SUMMARY

OF OPERATION EXPERIENCE June 1986 The month of June began with the unit at hot shutdown.

The main unit Number 11 Bearing repairs were completed and the unit wa s on turning gear by 6 June 1986:

The six secondary sa fetie s, which had been repaired, were also returned to full operability by this date.

Prior to taking the reactor critical, it wa s detemined that 21 Battery Cha rger was not ope ra ble.

This constituted a limiting condition for ope ra tion (L.C.O.)

which precluded criticality until repairs to the battery charger returned it to full operability.

A second L.C.O., which precluded criticality at this time, wa s the inoperability of two of three cha rging pumps.

1 Both L.C.O.s were cleared and the reactor was taken critical by 1555 on 7 June 1986.

The unit was synchronized to the bus at 0438 on 9 June 1986, following slight delays caused by Main Boiler Feed Pump Oil System water ontamination. Power escalation continued throughout the day.

Manual Reactor Trip followed by automatic Safety Injection occurred on 9 June 1986.

The Reactor Trip was ordered upon trip of the single operating Main Boiler Feed Pump.

The Safety Injection was the result of circumstances which the protective circuitry sen sed as a situation requiring safegua rd s actuation.

All protective featu re s functioned per design.

/

Repairs to Main Boile r Feed Pump Bea ring Oil System were pe rformed to eliminate the root cause of Reactor Trip and the unit was retu rned to service at 0507 hours0.00587 days 0.141 hours 8.382936e-4 weeks 1.929135e-4 months on 11 June 1986.

Powe r ascension to 90% wa s commenced subject to applicable fuel soak limitations.

The unit was removed from service at 2229 hours0.0258 days 0.619 hours 0.00369 weeks 8.481345e-4 months on 13 June 1986 due to rubbing between Main Turbine shaft and the coupling guard betw en #22 and 23 LP Turbine. The guard was removed and the unit returned to service at 0715 on 14 June 1986.

The Reactor was brought to 90% power by 0330 hours0.00382 days 0.0917 hours 5.456349e-4 weeks 1.25565e-4 months for final physics testing.

Indian Point 2 attained 100% Reactor Power on 20 June 1986 following physics testing at 90% power.

Reactor power was reduced to 75% when 22 MBFP was removed from service on 25 June 1986.

The feedwater regulating valve for #24 Steam Gene rator developed problems which dictated a fu rther load reduction to affect repairs to the valve.

l

A Reactor Trip from 45% power on 25 June 1986 was caused by a trip signal f rom the independent electrical overspeed protection circuitry.

The unit was returned to service on the morning of 26 June 1986 and attained 100%

power by 1500 that day.

The month ended with the unit at 100% power.

Fine tuning of the Main Turbine Genera tor was in progre ss in an attempt to increa se unit efficiency.
