SUMMARY

The plant maintained approximately 100% until October 23,1998.

On October 21,1998 an engineer was performing a routine thermography survey. During the survey, elevated temperatures were found on the 'B' phase neutral bushing of the main transformer. After observation and evaluating the options, it was determined that the plant would be taken off-line to repair the bushing. The main turbine was tripped at 05:38 on October 24,1998 and the reactor was held at 7-8%

power during the evolution. The cause was determined to be dried grease in the connection. The bushing was repaired and the main generator was placed on-line at 03:44 on October 25,1998. The plant reached 100% power at 22:53 on October 25,1998 and remained there for the rest of the month.
