Key Takeaways:
- Rosatom has delivered a comprehensive proposal to Armenia to construct a new nuclear reactor, with the Russian state corporation ready to begin work promptly.
- The decision rests with Yerevan as Armenia explores options including small modular reactors and bids with the US, China, South Korea and France.
- Rosatom emphasises proven VVER technology and favourable financial terms; Armenia currently operates a single VVER-440 unit fuelled by TVEL.
- Any project would affect Armenia’s energy security and regional ties, including ongoing cooperation with Russia to extend the existing plant’s life to 2036.
Moscow-based state nuclear corporation Rosatom has handed Armenian authorities a package of detailed proposals to build a new reactor block at the Metsamor nuclear power plant, the Russian ambassador to Armenia, Sergey Kopyrkin, said in an interview with the Armenian newspaper Noev Kovcheg.

According to Kopyrkin, Rosatom’s package offers technology that is already tried and tested and comes with financially attractive terms. “The ball is in Yerevan’s court,” he said, adding that the corporation could begin implementation of the project within a short timeframe if Armenia opts to proceed.
The announcement comes as Yerevan weighs several pathways to secure its energy future. In October Prime Minister Nikol Pashinyan said the country had decided to pursue a small modular reactor and was discussing new reactor projects with a range of international partners, including the United States, Russia, China, South Korea and France. Officials in Moscow and Yerevan have also held talks about extending the operating life of Armenia’s existing plant to 2036.
Metsamor is a crucial power source for Armenia. The plant currently operates a single VVER-440 reactor of the first generation, with fuel supplied by TVEL, a Rosatom subsidiary. Rosatom stresses that real alternatives offering the same level of proven technology and favourable financing are not apparent, according to Kopyrkin.
Energy ministers and technical teams are likely to scrutinise Rosatom’s proposal in the coming months. Key considerations for Armenian authorities will include safety upgrades, financing and construction timelines, regulatory approval and how any new block would integrate with grid needs and climate commitments.
Russia and Armenia have longstanding cooperation in the nuclear sector, and Moscow has reiterated its readiness to support both the refurbishment and potential expansion of Metsamor. In late September President Vladimir Putin discussed the plant with Prime Minister Pashinyan, noting that Rosatom is working on extending the existing station’s service life.
For Armenia, the choice between a small modular reactor and a more conventional new block involves trade-offs. Small modular reactors can offer lower upfront capital requirements and shorter construction schedules, while a conventional VVER block would draw on a long track record of operational experience and established supply chains. Rosatom’s proposal appears aimed at highlighting those operational and financial advantages.
Any decision will carry geopolitical and economic implications. Selecting Russian technology would deepen energy ties with Moscow, while choosing Western or East Asian partners could diversify Armenia’s external relations and financing sources. For a country that relies heavily on domestic generation from Metsamor, securing reliable and affordable electricity supplies is also a domestic priority.
Armenian authorities have indicated they will examine all options carefully before announcing a course of action. If Yerevan accepts Rosatom’s offer, the next steps would include detailed feasibility studies, regulatory clearances and negotiations on financing and project milestones. For now, the proposal represents a concrete offer that places a strategic energy decision squarely in the hands of the Armenian government.
