Title	Safety Equipment Potentially Fails to Function
Event Description	Maintenance was being performed on a Berthold moisture analyzer in a coke bin vessel because a moisture tube inside of the vessel was damaged. Two maintenance technicians took the source holder off the vessel and then proceeded to work on the vessel. The source holder was placed nearby the work area and the source was not able to be fully retracted back into the gauge during the maintenance evolution. Maintenance then re-mounted the source holder back onto the vessel. The licensee contacted the manufacturer in order to investigate the maintenance evolution and assist estimating dosage to the two technicians. The licensee contacted Region 4 (Janine Katanic). The licensee investigation continues. * * UPDATE AT 1115 EDT ON 09/30/16 FROM DAVE MATYUS TO S. SANDIN * * * On 09/29/16 Berthold Technologies was onsite to assist in the investigation. A leak test was performed and the contractors involved were interviewed. The information will be provided to the Berthold RSO in order to estimate the dose received. NRC R4 (Dykert) was also present to observe the investigation. The licensee does not anticipate receiving the results until next week. Notified R4DO (Groom) and NMSS Events Notification by email.
