PKET NO: 50-270 UNIT: Oconee Unit 2 DATE: 9-15-78

- NARRATIVE S12 DIARY PCNTH: August, 1978 Oconee 2 operated at near rated power until August 8 when .1 5% reduction in power was made for maintenance on the discharge control valve for 2D2 heater drain pump (2HD-234). Near rated power was reached again.on August 9.

On August 11 power was reduced to 75% to check seal leakage instrumentation on the 2B2 RCP. The reactor tripped on flux / flow imbalance when the 2B2 RCP was removed from service because of high readings on NI channels C & D. The unit

, returned to service on August 12 and came to 30% power for the evaluation of 2B1 and 2B2 RCP seal leakage flow. This flow indicated too high for operation and the unit was removed from service for seal replacement.

The unit was on line again on August 22 with a slow power increase due to the availability of radioactive waste storage space.

While in a xenon hold at 90% power on August 24 the reactor tripped on low RCS pressure while placing spray valve (2-RC-1) in auto. The unit returned to service on August 25 and reached near rated power on August 27. This power level was continued the remainder of the month.
