NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE JULY,1980 At the onset of the July 1980 reporting period, power escalation was continuing following the June 21 - 29 outage for the repair of a seal leak in Upper Control Rod Drive Mechanism No. 24.

On July lQth, 85% Reactor Rated Thermal Power (37 MWe-Net) was achieved.

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

Power generation continued at this level until July 19th at 2214, when IB Forced Circulation Pump (FCP) tripped due to low seal injection leakoff flow, which occurred when returning the 1B Seal Injection Pump to standby.

The low leakoff flow condition occurred because the Seal Injection Pumps' bypass valves did not compensate fast enough to maintain sufficient flow to the FCP's.

The standby Seal Injection Pump had started due to a system surge

-when placing a cleaned seal injection filter back in standby'.

The 1B FCP was promptly restarted and the 1A Seal Injection Pump was successfully placed in standby on a subsequent try.

The Si;l Injection System will be thoroughly examined during the next cold shutdown.

Reactor power decreased to a minimum of 34% Reactor Rated Thermal Power (12 MWe-Net) prior to power re-escalation.

On July 21st, 85% Reactor Rated Thermal Power (37 MWe-Net) was again achieved.

Operation continued at this power level throughout the remainder of the July 1980 reporting period.

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