Also, repair of the generator hydrogen seals was necessary due to excessive hydro-gen leakage (approximately 15.000 cu ft/ day). The hydraulic anubbers were inspected per PT 19.6.0.1.

The generator hydrogen seals were removed and remachi..ed or replaced as required. Overtime was worked to complete this outage.

1 N/A CC VALV0P Thd unit was separated from the grid to repair a steam leak in a main steam line drain valve in the Reactor Building. Apparently, a valve travel limit switch fails to operate at the proper setpoint causing the operator mounting bolts to break when the motor continued to run.

This caused a bent valve stem and a steam leak past the valve stem packing. The stem was straightened enough to repack the valve.

The operator will be installed at a later date after a new stem is insta11eu. All main steam drain valves were checked for proper operation on both units. Overtime was worked.

1 N/A WA Pipexx The unit separated from the grid due to a nuclear service water leak..

The leak was caused by defective cement lining on the inside of a pipe re-ducing elbow exposing the carbon steel pipe to salt water corrosion. The defective cement lining was caused by erosion. The area surrounding hole was ultrasonically tested to assure that the problem was localized. The elbow was repaired in accordance with Approved Plant Modification 79-200.

The defective elbow will be replaced during the next refueling outage. A study is in progresa to determine long-term suitability of all cement-lined piping. Overtime was worked.
