Russia’s nuclear industry stands as a paradox of strategic strength and operational vulnerability. As the world’s largest exporter of nuclear power plant technology, Rosatom simultaneously operates an aging domestic reactor fleet, faces unprecedented Western sanctions, and navigates the delicate balance between civilian energy ambitions and military-industrial priorities. The state corporation’s ability to maintain its global position while managing domestic pressures will shape the future of nuclear energy geopolitics for decades.
Domestic Operations: Aging Fleet, Ambitious Expansion
Russia currently operates 34 nuclear reactor units across 11 power stations, with a total net electrical capacity approaching 30 gigawatts. In 2025, these plants generated over 218 billion kilowatt-hours, with an average capacity factor of 87.22% — a figure that reflects strong operational performance despite the fleet’s average age of nearly 30 years. Nuclear power accounts for roughly 18-20% of Russia’s electricity mix.
The domestic construction pipeline is substantial. Rosatom is currently building 18 reactor units at nine sites within Russia, including large VVER-TOI and VVER-1200 units, as well as the BN-1200 fast reactor at Beloyarsk and small modular reactors. The long-term plan, embedded in Russia’s energy strategy through 2045, calls for 38 new units adding approximately 30 gigawatts of capacity, raising nuclear’s share of electricity generation to 25%. Putin has emphasized that nuclear power will expand into the Urals, Siberia, and the Far East, regions where reliable baseload capacity is needed for industrial development.
Rosatom’s Global Empire: 28 Reactors Under Construction Abroad
The centerpiece of Russia’s nuclear strategy is Rosatom’s international project portfolio. The state corporation is constructing 28 reactor units in nine countries — India, China, Turkey, Egypt, Iran, Bangladesh, Hungary, Uzbekistan, and Belarus. Beyond these, Rosatom has signed agreements for 17 additional units in six countries, including Vietnam, Kazakhstan, Myanmar, Kyrgyzstan, and Ethiopia, and is negotiating projects involving approximately 50 more reactors with 15 additional states.
This global footprint makes Russia the undisputed leader in nuclear technology exports. Putin noted in September 2026 that “we rank first in the world in the number of nuclear power units built abroad”. The flagship VVER-1200 Generation III+ reactor, with its 60-year design life, serves as Rosatom’s primary export product, already deployed in Turkey, Belarus, Bangladesh, Egypt, and Hungary.
The most recent major agreement came in September 2026, when Rosatom signed an EPC contract with Kazakhstan for the Balkhash Nuclear Power Plant — a two-unit, 2,400-megawatt facility that will be Kazakhstan’s first large-capacity nuclear station. This followed a March 2026 agreement to build Vietnam’s first nuclear plant, Ninh Thuan 1, and a June 2026 framework agreement with Laos for potential nuclear cooperation.
The Sanctions Paradox: Restricted Yet Indispensable
Western sanctions have targeted Russia’s nuclear sector, but their practical impact reveals deep contradictions in the global nuclear supply chain. The European Union has imposed export restrictions on nuclear-related goods and technologies, specifically targeting entities linked to Russia’s military-industrial complex, including the asset freeze on Rosatomflot. The United States passed the Prohibiting Russian Uranium Imports Act in 2024, banning imports of Russian low-enriched uranium, though waivers remain available through 2028 for utilities lacking alternative suppliers.
Yet Russia’s dominance in nuclear fuel services makes complete decoupling impractical in the near term. Russia controls approximately 44% of global uranium enrichment capacity, 25% of conversion services, and holds stakes in uranium mining operations, particularly in Kazakhstan, which produces nearly half of the world’s uranium. More than 80% of nuclear power plants in post-Soviet states and several Eastern European countries use Russian-designed reactors that rely on fuel enriched with Russian technology.
Even the United States, despite its import ban, has issued general licenses authorizing transactions related to civil nuclear energy with major Russian banks through December 2026, implicitly acknowledging the difficulty of immediately replacing Russian fuel supplies. As one analysis notes, “if Russian uranium were to disappear entirely from global trade, prices would likely surge sharply, calling into question the economic viability of nuclear energy under such conditions”.
Strategic Priorities: Dual-Use Technology and the Nuclear Shield
Rosatom’s leadership has been explicit about the corporation’s dual role in civilian energy and military applications. CEO Alexei Likhachev stated in September 2026 that Russia’s “nuclear-weapons complex has stepped far ahead” over the past two decades, transforming into “a stable channel for transferring technologies into civilian production”. Rosatom’s revenue has quadrupled over the past decade, with plans to reach 5.5 trillion rubles by 2030.
This integration of civilian and military nuclear capabilities raises concerns among Western policymakers. The EU’s sanctions framework specifically targets entities “linked to the Russian military-industrial complex,” reflecting the view that Rosatom’s civilian exports and military programs are deeply intertwined.
Russia’s strategic nuclear modernization programs, meanwhile, face their own challenges. The Sarmat intercontinental ballistic missile experienced another failed test in 2025, and the Burevestnik nuclear-powered cruise missile has a troubled development history despite claimed successful tests. The Oreshnik intermediate-range hypersonic missile, used against Ukraine with conventional warheads, has entered serial production, though volumes remain limited due to sanctions affecting precision manufacturing equipment.
Challenges: Sanctions, Delays, and Dependence
Despite its expansive project pipeline, Rosatom faces significant execution challenges. Western sanctions have complicated access to certain components, particularly computer numerical control machines and specialized equipment. The Borei-A-class submarine program has seen delivery delays due to inability to find replacements for imported components, with Russian-made substitutes not expected until 2028.
International projects have also experienced delays. The Akkuyu plant in Turkey and El Dabaa in Egypt — Rosatom’s flagship overseas projects — have both fallen behind schedule. Leaked documents have raised questions about Rosatom’s project management capabilities in Egypt, even as it simultaneously builds Hungary’s Paks II reactors. As one analysis bluntly put it: “Signing 50 more agreements is easier than pouring concrete on the 28 already under way”.
The expiration of the New START Treaty in February 2026 adds a layer of strategic uncertainty. Without binding limits on deployed strategic warheads, both Russia and the United States face pressure to expand their arsenals, potentially diverting resources and attention from civilian nuclear programs.
Conclusion: Strategic Strength, Tactical Vulnerability
Russia’s nuclear industry occupies a unique position in the global energy landscape. Its technological leadership in reactor exports and fuel cycle services remains unchallenged, and the 60-year contracts Rosatom signs with client states create durable dependencies that sanctions cannot easily sever. The corporation’s ability to operate across the full nuclear fuel cycle — from uranium extraction through enrichment, fuel fabrication, reactor construction, and spent fuel reprocessing — gives it a comprehensive advantage that no competitor currently matches.
Yet the industry’s domestic foundations show signs of strain. An aging reactor fleet, execution delays on major projects, sanctions-induced supply chain bottlenecks, and the competing demands of military modernization all constrain Rosatom’s capacity to deliver on its ambitious promises. The coming decade will test whether Russia can translate its technological advantages and global market position into sustained civilian nuclear leadership, or whether the structural challenges of operating under sanctions will gradually erode its competitive edge. For now, Russia remains indispensable to the global nuclear order — a position that provides both leverage and vulnerability in equal measure.
