The following was excerpted from an email received from the state of South Carolina:
On January 5, 2018, the licensee called [South Carolina Department of Health and Environmental Control] to provide notification of stuck shutters on 2 sets of three-rod Berthold Model LB300L fixed gauging devices. The shutters were stuck in the open position. The gauging devices contain Co-60 in amounts of 0.11, 0.41, and 1.81 milliCuries in one and 0.189, 0.5, and 1.50 milliCuries in the other. The [licensee's] Radiation Safety Officer found the shutter stuck in the open position on November 6, 2017 and the licensee notified the State on January 5, 2018. The licensee called Berthold to come out to evaluate corrective measures on the shutter mechanisms. Berthold technicians came to the plant on December 19, 2017. After being informed of proper procedures on reporting requirements, the licensee stated that a written report will be sent within 30 days of the event.
Updates to this event will be made through the
NMED system.
