Peterson TELEPHONE 414/755-2321 Unit 1 operated at approximately 486 MWo not through the first five days of this month.
Unit 1 was taken off-line at 0;38 on April 6 and the reactor made subcritical at 0327 on the same day.
This was in preparation for U1R18, refueling outage.
During steam generator eddy current inspections, one tube in "A" steam generator was discovered with isolated tube degradation of approximately 60% (this is in excess of the Technical Speci-fication plugging criteria).
This tube was plugged.
One tube in the "B" steam generator was plugged as a preventive measure (damage less than 40% degradation) due to tube support vibration.
This event is detailed in Licensee Event Report 90-002.
On April 25, retention pond radiation monitoring channel RE-230 had been out of service greater than 30 days.
The NRC resident inspector was given notification per Technical Specifications.
Safety-related maintenance included:
repacking of containment isolation valves 1-953 and 1-955; internal cleaning of pressurizer power operated relief valve 1-430; minor leak repairs to safety injection valves 1-689B and 1-889A; recalibration of steam flow transmitter FT-475; repairs to steam generator level bistable LC461 A/B; steam flow square root converter FM-464B, steam flow pressure compensator FM-465A; the replacement of the gain potentiometer for power range channel 42 and 44; the chemical cleaning of the Unit 1 containment service water piping; and the replacement of containment isolation valve SA-17.
