SUMMARY

The Unit began the report period operating at approximately 98% output due to the 1A/1C Moisture l Separator Reheaters (MSRs) being out-of-service. The MSRs could not be returned to service l because their supply valve was inoperable due to a stem / plug separation which could not be repaired until the Unit was shutdown. Repair of the valve was planned for during the Unit 1 Surveillance Outage which vtarted on 04/13/99.

On 04/11/99 at 1707 hours0.0198 days <br />0.474 hours <br />0.00282 weeks <br />6.495135e-4 months <br />, the Unit commenced a power reduction to approximately 50% output to perform planned testing of the Main Steam Safety Valves (MSSVs). An output of approximately 48%

was achieved at 2300 hours0.0266 days <br />0.639 hours <br />0.0038 weeks <br />8.7515e-4 months <br /> on 04/11/99. Following satisfactory completion of MSSV testing, the Unit began to increase power to approximately 62% output at 1156 hours0.0134 days <br />0.321 hours <br />0.00191 weeks <br />4.39858e-4 months <br /> on 04/12/99. An output of approximately 62% was achieved at 1600 hours0.0185 days <br />0.444 hours <br />0.00265 weeks <br />6.088e-4 months <br /> on 04/12/99. This was done at the request of Duquesne Light Company System Operations prior to commencing the final power reduction and removing the Unit from service for the planned Unit i Surveillance Outage.

The Unit was taken off-line at 0236 hours0.00273 days <br />0.0656 hours <br />3.902116e-4 weeks <br />8.9798e-5 months <br /> and Mode 2 was entered at 0312 hours0.00361 days <br />0.0867 hours <br />5.15873e-4 weeks <br />1.18716e-4 months <br /> on 04/13/99. As continuous rod insertion was ongoing to bnng the Unit into Mode 3, Control Banks "C" and "D" were l

inserted without incident, however, upon reaching 100 steps for Group 2 of Bank "B", an " urgent '

alarm" was received that inhibited further manual rod mobon The Unit was confirmed to have entered Mode 3 at 0347 hours0.00402 days <br />0.0964 hours <br />5.737434e-4 weeks <br />1.320335e-4 months <br /> on 04/13/99.

trip breakers were manually opened and all rods fully inserted. The cause for the " urgent alarm" was ,

due to a failed card in the Rod Control System. The Unit began to cool down and Mode 4 was  !

entered at 1550 hours0.0179 days <br />0.431 hours <br />0.00256 weeks <br />5.89775e-4 months <br /> on 04/13/99. Cold shutdown (Mode 5) was entered at 2235 hours0.0259 days <br />0.621 hours <br />0.0037 weeks <br />8.504175e-4 months <br /> on 04/13/99.

The Unit remained in Mode 5 to perform required shutdown surveillance testing in accordance with plant Technical Specifications.

l Upon completion of all required surveillance testing and repair of a Reactor Plant Component Cooling Water System leak in the 1B Reactor Coolant Pump lower motor beanng lube oil cooler, the Unit began to heat-up and entered Mode 4 at 1409 hours0.0163 days <br />0.391 hours <br />0.00233 weeks <br />5.361245e-4 months <br /> on 04/28/90.

The Unit was synchroruzad to the electncal grid at 0302 hours0.0035 days <br />0.0839 hours <br />4.993386e-4 weeks <br />1.14911e-4 months <br /> on 04/12/99 officially ending the seventh refueling outage.

The Unit was subsequently removed from service at 1309 hours0.0152 days <br />0.364 hours <br />0.00216 weeks <br />4.980745e-4 months <br /> on 04/12/99 to pomwt planned turbine overspeed trip testing. Followng a successful turbine overspeed trip test, e previous Main Exater ground test orcust brush contact fadure was repaired, and replacement of two cards in the EH Control Cabinet was performed to resolve an inability to raise Turbine speed above 1800 rpm for synchronization. The Unit was then re-synchronized to the electrical grid at 0413 hours0.00478 days <br />0.115 hours <br />6.828704e-4 weeks <br />1.571465e-4 months <br /> on 04/13/99 and output was escalated to approximately 29%. Following completion of a flux map at approximately 29% output, the Unit commenced to increase output to approximately 50% at 2037 hours0.0236 days <br />0.566 hours <br />0.00337 weeks <br />7.750785e-4 months <br /> on 04/14/99.

An output of approximately 47% was achieved at 0200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> on 04/15/99 to permit required surveillance testing of the Main Steam Safety Valves. Followng satisfactory completion of Main Steam Safety Valve testing, the Unit commenced to increase output to approximately 75% st 1315 hours0.0152 days <br />0.365 hours <br />0.00217 weeks <br />5.003575e-4 months <br /> on 04/15/99. An output of approximately 73% output was achieved at 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br /> on 04/15/99. Followmg completion of a flux map at approximately 73% output, the Unit commenced to increase output to approximately 90% at 1600 hours0.0185 days <br />0.444 hours <br />0.00265 weeks <br />6.088e-4 months <br /> on 04/17/99. An output of approximately 90%

was achieved at 2140 hours0.0248 days <br />0.594 hours <br />0.00354 weeks <br />8.1427e-4 months <br /> on 04/17/99. Following a heat balance and an adjustment to the nuclear instrumentation, an output of approximately 100% was achieved at 0254 hours0.00294 days <br />0.0706 hours <br />4.199735e-4 weeks <br />9.6647e-5 months <br /> on 04/19/99.

The Unit continued to operate at a nominal value of 100% output until 1313 hours0.0152 days <br />0.365 hours <br />0.00217 weeks <br />4.995965e-4 months <br /> on 04/23/99 when output was reduced to approximately 99% to support Main Unit Turbine (MUT) Govemor Valve testing. This was required following switching of Govemor Valve No.1 and No. 4 control sequencing to reduce flow induced vibrations on the No.1 and No. 3 MUT Throttle Valves. Following satisfactory MUT Govemor Valve testing, the Unit was retumed to a nominal value of 100% output at 1901 hours0.022 days <br />0.528 hours <br />0.00314 weeks <br />7.233305e-4 months <br /> on 04/23/99.

The Unit continued to operate at a nommal value of 100% outlyut until 1556 hours0.018 days <br />0.432 hours <br />0.00257 weeks <br />5.92058e-4 months <br /> on 04/26/99.

Output was reduced by approximately 2% to gain extra margin as a conservative measure in order to prevent a possible turbine runback during the re-scaling of Loop i Delta-T/Tavg. Following completion of the re-scaling, the Unit was retumed to a nominal value of 100% output at 0540 hours0.00625 days <br />0.15 hours <br />8.928571e-4 weeks <br />2.0547e-4 months <br /> on 04/27/99.

The Unit condnued to operate at a nominal value of 100% output for the remainder of the report period.
