| Title | Agreement State Report - Stuck Radiography Source |
| Event Description | The following information was received via E-mail:
Licensee reported a stuck radiography source that occurred at approximately 2315 CDT on May 6, 2013. Licensee's RSO [Radiation Safety Officer] responded to incident site, increased barricades, maintained perimeter, and notified Chevron RSO. Licensee's source was fully retracted into the shielded position at 0100 CDT [on May 7, 2013]. The Licensee's RSO received 20 mR conducting the source retrieval. The incident occurred while performing work at the Chevron Pascagoula Refinery. Mississippi Report Number: MS-13002
The following report was received via e-mail: On 5/6/2013, the Licensee had a two man crew performing industrial radiography at the Chevron Plant. The radiographer was unable to crank the source back into the camera after his third exposure. The source was then cranked back into the collimator. The radiographer repositioned the cranks and tried to retract the source again without success. The radiographer and assistant radiographer extended the restricted area boundary and called the Licensee's night safety officer on site. The Licensee's RSO then notified Mistras Group's CRSO [Corporate Radiation Safety Officer] and plant personnel of the incident. The Licensee's RSO, once on site, discovered from conversation with the radiographer that the drive cable was hitting a melted area of the conduit and not letting the drive cable pass through. The melting of the (black) return conduit of the cranks occurred because it was placed over a non-insulated pipe from the plant's furnace. The Licensee's RSO made the decision to cut the conduit at the melted area of the cranks to save time and reduce exposure while trying to retract the source. This provided clearance for the drive cable to pass through and allowed the source to retract back into the fully shielded position inside the camera. The camera, guide tube, and cranks were surveyed by the RSO upon source retraction. The State (Mississippi) has closed this case. Notified the R4DO (Walker) and FSME Events Resources via email. |
