Oconee Unit 1 DATE:
07-17-78 NARRATIVE
SUMMARY
MONTH: June, 1978 Oconee 1 began the month of June at 95% power due to a high condensate flow condition exce.. ling normal capacity of the polishing demineralizer cells. On June 1, 197P, at 16:04 hours, the turbine tripped due to a high level in the
'T "B" MSDT caused by the failure of valve HD-28 (emergency dump valve) to function properly.
The reactor tripped from high pressure. The unit was returned to service at 22:10 hrs. and after normal holds, reached near rated power on June 3, 1978. On June 15, 1978, the unit was removed from service because of packing leakage on valv? RC-16 (pressurizer sample line). The valve was replaced and the unit returned to service on June 23, 1978 at 12:08 hrs. After xenon holds, near rated power was reached on June 26, 1978.
