Subject:

Final Evaluation of 10CFR50.55(e) Item 131 "Weldolets Lacking Complete Chemical Documentation" Detroit Edison has completed its investigation of Item 131 and has determined that it is not reportable under 10CFR50.55(e). This item concerned five weldolets fabri-cated by Guyon Alloys Company. Item 131 was originally reported as a potential deficiency on June 27, 1984, and was subsequently documented in Reference (2).

Pursuant to the requirements of 10CFR21, Detroit Edison was advised by Reactor Controls, Inc. (RCI), a Detroit Edison subcontractor, that five weldolets lacking the chemical overcheck required by the ASME Code may have been supplied to Fermi 2. These fittings were manufactured by Guyon Alloys Company from stock material which was incompletely qualified (upgraded) under the provisions of ASME Boiler and i Pressure Vessel Code Section NCA-3867.4(e).

A review of our records revealed that three weldolets, all l with the same heat number, were actually received at Fermi 2. 1 Two of these weldolots were installed by RCI in the Main Steam System Safety Relief Valve (SRV) discharge lines.

The chemical overcheck required by ASME Boiler and Pressure Vessel Code NCA-3867.4(e) was performed by Detroit Edison's Engineering Research Department on a boat sample taken from one of the installed weldolets. This overcheck confirmed the results of the original ladle analysis. This then meets the requirements of the ASME Code. I g409280072840911 DR ADOCK 05000341 g PDR SEP17 1984 l 1l0 pEQ7
