The following information was received via email from the State of Iowa:
The
RSO of Louisa Generating Station/MidAmerican located at 8602 172nd Street, Muscatine,
Iowa 52761 reported to
IDPH [Iowa Department of Public Health] at 0930
CST that at approximately 0800 [CST], the courtyard operator was performing rounds and noticed that the shutter on a
Texas Nuclear device (model # 5192, serial # B-2724, 50 mCi,
Cesium 137) in crusher feeder / hopper 1B was detached from the device and laying on the grating directly underneath the device. [The RSO] suspects that the shutter vibrated off. The shutter is usually in the open position as the hopper is operational 24/7 measuring coal as it moves through the hopper. There were no employees in the hopper and the device sits 10-12 feet above the ground. After [IDPH spoke] with [the RSO] and considering their license conditions, [the RSO] is calling the service provider to come to their location and assess the repositioning of the shutter.
