SECOND INTERIM REPORT 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 examination after the subject material had been released from the vendor shop by TVA's source inspectors.

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

Interim Progress TVA is finalizing the study to determine the generic implications of the condition and develop corrective action.
