Beginning in 2016, NAC cooperated with U.S. Department of Energy’s National Nuclear Security Administration (NNSA) and Atomic Energy of Canada, Ltd (AECL) to transport 115 shipments of highly enriched uranium (HEU) liquid from the Chalk River Laboratories in Ontario, Canada to the Savannah River Site in Aiken, South Carolina.

The liquids were a byproduct of a process that separated out Molybdenum-99 (Mo-99), which is used for medical procedures in the U.S. and Canada. NAC designed, managed fabrication, and obtained licensing from the U.S. Nuclear Regulatory Commission for a special canister to safely contain and transport the HEU liquids in the NAC LWT Type B cask (USA/9225/B(U)F-96). NAC was also responsible for:

·        Engineering, licensing and fabrication of the HEUNL containers

·        Design, analysis and fabrication of the horizontal container loading and transfer system

·        Cask loading operations, technical support and transport logistics

More information on the four-year project is available in these NNSA articles:
