SUfEARY OF UtlIT 1 OPERATIflG EXPERIEilCE - jut!E 1980 6/1 At the beginning of this reporting period Unit 1 was operating at 860 MWe with the reactor at 100% power. Operated at reduced load (745 MWe) at 0100 while testing main turbine control valves.

Resumed full load operation (860 MWe)at 0300.

6/5 At 1100 load wa:: reduced to 645 MWe to investigate saltwater leakage into the main conde:nser. Load was increased to 845 MWe at 2200.

6/6 At 0130 load was reduced to 750 MWe to investigate saltwater leakage into the main condenser.

6/7 Load was increased to 825 MWe at 0930 after plugging two condenser tubes. Load was limited to 825 MWe for variable Tave testing.

6/8 At 2140 load was reduced to 715 MWe to investigate saltwater leakage into the main condenser.

6/9 Load was further reduced to 620 MWe due to shear pin failures on

12A and #12B Travelling Screens which resulted in approaching the ETS 12 F limit on main condenser circulating water AT.

At 1400 load was limited to 665 MWe to investigate saltwater leakage into the main condenser.

6/11 After plugging two condenser tubes resumed f'111 load operation (850 MWe) at 1040. At 2345 load was decrear.ed to 680 MWe to clean condenser water boxes.

6/12 Load was increased to capacity (845 MWe) at 0600. At 2230 load was reduced to 765 MWe to investigate saltwater leakage into the main condenser.

6/13 Load was further reduced to 695 MWe to limit the stress on #138 waterbox while investigating saltwater leakage into the main condenser.

SUMMARY

OF UNIT 1 OPERATING EXPERIENCE - JUNE 1980 6/14 Increased load to capacity (845 MWe) at 0900 after plugging one condenser tube.

6/16 At 1000 load was reduced to 685 fMe to investigate saltwater leakage into the main condenser. Load was increased to 845 MWe when Indications of saltwater leakage disappeared at 2145.

6/18 At 0730 load was reduced to 640 MWe to investigate saltwater leakage into the main condenser.

6/20 Located and plugged one leaking condenser tube. Resumed full load operation (845 MWe) at 0001.

6/22 At 0700 load was decreased to 640 MWe to repair #12 Sluice Gate and #12 Heater Drain Pump. Resumed full load operation (845 MWe) at 2359, 6/23 At 1045 load was reduced to 695 MWe to investigate saltwater leakage into the main condenser.

6/24 Load was increased to 850 MWe at 0830 when indications of salt-water leakage disLppeared.

6/26 At 0600 load was reduced to 670 MWe to investigate saltwater leakage into the main condenser. Load was increased to 845 MWe at 1045 when indications of saltwater leakage disappeared.

6/29 At 0030 load was reduced to 725 MWe to investigate saltwater leakage into the main condenser. Load was increased to 850 MWe at 2100 when indications of saltwater leakage disappeared.

6/30 At the end of this reporting period Unit I was operating at 850 PMe with the reactor at 100% power.
