Oconee 3 DATE:

August 15. 1985 NARRATIVE

SUMMARY

Month:

July 1985 Oconee Unit 3 began the month at 100% power but was forced to reduce power on July 2 when the 382 Reactor Coolant pump indicated a low oil level. Oil was added and the unit returned to 100% on July 4.

On July 14 the unit was forced to reduce power again because of low oil level on 3B2 Reactor Coolant pump.

The decision was made to leave this pump out of service and operate with 3 loops instead of 4.

The unit reached 74% power on July 15'and operated at that level until July 23 when a defective circuit in the Integrated Control system caused a runback, feedpump trip and then a Reactor trip. The unit returned to service that day and operated at 74% power for the balance of the month.

Personnel Exposure For the month of June, 4 individuals exceeded 10 percent of their allowable annual radiation dose limit with the highest dose being 1.510 Rem, which represents approximately 12.6% of that person's allowable annual limit.

2.

The total station liquid release for June has been compared with the Technical Specifications maximum annual dose commit-ment and was less than 10 percent of this limit.

The total station gaseous release for June has been compared with the Technical Specifications maximum annual dose commit-ment and was less than 10 percent of this limit.
