Subject:

Report of 10CFR50.55(e) Its on Unacceptable Contractor Practice regarding Ultrasonic Testing of Flued Head Structures (#100)

Dear Mr. Keppler:

On September 9,1983, Detroit Edison's Mr. W.R. Wingfield, Quality Engineer - Construction Quality Assurance telephoned Mr. J. Konklin of NRC Region III to report on unacceptable contractor practices regarding Ultrasonic Testing (UT) of Flued Head structures.

A problem was identified concerning a site contractor's (Wismer and Becker) Ultrasonic Testing practices. The problem is inconsistent implementation of the UT procedure, inconsistency in technique utilization, and a deficiency in their Quality Control program by which known deficiencies were not reported in a timely manner.

This has affected remedial and preventative corrective action.

(i.e. Rejectable UT reports over one and a half years old had not been processed, nor had the rejectable item been repaired) .

The extent of the problem, and the safety implications have not yet been determined. An investigation is continuing.

Another report on this item, either interim or final, will be sent when further infor: nation is availabic. If you have questions con-cerning this matter, please contact Mr. G.M. Trahey, Assistant Director - Project Quality Assurance.

Very truly yours, k.-
