Unit 1 January 1 through January 31, 1995 I.

Narrative Summarv of Operatino Experiences Unit 1 began the month of January at a nominal 100% of rated thermal power (RTP).

6 On January 2, 1995, at 0004 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, power reduction began in preparation to rework the 1B reactor recirculation punp seal.

Power was reduced to 21.2% RTP.

During the powar reduction the seal stabilized and cavity pressure returncd to normal.

The situation was reviewed and it was determined that the recirculation pump seal would not be reworked at this time.

Power was returned to 100% RTP on January 3, t

Power was restored to 100% RTP at 2115 hours0.0245 days <br />0.588 hours <br />0.0035 weeks <br />8.047575e-4 months <br />.

On January 23, 1995, at 1254 hours0.0145 days <br />0.348 hours <br />0.00207 weeks <br />4.77147e-4 months <br />, power was reduced to 80%

RTP for troubleshooting of a control valve pressure switch.

Power was restored to 100% RTP at 1950 hours0.0226 days <br />0.542 hours <br />0.00322 weeks <br />7.41975e-4 months <br />.

On January 30, 1995, at 0748 hours0.00866 days <br />0.208 hours <br />0.00124 weeks <br />2.84614e-4 months <br />, the 1A Recirculation Pump motor generator set tripped when a contract worker bumped into the MG set cabinet.

Power was stabilized at 35%

RTP.

The recirculation MG set was restarted at 1116 hours0.0129 days <br />0.31 hours <br />0.00185 weeks <br />4.24638e-4 months <br /> and power ascension began at 1242 hours0.0144 days <br />0.345 hours <br />0.00205 weeks <br />4.72581e-4 months <br />.

Power was restored to 100% RTP at 1037 hours0.012 days <br />0.288 hours <br />0.00171 weeks <br />3.945785e-4 months <br /> on January 31, 1995.

Narrative Summary of Operatina Experiences Unit 2 began the month of January at 63.7% of Rated Thermal Power (RTP) in end-of-cycle coastdown.

Power reduction occurred throughout this operating period due to end-of-cycle coastdown.

On January 15, 1995, at 0001 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, power was reduced to 30%

RTP for scaffold erection in preparation for refueling activities.

Scaffold erection was completed and power ascension began at 1535 hours0.0178 days <br />0.426 hours <br />0.00254 weeks <br />5.840675e-4 months <br />.

At 1650 hours0.0191 days <br />0.458 hours <br />0.00273 weeks <br />6.27825e-4 months <br />, at 37% RTP, the Unit entered single loop operation when the 2B Reactor Recirculation Motor-Generator (MG) set was removed from service in order to work on the 2B MG set ground detection system.

On January 17, 1995, at 0003 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />, power was increased to 43.4% RTP.

On January 18, 1995, at 2220 hours0.0257 days <br />0.617 hours <br />0.00367 weeks <br />8.4471e-4 months <br />, power was reduced to 35%

RTP due to a 2A reactor recirculation pump runback.

The runback occured while securing the 2A condensate pump from service and a low level signal was recieved.

Level returned to normal and power was stabilized at 35% RTP.

Power was restored to 42% RTP at 0902 hours0.0104 days <br />0.251 hours <br />0.00149 weeks <br />3.43211e-4 months <br /> on January 19, 1995.

RTP in order to place the 2B Reactor Recirculation MG set in service.

The 2B MG set was returned to service on January 26, 1995.

At 1830 hours0.0212 days <br />0.508 hours <br />0.00303 weeks <br />6.96315e-4 months <br /> power was returned to 55.8% RTP.

At 1000 hours0.0116 days <br />0.278 hours <br />0.00165 weeks <br />3.805e-4 months <br /> the Unit was manually shutdown from 21% RTP and the plant entered Operational Condition 3, Hot Shutdown.

On January 27, 1995, at 1857 hours0.0215 days <br />0.516 hours <br />0.00307 weeks <br />7.065885e-4 months <br /> Operational Condition 4, Cold Shutdown, was entered when the reactor coolant temperature reached 200 degrees F.

On January 28, 1995, at 1315 hours0.0152 days <br />0.365 hours <br />0.00217 weeks <br />5.003575e-4 months <br />, Operational Condition 5 was entered due to detensioning of the reactor pressure vessel head.
