I. Narrative Summarv of Ooeratina Experiences Unit 2 began the month of December at 75.2% of Rated Thermal Power (RTP) in end-of-cycle coastdown. Power reduction occurred .throughout this operating period due to end-of-cycle coastdown.

On December 4, 1994, at 2211 hours0.0256 days <br />0.614 hours <br />0.00366 weeks <br />8.412855e-4 months <br />, power was reduced to 64%

RTP to perform hydraulic control unit (HCU) maintenance. On ,

December 7, 1994, HCU maintenance was completed and power ,

was restored to 72.3% RTP by 2300 hours0.0266 days <br />0.639 hours <br />0.0038 weeks <br />8.7515e-4 months <br />. ,

On December 29, 1994, at 1549 hours0.0179 days <br />0.43 hours <br />0.00256 weeks <br />5.893945e-4 months <br />, ,aower was reduced from  !

64.2% RTP slightly to place the B Reactor Feedpump in ,

service and remove the C Reactor Feedpump from service.

Power was restored to 64.2% RTP at 2110 hours0.0244 days <br />0.586 hours <br />0.00349 weeks <br />8.02855e-4 months <br />. >

Unit 2 ended this operating period at 63.7% of RTP in end-of-cycle coastdown. -
