R. Stephens (616) 465-5901 May 4, 1989 lof2 MONTHLY OPERATING ACTIVITIES - APRIL 1989 HIGHLIGHTS The unit entered the reporting period at 94% rated thermal power (RTP).

A power reduction to 65K RTP was underway to remove a condenser half for inspec-tion for possible tube leaks.

During the inspection the total of 1 tube was replugged and 50 tubes rolled in the condenser.

Following the inspection the unit was taken to 100K RTP which was achieved later the same day 4-1-89.

On 4-8-89 a power reduction to to 55%

RTP to remove the main feedpumps to check their condensers for possible tube leaks.

During the inspection there were no tubes found to be leaking, but a diaphragm was replaced along with some bolts on the manway.

Following the inspections the unit was returned to 100K RTP.

On 4-14-89 power was again reduced to allow the removal of the main feed pump to check their condensers for possible tube leaks.

During the inspection 1

tube was replugged on the "W" main feedpump condenser and 2 tubes were plugged on the "E" main feedpump condenser.

Following the inspection power was returned to 100K RTP.

On 4-21-89 power was reduced to 56K RTP to again check the main feedpump condensers.

The inspection resulted in 1 tube being re-plugged on the "W" MFP and 2 tubes on the "E" MFP.

A power ascention was begun to return the unit to 100%

RTP.

Full power was achieved on 4-23-89 and remained there for the balance of the reporting period.
