| ENS 53367 | 26 April 2018 17:30:00 | 10 CFR 30.50(b)(2) | Unable to Retract Source Due to Guide Tube Damage | The following report was excerpted using information provided via email: On Thursday, April 26, 2018, a crew was performing radiographic operations. At approximately 12:30 p.m. (CST), the crew experienced an incident wherein a 2-inch diameter, 8-foot long pipe rolled off a 2-1/2-foot tall table, resulting in the guide tube being used by the crew to be smashed (under the) pipe. The dent in the guide tube prevented the source from being returned to the fully shielded position. Exact Location of Event: Pennsboro, WV Licensed Material Involved: SPEC-150 Exposure Device (s/n 2056) SPEC G-60 Source (s/n ZA0905) lr-192 45 curies Corrective Action Taken/Planned: To immediately correct the problem and retrieve the source, allowing it to be returned to the fully shielded position, the black sheathing on the outside of the guide tube was removed in the damaged area. Using a hammer, the damaged area was rounded out enough to allow the source to be returned to the fully shielded position. The guide tube involved in this incident has been removed from service and will be destroyed as to prevent it from being reused. Retraining on these types of situations will be provided to all employees, and this incident specifically, will be discussed during this quarter's safety meetings within all company locations. To prevent a reoccurrence of an incident of this type, we have made plans with the company for whom we were providing radiography for to stage and brace piping moving forward. Extent of Exposure: The personnel responsible for performing source retrieval recorded a total dose of 60 mR during the retrieval. As soon as this event occurred, the crew performing radiographic operations immediately reassessed and set up appropriate 2 mR/hr boundaries, notified their Site RSO (Radiation Safety Officer) and Branch Manager, and maintained constant visual surveillance until source retrieval personnel arrived at the jobsite. At no time were any unmonitored employees in any immediate danger of being overexposed, nor were any of our company personnel, all of whom were utilizing proper radiation detection equipment. |
