and backpressure. Once conditions in the condenser hotwell had inproved, the Unit commenced a return to full power at 1800 hours0.0208 days 0.5 hours 0.00298 weeks 6.849e-4 months .

April 16 The Unit achieved approximately 100% output at 0030 hours3.472222e-4 days 0.00833 hours 4.960317e-5 weeks 1.1415e-5 months .

April 17 h Unit operated at a nominal value of 100% output.

through April 24 April 25 The Unit continued to operate at a nominal value of 100%

output.

With one Cooling Tower Pump still out of service, the Unit commenced a reduction in output at 1250 hours0.0145 days 0.347 hours 0.00207 weeks 4.75625e-4 months to approximately 96% to inprove conditions in the condenser hotwell.

Once corditions in the condenser hotwell had inproved, the Unit commenced a return to full power at 2100 houru.

N Unit achieved approximately 100% output at 2300 hours0.0266 days 0.639 hours 0.0038 weeks 8.7515e-4 months .

April 26 The Unit continued to operate at a nominal value of 100%

output.

With one Cooling Ibwer Pump still out of service, the Unit ccrime: red a reduction in outpIt at 1040 hours0.012 days 0.289 hours 0.00172 weeks 3.9572e-4 months to approximately 89% to improve conditions in the condenser hotwell.

Once corditions in the cx:nienser hotwell had improved, the Unit cuumenced a return to full power at 2049 hours0.0237 days 0.569 hours 0.00339 weeks 7.796445e-4 months .

The Unit achieved approximately 100% output at 2300 hours0.0266 days 0.639 hours 0.0038 weeks 8.7515e-4 months .

April 27 The Unit continued to cperate at a ncairal value of 100%

output.

With one Cooling Ibwer Pump still out of service, the Unit commenced a reduction in output at 0808 hours0.00935 days 0.224 hours 0.00134 weeks 3.07444e-4 months to approximately 96% to improve conditions in the condenser hotwell.

Following return of the "D" Cooling Tower Pump to service and subsequent improvement of condenser hotwell conditions, the Unit was returned to full power at 1700 hours0.0197 days 0.472 hours 0.00281 weeks 6.4685e-4 months .
