Illinois via email:
The Radiation Safety Officer for Americas Styrencs, LLC, called to report that on September 10, 2019, they were conducting a routine six month shutter check on a Texas Nuclear Model 5180A device and determined that the shutter was stuck in the open position. The device is 40 years old, and it originally contained 2 Curies of Cs-137. The gauge is located on a vessel which is still in active use and is exposed to ambient weather conditions. The gauge is located approximately 10 feet overhead and the beam path is not a routine work location for day-to-day operations. They will contact Thermo MeasureTech to schedule service on the device and apprise the Illinois Emergency Management Agency (Agency) on the service date. Since this device operates continuously, it will continue to function and not interrupt their operations. An Agency inspector arrived on the scene on the same day to confirm that the device was in a safe configuration for continued operations.
