TVA Contract 76K72-820117 Our Cont. #2550 Reactor Pressure Vessel Shield Wall Structural Steel Hartsville Nuclear Plants (1.2 i -X2 0)
Phipps Benci Nuclear Plant (X41, X22)
Gentlemen:
We wu advised by phone on April 25, 1979 that - 'r customer TVA was sending you a report concerning material fabricated by our firm. During our conversation TVA's representative, Mr. Terry Tyler, suggested that we should also contact your office by phone and aubmit our written report in accordance with Paragraph 21. 21. On April 26, Ic 9 we contacted your Mr. Richard McGaughy in the Philadelphia office of N. R. C. and on his advise we are submitting this report to vour office.
Our firm has fabricated and shipped one Reactor Pressure Vessel Shield Wall Unit to TVA's Hartsville Nuclear Plant in Hartsville, Tennessee. This unit was shipped to the site in 16 segments which are being assembled and welded together by TVA. During the assembi of the first tier, TVA discovered defects in some of the vertical joints prepared for field welding.
During the fabrication of the shield wall, several field weld joints, which were to be cut at 22 were incorrectly cut to 45 Whan our quality assurance manager was made aware of the situation by one of his inspectors, he determined this to be a non reportable shop error and advised the shop to correct the error by welding and grinding to the required profile. In accordance with the contract specifications, all butt welded joints are to be radiographed. Since any defects in this joint would be discovered during radiography, no safety hazard was c r e at e d.

j The corrective action taken is as follows:
1 We have authorized TVA field to radiograph all joints that were cat in-correctiv and repaired by welding.
2 We have authorized TVA field to make the necessary repairs.
3 We have fabricated a metal template which is being used in our shop for the layout of all future bevel cuts to eliminate the recurrence of the error.
If you require any additional information, please contact us immediately, a
Very truly yours, INDUSTRIAL ENGINEERING WORKS
