PO. Box 60 Fort Wayne. IN 46801 219 425 2111 lNblANA NlCHIGiAN POWER Mr. Galen Kilmer District Environmental Response Supervisor Michigan Department of Natural Resources P. O. Box 355 Plainwell, Michigan 49080 March 6, 1989

Dear Mr. Kilmer:

On February 24, 1989 at 1:30 p.m., personnel at the Indiana Michigan Power Company (1&M) Cook Nuclear Plant discovered a small leak in one of Unit 2's main turbine lubricating oil coolers. Lake water from the nonessential water system is pumped through cooler tubes to cool the lube oil. This small hole created a connection between the cooler and the nonessential water,. system which discharges to Lake Michigan.

I The leaking cooler was isolated and the tube was plugged.

To prevent any more possible future leaks in the cooler, eddy current testing was performed to determine the integrity of the remaining cooler tubes.

The exact amount of oil lost is not known, but 1156 gallons of lube oil were added to the tank to bring the level back up to the normal level. No oil was observed at the plant water discharges, nor along the shore or on the ice surrounding the discharges. Due to 'the very dangerous nature of lake ice no attempt was made to walk out on the ice for a close inspection.

The incident was reported by telephone to the National Response Center, report II2727 and the Michigan PEAS on February 24, 1989.
