This was for checking and repairs of a Condenser leak.

The East Main Feed pump was returned to service and the Unit reloaded to 100/ over a 7 hour ramp starting at 1522.

10/18/80 - The East Main Feed pump was returned to service and the Unit reloaded to 100Ã power over a 7 hour8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> ramp, starting at 0215.

The Unit tripped from 100K power at 2057, a Generator Neutral Ground Relay Actuation was the cause of the trip. A Ground has been identified within the gener-ator and repairs are underway at this time.

10/19/80 - Cooldown and degassing of the Reactor Coolant System was started at 2115, for an investigation of a tube leak in ¹21 Steam Generator.

10/20/80 Unit entered Mode 4 at 0200.

10/21/80 Unit entered Mode 5 at 0200.

10/23/80 Reactor Coolant System at ', loop operation at 0938.

10/29/80- ¹21 Steam Generator was pressurized to 900 lbs. with Nitrogen to check for tube leak. There was no visable leakage at this pressure. Eddy Current Testing was performed and it was decided to plug 6 tubes.

10/31/80 "AB" Emergency Diesel was returned to service at 1350 and successfully tested to the Load Bank after Modifi-cations were made for RFC 2039.

Replaced the seat ring and gaskets.

Had valves tested.

M-2 A flow instrument flange in the RHR system between valves IRV-310 and ICM-311 was leaking. Replaced the flange gasket.

C&I-1 Main turbine stop valve B and control valve C would not test as required. The limit switch on stop valve B was inspected. A bushing in the limit switch was replaced. The proximity switch for stop valve B had vibrated loose. The proximity switch was remounted. The limit switch arm on control valve C was sticking.

The switch was disassembled and the mechanism was lubricated. A retest of the valves verified operability.

C&I-2 Main turbine stop valve C would not test to the closed position.

The coil of the control valve test solenoid failed and was re-placed. The shaft and bushing on stop valve A, open limit switch, also required replacement.

C&I-3 CD Diesel 60 psi reducing valve to the turbo charger failed to the open position, producing 100 psi pressure, opening the relief valve. The valve was removed and a spare was installed and adjusted to provide 60 psi air supply.

C&I-4 Axial power distribution monitor system, power level actuation bistable No. 1 trip setpoint was found to be 885 reactor power, while bistable No. 2 actuated at 925 reactor power. The input voltage required to trip bistable 1 was recorded as .3.81 volts with the required setpoint at 3.83 V DC. The bistable was re-calibrated to trip at the correct voltage and power level.
