SUMMARY

OF OPERATING EXPERIENCE JUNE 1980 At the onset of the June 1980 reporting periou, power generation was continuing at 85%. Reactor Rated Thermal Power (38 MWe-Net).

This operating level has been scheduled to extend core life to stretch optimum production until refueling becomes necessary.

On June 2,198 0, the reactor was shutdown-in preparation for operator license examinations, which were conducted on June 3rd.

The reactor was first taken critical at 0924 arel the last test critical was achieved at 1139.

At 2110 on June 3rd, the turbine-generator was resynchronized to the DPC grid.

Power. escalation continued until June 6th when 85% Reactor Rated Thermal Pc.ier (38 MWe-Net) was achieved.

Power generation continued at this level until June 21st.

At 2121 on June 21st, the reactor sas manually shut down to repair a seal leak in Upper Control Rod Drive Mechanism No. 24.

The seal on Forced Circulation Pump 1A was also repaired while the plant was shut down.

At 1827 on June 28th, the reactor was brought to critical, but a scram occurred at 2038 with reactor power at 7 x 10-9 amps due to failure to upscale on Nuclear Instrument Channel No. 6.

At 2125 the reactor was returned to critical and at 2256 on June 29th, the turbine-generator was synchronized to the DPC grid.

Power escalation continued with 38% Reactor Rated Thermal Power (14 MWe-Net) being achieved by the end of the June reporting period.

Significant maintenance items performed during the June 1980 reporting period are indicated on the attached Instrument and Electrical and Mechanical Maintenance listings.
