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 crimping process and certification of circuit breaker wiring was unavailable. With these deficiencies it is possible that installed equipment could differ from j that used for IEEE 323/344 qualification.

BBC has rewritten part of their Quality Assurance Manual to address special processes and bring such activities into compliance with 10 CFR 50, Appendix B. BBC has revised its procedures to include

(

controls on welding and crimping activities and has provided certifi-l cation on circuit breaker wiring. Equipment fabricated prior to the audit and affected by the aforementioned activities has been identified on nonconformance reports. Work by PSI and BBC is continuing in an effort to close out the nonconformance reports.

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 July 15, 1983.
