The following is a summary of a report received via fax:
This [interim report is being provided] in accordance with 10 CFR Part 21.21 concerning the supply of 0.5 inch Stainless Steel Tubing to the Duke/Progress Energy Brunswick Nuclear Generating Station. Mackson Nuclear subcontracted Tioga Pipe to supply the tubing. Tioga Pipe in-turn subcontracted Summerill Tube; in which Summerill Tube procured the tubing commercially utilizing the provisions of ASME Section III, NCA 3855.5. However, Summerill failed to properly implement the requirements of NCA-3855.5(a)(2) in that a product analysis of each piece of unqualified source material was not performed.
Tioga Pipe does not have the capabilities to conduct an evaluation of the defect to determine if a substantial safety hazard exists in the tubing supplied to Duke/Progress Energy. As such, Tioga cannot provide a timeframe as to an expected completion date, and is relying on the licensee, Duke/Progress Entergy, to make the final determination.
