RITM-200
The RITM-200 is an integrated generation 3+ pressurized water reactor developed by OKBM Afrikantov and designed to produce 55 MWe. The design is an improvement of KLT-40 reactor. It uses up to 20% enriched uranium-235 and can be refueled every 10 years for a 60 year planned lifespan in floating power plant installation. If installed in a stationary power plant the fuel cycle is 6 years. The RITM-200 has a compact integrated layout placing equipment within the steam generator casing, halving system weight compared to earlier designs and improving ability to operate in rolling and pitching seas. It powers the Project 22220 icebreakers, the first of which went critical in October 2019. In November 2020 Rosatom announced plans to place a land-based RITM-200N SMR in isolated Ust-Kuyga town in Yakutia. The reactor will replace current coal and oil based electricity and heat generation at half the price. Technical design for this type of RITM-200 core should be finished in 2022. Ref ...

Akademik Lomonosov
''Akademik Lomonosov'' (russian: Академик Ломоносов) is a non-self-propelled power barge that operates as the first Russian floating nuclear power station. The ship was named after Russian Academy of Sciences, academician Mikhail Lomonosov. It is docked in the Pevek harbour, providing heat to the town and supplying electricity to the regional Chaun-Bilibino power system. It is the world’s northernmost nuclear power plant. History Construction started at the Sevmash Submarine-Building Plant in Severodvinsk. The keel of ''Akademik Lomonosov'' was laid on 15 April 2007 and completion was initially planned in May 2010. The celebrations were attended by the first deputy prime minister of Russia, Sergei Ivanov, and by the head of Rosatom, Sergei Kiriyenko. In August 2008, the Russian government approved the transfer of work from Sevmash to the Baltic Shipyard (Baltiysky Zavod) in Saint Petersburg. A second keel-laying was done at the new shipyard in May 2009. ''Akad ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

The OK-650 reactor is the nuclear fission reactor used for powering the Soviet Navy's Project 685 Плавник/''Plavnik'' (Mike), Project 971 Щука-Б/''Shchuka-B'' ( Akula), and Project 945 Барракуда/''Barrakuda'', Кондор/''Kondor'', and Марс/''Mars'' ( Sierra) submarines, and in pairs to power the Project 941 Акула/''Akula'' (Typhoon) and Project 949 Гранит/''Granit'' and Антей/''Antei'' ( Oscar) third generation submarines. This pressurized water reactor (PWR) uses 20-45% enriched uranium-235 fuel to produce 190 MW of thermal power. Developed during the 1970s, these reactors were designed with the aim of minimizing accidents and malfunctions. Monitoring subsystems, designed for rapid detection of leaks, were included, along with newer-generation emergency cooling systems for the main reactor core. The reactor is now also used to power the new Project 955 Borei submarines. It was developed by OKBM Afrikantov OKBM Afrikantov ...

Fast Breeder Reactor
A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use, by irradiation of a fertile material, such as uranium-238 or thorium-232, that is loaded into the reactor along with fissile fuel. Breeders were at first found attractive because they made more complete use of uranium fuel than light water reactors, but interest declined after the 1960s as more uranium reserves were found,Helmreich, J.E. ''Gathering Rare Ores: The Diplomacy of Uranium Acquisition, 1943–1954'', Princeton UP, 1986: ch. 10 and new methods of uranium enrichment reduced fuel costs. Fuel efficiency and types of nuclear waste Breeder reactors could, in principle, extract almost all of the energy contained in uranium or thorium, decreasing fuel requirements by a factor of 100 compared to widely used once-through light water reactors, which extract less tha ...
