OKBM Afrikantov has been developing power installations for the icebreaker fleet for more than 60 years. The first generation of reactor installations is represented by the OK-150 loop-type installation for the icebreaker Lenin. At the exhaustion of its operating life it was replaced by the second-generation OK-900 installation. The next stage of the origination of reactor installations for civilian ships became the development of KLT-40 and KLT-40M. Currently, owing to the growth of cargo traffic along the Northern Sea Route, the nuclear icebreaker fleet must be enlarged. Both operating and new general-purpose nuclear icebreakers are planned for pilotage of freighters. The new reactor installation RITM-22 with improved metrics was developed for general-purpose icebreakers. The reactor installation RITM-400 was developed for Lidertype icebreakers and can be used in the future in other vessels as well as small nuclear power installations.
