On December 7, 2006, a Notice of Violation containing six violations categorized collectively as a Severity Level III problem was issued as a result of investigations that determined that Hunt Valve engaged in deliberate misconduct with respect to applicable quality assurance (QA) requirements and deliberately failed to provide notifications required by 10 CFR 21.21, "Notification of the Failure to Comply or Existence of a Defect and its Evaluation," with regard to the manufacture and distribution of uranium hexafluoride (UF6) cylinder valves and components procured by U.S. Enrichment Corporation (USEC). The NRC Office of Investigation substantiated that Hunt Valve deliberately violated 10 CFR 21.21 and applicable QA requirements, i.e., Hunt Valve ultimately delivered UF6 cylinder valves that were not properly QA tested to a USEC facility (Paducah) and caused USEC to violate its NRC certificate and to violate 10 CFR 76.93, "Quality Assurance." A civil penalty is not being proposed in this case because the Department of Justice (DOJ) settled a civil suit against Hunt Valve by negotiating a sizeable monetary penalty of over $600,000 which significantly exceeds the civil penalty the NRC would consider for this case. Further enforcement action is not being taken against Hunt Valve's former Quality Manager and Hunt Valve's former Vice President and General Manager, Military Division, who deliberately committed the violations, based on the results of their criminal prosecutions and subsequent convictions.
