SULJECT': Investigation of Rejected Radiographs j Zic:mer Nuclear Station (C. G. & E)

Moscow, Ohio

Dear Mr. Milan:

This is to confirm the information received to date concerning the subject radiographs as a result of our meeting at Nuclear Regulatory Cocsission District III offices in Glen Ellyn, Illinois on April 30, 1981, and by telephone cot:munications from said office.

We are proceeding with and conducting this investigation in direct response to your request for assistance dated April 29, 1981.

It is our intent to be of service'and work in close cooperation with your staff on this matter.

A brief synopsis of the problem to date is 'as follows;

1. 600 radiographic films of NDT shop fabricated piping supplied to the Ziz=ner plant site by Pullman Power Company was reviewed by Nuclear Regulatory InvestiSators.- Approximately 180 of these films were rejected as being unacceptable since it was obvious the penetrameter had not been shimed in accordance with the applicable ASME Section III, Code 1971 edition, Appendix IX, paragraph 3334.4.

k 2. The film in question originally had been checked by the following organizations; .

(a) Pullman Power (b) Hartford Steam Boiler Inspection (shop)  :-

(c) NES .

(d) Cincinnati Cas & Electric (e) Bartford Steam Boiler Inspection (field)

. \ '

All of the above examiners found the film acceptabic, and no one co: rented on the lack of shiming.

. Mr. Milen

, 3. The NRC commented that.cther portions of the radiographic procedure used to make the radiographs in question was not followed. As an example shims were used in some .

. instances when not needed or called for, while in other

_ instances where shims were called for, or required,.none

. were osed. -

4. Testimony was given that if film density variations didn't exceed the -15 or +30 tolerances in the area of interest the film should be acceptable. This refers to an entirely separate code requirement and we are in agreement that it has no bearing on the Code requirement that thickness filned through the penetrameter should be equal to the maximum thickness filmed in order that 2% sensitivity is assured.
5. The films in question could have indications of a size equal to the distance of the unproven sensitivity, and go undetected.

. 6. Pullman Pouer has asked for time to develop an acceptable plan for resolution of these apparent nonconformities.

A meeting with Pullman, Hartford Steam Boiler, C. G. & E.,

NES, and the Nuclear Regulatory personnel scheduled for May 18, 1981 has been postponed. As further developments come to our attention we will keep you advised.

It might be desirable to schedule a joint state of Ohio and National Board inspection at the site whereby we could personally view the radiographs in question along with the procedures used.

If you would like our participation in this type of inspection, it would be in ord'er for you to advise C. G. & E. the nuclear owner of your desire in this area, and ask that they make the appropriate arrangements with National Board so we might participate and assist you in the investigation.

Dear Mr. Borg=as:

We have reviewed your proposal for corrective action of the subject deficiency as outlined in your letter of August 27, 1981 and find it to be ac:eptable s-ith one minor exception.

Your pro:edure 6.11 indicates that you will be re-radiographing to IGS procedure 83A3891, using as nearly as is feasible the original technique.

This is not a:ceptable and is not in accord with the agreements reached durit; our last r.ceting. It was our understanding the original Pullman Power radiographic procedures would be used. If they are not going to be used, then s'so s-ill determine when it is not feasible to use same, and what critaria will be used in making that decision? How do you define "as nearly as is feasible" in this particular situation?

We co= mend you for the fine cooperative attitude, and progress which you have ade in the resolution of this problem. We trust the necessary correctiva action to bring this problem to a satisfactory conclusion will present na serious difficulty.

If va _;.y be of any help, please feel free to contact us at any time.

( Very truly yours, l
