Russia has been pursuing floating nuclear power stations to provide electricity and heat to isolated settlements, such as those on the Arctic coast. The first power ship, Akademik Lomonosov, was launched in 2010, and began operation in December 2019, being fully commissioned in May 2020. The ship, which has no propulsion of its own, was towed into position by an icebreaker. Power is generated by two KLT-40S reactors, which are based upon the reactors developed for nuclear powered icebreakers. Together, the reactors provide 300 megawatts of thermal power, generating 70 megawatts of electrical power. Running in co-generation mode, the reactors can deliver 170 megawatts of thermal power and 30 megawatts of electric power. As a by-product, the reactors produce 240,000 litres per day of fresh water from desalination of seawater. The reactors use low-enriched (14.1%) uranium, with an interval of 3 years between refuellings.
Presumably, Russia is not as concerned with security of reactors located entirely within its territory in difficult-to-access regions.
