'/. FOURTH REFUELING STEAM GENERATOR INSPECTION During the Fourth Refueling Outage, the primary side of the tubing in

'A' Steam Generator was examined by Westinghouse Electric Corporation. The M1Z-18, multi-frequency eddy current system, was utilized for the inspection of all 3388 tubes in 'A' Steam Generator. The tubes were inspected full length, that is, from the tubesheet on the hot leg side over the u-bend region to the tubesheet on the cold leg-side. Twenty-four (24)  ;

of the 3388 tubes examined contained through-wall defect indications in excess of the BVPS Technical Specifications limit of 40 percent. >

l Concurrent with the eddy current examination described above, a visual  !

examination of the secondary-side tube sheet region of all- three steam j generators was conducted. The visual examination included the assessment I of the condition of the secondary side of the tubes in the tube lane, the l flow slot, and the peripheral areas. -A weld rod (4-inch long) was found in i

'A' Steam Generator and a piece of flexitallic gasket was found in 'B' i Steam Generator each was subsequently removed. No other tube defects were noted by the contractor, Westinghouse Electric Corporation.

The following twenty-four (24)' tubes in 'A' Steam Generator were removed from service by mechanically plugging both ends of the tube. All the tubes removed from service contained a defect in excess of the 40 percent limit.

December 16 On the 16th a steam bubble was established -

through in.the pressurizer at 1115 hours0.0129 days <br />0.31 hours <br />0.00184 weeks <br />4.242575e-4 months <br />. RCS temperature December 21 was 140'F pressure was 150 psig.
