Casks for the transport and storage of spent nuclear fuel
One of the key activities of ŠKODA JS is the production of fuel handling equipment.
Casks are used for the transport and dry storage of spent nuclear fuel. At ŠKODA JS, we produce containers of our own design, and we also produced containers in cooperation with the company GNS mbH Essen. ŠKODA JS produced the first cask in 1993.
Casks of GNS design and the licensed production of casks
Over the years, we have manufactured several types of casks based on the design by the German company GNS for various locations – the CASTOR®1000/19 cask with a body made of ductile cast iron for a Czech nuclear power plant, the CONSTOR® made of metal-concrete for a nuclear power plant in Lithuania, the CASTOR®HAW 20/28 CG cask for the storage of highly active waste for German and Swiss nuclear power plant operators, and the CONSTOR®440/84 cask made of reinforced concrete, including a fuel basket of ŠKODA JS’s own design, for a nuclear power plant in Bulgaria.
Under the license from the GNS Company, CASTOR®440/84 M casks with a body of ductile cast iron, including a fuel basket of ŠKODA JS’s own design, were produced for a nuclear power plant in the Czech Republic.
Casks of our own design
Since 1998, we have also been producing and supplying casks of our own design. We have focused primarily on special-purpose casks, e.g., for fuels from research reactors, for the transport of radiation emitters, witness samples and medical emitters. Over the past 20 years, we have designed a total of 15 such casks for Czech and Slovak nuclear units as well as for Czech, German and Swiss companies and research reactors. One of the most recent projects was the design, production and delivery of a cask wagon for the Chernobyl NPP, which serves for the transport of 9 spent fuel assemblies from the RBMK reactor.
At the end of 2018, we supplied the first ŠKODA 1000/19 spent nuclear fuel cask of our own design to the Temelín NPP. This cask was developed and produced entirely by ŠKODA JS. It is designed for the transport and long-term storage of VVER 1000 spent nuclear fuel. The fuel basket will hold 19 fuel assemblies. The cask weighs 119 tons and its height is over 5 meters. We are to supply 58 of these casks to the Temelín NPP by 2035.
In 2021, we supplied the first casks of our design ŠKODA 440/84 for Dukovany NPP. This cask was completely developed and manufactured by ŠKODA JS. It is designed for the transport and long-term storage of spent VVER 440 nuclear fuel. The inner basket has a capacity of 84 fuel assemblies. A total of 91 pieces will be delivered to the Dukovany NPP by 2048.
