On April 23, 2012, a Notice of Violation was issued to Global Nuclear Fuels – Americas, LLC for a Severity Level III violation involving a significant delay in the Criticality Warning System (CWS) activation process which resulted in the failure of the CWS to be able to initiate an immediate evacuation of the facility, had an evacuation been required while special nuclear material operations were being conducted, as required by Safety Condition S-1 of its license. Specifically, between May 3 and July 17, 2011, the CWS exhibited a three minute delay before the alarm horns would sound. No actual consequences resulted from this violation because there were no incidents requiring an evacuation during this time period.
