M-2 MM0-210, No.1 steam generator stop valve test valve had a packing leak. The leak was sealed by furmanite injection. The valve was subsequently disassembled, repaired, reassembled and repacked.
M-3 The CD diesel generator shaft-driven fuel oil pump had a leak at the pump suction. Replaced the pump.
M-4 Upon disassembly of the West centrifugal charging pump, an in-spection revealed pump casing cladding defects. The defects were excavated and welded. The surfaces of the welds were blended. Required NDE was completed.
M-5 Inspected No.1 reactor coolant pump seals. Replaced all seals, all runners and No. 1 seal insert.
M-6 The West RHR pump inboard seal was leaking. Replaced the pump mechanical seal.
M-7 Engineered safeguards features supply fan, HV-AES-2, motor burned up due to a shorted winding. Replaced the motor and had the fan functionally tested.
M-8 CM0-429, CCh' outlet valve from the West RHR heat exchanger was leaking by. Replaced the valve and had new valve tested.
M-9 Radiation monitor sample containment isolation valve, ECR-32, i
failed to meet Type C leak rate test criteria. Lapped the valve seats and cleaned the valve internals. Had the valve i
retested.
M-10 Containment' isolation valve, DCR-601, from the containment sump to the waste holdup tank failed to meet Type C leak rate test criteria. Replaced the valve diaphragm and had the valve retested.

- Safety injection containment isolation valve, ICM-265, had a body-to-bonnet leak. Replaced the valve seal ring and had the valve tested.
M-13 Ice condenser drain header containment isolation valves, DCR-610 and 611, failed to meet Type C leak rate test criteria. Re-placed the valve diaphragms in both valves and had valves re-i tested.
M-14 The steam side manway of No. 2 steam generator was leaking. Re-paired a small steam cut on gasket seating surface by welding and reinstalled manway cover.
M-15 Radiographic examination of safety injection system check valve, SI-152S, indicated the presence of the original valve disc in the outlet side of the valve. The valve was disassembled and the "old" disc was removed.
(A new disc had been installed in October,1981. ) The valve was inspected and reassembled.
M-16 Nitrogen system containment isolation valve, N-160, failed to meet Type C leak rate test criteria.
Inspected the check valve, cleaned the valve seats and had the valve retested.
C&I-l Critical control room power automatic bd; transfer occurred from normal to emergency power feed. Cause of the transfer was found to be a defective diode in the CRRP inverter, which blew a 70 amp fuse. Replacement of the diode and fuse returned the inverter to operation on the " normal feed".
