SUMMARY

OF UNIT 1 OPERATING EXPERIENCE FOR OCTOBER 1984 10/1 At the beginning of this reporting period, Unit I was at 863 MWe with the reactor at 100% power. 10/2 At 1607 the reactor was manually tripped due to the reduction of main circulating water flow caused by impingement of a large number of jellyfish on the traveling screens. 10/3 ' The reactor was brought critical at 0410. The main turbine was paralleled to the grid at 1020 and escalation to 100% was commenced. 10/4 Resumed fullload operation (856 MWe) at 0930. 10/25 Reduced load to 773 MWe at 2000 due to the reduction of main circulating water flow caused by impingement of a large number of jellyfish on the traveling screens. 10/26 Resumed full load operation (865 MWe) at 0245. 10/29 Power was reduced to 855 MWe at 1045 when 12 Heater Drain Tank High Level Dump Valve failed open. Resumed fullload operation (864 MWe) at 1200. 10/31 At the end of this reporting period, Unit I was operating at 866 MWe with the reactor at 100% power. 2

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE FOR OCTOBER 1984 10/1 At the beginning of this reporting period, Unit 2 was at 868 MWe with the reactor at 100% power. 10/2 Reduced load to 360 MWe at 1555 due to the reduction of main circulating water flow caused by impingement of a large number of jellyfish on the traveling screens. 10/3 Commenced increasing power at 0530. At 0750 power was held at 600 MWe while repairs were being made to 21 Steam Generator Feed Pump. Recommenced increasing power at 1630. The reactor tripped at 1948 on low Steam Generator water level following the trip of 22 Steam Generator Feed ~ Pump. 10/4 At 1200 a Steam Generator Safety Valve lif ted and did not reseat immediately. Subsequent testing and verification of operability delayed startup until 1800. At 2044 the unit was paralleled to the grid. 10/5 Resumed full load operation at (855 MWe) at 1430. 10/6 At 0515 power was reduced to 600 MWe for maintenance on Steam Generator feed pumps. Resumed full load operation (864 MWe) at 1315. 10/10 Power was reduced to 668 MWe at 1645 hile repairs were made to 22 Heater Drain Tank Level Control Valve. 10/11 Resumed fullload operation (861 MWe) at 0650. 10/12 Reduced load to 708 MWe at 2120 due to the reduction of main circulating water flow caused by impingement of a large number of Jellyfish on the traveling screens. 10/13 Resumed fullload operation (861 MWe) at 0410.

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE FOR OCTOBER 1984 10/18 Reduced load to 778 MWe at 0050 due to the reduction of main circulating water flow caused by impingement of a large number of Jellyfish on the traveling screens. Resumed fullload operation (861 MWe) at 0510. 10/20 At 0435 power was reduced to 553 MWe for maintenance on 21 Steam Generator Feed Pump. At 1020 commenced escalation to full power. Resumed full load operation (865 MWe) at 2150. 10/21 At 1130 power was reduced to 786 MWe, when 23 Circulating Water Pump was shutdown due to excessive wear of its pump guide bearing. 10/23 Resumcd fullload operation (860 MWe) at 1820. 10/31 At the end of this reporting period, Unit 2 was operating at 863 MWe with the reactor at 100% 4 -m 3
