The core unloading began again on 4/26/84 es Technical Specification Amendment 62 was rocoived which allowed the removal o.? the last thirty fuel assemblies from the vessel with only one sourco rango instrument operable.

The core unloading was then completed on 4/26/84.

Diesel Generator AB failed twice this reporting period as it tripped on overspoed both timos.

In accordance with Technical Specification 4.8.1.1.2a, the testing frequency of both Unit 2 Diosol Generators is now savon days.

As the reporting period came to an end, all fuel was in the spent fuel pit waiting to be moved into the vessel.

Total electrical generation for the month was O MWII.

The limitorque was disassembled replacing the declutching shaft, tripper bar and fingers, tripper bar spacer, tripper bushings, repacked with grease and reassembled. Functional testing was performed satisfactorily following replacement of the control transformer.

M-2 Check valve FW-132-1, auxiliary feedwater to #1 steam gen-erator was reported to be leaking by. Machined the seating surfaces of the clapper and lapped the valve seat. The valve was reassembled and returned to service following re-pairs.

M-3 Unit 2 cast centrifugal charging pump cladding was found to have cracks and/or. indications. The indications were re-moved and cracks were rewelded.

M-4 The #4 main bearing on the Unit 2 CD Emergency Diesel was inspected and replaced. Bearing replacement was required due to both bearing halves showing evidence of movement.

M-5 Performed 18-month surveillance inspection of the Unit 2 CD Emergency Diesel. Minor discrepancies were observed and corrected.

M-6 The west residual heat removal pump was removed from service for repair of the leaking mechanical seal. The pump was disassembled, the seal was inspected and adjusted for proper seal surface contact. The pump was reassembled, tested and returned to service.

M-7 VCR-205, upper containment purge supply was observed to be leaking by excessively. The valve was removed from service and sent out for repairs. Functional testing was performed satisfactorily after reinstallation.
