| Title | Agreement State Report - Stuck Open Shutter on Fixed Gauge |
| Event Description | The following report was provided from the State of Texas via Email:
On August 5, 2014, the licensee notified the [Texas Department of State Health Services, Investigation Unit, Radiation Branch] Agency that it had discovered it was unable to close the shutter on a Berthold model LB300ML fixed nuclear gauge that contains a 2.5 milliCurie cobalt-60 source. The licensee stated it had experienced a loss of power on August 3, 2014, that resulted in the loss of control of the flow of molten steel. The licensee stated when it was able to get to the gauge on August 5th and discovered that some steel had spilled onto the top of the gauge's knobs and prevented shutter closure. The licensee stated that the source housing was not damaged and the source had not been compromised. The licensee also reported it has not yet been able to get to the shutter on a second gauge (same model and source) due to the steel spillage. It is anticipating the steel will be cleared within the next 1-2 days so it can make a determination on the status of the shutter on the second gauge. The gauges normally operate with the shutter in the open position. There have been no overexposures as a result of this event. Due to the location of the gauges/sources and the steel spillage, there is no risk of overexposure. The licensee stated it had already scheduled a routine service call for August 7th, for its gauges. The licensee will have the technician make needed repairs to the disabled gauge(s) while they are at the facility. More information will be provided as it is obtained in accordance with SA-300. Texas Incident #: I-9218
On August 6, 2014, the licensee notified the Agency that it was finally able to access the second gauge, Berthold LB300ML containing 2.5 milliCurie cobalt-60 source, referred to in the initial report. The licensee reported that the shutter on this second gauge was binding (cause unknown at this time) and they were unable to close it. The gauge normally operates with the shutter in the open position. There have been no overexposures as a result of this event. Due to the location of the gauges/sources and the steel spillage, there is no risk of overexposure. The licensee will include this shutter for evaluation/repair when the service technician comes to its facility on 08/07/2014. More information will be provided as it is obtained in accordance with SA-300. Notified R4DO (Werner) and FSME Events Resource via email. |
