| Event Description | The following report was received via e-mail from the State of Texas Department of State Health Services Radiation Branch:
On August 13, 2010, the Agency [Texas Department of Health] was notified by the licensee that on July 16, 2010 they discovered that the shutter on a TN Technologies Model 5205 nuclear gauge containing 100 millicuries (original activity) of Cesium (Cs) - 137 was inoperable. The gauge shutter was stuck in the open position, which is the normal operating position. There was no additional exposure risk to any individual due to the failure. The licensee discontinued the use of the gauge and contacted the manufacturer to schedule the repair of the gauge shutter. On July 29, 2010, the manufacturer's technician arrived at the plant to repair the gauge. The technician found a build up of corrosion had occurred preventing the gauge shutter from operating properly. The technician advised the licensee that the gauge and source should be replaced due to the corrosion. The gauge was removed from the vessel on July 29, 2010. The technician secured shielding over the source. No significant exposures were received during the source/gauge removal. A leak test of the source was conducted and the results were below the limit. The licensee is making arrangements to dispose of the source and gauge. Additional information will be provided as it is received in accordance with SA 300. Texas Incident #: I - 8771 |
