| Title | Shipment Exceeds Surface Contamination Limits |
| Event Description | The following information was provided by the licensee via phone and email:
On November 21, 2025, at 0835 CST, River Bend Station (RBS) was operating at 78 percent reactor power when the [radioactive waste] shipping department received a cask from the Waste Control Specialists disposal facility in Andrews County, TX via [a common carrier]. A smear sample was collected and exhibited surface contamination above the Department of Transportation (DOT) limits, specified in 49 CFR 173. The carrier was notified at 1713 CST. The surface contamination exceeded 24,000 [disintegrations per minute per centimeter squared] for beta gamma [activity]. Supervision was immediately contacted and placed the shipment into a radiological controlled area. An investigation was performed to the extent of the condition of the loose surface contamination of the cask to determine if it was isolated to the immediately accessible areas of the cask due to an installed rain cover. The investigation concluded that the condition was extended to the surface of the cask where the average surface area exceeded DOT limits. This condition is immediately reportable to the NRC headquarters operations center per 10 CFR 20.1906(d)(1). |
