Title | Agreement State Report - Malfunctioning Source Shutter Failed to Close |
Event Description | The following information was received via facsimile from the State of Nebraska:
The Nebraska Department of Health and Human Services was notified by a representative of the Omaha Public Power District that a Kay Ray fixed gauge Model Number 7080 source shutter failed to close. The device contains approximately 25.5 millicuries of Cesium-137. The gauge is mounted between two fly ash hoppers approximately 20 feet off of the floor. The source closure mechanism on the gauge is connected to a handle located at floor level by a flexible cable. The closure cable is secured so that when the floor handle is operated, the control cable slides inside of the sheath opening/closing the shutter. The shutter closure cable became loose where the sheath attaches to the source closure mechanism which prevented the shutter from closing. The licensee disconnected the lower part from the cable and the on/off handle. By holding on to the lower part of the sheath and sliding the internal cable, the licensee was able to close the shutter. No personnel were exposed to radiation during this event. |
