Rosatom readies Chukotka mini nuclear plant for 2030 launch
Rosatom has moved its Shelf-M mini nuclear plant in Chukotka into engineering surveys, targeting construction in 2027 and launch in 2030.

Rosatom has completed the economic case for its first land-based mini nuclear power plant built around the Shelf-M reactor and has moved the project into the engineering survey stage. The plant is planned for the Sovinoe gold deposit in Chukotka’s Chaunsky District, where large-scale power generation is considered too expensive to make sense.
The standout feature is its passive residual heat removal system. If external power is lost, the reactor is designed to remove heat on its own, without diesel generators or operator intervention, and shift into a safe state. Rosatom is effectively adapting technology refined over years on nuclear icebreakers for use on land.
For isolated industrial sites, the pitch is straightforward. Alexey Likhachev has linked reactors like this to areas where extending main transmission networks or building a large nuclear plant is impractical. For mining companies, power is one of the heaviest cost items; for the state, the project offers a way to tie energy supply to Arctic and Far East resource development.

Shelf-M reactor specifications
Rosatom says the reactor will be delivered as a monoblock measuring 11 meters long and weighing 370 tons, avoiding lengthy on-site assembly from multiple large components. Its stated output is 10 MW of electric power and 35 MW of thermal power.
Other key figures include:
- 60-year service life
- Fuel reload every eight years
- Passive cooling designed to operate at about 30% of nominal power
The fuel is uranium dioxide in a silumin matrix, the same approach used on icebreakers. Rosatom presents that as a proven Arctic design rather than an experimental one.
Construction timeline for the Chukotka plant
According to the company, construction is set to begin in 2027. Physical launch is scheduled for 2030, with commercial operation planned for 2032.
If that timeline holds, Shelf-M would become one of Russia’s most concrete answers to the global push around SMRs, or small modular reactors. Projects in the US, Canada, and Europe are also targeting remote mines, data centers, and northern towns, but many still have to show that small-scale nuclear economics can survive real construction and approval processes.
The Chukotka project has one advantage: it already has a real end user, rather than being framed around broad energy-transition rhetoric. For Rosatom, it is also a test of whether the engineering behind its icebreaker fleet can win over mining companies, industrial clusters, and regions outside the unified power grid.
