OPERATIO:iAL

SUMMARY

AUGUST, 1981 8/1/81 - 8/14/81 The unit remained shutdown following the reactor trip on July 30, 1981 to repair the boot seal between low pres-sure turbine #1 and high pressure condenser. The seal was replaced with a new wider one.

8/15/81 The reactor was critical at 1412 hours0.0163 days <br />0.392 hours <br />0.00233 weeks <br />5.37266e-4 months <br />.

8/16/81 - 8/31/81 The turbine generator was synchronized on line at 0335 hours0.00388 days <br />0.0931 hours <br />5.539021e-4 weeks <br />1.274675e-4 months <br />.

The reactor power was slowly increased and attained 100%

full power on August 19, 1981 with the generator gross load at approximately 911 + 10 MWe.

The reactor power was maintained at 100% full power for the remainder of the month.
