SUMMARY
OF OPERATING EXPERIENCE
~
UNIT TWO DECEMBER, 1982-
~12-l'to-12-4 Unit Two entered the month operating at a power level of-478 MWe. By the afternoon of the 3rd heavyirains caused the swelling of the river and subsequent flooding in the upper levels of the Crib House.
12-5 to 12-17 After the river level subsided the Unit was again returned to operation and reached a power level of 468 MWe. An increase in off-gas has been noted for several days. A cracked weld was discovered on 2D3 Feedwater heater emer-gency spill line to the condenser.
12-18 to 12-23 Following a weld repair, the Unit was quickly returned to power, but several days later the Unit was scrammed due to low air pressure to the Scram valves.
12-23 to 12-31 After air pressure was restored, the Unit was again returned to power and continued through the end of the period.
For this month, Unit Two had a capacity factor of 44.54%
and an availability of 83.75%.
