SUMMARY

OF OPERATING EXPERIENCE UNIT 1 The unit entered the reporting period at a power level of 1068 11We (100t reactor power).

The unit remained on-line until May 23 at 1328 hours0.0154 days <br />0.369 hours <br />0.0022 weeks <br />5.05304e-4 months <br /> when a safety Injection occurred during surveillance testing due to a spurious signal.

At 0945 hours0.0109 days <br />0.263 hours <br />0.00156 weeks <br />3.595725e-4 months <br />, on flay 24 the reactor was made critical.,At 1510 hours0.0175 days <br />0.419 hours <br />0.0025 weeks <br />5.74555e-4 months <br />, the unit was synchronized to the grid.

The unit remained on-line for the remainder of the month.

The unit ended the reporting period on-line at a power level of 1070 MWe (100% reactor power).

UNIT 2 The unit entered the month at a power level of 906 MWe (84% reactor power).

On May 8 at 0814 hours0.00942 days <br />0.226 hours <br />0.00135 weeks <br />3.09727e-4 months <br />, a reactor trip occurred from low level in 2A steam generator in coincidence with feed flow / steam flow mismatch due to a loss of the 2B main feedwater pump.

At 1445 hours0.0167 days <br />0.401 hours <br />0.00239 weeks <br />5.498225e-4 months <br />, the reactor was made critical and'was synchronized to the grid at 1705 hours0.0197 days <br />0.474 hours <br />0.00282 weeks <br />6.487525e-4 months <br />.

The unit remained on-line for the remainder of the month and ended the reporting period at a power level of 965 MWe (89% reactor power).
