SUMMARY

OF UNIT 1 OPERATING EXPERIENCE FEBRUARY 1983 2/1 At the beginning of this reporting period Unit I was operating at 900 MWe with the reactor at 100% power.

2/5 The unit was taken off the line at 1312 in accordance with Technical Specifications due to the failure of two control element assembly position indication channels.

2/7 The reactor was brought critical at 1232 and the unit paralleled at 1545.

2/8 Load was increased to capacity (900 MWe) at 1320.

2/9 Started decreasing load at 1110 to investigate saltwater leakage into the main condenser. Load was decreased to 800 MWe at 1450 when indications of saltwater leakage disappeared. Resumed full load operation (900 MWe) at 1700.

2/12 Decreased load to 715 MWe at 1030 to clean main condenser waterboxes. Load was increased to capacity (900 MWe) at 1500. At 1900 load was reduced to 880 MWe to investigate saltwater leakage into the main condenser. Load was increased to 910 MWe at 2100 when indications of saltwater leakage disappeared.

2/16 At 2230 load was reduced to 815 MWe to investigate saltwater leakage into the main condenser.

2/17 Load was increased to 910 MWe at 0500 when Indications of saltwater leakage disappeared. At 0600 load was reduced to 820 MWe to investigate saltwater leakage into the main condenser. Load was increased to 910 MWe at 1400 when indications of saltwater leakage disappeared. At 1700 load was reduced to 840 MWe to investigate saltwater leakage into the main condenser. Load was increased to 910 MWe at 2230 when indications of saltwater leakage disappeared.

/

2/18 At 0015 load was reduced to 825 MWe to investigate saltwater leakage into the main condenser. Load was increased to 910 MWe at 0545 when indications of saltwater leakage disappeared. At 0730 load was reduced to 820 MWe to investigate saltwater leakage into the main condenser. After plugging 2 condenser tubes resumed full load operation (905 MWe) at 1600.

2/27 Decreased load to 720 MWe at 0200 to test Main Turbine Control Valves.

Resumed full load operation (905 MWe) at 0700.

2/28 At 0828, the turbine tripped when the level switch on 11 Moisture Separator Reheater malfunctioned causing the reactor to trip on loss of load. The reactor was brought critical at 1315 and the unit paralleled at 1640. At the end of this reporting period, Unit I was operating at 860 MWe with the reactor at 98%

power, increasing to capacity.

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE FEBRUARY 1983 2/1 At the beginning of this reporting period, Unit 2 was critical awaiting return of steam generator chemistry to within specification. Load was increased to 220 MWe at 1830. Held at this load to allow steam generator chemistry to return to within specification.

2/2 Commenced increasing load to capacity at 0001. Load was increased to 640 MWe at 0600. At 0811 the loss of 120 VAC vital bus initiated an actuation of ESFAS. The actuation tripped the main turbine causing the reactor to trip on loss of load.

2/4 The reactor was brought critical at 1545 and the unit paralleled at 1847.

2/5 Resumed full load operation (870 MWe) at 1045. Electrical output was limited due to moisture separator reheater shell drain tank dumping to the main condenser because of fluoride contamination from weld slag.

2/11 Decreased load to 290 MWe at 1900 to clean main condenser waterboxes.

2/12 Resumed full load operation (885 MWe) at 0700.

2/18 Load was increased to capacity (900 MWe) at 1550 af ter fluoride levels reached acceptable limits in the moisture separator reheater drains allowing them to be

directed to the feedwater system.

l l 2/20 Decreased load to 760 MWe at 0115 for main turbine control valve testing.

Decreased load to 700 MWe at 0250 when one of the intercept valves failed to re-open af ter testing due to a sticking solenoid valve. Load was increased to capacity (900 MWe) at 0630.

2/28 At the end of this reporting period Unit 2 was operating at 900 MWe with the resctor at 100% power.
