SUMMARY

OF OPERATING EXPERIENCE UNIT 1 The unit entered the reporting period at a power level of 1050 MWo (100% reactor power).

The unit trioped on August 17 at 2157 hours0.025 days <br />0.599 hours <br />0.00357 weeks <br />8.207385e-4 months <br /> during a lightning storm.

The unit was nade critical on August 18 at 2027 hours0.0235 days <br />0.563 hours <br />0.00335 weeks <br />7.712735e-4 months <br /> and was synchronized to the grid at 2216 hours0.0256 days <br />0.616 hours <br />0.00366 weeks <br />8.43188e-4 months <br />.

On August 26 at 0117, the unit was shut down to re-pair minor secondary stcam leaks in the containment.

The unit was made critical on August 27 at 0204 hours0.00236 days <br />0.0567 hours <br />3.373016e-4 weeks <br />7.7622e-5 months <br /> and was synchronized to the grid at 0523 hours0.00605 days <br />0.145 hours <br />8.647487e-4 weeks <br />1.990015e-4 months <br />.

On August 31 at 1117 hours0.0129 days <br />0.31 hours <br />0.00185 weeks <br />4.250185e-4 months <br />, the unit tripped due to a power supply failure in the nod Control System.

The cause for this failure is still under investigation.

The unit ended the month in Hot Shutdown, e

UNIT 2 The unit entered thh reporting period at a power level of 960 MWe (89% reactor power).

The unit tripped on August 17 at 2157 hours0.025 days <br />0.599 hours <br />0.00357 weeks <br />8.207385e-4 months <br /> during a lightning storn.

The unit was nade critical on August 18 at 1130 hours0.0131 days <br />0.314 hours <br />0.00187 weeks <br />4.29965e-4 months <br /> and was synchronized to the crid at 1442 hours0.0167 days <br />0.401 hours <br />0.00238 weeks <br />5.48681e-4 months <br />.

At 1446 hours0.0167 days <br />0.402 hours <br />0.00239 weeks <br />5.50203e-4 months <br />, the unit tripoed due to a feedwater flow control and steam ceneraror level problen during a routine reactor start up.

Feedwater flow control problems are typical of reactor startups.

The unit was nade critical at 1617 hours0.0187 days <br />0.449 hours <br />0.00267 weeks <br />6.152685e-4 months <br /> and was synchronized to the grid at 1820 hours0.0211 days <br />0.506 hours <br />0.00301 weeks <br />6.9251e-4 months <br />.

The unit was on-line for the remainder of the month and the ended the reporting period at a power level of 930 MWe (37% reactor power),
