The following report was received from the State of
Arkansas via e-mail:
At approximately 1127 CST on 2/28/2018, the Arkansas Department of Health [ADH] Radioactive Materials Program received a phone call from the licensee stating that during routine shutter tests the gauge shutter handle fell off and the shutter is stuck open. The gauge is a Vega America Corporation (Ohmart) Model A-2102, serial number 6997, originally containing 1.5 Curies [Cesium-137] on 4/30/1968 (calculated current activity approximately 475 milliCuries).
Discussion with the licensee indicates that the gauge is mounted on a digester, outside of normal employee traffic. It is normally open during operations and is only closed during maintenance of the digester, which is not planned. Cautionary signage is already present. The licensee representative stated that the staff will be made aware of the situation. Licensee maintenance is assessing the situation and will advise the ADH Radioactive Materials program of the plan for handling this situation.
The State of
Arkansas is awaiting a written report from the licensee and final disposition information for the
gauge. The State's event number is AR-2018-003.
