New Reactor for Nuclear-Powered Ice-Breakers

A first batch of unique fuel for the reactor at the Arktika nuclear-powered ice-breaker which is under construction at the Baltiyskiy Zavod (Baltic Shipyard) was produced by the Machine-Building Plant Public Joint-Stock Company (PJSC MSZ). A new RITM-200 nuclear power unit was developed for the ice-breaker. In comparison with other power units, the new design has more compact dimensions, higher level of robustness and increased safety. According to the Bochvar High-Technology Scientific and Research Institute for Inorganic Materials (AO VNIINM) where this unit was designed, one charge of the new nuclear fuel shall be enough for 7 years of operation, and the effective lifetime shall be 40 years.

The High-Technology Scientific and Research Institute for Inorganic Materials named after Bochvar High-Technology Scientific and Research Institute for Inorganic Materials (AO VNIINM) proposed technologies, materials and designs of heat-producing elements, burnable absorbers and starting neutron sources for the nuclear-powered ice-breaker’s active zone.

According to Aleksandr Vatulin, Senior Expert at AO VNIINM, the team has developed a truly unique heat-producing element. Owing to innovative technologies its ensures effective operation of the power unit. The capacity of the ice-breaker reactor is two times higher than that of the available active zone output at the previous generation nuclear ships.
