The RITM-200 is an integrated Generation III+ 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. [1] 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. [2]

It powers the Project 22220 icebreakers, the first of which went critical in October 2019. [3] Since 2012, ten RITM‑200 reactors have been manufactured for five Russian Project 22220 multi-­purpose nuclear icebreakers. Six reactors are installed on the Arktika, Sibir and Ural icebreakers, which are already in operation. Construction of the other two, Yakutia and Chukotka, is nearing completion. [4]

In November 2020 Rosatom announced plans to place a land-based RITM-200N [5] SMR in isolated Ust-Kuyga town in Yakutia. [6] The reactor will replace current coal and oil based electricity and heat generation at half the price. [7] In April 2023, a license was given for a pilot RITM-200N plant to be built near the village of Ust-Kuiga, with commissioning planned for 2028. [8]

RITM‑200M reactors will also be installed on the floating power units to supply power to the Baimsky GOK mining site in Chukotka. [4] They are planned to be put in operation in 2029. [9]

The volume of investments in the project was estimated at RUB900bn ($10bn). However, Georgy Fotin, Director General of Baimskaya Management Company, said in April, that the assessment had been revised upwards and some RUB170bn had already been invested.

The Baim project will be supplied with electricity using the new FNPPs of the PEB-106 project, designed for operation in the Far North and Far East. They will use the new RITM-200S reactors, which will supply 106 MWe to consumers. Their service life is 40 years and the interval between refuelling is five years. The units will be held in place by rigid mooring devices, which make it possible to compensate for the movement of the power units from the ebb and flow. The power generated by the power unit is transmitted to the shore using 50 high-voltage cables. Three main floating power units and one reserve unit will be installed, which will be used during the repair of the main units. [10]

In June 2024 Rosatom signed a contract to build a Russian-­designed small modular reactor nuclear power plant (SNPP) in Uzbekistan. The project provides for the construction of a 330 MW nuclear power plant in the Jizzakh Region of Uzbekistan. The plant will operate six 55 MW small modular reactors. [4]

RITM-400

November 2023 — Nornickel and the State Atomic Energy Corporation Rosatom will consider the possibility of setting up low-capacity nuclear power plants to supply energy to the Norilsk Industrial District. A high-tech project of a low-capacity nuclear power plant based on the latest RITM-400 reactor unit may be considered as a priority.

RITM-400 is a project of a pressurised water reactor with a planned capacity of 80 to 90 MW. The reactor is being developed by OKBM Afrikantov, a nuclear engineering company that is part of Rosatom [11]

<span class="mw-page-title-main">Nuclear-powered icebreaker</span> Type of ship

A nuclear-powered icebreaker is an icebreaker with an onboard nuclear power plant that produces power for the vessel's propulsion system. Although more expensive to operate, nuclear-powered icebreakers provide a number of advantages over their diesel-powered counterparts, especially along the Northern Sea Route where heavy power demand associated with icebreaking, limited refueling infrastructure along the Siberian coast, and endurance required make diesel-powered icebreaker operations challenging. As of 2023, Russia is the only country that builds and operates nuclear-powered icebreakers, having built a number of such vessels to aid shipping along the Northern Sea Route and Russian arctic outposts since the Soviet era.

<span class="mw-page-title-main">Small modular reactor</span> Small nuclear reactors that could be manufactured in a factory and transported on site

Small modular reactors (SMRs) are a class of small nuclear fission reactors, designed to be built in a factory, shipped to operational sites for installation and then used to power buildings or other commercial operations. The first commercial SMR was invented by a team of nuclear scientists at Oregon State University (OSU) in 2007. Working with OSU's prototype, NuScale Power developed the first working model, available to the US market, in 2022. The term SMR refers to the size, capacity and modular construction. Reactor type and the nuclear processes may vary. Of the many SMR designs, the pressurized water reactor (PWR) is the most common. However, recently proposed SMR designs include: generation IV, thermal-neutron reactors, fast-neutron reactors, molten salt, and gas-cooled reactor models.
