Two new types of metal/concrete container for long-term storage and transportation of spent fuel have successfully passed tests successfully. TUK-104 containers, built by the Izhorskiye Zavody company in St Petersburg, are intended to hold 57 assemblies previously stored for up to five years. They will be used to store spent fuel from RMBK and submarine reactors, and are over three times cheaper than the German-made ones used at Ignalina.

Prototypes of TUK-109 containers, made by the Energoteks plant in Kurchatov in the Kursk region, can hold 72 assemblies.
