n NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE MARCH 1981 At thh onset of the March 1981 reporting period, power generation was at 85% Reactor Rated Thermal Power (39 MWe-Net).

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

On March 9, at 1420, the reactor automatically shut down when the IB 2400-volt bus was de-energized when switching plant feeds from the reserve to unit auxiliary transformer.

The in 480-volt emergency diesel generator started and supplied the 1B 480-volt Diesel Building essential switchgear bus.

The reactor was returned a

to critical at 2331 on March 9.

At 0544 on March 10, with the reactor at 0.2% Rated Thermal Power, the reactor scramned due to high water level when the IB Reactor Feed Pump was being placed in i

service.

The reactor was returned to critical at 1948 on March 11, and the turbine-generator was synchronized to the DPC grid at 1743

• on March 12.

Escalation continued until March 15 when 85% Reactor Rated Thermal Power was achieved.

At 1440 on March 16, the generator was temporarily removed from the DPC grid as a precaution due to turbine-governor hydraulic control system response problem which involved partial opening of the main steam bypass. valve.

The reactor was not shut down during this outage.

At 1513 on March 16, the turbine-generator was resynchronized to the DPC grid.

Power generation continued at 85% Reactor Rated Thermal Power (38 MWe-Net) throughout the remainder of the reporting period.

l Significant maintenance items performed during the March 1981 reporting period are indicated on the attached Instrument and Electrical Maintenance and Mechanical Maintenance listings.
