Transnuclear has won a key regulatory approval for its new waste cask that will allow larger shipments and can accommodate fuel from Areva's EPR plant design.

Operational in vertical and horizontal configurations, the containers can accommodate used research reactor fuel, experimental nuclear plant fuel, irradiated equipment and spent fuel bundles from commercial reactors, including the 14-foot-long assemblies of the EPR.

 “Transnuclear’s forward-looking Long Cask offers the highest capacity NRC-licensed cask for the transport of used fuel compared to what is on the market today," Transnuclear CEO Michael McMahon said in a release.

Transnuclear, an Areva subsidiary based in Columbia, Md., began the NRC licensing process for the new cask in 2011 and continues to work with the Department of Transportation.
