Russian floating nuclear power station
Encyclopedia
Floating nuclear power stations (Russian
: плавучая атомная теплоэлектростанция малой мощности, АТЭС ММ - lit. floating combined heat and power
low-power nuclear station) are vessels projected by Rosatom that present self-contained, low-capacity, floating nuclear power plant
s. The stations are to be mass-built at shipbuilding
facilities and then towed to the destination point in coastal waters near a city, a town or an industrial enterprise. Although the world's first floating nuclear power station was MH-1A
, the Rosatom project represents the first mass production of that kind of vessel. By 2015, at least seven of the vessels are supposed to be built.

as the place for building the first floating power generating station. Sevmash
was appointed as general contractor. Construction of the first floating nuclear power station, Akademik Lomonosov
, started on 15 April 2007 at the Sevmash Submarine-Building Plant in Severodvinsk. However, in August 2008 construction works were transferred to the Baltic Shipyard
in Saint Petersburg
, which is responsible also for construction of the next vessels. Akademik Lomonosov was launched on 1 July 2010.
Each vessel has two modified KLT-40 naval propulsion reactors
together providing up to 70 MW of electricity or 300 MW of heat, enough for a city with a population of 200,000 people. It could also be modified as a desalination
plant producing 240,000 cubic meters of fresh water a day. Another modification will be supplied by two ABV-6M reactors with a capacity of around 18 MWe (megawatts of electricity). Also, 325 MWe VBER-300
and 55 MWe RITM-200 reactors have been mentioned as potential reactors to use for the floating nuclear power station.

s that are also used for scientific and Arctic tourism expeditions. The Russians have commented that a nuclear reactor that sinks, such as the similar reactor involved in the Kursk
explosion, can be raised and probably put back into operation. At this time, it is not known what, if any, containment structure
or associated missile shield will be built on the ship. The manufacturers believe that an airliner striking the ship would not destroy the reactor. According to MosNews, a Russian news outlet, there is no way an airliner striking the ship would destroy the reactor.
The 2011 Japanese nuclear accidents
due to the 2011 Tōhoku earthquake and tsunami
provide a sharp contrast to some comparative safety advantages of floating nuclear plants. Land based nuclear facilities must be designed for severe ground accelerations due to earthquakes. Many are placed close to a seacoast for access to sea water for cooling. Coastal locations tend to be the areas of maximum tsunami damage, requiring protective design and risk of catastrophic failure. A floating facility, near a coast but not in shallow water, can avoid the worst problems of earthquakes and tsunamis. In deep enough water, tsunamis have minimal effect on floating structures, and earthquakes transmit much less force to them. In the event of an accident, terrorist attack, or other calamity, it is essential to keep the core cooled, usually by covering it with water. An emergency measure can be to lower the core into the sea. In the worst case, accidental sinking or intentional scuttling will keep sea water on the core and prevent atmospheric release - again, especially in deep enough water. Finally, retired land based nuclear power plants can be difficult and expensive to clean up, including safety hazards of contamination. A floating plant is towed to a remote location that handles multiple such tasks.
A 2004 book on Russian floating nuclear power stations was written by a number of authors, including "Vladimir Kuznetsov, formerly of the Russian Federal Inspectorate for Nuclear and Radiation Safety; Alexey Yablokov, a biologist, former environmental advisor to the Russian president and president of the Center for Russian Environmental Policy; Yevgeney Simonov, senior engineer at the Obninsk nuclear power plant; Vladimir Desyatov, an engineer who worked in nuclear submarine construction; and Alexander Nitikin." The book concludes that such stations are impossible to protect against terrorism, that safety cannot be guaranteed ("The only question is how serious the emergency and its consequences."), and that an accident would be uniquely difficult to contain. Besides that, the book argues that such stations would be uneconomic.
. Five of these will be used by Gazprom
for offshore oil and gas field development and for operations on the Kola
and Yamal
peninsulas. Other locations include Dudinka
on the Taymyr Peninsula
, Vilyuchinsk
on the Kamchatka Peninsula
and Pevek
on the Chukchi Peninsula
. In 2007, Rosatom signed an agreement with the Sakha Republic to build a floating plant for its northern parts, using smaller ABV reactors.
According to Rosatom, 15 countries, including China, Indonesia, Malaysia, Algeria, Namibia, Cape Verde and Argentina, have shown interest in hiring such a device.

Fueling
The floating power stations need to be refueled every three years while saving up to 200,000 metric tons of coal and 100,000 tons of fuel oil a year. The reactors are supposed to have a lifespan of 40 years. Every 12 years, the whole plant will be towed home and overhauled at the wharf where it was constructed. The disposal of the nuclear waste will be organized by the manufacturer and supported by the infrastructure of the Russian nuclear industry. Thus, virtually no radiation traces are expected at the place where the power station produced its energy.Safety
Environmental groups are concerned that floating plants will be more vulnerable to accidents and terrorism than land-based stations. They point to a history of naval and nuclear accidents in Russia and the former Soviet Union, including the Chernobyl disasterChernobyl disaster
