| Title | Agreement State Report - Failure of Source to Retract to Safe Position |
| Event Description | The following report was received from the Illinois Emergency Management Agency via email:
On Thursday, November 3, [2016] the licensee's Corporate RSO [Radiation Safety Officer] called to advised that one of their crews experienced a source retraction problem while at a temporary jobsite. Radiography shots were being taken with a nominal 60 Ci Ir-192 source at the Wood River Refinery, Wood River, IL. During a shot around 1230 [EDT] that afternoon it became obvious that the source would not retract using normal means. The crew contacted the local facility radiation safety officer to advise him of the event. The local radiation safety officer responded to the site within 30 minutes to discover that a portion of the drive cable assembly had been laid across a bare spot on a pipe that was otherwise insulated. The heat from the uninsulated section of pipe had caused the return side, cable housing coating to melt, forming an obstruction that the return cable could not pass. The RSO, having retrieved a source from a similar predicament in the past was able to quickly and efficiently cut the return side cable guide tube creating an open path for the cable and bypass the obstruction. The source was then able to be returned to the safe position without undue effort. The matter was resolved within an hour. The drive cable equipment has been removed from service. The camera was inspected and tested and put back into service. The direct ion storage dosimeter for the facility RSO was immediately analyzed at the end of the event and a dose of 3 mR was noted. Doses for the crew members were similarly analyzed and both found to be less than 30 mR since the last read which was performed at the end of the previous month. As the area being radiographed was on an overhead scaffold, no other personnel were in the work area at any time during the event other than the radiographers who maintained vigilance over the scene. A preliminary report with supporting photos was received the next day. Based on that report, an immediate investigation was not conducted at that time.
