Title	Gauge Shutter CAN Not Be Closed Due to Broken Lever
Event Description	The following information was provided by the Texas Department of Health Services (the Department) via email: On April 21, 2023, the Department was notified of a gauge with a shutter that could not be moved into the closed position because the lever which moves the shutter broke off. The owner of the gauge reports the lever broke because of corrosion and vibrations. The gauge is a Texas Nuclear 5204 with 8 curies of cesium-137. It is on the side of a dredging vessel that is dredging the entrance channel in Corpus Christi in a 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of work per day operation. During dredging operations, the gauge is normally in the open position and the beam is directed inwards towards the ship. The crew of the vessel normally avoid that side of the vessel and will continue to do so. A survey of the gauge was performed and there is no change. The owner of the gauge reports that they expect the gauge to be repaired by a servicing company on May 9, 2023. The Department discussed the possibility of the vessel being docked with the gauge still in the open position and will continue to monitor the situation. Further information will be provided per SA-300. The Department will also forward this to the Florida Radiation Control Program as this is a Florida licensee operating in Texas under reciprocity.
