Rosatom organisations transport nuclear materials by air, and sea, as well as in special road and rail containers. Transport storage containers (TSCs) are used for this purpose, which are produced by enterprises operating under the state corporation. These highly pressurised metal containers have been certified to carry nuclear materials. They are able to withstand the pressure of a naked flame and a fall from a height of 16 m for an extended period of time. The different types of transport storage containers are designed to transport both fresh, and spent nuclear fuel. Apart from that the material is stored for a long period of time in these containers.
