Strategy for the development of energy using new clean sources (fusion, mini nuclear reactors)

1. Invest in research and development of advanced nuclear fusion
Fund fusion projects at national and international level (e.g. ITER, China's own EAST, HL-2M projects).

Support the development of materials and technologies that can cope with the extreme conditions of fusion reactors.

Work with academia and the private sector to accelerate the transition from experimental facilities to industrial fusion plants.

Develop and deploy small modular nuclear reactors (SMRs)
Develop and certify SMRs that are safer, cheaper and more flexible than traditional large nuclear power plants.

Enable decentralised power generation close to consumption, e.g. in remote regions or industrial sites.

SMRs can also be used for heat generation (for industrial processes, heating) and as a backup source in hybrid energy systems.

3. Integrate fusion and SMRs into the overall renewable mix
Combine fusion and SMRs with renewables (solar, wind, hydro) for a stable and flexible electricity supply.

Create smart grids that dynamically manage generation and consumption according to resource availability and demand.

4. Strengthen energy security and independence
Reduce dependence on fossil fuels and energy imports.

Build strategic stocks of fuels and components for fusion and nuclear reactors.

Diversify supply chains and create our own industry for the production of key equipment.

5. Economic support and regulation
Introduce incentives for investment in fusion technologies and SMRs (tax breaks, grants, government guarantees).

Establish a regulatory framework to ensure safety, environmental standards and public confidence.

Promote international cooperation and export of technology.

6. Training and human resources development
Train specialists in nuclear physics, engineering, materials science and fusion plant operations.

Involve universities in research and teaching of new technologies.

Establish programmes for the transition of workers from the traditional energy sector to new fields.

STRATEGIC PROPOSAL

(within the Three Seas region):

1. CREATE A REGIONAL ENERGY EXCHANGE FOR THE THREE SEAS

Instead of Leipzig: our own regional exchange within the Three Seas region.

Access only for Three Seas countries, with direct contracts between them.

Each state retains part of its production outside the exchange for domestic consumption.

Model: for example, Hungary has the HUPX exchange, where only domestic players trade.

2.  ESTABLISH REGIONAL ELECTRICITY PACTS (bilateral agreements)

Examples:

Czechia ↔ Slovakia
Poland ↔ Hungary
Austria ↔ Croatia

 Agreements to share electricity surpluses at fair prices, without the intermediary (Leipzig).

3. SUPPORT REGIONAL POWER PLANTS

a) NUCLEAR:

• Slovakia has new reactors Mochovce 3 and 4

• Poland is planning new reactors with the USA

• Hungary is building Paks II with Rosatom

       The Three Seas region will have sufficient nuclear capacity by 2030

b) SMALL MODULAR REACTORS (SMR):

• Pilot projects e.g. in Romania (NuScale)

• Support for SMR development across the Three Seas

• Creation of a common “Three Seas Nuclear Alliance”

4.  BUILD DIRECT POWER CONNECTIONS

Avoiding Germany. Examples:

• Direct cable Czechia–Hungary

• Restoration of Czechia–Poland lines

• Slovakia ↔ Romania via Ukraine

Every new line = independence from the western market

5.  DIGITAL PLATFORMS FOR CITIZENS AND BUSINESSES

Establish a regional P2P market:

Households and businesses will be able to buy electricity directly from other users in the Three Seas region via digital platforms.

 Bypass the big players, ensure fair prices

OUTCOME:

 Domestic electricity at fair prices for domestic citizens
Restored control over pricing
Regional solidarity
Diversification beyond Germany
Energy security

A Science‑Based Energy Strategy for the Three Seas Initiative

Leveraging Czech Thorium‑MSR Research – A Post‑2050 Vision

Executive Summary
This strategy outlines a realistic path for Three Seas (3SI) member states to achieve full energy sovereignty using thorium Molten Salt Reactors (MSRs). However, thorium MSRs are not an immediate solution. They will only be deployed after a first wave of micro‑nuclear reactors (very small modular reactors, typically below 20 MWe) that can enter the market before 2035. Consequently, the first commercial thorium‑based MSRs in the Three Seas region will appear after 2050, acting as the backbone of a fully decarbonised, independent energy system in the second half of the century. The strategy builds on unique Czech research (CVŘ, LR‑0 reactor, Energy Well concept) and on the operational success of China’s TMSR‑LF1. By 2065, thorium MSRs could cover 60 % of electricity and 40 % of district heating in the region, while eliminating the need for imported uranium or fossil fuels.

1. Introduction: Why the Three Seas, and Why Thorium MSRs – But Only After Micro‑Nuclear

“Energy security equals security.” – Kolinda Grabar‑Kitarović

The Three Seas Initiative faces a clear energy dilemma: most member states depend on imported uranium and natural gas. Today’s light‑water reactors guarantee long‑term dependence on foreign fuel. Thorium MSRs (4th generation) offer a way out – but they are not ready for immediate commercial deployment.

The logical sequence is:
- Step 1 – Micro‑nuclear (2026–2045) → small modular or even micro‑reactors (e.g., NuScale, Rolls‑Royce SMR, Oklo Aurora) provide the first wave of local, clean capacity, repower coal sites, and build a nuclear supply chain.
- Step 2 – Thorium MSRs (after 2050) → once the nuclear ecosystem is mature, thorium MSRs replace most conventional reactors, add highly efficient heat‑and‑power, and make the region independent of any fuel imports.

This strategy focuses on Step 2, but always in the context of a transitional phase where micro‑nuclear units prepare the ground.

Why the Three Seas is the ideal birthplace for European thorium MSRs:

• Unique Czech know‑how – Centrum výzkumu Řež (CVŘ) has been developing the Energy Well MSR concept for over 15 years, owns samples of FLiBe salt from the original US MSRE, and operates the LR‑0 experimental reactor. This is the only active MSR research programme in the 3SI region.

• Geopolitical window – China started its TMSR‑LF1 (2 MWth) in 2023 and received a commercial licence in 2024. The West cannot afford another lost decade.

• Abundant domestic thorium – Minor deposits exist in the Czech Republic, Poland and Slovakia. With efficient breeding, these can fuel the region for centuries without any foreign supplies.

2. Technical Status – What We Already Know (and What Is Missing)

• Proven concept: China’s TMSR‑LF1 demonstrated stable operation, online refuelling, and on‑site conversion of thorium‑232 into fissile uranium‑233. No pressurised vessel, no meltdown risk.

• Key advantages over conventional SMRs:

  • Fuel autonomy – thorium is abundant in 3SI countries.

  • Superior safety – the molten fuel passively drains into subcritical drain tanks.

  • Little long‑lived waste – transuranic elements are orders of magnitude lower.

  • High‑temperature heat (700 °C) – electric efficiency ~45 % + industrial heat + hydrogen production.

Remaining challenges before 2050:

• Corrosion‑resistant alloys (nickel‑based, e.g., Hastelloy‑N) must be qualified for decades of operation.

• Online chemical processing of the fuel salt (removal of fission products, addition of fresh thorium) needs industrial‑scale demonstration beyond today’s lab setups.

• Licensing framework – no European country yet has rules for liquid‑fuel reactors. The EU’s upcoming SMR certification (expected by 2040) will be a prerequisite.

3. Regional Map – Who in the Three Seas Is Already Preparing?

CountryCurrent micro‑nuclear / SMR activityRelevance for future thorium MSRs

Czech RepublicEnergy Well MSR R&D; LR‑0 reactor; cooperation with US DOE (since 2012)Primary technology holder, salt chemistry and materials testing

PolandContracts with NuScale (SMR); US nuclear deal 2025; repowering coal sitesManufacturing base, first operating SMRs (post‑2035)

SlovakiaSpent fuel research; SMR readiness studiesPotential shared fuel cycle and maintenance hub

RomaniaSMR feasibility at former coal plants; cooperation with US and CanadaLikely host for thorium MSR pilot after 2050

HungaryPaks II extension (VVER) – but open to SMRs after 2040Future grid integration for MSR heat

By 2045, all these countries will have operational micro‑nuclear units (5–50 MWe each). This creates the supply chains, trained personnel, and regulatory experience needed for thorium MSRs.

4. Revised Timeline – Thorium MSRs Only After 2050

All dates are conservative and assume that micro‑nuclear (e.g., 10–100 MWe SMRs) will be deployed first, starting around 2030–2035. Thorium MSRs follow as a second wave – no earlier than 2050.

PhasePeriodKey milestonesEstimated cost (shared)

1 – Micro‑nuclear roll‑out & MSR certification2026–2045Deployment of ~50 micro‑nuclear units across 3SI; EU licensing framework for MSRs; completion of Czech Energy Well validation.2–3 bn € (national and EU funds)

2 – Thorium MSR pilot unit2046–2055Construction of first commercial thorium MSR (100 MWe) at a repowered coal site in Poland, Romania or the Czech Republic. Start of operation ~2053–2055.300–400 m € (FOAK)

3 – First wave of regional thorium deployment2056–207010–15 thorium MSR blocks (100–150 MWe each) in 4‑5 countries. Shared fuel‑salt processing centre.1.0–1.5 bn € per unit (falls with serial production)

4 – Full maturity2071–208560+ thorium MSR modules covering 60 % of electricity and 40 % of heat in the Three Seas region. Complete phase‑out of imported uranium and fossil fuels.0.7–1.0 bn € per unit (NOAK)

Note on micro‑nuclear first: The transition begins with already‑certified SMRs (e.g., NuScale, Rolls‑Royce, Westinghouse AP300) and micro‑reactors (Oklo, Ultra Safe). These will provide the grid stability, repower coal plants, and build the “nuclear culture” needed for MSRs. Thorium units will replace many of those first‑generation SMRs after 2050, offering higher fuel efficiency and lower waste.

5. Energy Independence and Self‑Sufficiency

• Zero fuel imports – Thorium is mined and processed inside 3SI. No more uranium from Russia, Kazakhstan, Niger, or Canada.

• Resilience to water scarcity – MSRs use molten salt as coolant; they need little water, unlike conventional nuclear or coal plants. This is critical for drier regions of Poland, Hungary and the Czech Republic.

• Sector coupling – MSRs produce 700 °C heat, ideal for:

  • District heating (replace coal boilers).

  • Hydrogen via thermochemical cycles (e.g., iodine‑sulphur) at >40 % efficiency – without electrolysis.

  • Synthetic fuels (methanol, ammonia) for shipping and aviation.

By 2080, the Three Seas could become a net exporter of clean electricity and hydrogen to Western Europe, while having zero dependence on external energy sources.

6. Financing and Return on Investment

Even with a post‑2050 deployment, thorium MSRs can be highly profitable because fuel costs are negligible and lifetime exceeds 60 years.

• Target LCOE (levelised cost of electricity) for serial thorium MSRs: 40–60 €/MWh (in 2050 euros). This is cheaper than any fossil or renewable alternative with firm capacity.

• Payback period (first of a kind pilot): 15–18 years. Subsequent units: 8–10 years.

• Funding sources for the 3SI region:

  • 3SIIF (Three Seas Investment Fund) – could allocate €5 bn for the first two thorium MSRs.

  • EU Innovation Fund – will still be active after 2050, supporting breakthrough low‑carbon tech.

  • Private capital – pension funds and sovereign wealth funds will invest in long‑lived, zero‑carbon assets with guaranteed CfDs (Contracts for Difference).

7. Emissions and Climate Impact

• Deep decarbonisation – Full thorium MSR deployment (phase 4) abates 200 Mt CO₂/year by 2080 – equivalent to retiring all remaining coal and gas plants in the 3SI region.

• No methane leakage – Unlike natural gas, thorium MSRs produce zero methane (a potent GHG) during operation.

• Land use – A 100 MWe thorium MSR requires <2 hectares – orders of magnitude less than solar or wind for firm power.

8. Recommendations for the Three Seas Initiative

1. Launch a “Micro‑Nuclear First” programme (2026–2035) – accelerate deployment of certified SMRs to build the nuclear workforce and supply chains.

2. Establish the “Three Seas Thorium Office” (3STO) by 2030 – a joint R&D and licensing body that prepares the legal framework for MSRs, based on Czech research.

3. Secure a thorium inventory – map all exploitable thorium resources in Poland, Czechia and Slovakia; develop a regional mine‑to‑salt processing pilot by 2040.

4. Include thorium MSRs in the 3SI Energy Security Agenda – as a long‑term pillar (post‑2050), not a distraction from today’s micro‑nuclear deployment.

Conclusion – A Two‑Wave Strategy for European Energy Leadership

The Three Seas cannot leapfrog directly to thorium MSRs. Micro‑nuclear (SMRs) must come first – by 2035–2045 they will provide the carbon‑free capacity, local jobs, and regulatory experience. Then, after 2050, thorium MSRs will take over: they will finally cut the last ties to imported uranium and fossil fuels, deliver cheap heat and hydrogen, and make the Three Seas the most energy‑sovereign region in the developed world. This is not a fantasy – it is a logical, stepwise transition based on real Czech science and a realistic reading of technology readiness levels.
