The following report was received from the State of
Virginia via email:
On May 23, 2018, the Radiation Safety Officer of the licensee reported to the Agency [Virginia Office of Radiological Health] that an on-site technician noted that the computer system had issued a 'Wheel Stuck' alarm, and found that the shutter of the fixed gauge could not open when ordered to do so due to a broken part in the shutter positioning mechanism. This was discovered on May 19, 2018.
The gauge is a Valmet Automation Model BWM-T, serial number 18500173, with two 400 milliCurie Krypton-85 sources (IUT Model KR85.1, capsule ID number X9093). The device was repaired by HOOSIER Technical Services, and is currently working correctly.
More information has been requested by the Agency regarding the root cause of the problem. This report will be updated when any additional information is received.
