Licensee Investigation of Allegation

(

Dear Mr. Keppler:

This letter is in response to C. E. Norelius' letter to W.

C. Gerstner dated July 29, 1985.

This letter identified a concern with the adequacy of welding procedures and the possible detrimental effects on welds related to the letter from Ray Moss l

Associates to A. E. King of Baldwin Associates, t

Our review determined that the welder was qualified and used the correct welding procedures.

However, the welding was per-formed on the wrong welds.

This resulted in the welder being terminated for performing unauthorized work.

Documentation supporting our review will be maintained in our files for your review during subsequent inspections.

Illinois Power Company appreciates the opportunity to assist in investigating, reviewing and resolving allegations.

Sincerel

yours, r
