Mongolia is examining a proposal from the Russian state corporation Rosatom to construct a small nuclear power station, the Russian ambassador to Ulaanbaatar, Alexey Yevsikov, told Izvestia on 3 January. According to the diplomat, Mongolian authorities have been actively studying the project since August 2024, assessing a design based on Rosatom’s compact reactor technology.
Mongolia small nuclear plant plans and next steps
Ambassador Yevsikov said the proposed facility is intended for a region where a significant increase in electricity consumers is expected. Rosatom has promoted a modular approach to nuclear generation in several countries, arguing that smaller units can be delivered faster and sited closer to demand centres than traditional large stations. In September 2024, Rosatom sources reported that technical design work for what would be Mongolia’s first nuclear power station was nearing final approval.
The report indicates that Mongolian ministries and technical teams are conducting feasibility assessments covering grid integration, water supply, and local infrastructure. Officials will also need to resolve regulatory matters, licensing and environmental reviews before construction can begin. International experience shows these processes typically require multiple years of planning and consultation.
Benefits and considerations for Mongolia
Proponents of the plan point to potential advantages for Mongolia’s energy security and economic development. A small nuclear station could provide steady baseload power to support industrial projects, mining operations and urban growth in areas with rising demand. The modular nature of the proposed technology may allow phased deployment and relatively lower upfront capital compared with larger reactors.
However, experts caution that financing, public engagement and regulatory capacity will be decisive. Mongolia would need to secure funding arrangements, possibly involving state-backed loans, export credit or partner investment. Local communities and civil society groups may seek detailed information about safety, waste management and the station’s environmental impact. Technical assistance and training for Mongolian personnel will be essential for long-term operation.
Regional context and international cooperation
The announcement adds to a series of Rosatom initiatives to offer small-scale reactors to partner countries. In recent years the company has negotiated projects across Africa and Asia. Moscow frames such agreements as part of wider industrial and technological cooperation with partner states.
For Mongolia, which shares close economic ties with both Russia and China and seeks to diversify its energy mix, the Rosatom proposal represents a strategic choice. The government must balance immediate energy needs against long-term commitments to safety, financing and regional diplomacy.
Officials did not publish a detailed timetable. Observers expect the coming months to focus on completing technical reviews, carrying out environmental impact assessments and opening discussions on funding and regulatory arrangements. If approvals proceed without major obstacles, preparatory works could begin within a few years, subject to political and financial agreement.
The proposed project is one of several international nuclear initiatives that underscore growing interest in small modular reactor technology as countries evaluate options for reliable low-carbon power. For Mongolia, the decision will reflect economic priorities, public sentiment and the capacity to implement a safe, regulated nuclear programme in partnership with Rosatom.
Key Takeaways:
- Mongolia is studying a proposal from Russia’s Rosatom to build a small nuclear power station to meet growing regional demand.
- Technical design was reported to be nearing final approval in September 2024, with Mongolian review active since August 2024.
- Officials say the plant would serve areas expecting a rise in electricity consumers and use Rosatom’s innovative small reactor technology.
- Next steps include regulatory approvals, financing discussions and site selection ahead of construction.
