C.

Peterson TELEPHONE 414/755-2321, Ext. 361 Unit 2 operated at approximately 466.1 MWe net throughout this report period with one significant' load reduction and one reactor trip.

The load reduction was a result of condenser tube inspection and repair; the recutor trip was caused by a supply lead to a DC breaker pulling loose, which deenergized DC distribution panel D-22 and resulted in a reactor trip.

During this period, Unit 2 experienced one reportable event in accordance with 10 CFR 50.73, LER 91-006, Unit 2 Reactor Trip, due to modification work.

Safety-related maintenance included the following:

replaced and calibrated signal process assembly in gamma metrics startup rate meter; inspected and retightened coupling on steam sensing line to auxiliary feedwater turbine driven pump; replaced turbine independent overspeed protection Channel A speed control card;.

and replaced nut and retorqued safety injection piping support.
