Trojan Operating Report May 1989 OPERATIONS The plant began the month in Mode 6, with the reactor defueled and

. preparations for refueling in progress. Preparations were in progress for the lifting of the reactor vessel head and the commencement of refueling operations.

Fuel reload commenced on May 11. The reload was completed on May 16.

Eddy Current testing on the four steam generators was begun May 22 and continued through the end of the month.

Reactor Coolant Pump flange bolt work was commenced on April 29 and in

. progress at the end of May.

Earlier inspection of the main generator rotor bars disclosed an' unacceptable amount of copper dust and flakes. The generator has been cleaned and is being reassembled with new slot insulation and separators between bars to correct the copper dusting problem. Inspection of the high pressure turbine identified the need for extensive repairs of the diaphragms due to erosion at the blade roots. The repairs to the diaphragms are complete. Turbine

.rer.ssembly continued through the end of the month.

On April 25, in-service inspection of the reactor vessel was begun. It was.

completed on May 8. An indication was discovered in the "A" loop nozzle to

-vossel weld. Examination has determined that is within code allowable limits.

Westinghouse 1.as completed an analysis providing additional assurance that the flaw is acceptable.

l l Testing of Electrical Penetration connections comieenced on May 3. .A number of I

electrical cable wires had pulled loose from a containment electrical penetration assembly during seal replacement. Several more connections pulled-loose during testing and the scope of the work was increased to test more connections. The testing continued through the end of the month.

Flux thimble testing was conducted from May 21 to May 25. Several tMmbles have unacceptable amounts of thinning in their walls. The requiref mrrective actions are under evaluation.

The plant ended the month in Mode 5, with the reactor refueled.

MAINTENANCE

, Significant maintenance completed during this period includes:

1 Replacement of degraded cables inside containment.

Repair of the 30 inch main feed water header.

Repair of the main condenser water box joints.
