| Title | Agreement State Report - Fixed Nuclear Gauge Stuck Shutter |
| Event Description | The following information was received via E-mail:
On May 10, 2016, the Agency [Texas Depart of State Health Services] received notification from the licensee's radiation safety officer (RSO) that the shutter on a Thermo Fisher Scientific Model 5176-SN B2578 density gauge, containing a 500 millicurie cesium-137 source SN MA3200, was found open during inventory/operational checks. It appears the weld had failed on the gauge. Open is the normal operating position of the gauge shutter. The gauge does not create an exposure hazard to the licensee's employees or a member of the general public. The licensee has contacted the service company who will inspect the gauge. Additional information will be provided as it is received in accordance with SA-300. Texas Incident #: I-9399
The following was received from the State of Texas via email: I-9399, EN51916 is retracted. The manufacturer inspected the gauge and shutter. All components were fully operational. The transmitter in the density detector failed, giving an erroneous reading on the meter. The licensee incorrectly assumed it was due to a broken shutter. Notified R4DO(Kramer) and NMSS Events Notification via email. |
