The crew was using a SPEC 150 exposure device containing a 92 curie iridium - 192 source. The crew was working inside a shooting bay at a customer's location when the event occurred. The radiographers had completed an exposure and attempted to retract the source. The RSO stated the radiographers could not get the lock on the camera to trip. As they approached the camera they noted the dose rate reading on their dose rate meter was pegged so they retreated to the area where they operated the crank out device and called the RSO. The RSO, who is authorized by their license to recover sources, drove to the location and performed the source recovery. The RSO placed shielding over the source which was located in the collimator and removed the guide tube from the camera. The RSO found the drive cable sticking through the front of the camera. He disconnected the crank out device from the rear of the camera and found the drive cable had gone completely through the camera. The RSO found that the drive cable had broken inside the drive cable protective housing about 18 feet from the source. The RSO manually retracted the source into the camera by pulling on the drive cable. The source was returned to its fully shielded position. The licensee will send drive cable assembly to the manufacturer for inspection. No over exposure or exposure to a member of the general public occurred as a result of this event. Additional information on this event will be provided in accordance with SA-300."

Door-61 is a credited High Energy Line Break (HELB) / Fire / Flood Barrier in addition to its function to maintain the Control Room envelope. The door stop was subsequently unbolted from the floor and the door was free to close. Door-61, South Control Room Door, has since been inspected, and at 1750 [CDT], was declared functional as a HELB / Fire / Flood Barrier and Operational for purposes of maintaining the Control Room Envelope. During the 26 minutes the door was stuck open, the Control Room was in an unanalyzed condition with regards to protection from a High Energy Line Break." The licensee notified the NRC Resident Inspector. | |
