More Information
Summary:A system for encapsulating and storing disused radiological sources in sealed capsules is provided, the system having a basket to removably position capsules relative to each other, the capsules containing the radiological sources; a containment vessel for receiving the basket; and a cask reversibly encapsulating or otherwise housing the containment vessel. Also provided is a method for packaging, transporting and storing disused radiological sources, the method having the steps of transporting sealed capsules containing radiological sources from water pools to baskets; placing the basket in a containment vessel and sealing the vessel with helium backfill; placing the vessel in a cask and reversibly capping the cask; surrounding the cask with personnel a shield and crumple zones to create a construct; and transporting and storing the construct until its final disposal at a geological repository or a deep borehole, all without repackaging of the disused radiological sealed capsules.
