Korea Just Out-Built France in Europe's Biggest Nuclear Bet — Inside the $18.6 Billion Dukovany Deal
France's EDF took it to court to stop it. The Czech Supreme Court let it through anyway. This is how a country that once imported its first reactor from the West is now exporting them to the heart of Europe.
For most of the last century, nuclear power in Europe has been a French, Russian, or American story. So when the Czech Republic picked South Korea's state utility, KHNP, to build two brand-new reactors at its Dukovany plant — beating out France's EDF for the contract — it wasn't just a business deal. It was a signal that the club of countries who can build nuclear plants from scratch just got smaller, more competitive, and less European than it used to be.
The Contract That Made Nuclear History
The numbers alone are staggering: CZK 407 billion, or roughly $18.6 billion, for two APR-1000 reactors at Dukovany, units 5 and 6. KHNP isn't building this alone — it's leading "Team Korea," a consortium that includes KEPCO E&C for design, Doosan Enerbility supplying major equipment, Daewoo E&C on construction, KEPCO NF for nuclear fuel, and KEPCO KPS for commissioning and long-term maintenance. Construction is targeted to begin in 2029, with Czech companies — including turbine supplier Škoda Power — expected to grow their share of the work from 30% at the start to 60% by the time the reactors are finished.
Korea vs. France: How the Fight Actually Went
EDF didn't go quietly. The French utility challenged the tender process directly, alleging that KHNP's bid price and cost guarantees would be "unfeasible without illegal state aid" — essentially arguing Korea's price was too good to be legitimate. An injunction briefly froze the signing, but the Czech Supreme Court ultimately let the contract proceed, ruling that the public interest in finalizing the deal outweighed the pending dispute. The signing went ahead on June 5, 2025.
What makes this genuinely remarkable is the reversal it represents. Korea's very first commercial reactor, Kori-1, went online in 1978 using imported Westinghouse technology — Korea was the student, not the teacher. Fifty years later, the student is out-bidding the country that once supplied its neighbor's nuclear know-how, on that neighbor's own continent. That arc, more than the dollar figure, is the real story here.
From Barakah to Dukovany: Korea's Export Playbook
2009 — Barakah, UAE
Korea's first major nuclear export: four APR-1400 reactors, delivered on a schedule and budget that stunned an industry used to nuclear projects running years late and billions over.
2024–2025 — Dukovany tender won
KHNP wins the Czech tender over EDF; the contract survives a legal challenge and is signed in June 2025.
2026 — Steering committee expands scope
A joint ministerial committee meeting this year confirmed the project remains on track and, notably, expanded cooperation into robotics, EV batteries, and future mobility between the two countries.
2029 — Construction begins
Ground-breaking targeted for Dukovany units 5 and 6, with commissioning to follow through the years after.
The Barakah project is what actually earned Korea this Czech contract — not marketing, but a delivery record. In an industry notorious for cost overruns and multi-year delays, KHNP finishing all four UAE reactors close to schedule became the single strongest sales pitch Korean nuclear diplomacy has ever had. Dukovany isn't a lucky win; it's the second data point in a pattern the rest of the industry is now watching closely.
Why This Reaches Far Beyond Energy
The Dukovany deal was never going to stay confined to reactors. This year's steering committee meeting — marking the project's first anniversary — explicitly broadened the Korea-Czech relationship into robotics and electric vehicle battery cooperation, alongside continued technical work between Korea Electric Power Engineering & Construction and Czech firm EGP Praha. The Czech government's own policy of extending reactor lifespans to 80 years signals this isn't a one-off transaction; it's the opening chapter of a multi-decade industrial relationship between the two countries.
🎯 Key Takeaways
- KHNP's $18.6 billion contract to build two APR-1000 reactors at Dukovany is Korea's second major nuclear export after the UAE's Barakah project — and its first in Europe.
- Korea beat France's EDF for the tender, and the deal survived a legal challenge that reached the Czech Supreme Court before signing in June 2025.
- The partnership is already expanding beyond nuclear into robotics and EV batteries, suggesting a long-term industrial alliance rather than a single infrastructure contract.
Fifty years ago, Korea didn't have a single nuclear reactor of its own design. Today, it's the country a European Union member state picked over the country that arguably invented commercial nuclear power. Whatever happens with construction timelines between now and 2029, that shift in who's teaching whom is already permanent.
