On May 13, 2016, the NRC issued a Notice of Violation and Proposed Imposition of a Civil Penalty in the amount of $7,000 to Novelis Corporation for a Severity Level III violation. The violation involved the deliberate repairs of a nuclear gauge that were not permitted under the terms of Novelis’ NRC License. Specifically, on September 12, 2014, the licensee replaced a pneumatic cylinder that controls the position of the shutter, and on September 13, 2014, the licensee adjusted the shutter control mechanism of a nuclear gauze. These repairs were specifically prohibited by conditions of its license.
