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.
