Prior to the visual discovery, the following NDE's were completed as satisfactory on the subject weld, e RT Inspected to ASME III, August 13, 1980 e PSE UT Test Per ASME XI, August 20, 1980 o PWHT Completed, September 24, 1980 II. Approach To and Status Of Proposed Resolution

-Bechtel Construction is currently taking the necessary steps to investigate and correct this indication by alternately perform-ing a light grinding operation followed by a PT inspection until the indication is removed.

III. Projected Completion of Corrective Action and Submittal of the Final Report Evaluation of this condition and submittal of the Final Report is forecast to be completed by March 24, 1982.
