Some of the major tasks completed were: low pressure turbine rotor upgrade, steam generator insp0ction and repairs, reactor coolant pump motor inspection, charging pump discharge check valves replacement, internallifting rig work,10 Bani: transformer modification of tap changer, and refueling.

The reactor was taken critical on the 13th at 0100 and the generator was placed on-line on the 14th at 1355. The generator was taken off line on the 15th at 0423 to conduct tests on the new LP rotors (reactor was at hot standby). After the rotor tests were completed the generator was placed on-line on the 16th at 0114. The Unit obtained full power operation on the 19th at 0526.

Because of the LP rotor upgraue the Unit is producing additional megawatts. The values for the Designed Electrical Rating and Maximum Dependable Capacity (both gross and net) will be changed aftor the Unit completes an URGE test.
