+ sCE PPESeDENT OPtaAflONS September 11, 1979 Mr. W.C. Seidle, Chief Reactor Construction and Engineering Support Branch U.S. Nuclear Regulatory CoIraaission Region IV 611 Ryan Plaza Drive, Suite 1000 Arlington, Texas 76011 Re: (a) Docket No. 50-482 (b) GKoester letter to USeidle dated 4/25/79 (c) GKoester letter to WSeidle dated 6/20/79 Subj: Potential 50.55(e) Report Regarding Walds on G&W Pipe Assemblies

Dear Mr. Seidle:

This letter is to confirm notification, given by Messrs. Clark and Prigel to Mr. C.R. Oberg at the Wolf Creek Site on August 24, that we are increasing the scope of our investigation of a pott.ntial 50.55(e) item regarding piping assemblies furnished by Gulf and Western Energy Products Group (G&W) . As previously reported in Reference (b) and Reference (c) ,- Class II assemblies will be reworked to improve the surface condition of the welds and then will be re-radiographed. This rework has not yet been accomolished and there is nothing further to report abo'ut the Class II assemblies at this time.

However, Daniel forces at the site have found several welds in Class III assemblies (which do not require x-ray) which do not appear to meet the visual inspection requirements for Class III welds; therefore, the investigation of G&W assemblies has been expanded to include both Class II and III assemblies. All Class III assemblies are being reinspected and a Nonconformance Repo d will be initiated and processed for all welds which do not meet acceptance criteria.

j We will report further on this matter as more information becomes available.

Yours very truly,

.- /- -
