| ENS 49207 | 19 July 2013 05:00:00 | Agreement State | Agreement State Report - Source Disconnect | The following information was received via E-mail: On July 19, 2013, the Agency was notified by a licensee that a TFS model 5221 nuclear gauge containing two, 300 millicurie Cesium 137 sources failed to function as designed when attempting installation of the device on a process vessel. When the source was inserted into the vessel, the chain connecting one of the sources to the nuclear gauge broke allowing the source to travel to the bottom of the insertion tube. This is the normal operating position for the source. A radiation survey was conducted by the licensee indicating radiation levels to the general public were normal. The manufacturer has been contacted and is responding. It is anticipated that an attempt will be made by TFS to retrieve the source from inside of the vessel between July 20, 2013 and July 22, 2013 and then proceed to immediately repair the device. There is no additional risk of radiation exposure to members of the general public as a result of this failure. Additional information will be provided as it is received in accordance with SA-300.
