Plug Welds in Unit 2 Spread Room File No. 903.9
Dear Mr. Bangart:
1.
Based on examination by David Holmgren, we agree that there are indications of welded repair on CTH-8057, CTH-8058, and CTH-8073.
These indications have been documented on Nonconformance Reports M-84-01230, M-84-01231, and M-84-01232 respectively.
2.
There is no documentation available to indicate that these repairs were approved or properly inspected in accordance with applicable procedures.
3.
To assess the extent of this type of unauthorized repair, TUGC0 will perform a visual inspection, using methods similar to those described by Mr. Gilbert in the Addendum to NRC Staff Testimony dated April 24, 1984, of a statistically representative sample of the cable tray hangers in the Unit 2 Cable Spread Room. Corrective action will be taken, as dppropriate, in aCCordance with estdbilshed procedures.
4.
A program was in place which required repair instructions and subsequent QC inspection. Our records indicate that this program was being followed in most instances. We do not know why this deticiency was not detected and dispositioned per established QC procedures.
Our QA program did not identify and correct this deficiency because the only way to have discovered its existence would have been to make the same extensive type of examination of these individual supports as made by Mr. Gilbert.
There was no apparent programmatic breakdown which would have led QA personnel to take these these extraordinary steps.
Very truly yours, Y,=
