This letter is intended to inform the U.S. Nuclear Regulatory Commission, and the affected nuclear utilities on the investigation and corrective/preventative actions associated with the Coltec-FMED Part 21 File No. 97-002. The metallurgical examination of the subject weldments, engineering analysis and the final Engineering Report has been completed. The Engineering Report states the conclusion that all the joints tested were found to be of adequate strength for the application, even though full penetration was not achieved in most cases, and that no rework of field piping is necessary. The final engineering report, which includes all appendices, is attached. Actions to preclude recurrence of less than full penetration welds includes formal training for all welding personnel on weld joint design, designation, and interpretation. This corrective action is being tracked by Coltec internal Corrective Action Request 1750, which is scheduled to be completed by September 29, 1998. Based on the final engineering report and corrective action plan, FMED considers this Part 21 completed. Sincerely, James C.
