Empty nuclear fuel cylinders to be returned to Russia have been piling up at US fuel fabrication facilities since Canada imposed a new set of sanctions on Russian transport last August. This in turn has created a shortage of these cylinders in Russia. While a solution is in sight, this problem has complicated nuclear fuel transport in a climate already adverse to the shipment of Class 7 radioactive materials, and a shortage of transport cylinders is already slowing further exports of Russian EUP, including a large shipment to China.
