On August 8, 2008, a Notice of Violation was issued to BWX Technologies, Inc. for a Severity Level III problem involving three violations of their license. Specifically, the licensee did not (1) inspect Raschig ring-filled vacuum (RRVCs) cleaners on multiple occasions between January 28, 2008, and March 5, 2008 to ensure adequate levels of Raschig rings were present to prevent inadvertent criticality, (2) establish, prior to March 5, 2008, double contingency for operation of RRVCs to ensure that a criticality accident could not occur with only one change in process conditions, and (3) fill, prior to March 5, 2008, multiple RRVCs with well-settled Raschig rings in accordance with ANSI/ANS-8.5-1996 such that further settling was not likely during use. In this case, no actual consequences resulted because an inadvertent criticality accident did not occur.
