AA'8 PUBLIC SERVICE INDIANA S. W. Shields October 20, 1983 Senior Vice President - S82-12 Nuclear Division SVP-0139-83 Mr. James G. Keppler, Docket Nos.: STN 50-546 Regional Administrator STN 50-547 U. S. Nuclear Regulatory Commission Construction Permit Nos.:

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-re'.ated switchgear. Such activ-ities are special processes and should have been controlled by procedure as required by 10 CFR 50, Appendix B, Criterion IX. With these deficiencies it is possible that installed equipment could differ from 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 activities. Equipment affected by the aforemen-tioned activities has been identified on a nonconformance report.

Further inspections have revealed that certain structural welds on some of this equipment are not specified as to type, configura-tion, and location on the fabrication drawings. BBC has therefore expanded the scope of this nonconformance report. PSI is currently working to address the additional items and ensure appropriate correc-tive action is taken.

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 2, 1984.
