DOCKET NO. 50-282 UNIT PRAIRIE ISLAND NO.1 DATE MARCH 2, 1995 COMPLETED BY DALE DUGSTAD TELEPHONE 612-388-1121-4376 MONTH:

FEBRUARY 1995 The Unit was base loaded this month.

On the 18th at 0013 a power reduction was started to conduct a turbine valve test and to clean condenser water box tubes.

At 0847 the generator was taken off line (reactor remained critical) starting a planned outage to replace a turine trip solenoid valve that had the potential of initiating an unplanned turbine trip. The information about this valve was recently obtained by NSP from a I

Westinghouse Turbine User's group meeting.

After all the work was completed the unit went on line at 1646 and reached full power operation at 2353.

i l

The outage ended a continuous operating run of 190 days CURRENT CONTINUOUS OPERATING RUN OF 10 DAYS.
