SUMMARY

The Unit began the report period operating at approximately 95% output. This was being done in order to maintain reduced loading on the outboard motor bearings of the "A" Main Feedwater Pump until a planned power reduction to replace the motor bearings could be started on 4/2/02. Outboard motor bearing temperatures had been running higher in the previous month. At 0052 hours6.018519e-4 days <br />0.0144 hours <br />8.597884e-5 weeks <br />1.9786e-5 months <br /> on 4/2/02, the Unit began a power reduction to approximately 63% output in order to replace the motor bearings on the "A" Main Feedwater Pump. An output of approximately 63% was achieved at 0353 hours0.00409 days <br />0.0981 hours <br />5.83664e-4 weeks <br />1.343165e-4 months <br /> on 4/2/02. Cleaning of the "C" and "D" Main Unit Condenser Waterboxes was also performed during this planned reduction. Upon completion of repairs, the Unit commenced a return to full power at 0446 hours0.00516 days <br />0.124 hours <br />7.374339e-4 weeks <br />1.69703e-4 months <br /> on 4/5/02. A nominal value of 100% output was achieved at 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> on 4/5/02.

The Unit continued to operate at a nominal value of 100% output until 2110 hours0.0244 days <br />0.586 hours <br />0.00349 weeks <br />8.02855e-4 months <br /> on 4/12/02 when a planned power reduction to approximately 90% output was begun in order to clean the "A" and "B" Main Unit Condenser Waterboxes. An output of approximately 90% was achieved at 2215 hours0.0256 days <br />0.615 hours <br />0.00366 weeks <br />8.428075e-4 months <br /> on 4/12/02.

However, with the "A" Condenser Waterbox isolated and degrading Condenser vacuum conditions indicated, the Unit performed several unplanned incremental load reductions between 0750 and 1247 hours0.0144 days <br />0.346 hours <br />0.00206 weeks <br />4.744835e-4 months <br /> on 4/13/02 as a conservative action based on available Condenser vacuum indications, until the "A" Condenser Waterbox was returned to service. With the Unit operating at approximately 80% output, a return to approximately 90% output was commenced at 1532 hours0.0177 days <br />0.426 hours <br />0.00253 weeks <br />5.82926e-4 months <br /> on 4/13/02.

An output of approximately 90% was achieved at 1656 hours0.0192 days <br />0.46 hours <br />0.00274 weeks <br />6.30108e-4 months <br /> on 4/13/02.

The "B" Condenser Waterbox was removed from service and cleaned without any degrading Condenser vacuum conditions occurring. At 1331 hours0.0154 days <br />0.37 hours <br />0.0022 weeks <br />5.064455e-4 months <br /> on 4/14/02, the Unit commenced a return to full power.

A nominal value of 100% output was achieved at 1500 hours0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.7075e-4 months <br /> on 4/14/02. The Unit continued to operate at a nominal value of 100% output for the remainder of the report period.

I The Unit was shut down to Mode 2 (Reactor remained critical) due to degraded chemistry conditions in the Steam Generators caused by a tube leak in the *C" Waterbox of the Main Unit Condenser. The tube leak was repaired, and once chemistry conditions in the Steam Generators improved, the Unit was returned to full power.
