Dear Mr. Keppler:

On May 25, 1982, Mr. S. J. Brewer of Public Service Company of Indiana, Inc. (PSI) notified your office of a potentially reportable item as required by 10 CFR 50.55(e). During an audit at Brown-Boveri Electric, Inc. (BBC) facilities PSI quality assurance personnel discovered that welding techniques not covered by BBC's quality assurance program were being used in the fabrication of safety related switchgear. Such activ-ities are special processes and should have been controlled by procedure as required by 10 CFR 50, Appendix B, Criterion IX.

It was also discovered that no controls were placed on the terminal lug critaping process and certification of circuit breaker wiring was unavailable. With these deficiencies it is possible that installed equipment could differ from that used for IEEE 323/344 qualification.

BBC has revised its procedures to include controls on the aforementioned activities and has identified by nonconformance report all affected equip-This equipment has been checked for its conformance to the specified ment.

design and the results are being evaluated.

This letter is intended to fulfill the requirements of an interim report as required by 10 CFR 50.55(e). A further report on this item will be filed on or before March 18, 1983.

If you have any questions regarding this matter, please contact me at your convenience.

Sincerely,
