On June 13, 2017, the NRC issued a Notice of Violation to P4 Production, LLC, for a Severity Level III problem for violations of three license requirements addressing fixed nuclear gauge activities that resulted in unnecessary radiation exposure to two members of the public. Specifically, on November 18, 2015, June 15, 2016, and September 27, 2016, the licensee permitted contract workers to perform fixed nuclear gauge installation and dismantling without the required training. Additionally, the source was not shielded as required and resulted in a contractor's extremity coming into contact with the radiation beam. The licensee failed to ensure that any employee or contractor who was working on or near a nuclear source complete required coordination with the plant RSO, who did not review the circumstances of the work to be performed, evaluate any exposure-related safety or health concern, or take preventative measures when dosimetry readings exceeded 2 millirem per hour.
