FIRST INTERIM REPORT
-Description of Deficiency A problem has been identified at Bellefonte which involves adaptors (sized 3/4-inch and under) used to connect instrument piping to instrument tubing.
For' tube-to-pipe adaptors with TVA Mark Nos.142, 155, 158, 690, 691, 692, and 778, the TVA mark number or schedule is not affixed to the adaptor (they are not required to be), and the proper schedule adaptor required by design drawings may not have been used in all cases.
.The apparent cause of this deficiency is the lack of schedule identifica-tion on the adaptors and the fact that documentation of inspection verification of the adaptor's schedule is not required by present quality control procedures.
Interim Progress TVA has expanded the investigation of this deficiency to include 1-inch adaptors, and we will provide additional information after the investi-gation is complete.
