UNIQUE REPORTING REQUIREMENTS MAIN STEAM RELIEF VALVE OPERATIONS Relief valve operations during the reporting period are summarized in the following table. The table includes information as to which relief valve was actuated, how it was actuated, and the circumstances resulting in its actuation.

Valves Description Unit Reporting Period Actuated Actuations Conditions of Events 2 01-01-85 to 01-31-85 None (4 safety / relief valves were replaced during the refueling outage and will be tested in February of 1985.)

3 01-01-85 to 01-31-85 None

SUMHARY OF OPERATING EXPERIENCE UNIT TWO JANUARY, 1985 01-01 to 01-31 Refueling outage activities continued throughout the entire period. The unit is presently scheduled to start-up in mid-March, 1985. Major work includes:

- Local Leak Rate Tests

- ISI Inspections

- ILRT Preparation

- Normal Pump (s) and Valve (s) Maintenance

- Snubber Replacements

- Clean-up Pipe Replacement

e SUMHARY OF OPERATING EXPERIENCE UNIT THREE JANUARY, 1985 01-01 to 01-14 Unit 3 entered the month operating at a level of 815 MWe and operated until January 12th, at 0101 when a Rx scram and turbine trip occurted because of the malfunction of the o'.1 trip solenoid valve during turbine weekly testing whirn caused a turbine trip on a false overspeed trip signal and a Rx scram.

01-14 to 01-31 The Rx was brought critical ou January 14th at 2125 and the turbine was placed on system January 16th at 0345.

The unit operated continuously during the remainder of the month (with notaal power reductions for weekend surveillances) reaching a power level of 819 MWe with a capacity factor of 78.65% and an availability of 86.73%.
