'IEIrT) INPERIM REPORP Description of Deficiency on four separate occasions between June and December 1980, employees of TVA's Division of Construction discovered defects in welds by visual enmination after the subject material had been released from the vendor shop by TVA's source inspectors.

L All of the four occasions were handled as individual nonconformance reports (NCR's). 'Ihe specific safety implication of each NCR will be addressed in that manner. However, this NCR was written to address the generic l implications associated with a breakdcwn in the quality system at the source inspection level.

Interim Progress TVA is scheduling a special team of Quality Engineering Branch employees to survey each site for the purpose of:

1. Reviewing weld defects associated with vendor-supplied equipment,

2. Determining the cause or reason the defects were not discovered by source inspection, and

3. Developing appropriate corrective actions.
