The US-based Cooperative Threat Reduction Program sponsored construction of six special TK-VG-18-2 type rail cars, Nuclear.ru reported. The rail cars for spent nuclear fuel passed all the required tests and were certified for operation. Each car can take two 40-tonn containers with spent nuclear fuel. The new train will allow to speed-up the spent nuclear fuel shipment to the storage and reprocessing points. Until recent time Russia had two nuclear trains with four cars each. The Norwegian Government sponsored the second trains construction.
