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.

OKBM Afrikantov为破冰船队开发动力装置已有60多年的历史了。第一代反应堆设备以破冰船列宁的OK-150回路式设备为代表。在其使用寿命耗尽时，它已被第二代OK-900安装所取代。民用反应堆装置的下一个发展阶段是KLT-40和KLT-40M的开发。当前，由于北海路线沿线货运量的增长，必须扩大核破冰船队。计划将营运中的和新型的通用核破冰船用于货机的领航。具有改进指标的新反应堆装置RITM-22是为通用破冰船开发的。
