CH PIPEXX Reactor power reduced to 55% to re-move the West main feed pump from service to repair weld leak on a 1" drain line connection on the pump discharge piping. Reactor power was maintained at 55% over weekend due to low system demand and was returned to 100% on 830606.

A slow power reduction to 90% was started on 830624 to extend core life.

90% reactor power was reached on 830627.

The valve packing was adjusted and the leak-off line was replaced.

C&I-l While testing the power / load unbalance system in the turbine gen-

)

erator electrohydraulic control cabinet, a turbine runback occurred.

l A Rosemount pressure transducer for cold reheat pressure had failed high. The transmitter was repaired and reinstalled.

C&I-2 Pressurizer level indicator, NPL-153, on pressurizer level protection set III deviated 7% from other level indication channels. The chan-nel was declared inoperable and its associated bistables were placed in the " trip" mode. Level transmitter NPL-153, reference leg, was pumped full of water to restore that channel to operability. Channel deviation was then less than 1.5% of level span.
