OKBM Afrikantov (full name: OAO I. I. Afrikantov OKB Mechanical Engineering, Russian: Опытное конструкторское бюро машиностроения им. И. И. Африкантова) is a nuclear engineering company located in Nizhny Novgorod, Russia. It is a subsidiary of Rosatom. The company is named after Igor Afrikantov.

The company is best known as the main designer for the Soviet Union's and Russia's flagship nuclear propulsion projects, including reactors for nuclear submarines, nuclear-powered icebreakers, and the floating nuclear power plant project. It also designs fast breeder reactors.


The company was founded in 1945. In 1998, it was named after its former chief designer and director I. I. Afrikantov.


The company is a developer of the nuclear reactors. It has designed and assembled KLT-40S reactors for the first Russian floating nuclear power station Akademik Lomonosov.[1] It also developed the RITM-200 design pressurized water reactor which is used for LK-60 model nuclear-powered icebreaker.[2]

OKBM Afrikantov participated in the construction of China Experimental Fast Reactor.[3]

Naval reactors[edit]

The company has been the primary designer of naval reactors for both military and civilian uses: KN-3 reactor, OK-150 reactor, OK-550 reactor, OK-650 reactor, KLT-40 reactor, RITM-200, ABV Reactor, VBER-300 and more.
