Finding

Title

Inaccurate Information Provided Regarding N2E Nozzle Weld Overlay

Description

The NRC identified an AV of 10 CFR 50.9, Completeness and Accuracy of Information, for the licensees failure to provide data to the NRC that was accurate in all material aspects. Specifically, on two occasions (October 1995, May 2000), the licensee stated that weld 1B31-1RC-12BR-E-5 had been modified with a full-structural weld overlay (FSWOL), when in fact it had only been modified with a less robust design overlay (leak barrier). The NRC approved the licensees requests/proposed alternatives in part based on the inaccurate characterization of the welds. The licensee has since installed the FSWOL and entered the issue into the corrective action program as CR 10197850. The NRC is considering escalated enforcement on the basis that had the licensee provided accurate information, it would likely have caused the NRC to reconsider a regulatory position.
