E7018 Electrode Determined to be of Non-ferrous Material '( , r 4 nav On February 18, 1982, Illinois Power notified Mr. Ken Ridgeway, NRC Region III (Ref: IP letter, Y-7607 dated

, 2/18/81) of a potential reportable deficiency per 10CFR.50.55(e) concerning the E7018 electrode found to contain non-ferrous material. Our investigation of this matter has not been com-pleted, and this is an interim report per 10CFR50.55(e)(3). .

A STOP WORK was immediately initiated to cease all weld-ing on site when it was discovered that improperly labeled electrode may have been used in ferritic welds. All E7018 electrode was withdrawn from the field and collected together l

with all other E7018 electrode on site to perform an investiga-tion to determine the extent of the problem. In parallel with this action samples from the electrodes in question were analyzed by an inderendent test laboratory and found to be 309 S.S. wire coateo with iron powder / low hydrogen flux, normally. utilized with E7018 electrode.

All travelers for in-process welding utilizing E7018 electrode were withdrawn from the field and reviewed for t

determination of use of electrode from the lot which contained the improperly labeled electrodes. Welds which consumed electrodes from the suspect lot are in the process of being tagged. Subsequently all welding was restored utilizing electrodes from a new vendor except for those welds identified to have consumed electrodes from the suspect lot.

r:

'/ Page 2 Since E-7018 electrode was used on various piping and structural welds, a verification will be conducted in order to confirm that the suspect electrode was not used in other plant structures. Currently, the NDE method to be employed for conducting such a-verification is being evaluated.

We anticipate that we will need approximately 90 days to complete our investigation of this matter. At sucb time we hope to be able to provide further details and conclusions regarding the reportability of this potential deficiency.

Very truly yours,
