SUMMARY
l The Unit was in cold shutdown the entire month by order of the NRC.
Core cooling was provided by the Decay Heat Removal System.
The Reactor Coolant System was nar-i tially drained ~during the month to enable repair work to continue on Reactor Coolant i
Pump 1B.
MAJOR SAFETY REIATED MAINTENANCE i
i Repair work continued on RC-P-1B.
The cause of the initial high vibration was found to be a crack in the pump shaft which-extended through the thermosleeve pins about 200 around the shaft. The cause remains under investigation. However, a new shaft i
has been installed. Also installed were a new radial bearing cartridge, a turning vane /difusser assembly, a new impeller, and a reinstallation of the difusser adapter.
p Also found during the disassembly was significant impeller erosion that is thought to have been a result of cavitation. The exact cause of this is unknown.
1 l
ISI inspections were completed (satisfactorily) on the pump casing, 16 of 24 main
}
flange bolts, and on 12'of 12 #1 seal housing bolts.
The pump was rotated in the pump handling frame and the seals were reinstalled using a new #1 seal ring and runner.;
a new #2 seal ring, a new upper seal housing, and new #3 seal ring and runner.
Preventive maintenance inspections on RC-P-1B motor continued in March with the 1
overhaul and reinstallation of AC and DC lift pumps / motors and backstop oil numps/
j motors.
The upper and lower guide bearings were removed and disassembled and insula-tion checks were performed on the motor.
ISI inspections on the motor flywheel were i
satisfactorily performed and new upper and lower guide bearings.were installed. The oil system was refilled and temporary power was suonlied to the lift pumos while the
]
pump was rotated.
Motor to pump alignment and UT inspections on RCP-1A, C, and D were commenced.
No' UT indications were found on the three pump shafts and only the C ouma required minor 4
alignment.
Inspections of the remaining three pumps using fiber optics through 30 foot sections of the pump cold legs has resulted in concluding there is no degredation j
of the other impe11ers.
Reassembly of RC-P-1B is currently in progress with completion and testing e.:pected l
during April.
i i
Incal Leak Rate Testing continued during the month of March with the east and west fuel transfer tubes, reactor building equipment hatch, three penetrations,_and sixty-four valves satisfactorily tested.
l Core Flood valve CF-V-1B (pressure seal leak) completed during the month.with the re-assembly of the valve and reinstallation of the operator.
Testing will be nerformed l
at a later date.
