DOCKET NO: 50-287 UNIT: Oconee Unit 3 DATE: 8/15/80 NARRATIVE

SUMMARY

MONTE: July, 1980 .

Oconee 3 began the month of July in heatup. During heatup, a reactor trip was experienced on July 3 at 0818 due to a feedwater swing while unblocking the main feedwater valves. The reactor was critical again and the unit on line at 1204 the same day. After necessary holds for maintenance problems and planned tests, the unit reached near rated power at 1315 on July 5.

On July 10 at 1914, the unit tripped due to a MSRH high level indication. It was returned to service on July 11 at 0031. Another trip occurred at 0835 from a power imbalance. The unit was in service again at 2020 and increasing in power. Near rated power was reached on July 13 and continued the remainder of the month.
