NARRATIVE

SUMMARY

Month:

March, 1986 The unit began the month at 100% power. On March 11, 1986, the unit reduced power to 88% when tube leaks developed in the Second Stage Reheaters. The.

. unit was able to return to 100% on March 15.

On March 25, 1986 the unit reduced power to 95% due to a Feedwater Heater tube leak. The Heater was isolated and the unit returned to 100% and remained at that level for the balance of the month.

March, 1986 The unit began March at 100% but reduced power to 85% on March 3, 1986 due to an oil leak on a Heater Drain pump motor. The motor and pump were replaced and the unit was back at 100% on March 7.

The unit was forced to reduce power again on March 29, when a seal failed on a Heater Drain pump. The seal was replaced and the unit returned to 100%.
