Grinding Mark on Main Steam Pipe -

Dear Mr. Madsen:

On July 1,1981, Mr. D.W. Prigel (KG&E) made a telephone report to Mr. W, Crossman (NRC) regarding a grinding mark on a main steam pipe.

The Contractor initiated Deficiency Report No. ISD7271M which documented the UT examination for wall thickness and procedures for base metal repair. A liquid penetrant examination was con-ducted prior to the base metal repair and a radiograph and ultrasonic examination conducted after the repair wCrk. The final disposition of the Deficiency Reoort has indicated that the minimum wall thickness was not violated and that the grinding mark has been repaired using the proper repair procedures. There-fo re , since there was neither a significant defect nor a break-down of QA Procedures which would adversely affect the safety of the plant, we have concluded that this matter is not reportable under Regulation 10CFR50.55 (e) .

If you require any additional information, please contact us.

Yours very truly, ggy AW j
