SUMMARY

OF UNIT 1 OPERATING EXPERIENCE - DECEMBER 1980 12/1 At the beginning of this reporting period Unit I was shutdown for its 4th scheduled refueling outage.

12/12 Completed filling the Reactor Coolant System (RCS) at 0620.

12/21 The reactor was brought critical at 1900. Commenced low power physics testing.

12/22 The reactor was tripped in accordance with the low power physcs testing procedure at 2127.

12/23 The reactor was brought critical at 0105.

12/24 Commenced rolling the main turbine at 2355.

12/25 At 0023 the main turbine was tripped due to high temperature on the thrust bearing. At 0240 the reactor was shutdown while repairing the main turbine thrust runner.

12/27 The Reactor was place in cold shutdown at 0305.

12/31 At the end of this reporting period Unit I was shutdown for repair cf lite main turbine thrust runner.

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE - DECEMBER 1980 12/1 At the end of this reporting period Unit 2 was operating at 665 MWe with the reactor at 76% power, being limited by the power coastdown procedure in preparation for the third scheduled refueling outage.

Load was increased to 735 MWe at 2200 per the power coastdown procedure (PSTP-10).

1 12/14 At 0330, Control Element Assembly (CEA) 38 dropped into the core.

Reactor power was reduced to 60%. CEA 38 was withdrawn back to its group at 0410. Load was increased to 600 MWe per PSPT-10.

12/31 Decreased load to 520 MWe at 0800 per PSTP-10. At the end of this reporting period Unit 2 was operating at 520 MWe with the reactor at 57% power, being limited by the power coastdown procedure.
