The containers were ordered by the Murmansk Shipping Company, Sevmash press chief Mikhail Starozhilov said, adding “the testing of the container is already complete.”

The TUK-20 containers are made for storage of SNF, which can not be converted by available reprocessing technologies. The Lotta nuclear service ship, docked outside Murmansk, contains a large amount of the dangerous spent fuel.

Reloading the waste from the Lotta will require 50 of the special metallic-ore-concrete TUK-120 containers, the Barents Observer said.

Experts say the containers can solve the problem of storage of the “unreclaimable” nuclear fuel for the next 50 years.
