In February 2022, Russia invaded Ukraine. In the months that followed, Russia systematically weaponized Europe's energy dependency - throttling gas flows through Nord Stream, creating artificial scarcity, driving prices to levels that threatened the economic viability of European industry.
The cost was staggering. EU member states spent over EUR 700 billion in emergency energy subsidies between 2022 and 2024. German industrial electricity prices tripled. Aluminium smelters shut down. Chemical plants idled. Steel production hit its lowest level since 1960. BASF, the crown jewel of German industry, announced it would permanently downsize operations in Ludwigshafen and shift investment to China.
Europe's energy dependency was not a secret. Analysts, intelligence agencies, and energy strategists had warned for decades that relying on Russian gas was a strategic vulnerability. Those warnings were ignored because the gas was cheap and the risk felt theoretical.
The risk is no longer theoretical. Europe has paid EUR 700 billion for that lesson.
The question is whether Europe has actually learned it - and more importantly, whether it applies the right lesson to the next chapter of energy technology.
China has the technology. Europe has the need.
China is 10-15 years ahead of the rest of the world in thorium molten salt reactor development. The TMSR-LF1 has been operating in the Gobi Desert since 2023. The 373 MW commercial TMSR-LF2 is planned for the early 2030s. Over 700 researchers at the TMSR Center in Shanghai are dedicated to nothing else. Over $3.3 billion invested since 2011.
No European country has an MSR development program at comparable scale. No European company has built a thorium reactor. No European regulator has licensed one.
This is a fact, not a failure. China made a strategic bet on thorium in 2011 and executed it with the institutional patience and concentrated resources that state-directed programs excel at. The physics is proven. The engineering data is being generated. The technology works.
The question for Europe is not whether to engage with the most advanced thorium MSR technology on earth. It is how.
The wrong lesson from 2022
The instinctive reaction after the Russian gas crisis is: never depend on anyone for energy again. Build everything domestically. Total self-sufficiency.
This instinct is understandable. It is also wrong - or at least, it is incomplete.
Europe did not fail with Russian gas because it engaged with Russia. It failed because it engaged passively - buying a commodity through pipelines without building any alternative capability, any leverage, any plan for what happens if the relationship changes. Germany built Nord Stream 2 while simultaneously closing its nuclear plants and letting its domestic energy technology stagnate. The dependency was not the engagement itself but the absence of any European capability underneath it.
The right lesson is not "never engage with foreign technology." The right lesson is: engage on terms that build your own capability, and never let engagement become dependency.
This distinction matters enormously for thorium.
Technology transfer done right vs. passive dependency
There are two fundamentally different ways Europe could access Chinese thorium MSR technology:
The wrong way: passive import
Buy turnkey Chinese reactors. Chinese design, Chinese components, Chinese IP, Chinese maintenance contracts. Europe provides the site and the electricity grid. China provides everything else.
This is the Huawei model applied to nuclear energy. It creates:
- Technology lock-in for the 40-60 year operational lifetime of the plants
- Supply chain dependency on Chinese materials (Li-7, Hastelloy-N equivalents, salt chemistry)
- Zero European capability development - you are a customer, not a partner
- Strategic leverage that China can exercise during any bilateral friction
This is the scenario that security hawks rightly warn about. And it is the scenario that Europe defaults into if it does nothing for another decade and then scrambles to deploy MSRs under time pressure.
The right way: strategic technology partnership
Engage with Chinese thorium MSR technology through structured technology transfer that builds European capability alongside deployment:
License the proven technology. China has spent $3.3 billion and 15 years proving that thorium MSRs work. Licensing this technology - rather than spending 15 years and EUR 25 billion reinventing it from scratch - is not weakness. It is strategic efficiency. Every other successful technology transfer in history worked this way. Japan licensed American semiconductor manufacturing. South Korea licensed Japanese shipbuilding. China itself licensed French nuclear technology (the CPR-1000 is derived from the French M310 design) and then developed indigenous capability on top of it.
Build European manufacturing from day one. The license covers the design. The manufacturing happens in Europe, using European companies, training European engineers. Every reactor built is a capability-building exercise. By the tenth unit, the European supply chain is mature. By the twentieth, it is independent.
Develop the supply chain in parallel. While the first reactors are being built under license, invest in European Li-7 enrichment, European Hastelloy-N production, European FLiBe salt manufacturing. The licensed technology creates the demand signal that justifies the supply chain investment. Without reactors being built, the supply chain investment has no customer.
Invest in European R&D on top of the licensed base. Use the operational experience from licensed reactors to develop next-generation European improvements - better materials, more efficient reprocessing, advanced safety systems. The license gives you the starting point. European engineering gives you the trajectory.
Train a generation of European MSR engineers. Building, operating, and maintaining licensed reactors creates exactly the workforce that Europe needs. Learning by doing, on real reactors, with real salt chemistry, is worth more than any university program alone.
This is the model that built South Korea's nuclear industry. Korea licensed Westinghouse PWR technology in the 1970s, built Korean manufacturing capability around it, trained Korean engineers through construction and operation, and within 30 years had developed the indigenous APR-1400 design that Korea now exports globally. Korea went from licensee to competitor to exporter in one generation.
Europe can do the same with thorium MSR technology - but only if it starts now, while the technology is still early enough that partnership terms are favorable.
The window of leverage
This is the point that most analysts miss: the terms of technology transfer depend on timing.
Right now (2026), China's TMSR program is still experimental. The TMSR-LF1 is 2 MW. Commercial deployment has not begun. China has the technology but not yet the commercial track record. A European partner bringing capital, industrial manufacturing capability, and access to the world's most regulated and demanding energy market is genuinely valuable to China.
In 2035, if China has deployed commercial MSRs domestically and is exporting the technology to Belt and Road countries, the leverage shifts entirely. China no longer needs a European partner. Europe becomes just another customer. The terms will reflect that.
The window for partnership on favorable terms - where both sides bring something the other needs - is open now. It will not stay open indefinitely. Every year of European inaction is a year of Chinese capability growth that shifts the negotiating balance.
This is not an argument for rushing into a bad deal. It is an argument for engaging now, from a position of relative strength, to secure terms that build European capability rather than European dependency.
The uranium dependency problem today
The thorium conversation is not happening in a vacuum. Europe already has a nuclear fuel dependency problem with its existing reactor fleet.
Russia's Rosatom supplies approximately 20% of global uranium enrichment services and roughly 35% of European enrichment specifically. Kazakhstan - firmly in Russia's sphere of influence - supplies approximately 40% of global uranium mining output.
When Europe imposed sanctions on Russia after the 2022 invasion, nuclear fuel was explicitly carved out. Not because European governments wanted to exempt Russia, but because they had no choice - European reactors literally cannot operate without Russian enrichment services in the near term.
The irony is bitter. Europe sanctioned Russian oil, Russian gas, Russian coal - but continued buying Russian nuclear fuel because the dependency was too deep to sever quickly.
Thorium changes this equation fundamentally:
- Fuel abundance: Thorium is 3-4x more abundant than uranium in the Earth's crust. Europe has significant deposits in Norway, Sweden, Finland, and France. No imports required.
- Reduced enrichment: The thorium fuel cycle breeds U-233 in-situ. You do not need the massive enrichment infrastructure that the uranium cycle requires - the same infrastructure that makes Europe dependent on Rosatom.
- Fuel longevity: Thorium breeding means the reactor produces more fuel than it consumes over its lifetime. A single fuel load, with online reprocessing, lasts the life of the reactor.
Moving to thorium MSRs does not just improve European energy economics. It eliminates the uranium supply chain vulnerability that European governments are currently unable to address. And European thorium reserves mean the fuel itself is truly domestic.
What strategic autonomy actually requires
"Strategic autonomy" does not mean building everything from scratch in isolation. That is autarky - and autarky is expensive, slow, and unnecessary. Strategic autonomy means having the capability to operate independently if you need to, while engaging with partners when it is advantageous.
In the context of thorium MSR technology, strategic autonomy requires five capabilities that Europe must build - whether it starts from licensed technology or from scratch:
1. European manufacturing capability
Regardless of where the design originates, the reactors must be built in Europe by European companies. This means European factories producing reactor vessels, salt loop components, heat exchangers, and instrumentation. Manufacturing is where capability lives. Design can be licensed. Manufacturing cannot be outsourced without losing the capability.
2. Domestic fuel cycle capability
Thorium processing, salt chemistry, and online reprocessing must happen in Europe. This includes thorium extraction from European mineral deposits (Norwegian and Swedish monazite sands), FLiBe salt production, and reprocessing chemistry. The fuel cycle is where energy independence lives - if you control your own fuel, no one can turn off your reactors.
3. Domestic materials supply chain
Li-7 enrichment is the most urgent capability gap. Europe currently has zero production. Building a European Li-7 enrichment facility using modern techniques should be treated as emergency critical infrastructure. Similarly, European Hastelloy-N production at nuclear grade and FLiBe salt manufacturing must be developed. These supply chains can be built in parallel with reactor construction - the first reactors may use imported materials, but by the fifth or tenth unit, the European supply chain should be operational.
4. Regulatory sovereignty
European reactors must be licensed under European safety standards by European regulators. This is non-negotiable regardless of design origin. ASN (France), SUJB (Czech Republic), STUK (Finland) - European regulators must conduct independent, thorough safety assessments. A licensed Chinese design reviewed and approved by ASN is categorically different from a Chinese design deployed under Chinese safety standards. The regulatory review is where sovereignty is exercised.
5. Human capital
Europe needs a generation of MSR engineers, salt chemists, materials scientists, and nuclear safety analysts. The fastest way to train them is through building and operating real reactors. A technology transfer programme that puts European engineers on the shop floor, in the control room, and at the chemistry bench from day one creates the workforce that European independence requires.
The critical insight: all five of these capabilities are built faster through structured technology transfer than through starting from scratch. You learn more by building a licensed reactor than by spending 15 years designing one in a laboratory.
The defense and security dimension
Proliferation resistance
The thorium fuel cycle has an inherent proliferation advantage over the uranium-plutonium cycle. U-233 produced in thorium reactors is contaminated with U-232, which decays through a chain that produces intense, penetrating gamma radiation. This makes U-233 extremely difficult to handle for weapons purposes.
This proliferation resistance is a strategic advantage for European thorium deployment. It simplifies safeguards requirements, reduces the political sensitivity of reactor technology, and strengthens the non-proliferation case.
Energy as statecraft
The 2022 energy crisis demonstrated that energy supply is a tool of statecraft. Russia used gas dependency to pressure European policy. China uses rare earth export controls to pressure trade policy.
The strategic imperative is not to avoid all engagement - it is to ensure that engagement builds mutual dependency, not one-sided vulnerability. A structured thorium partnership where China provides design IP and Europe provides manufacturing, capital, and market access creates balanced interdependence. Both sides have something to lose from disruption. That balance is the foundation of stable strategic relationships.
Compare this to passive dependency where Europe provides only money and China provides everything else. That is the Russian gas model. The goal is to never repeat it.
Naval and military applications
Small MSRs have potential military applications that France and the UK should be evaluating - compact naval reactors, forward operating base power, and logistics simplification. These applications will always require domestically developed technology. But the fundamental MSR engineering knowledge gained from a civilian technology transfer programme directly enables future domestic military applications.
What Europe should do
1. Engage now on technology partnership
Identify and structure a technology transfer partnership for thorium MSR technology while European leverage is still strong. This means engaging with SINAP/CAS and the Chinese TMSR programme through a framework that specifies: European manufacturing, European regulatory review, European supply chain development, and progressive IP transfer.
The terms get worse every year Europe waits. The TMSR-LF2 commercial deployment in the early 2030s is the inflection point. Before that, China benefits from European partnership. After that, China can go it alone.
2. Build the supply chain in parallel
Treat European Li-7 enrichment capability as emergency critical infrastructure. Begin Hastelloy-N nuclear-grade production scaling at VDM Metals (Germany) and potentially new facilities. Establish European FLiBe salt manufacturing. These investments are justified regardless of design origin - every MSR deployed in Europe needs these materials.
3. Invest in European R&D on top of the licensed base
Fund European research programmes that build on operational experience from licensed reactors. Next-generation materials, improved reprocessing, advanced safety systems, European design improvements. The goal: within 15-20 years, Europe has its own indigenous MSR design - developed from operational knowledge, not from theory.
4. Create the regulatory framework
European regulators must develop MSR licensing capability now. Technology-neutral safety frameworks, pre-licensing assessment programmes, and MSR-specific regulatory expertise. This investment is needed regardless of where the reactor design comes from - and it is the foundation of regulatory sovereignty.
5. Use Euratom
The European Atomic Energy Community was created in 1957 explicitly for this purpose - coordinating European nuclear energy development. Its mandate, budget, and institutional infrastructure are ready. A European thorium MSR programme is exactly what Euratom was designed for.
The Korea model
South Korea's nuclear industry is the clearest precedent for what Europe should do with thorium.
In the 1970s, Korea had no nuclear capability. It licensed Westinghouse PWR technology, built Korean manufacturing around it, trained Korean engineers through construction and operation, and invested in Korean R&D to improve and eventually supersede the licensed design.
Within 30 years, Korea developed the APR-1400 - an indigenous design that Korea now exports globally. The UAE's Barakah nuclear plant, the largest nuclear construction project in the world, uses Korean APR-1400 reactors. Korea went from licensee to competitor to exporter in one generation.
The timeline:
- 1970s: License foreign technology, build first reactors under technology transfer
- 1980s: Localize manufacturing, train domestic workforce
- 1990s: Develop indigenous design improvements
- 2000s: Launch fully indigenous APR-1400 design
- 2010s: Export to global markets
Europe can replicate this trajectory with thorium MSR technology. License proven Chinese TMSR technology. Build European manufacturing. Train European engineers. Develop European improvements. Export European designs.
The alternative is spending 15-20 years and EUR 25 billion reinventing what already exists - and arriving at commercialization just as China has already captured the global market.
The real choice
Europe does not face a binary choice between total self-sufficiency and passive dependency. That framing is a trap that leads to either decades of expensive reinvention or reckless technology import.
The real choice is between three paths:
Path one: Strategic technology partnership. Engage with Chinese TMSR technology now, on structured terms that build European capability. License the design, manufacture in Europe, build the supply chain, train the workforce, develop indigenous improvements. Reach European MSR capability in 10-15 years. Cost: EUR 5-10 billion. Timeline: competitive with China's commercial deployment.
Path two: Total domestic development. Start from scratch. Rebuild 15 years of Chinese R&D in European laboratories. Spend EUR 15-25 billion over 15-20 years. Arrive at commercialization in the late 2030s or 2040s - a decade after China has deployed commercial units and captured the export market.
Path three: Do nothing. Wait until the 2030s. Realize Europe needs thorium MSRs. Buy Chinese technology on Chinese terms with no European capability, no leverage, and no alternatives. The Russian gas model applied to nuclear energy.
Path one is faster, cheaper, builds genuine European capability, and preserves European leverage. It requires the strategic maturity to engage with Chinese technology while building independence - the same approach that Korea, Japan, and China itself used to build world-leading technology industries.
Path two is ideologically pure but strategically inferior - spending more time and money to arrive at the same destination later.
Path three is unacceptable.
The physics does not care about politics. The technology exists. The question is whether Europe accesses it through strategic partnership that builds capability - or waits until the only option is passive dependency.
The window for path one is open now. Every year it narrows.
Someone needs to walk through it.
