Telephone 414/221-2001

. Unit 1 operated at approximately 494 MWe net throughout the D

' period with no significant load reductions.

Primary to secondary leakage was stable at a detectable rate.

'On December 10,-1989, the No. 2 turbine governor valve closed when a relay card in the governor electro-hydraulic system failed.

The valve closing. caused a' change in power which was sensed by the reactor.

This initiated a-false " control rod drop" signal

.and subsequently-turbine power self-adjusted to approximately 410 MWe, o

After seven-hours of investigation and corrective maintenance, the unit returned to full power operations.

Safety related maintenance conducted during the period included:

. packing adjustments to service water pump P-32C; calibration of auxiliary feedwater flow transmitters.FT-4007 and FT-4014; modifications to~DYOC and DYOD inverter transfer switches; repairs.to pressurizer spray valve controller HC-431H; repairs to auxiliary feedwater pump bearing cooling supply solenoid valve;

' repairs 1to a tube-leak on emergency diesel glycol cooler HX-55B; seal and outboard bearing replacement on component water cooling pump P-11B; and the restoration of a yellow bus power supply to residual heat removal controller instrument ~HC-626.

' Point Beach Unit'2 Date January 5, 1990 Completed By-C.'W. Krause Telephone:

414/221-2001 Unit 2 operated at approximately 501 MWe net throughout'the j

period with no-significant load reductions.

Primary to secondary leakage was less than one-gallon per day.

On December 5, 1989; the unit surpassed 63 billion KWh of

+

generation.

'i i On' December 11, 1989, two maintenance workers received first and second~ degree burns from hot 1 water and steam while conducting

~

n corrective maintenance on a: heater drain pump discharge check valve...The workers were transported to a local hospital for

, evaluation and treatment.

-Safety related maintenance conducted during the period included:

L calibration of four " Bank D" rod insertion limit modules; gasket i

replacement of component cooling water check valve 2-724B; tightening.the' flange of CVCS temperature control valve

_2-TCV-130; calibration of reactor coolant loop A flow

-transmitters FT-411 and FT-413; repairs to pressurizer pressure

bistable'PC-430E/F; limit switch adjustments to safety injection
