NARRATIVE

SUMMARY

OF OPERATING EXPFRIFNCE FEBRUARY 1981 At the onset of the February 1981 reporting period, the reactor was at 21% Rated Thermal Power during power escalation at the end of the refueling outage.

At 1112 on February 1, 1981, the turbine-generator was synchronized to the DPC electrical grid, but at 1119, the generator was removed from the grid, as a precautionary r.easure, since the internal spring pin for oil Circuit Breaker 25NB1, which connects the generator to the DPC grid, was broken when the switch was closed.

During the preparation for repair of the switch, an incorrect 69 KV disconnect switch was opened, which interrupted the off-site 69 KV power supply to the reserve auxiliary transformer, causing an automatic reactor shutdown at 1134.

The reactor was returned to critical at 1543 on February 1 and escalation commenced.

At 0159 on February 2, the turbine-generator was synchronized to the DPC grid.

At 0455 the generator was removed from the DPC grid as a precaution due to turbine governor hydraulic control system response problems.

The plant was resynchronized to the grid at 0715, but additional un:bbae governor control system response problems led to the generator being disconnected from the grid at 1708 on February 2 for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and 15 minutes and on February 4 at 0330 for 23 minutes.

System response improved with continued operation.

The reactor was not shut down during these turbine generator outages.

Power escalation continued until February 14, when 85% Reactor Rated Thermal Power (38 MWe-Net) was achieved.

This power level has been scheduled to extend the time period between refueling outages.

Power generation continued at this rate throughout the remainder of the February reporting period.

Significant maintenance items perforred during the February 1981 reporting period are indicated on the attached Instrument and Electrical Maintenance and Mechanical Maintenance listings.
