Context This memo follows Team Korea’s nuclear opportunity under the US investment package, Hyundai E&C and Woojin in US nuclear expansion and construction EPC rerating.
TL;DR
The Westinghouse IP risk that could have blocked the Czech Dukovany 5 and 6 project has fallen meaningfully. Westinghouse, KEPCO and KHNP announced a global settlement on January 16, 2025, and the Dukovany contract was signed in June 2025.
That does not mean Korean nuclear exports are now free to expand across Europe without constraints. The remaining issue is economic: how much Westinghouse can take as a toll, how broad the reported market-access restrictions are, how much local content is required, and who carries fixed-price or schedule risk.
The confirmed project numbers are large. World Nuclear News reported the Dukovany 5 and 6 EPC contract for two APR1000 units at about CZK 407 billion, or USD 18.6 billion. KEPCO E&C announced an A/E services contract worth EUR 725 million, about KRW 1.2 trillion. Doosan Enerbility announced a KRW 320 billion steam turbine and turbine-control contract through Doosan Skoda Power.
The investment conclusion is simple: contract survival risk has fallen, but margin risk remains. The question has moved from “can Korea win and sign the project?” to “how much profit remains for Korea’s listed value chain after Westinghouse, localization and project risk?”
1. What Has Been Resolved
In August 2024, Westinghouse protested CEZ’s selection of KHNP as preferred bidder for the Dukovany project. Westinghouse argued that KHNP’s APR1000 and APR1400 designs used Westinghouse-licensed System 80 technology and that KHNP lacked the right to sublicense or retransfer that technology to CEZ and local suppliers. Westinghouse also raised US export-control issues under DOE Part 810.
The landscape changed on January 16, 2025. Westinghouse announced a global settlement with KEPCO and KHNP to resolve the IP dispute. The company said the agreement would allow both parties to move forward with new nuclear reactor deployment, while the terms remained confidential.
The US Department of Energy welcomed the settlement on the same date. CEZ’s Dukovany project page then confirmed that the contract for two new Dukovany units was signed in June 2025 after the legal injunction was lifted.
| Issue | Current state | Investment reading |
|---|---|---|
| Westinghouse IP dispute | Global settlement announced in January 2025 | The main legal obstacle to signing has fallen |
| Settlement terms | Confidential | Cost, market access and technology-independence risks remain |
| Dukovany 5 and 6 | Contract signed in June 2025 | The project is alive |
| EU foreign subsidy review | EC did not open an in-depth FSR investigation, according to KHNP/WNN | One regulatory risk has eased |
| EDF Czech litigation | EDF lost and said it would not pursue further Czech legal action | Tender-procedure risk has eased |
2. Why Westinghouse Did Not Simply Lose
The US court dismissal of Westinghouse’s Part 810 declaratory-judgment pathway should not be read as a full defeat on the economics. Finnegan’s legal analysis notes that the court found Part 810 did not give Westinghouse an independent judicially remediable right for that claim. It did not decide that Westinghouse’s broader contractual or IP economics were worthless.
This is why the settlement matters. Westinghouse may have moved from a legal blocker to an economic toll collector.
| Simplistic view | More accurate view |
|---|---|
| Westinghouse lost | The Part 810 court route was limited, but settlement economics may remain |
| Korea can export freely | Dukovany is open, but regional market access may still be constrained |
| IP risk disappeared | signing risk fell, but cost and margin risk remain |
3. The Reported Toll
Yonhap reported, citing industry sources, that KHNP may be restricted from new nuclear bids in North America, the EU, Britain, Japan and Ukraine, with the Czech Republic carved out as an exception. The same report said the agreement may require about USD 650 million of Westinghouse goods and services per exported reactor and about USD 175 million of technology license fees per reactor.
Korea Times also reported that the presidential office ordered a review of whether the KHNP, KEPCO and Westinghouse agreement followed proper legal basis and procedure.
These reported terms are not public settlement terms. They should be treated as reported but unconfirmed. Still, the direction is important.
| Reported condition | Meaning | Investment implication |
|---|---|---|
| USD 650 million of Westinghouse goods and services per reactor | Part of the headline order may flow to the US supply chain | Korean revenue capture is lower than headline EPC value |
| USD 175 million technology fee per reactor | IP toll | Project margin is reduced |
| Reported limits in North America, EU, UK, Japan and Ukraine | Czech project may be an exception, not a broad European beachhead | Do not extrapolate Dukovany into all-Europe TAM |
| Technology independence verification | New reactor or SMR exports may also face constraints | The premium for independent Korean exports should be moderated |
Using only the reported figures, two reactors would imply USD 1.65 billion of Westinghouse goods, services and license fees. Against a USD 18.6 billion project, that is roughly 8.9%. This is not a confirmed contract calculation, but it is a useful way to think about margin leakage.
4. Project Size Is Not Profit
World Nuclear News reported that the Dukovany 5 and 6 EPC contract covers two APR1000 units at a projected cost of CZK 407 billion, or USD 18.6 billion, with construction targeted to start in 2029.
That is a large project. But nuclear EPC value is not the same as shareholder value. The key variables are price escalation, localization, financing, schedule guarantees, delay penalties, equipment scope and Westinghouse-related costs.
| Driver | What to watch |
|---|---|
| Price | EPC value, escalation clauses, FX and inflation treatment |
| Quantity | Dukovany 5 and 6 plus possible Temelin options |
| Cost | Westinghouse toll, local content, fixed-price risk, financing and schedule guarantees |
The most common mistake is to buy the headline order while ignoring the cost stack.
5. Value Chain Implications
KEPCO E&C
KEPCO E&C is the cleanest direct exposure. It announced a EUR 725 million A/E services contract with KHNP for Dukovany 5 and 6, equivalent to about KRW 1.2 trillion. The scope includes A/E services, procurement support for auxiliary equipment and licensing activities for two 1,000-MW-class APR1000 units.
This gives KEPCO E&C direct design and licensing exposure. The next question is revenue recognition, staffing intensity, change-order scope and operating margin.
Doosan Enerbility
Doosan Enerbility announced a KRW 320 billion contract with Doosan Skoda Power for steam turbines and turbine-control systems for Dukovany 5 and 6. This is important because it combines Korean nuclear expertise with Czech local manufacturing through Doosan Skoda Power.
Doosan is the strongest beta to Czech nuclear equipment and potential Temelin follow-on work. But the stock already carries nuclear, SMR, gas turbine and AI-power narratives. Margin and follow-on contracts matter more than the headline.
Daewoo E&C
Daewoo E&C can be a construction exposure, but it needs more caution. Construction and EPC have large revenue potential, but also carry schedule, cost and delay-penalty risk. The key question is contract structure, not just participation.
| Company | View | Key check |
|---|---|---|
| KEPCO E&C | Watchlist | A/E revenue recognition, margin, change orders |
| Doosan Enerbility | Watchlist / Wait | Equipment margin, Temelin option, additional nuclear scope |
| Daewoo E&C | Watchlist | Fixed-price exposure, schedule risk and local partner split |
| KEPCO KPS, Woori Technology, Woojin | Follow-up candidates | Actual O&M, I&C or instrumentation contracts |
6. Catalysts And Invalidation
Upside catalysts:
| Catalyst | Meaning |
|---|---|
| Additional subcontract announcements | Korean listed value-chain capture expands |
| Clarity on Czech state-aid and financing structure | Financing risk falls |
| Temelin 3 and 4 options | Dukovany becomes a repeat project, not a one-off |
| KHNP-Westinghouse cooperation model | Market-access uncertainty may fall |
| Pre-2029 permitting, site and supply-chain milestones | Project execution risk falls |
Invalidation risks:
| Risk | Impact |
|---|---|
| Settlement terms are worse than reported | Korean nuclear export economics deteriorate |
| Fixed-price and schedule risk fall heavily on Korean parties | EPC and construction stocks de-rate |
| Temelin and broader Europe remain closed | Multiple expansion based on Europe TAM fades |
| Key subcontracting shifts to Czech or Westinghouse supply chains | Korean listed-company capture shrinks |
| Reported margins disappoint in quarterly earnings | Headline-order premium reverses |
Bottom Line
Dukovany is alive. The legal and procedural risks that could have blocked the contract have fallen. But the equity question has changed. Investors should no longer ask only whether Korea won the project. They should ask how much of the project becomes high-quality profit after Westinghouse tolls, localization, fixed-price risk and financing terms.
The best framing is:
Dukovany confirms Korea’s nuclear export survival. The next rerating depends on margin and repeatability.
