EDF Plans 10 SMRs Across Five Countries in €10bn Nuclear Push

EDF has put a number, a map, and a deadline on Europe’s small modular reactor ambitions. Its Nuward subsidiary is proposing to build ten reactors across five countries for more than €10 billion, with first power targeted for 2035.

That specificity is what separates this from the wave of nuclear pledges that came before it. Named countries, named partners, and a firm euro figure move the conversation from concept to commitment.

The timing carries weight. Italy has not run a nuclear plant since a 1987 referendum shut the door, and its legislature has only recently voted to reopen it, making the country a symbolically charged second site in a programme launched into Europe’s post-Ukraine hunt for firm, weather-independent low-carbon power.

Here is what the announcement actually commits to, what remains conditional, and what the gap between the two tells you about where European nuclear is heading. This is substantive, but it is not settled.

EDF’s Nuward arm sets out a ten-reactor, five-country blueprint

EDF and its partners have laid out a first series of ten Nuward reactors spread across France, Italy, Poland, Belgium, and Finland, with construction slated to begin in 2030 and first electricity flowing by 2035. The first unit is destined for France; the second for Italy.

Nuward itself is an EDF subsidiary established in 2023 to develop and commercialise a small modular reactor for European markets. Its design is a pressurised water reactor, the same fundamental technology used in most of the world’s operating plants, rated at up to 400 MWe per unit and built to supply both electricity and industrial heat.

The programme’s two most telling markers are financial and mechanical. The first series carries a stated price tag of more than €10 billion, and Nuward estimates each unit can be installed within a four-year window, according to reporting from Reuters, Milano Finanza, and Il Sole 24 Ore on 18 September 2026.

The five target countries are:

• France (first unit)
• Italy (second unit)
• Poland
• Belgium
• Finland

That detail matters. A programme that names five host countries, a specific investment quantum, and industrial partners including Edison is seeking contractual and financing commitments, not circulating a feasibility study.

The distinction shapes how seriously you should take the timeline. Most SMR announcements over the past few years have stalled in the feasibility stage. Whether this one stays as specific as it currently reads is the live question, and it is the question the rest of the programme now has to answer.

Italy’s return to nuclear: what the legislation actually says, and what it does not yet settle

Italy’s presence on that map of five countries rests on a legislative shift that is real but incomplete. To understand the schedule risk, you need to see exactly how far the country’s nuclear re-entry has actually progressed.

The historical background

Italy walked away from nuclear power after a referendum in 1987, and a ban has held for nearly four decades. That history is why any re-entry carries political charge well beyond the engineering.

Italy’s energy security position is complicated by its decision to extend coal plant operations until 2038, a move that reflects the gap between decarbonisation ambition and the firm-capacity deficit that nuclear re-entry and the Nuward programme are in part designed to close.

The current move began in early 2025. Reuters reported on 28 February 2025 that the government adopted a law opening the path back to nuclear energy, handing ministers a mandate to draft the detailed decrees that would govern new reactor deployment.

Where the bill stands now

The lower house has since acted. World Nuclear News reported that on 4 June 2026 the Chamber of Deputies passed a bill on sustainable nuclear power.

Chamber of Deputies vote, 4 June 2026: 155 in favour, 86 against, 8 abstentions.

The measure, draft law A.C. 2669, empowers the government to regulate sustainable nuclear power, establish an independent Nuclear Safety Authority, and develop a National Programme for Sustainable Nuclear Power. It explicitly covers SMRs, advanced modular reactors, and micro-reactors, all framed within EU decarbonisation and energy security objectives, according to a legal briefing from Italian firm Gianni & Origoni.

What has not been confirmed is the finish line. After the lower-house vote, the bill passed to the Senate, and the government stated it expected final approval before the summer recess at the end of July 2026. Publicly available reporting does not confirm that vote took place.

Reporting from Gazzetta del Mezzogiorno on 21 September 2026 indicated that the Italian Senate vote on the nuclear bill was scheduled for that Wednesday, with a probable final approval expected in the afternoon, which would also trigger the government’s mandate to issue implementing decrees.

There is a further step beyond even Senate passage. The delegation law requires the government to issue implementing decrees within 12 months of final passage, meaning the framework does not become operational the moment the Senate signs off.

For you, tracking the Italian unit, this is where the schedule risk concentrates. A bill that has cleared the lower house but not completed ratification or produced its operating decrees puts Italy closer to a nuclear future than it was, without yet giving Nuward the fully operational regulatory host its Italian reactor would need.

Why European utilities are betting on smaller reactors now

Italy’s willingness to reopen the door is one instance of a broader shift, and that shift is not driven by any single argument. Three reinforcing pressures are pulling European utilities toward smaller reactors at the same time:

• Energy security after the Ukraine shock
• Grid integration in a high-renewables system
• A capital and financing structure that spreads risk

Take energy security first. European governments, jolted by the disruption to imported fossil fuels, have looked to nuclear both to reduce that dependence and to rebuild domestic capacity in advanced clean technology. EDF, Nuward, and Edison have explicitly positioned the SMR as a European-manufactured product tied to EU and Italian industrial supply chains, which is the point where energy policy and industrial policy meet.

The grid argument is structural, not just a cost pitch. At 300-400 MWe with the ability to load-follow, meaning the reactor can raise and lower output to match demand rather than running flat out, an SMR fits a grid full of variable wind and solar better than a fixed 1,600 MWe baseload plant. Nuward’s dual electricity-and-heat output widens where it can plausibly be deployed.

Nuward’s dual electricity-and-heat output is the feature that opens the door to industrial heat applications including steel production, chemical processing, and desalination, markets where firm high-temperature supply is both technically necessary and commercially distinct from what variable renewables can offer.

Then there is the money. Smaller units mean lower absolute capital per project, phased deployment over time, and factory-built components, and a multi-country consortium spreads exposure that a single gigawatt-scale build would concentrate.

The International Energy Agency argues that nuclear, including SMRs, can lower system-level decarbonisation costs by supplying firm low-carbon power that complements variable renewables and reduces reliance on gas.

The EU taxonomy’s conditional inclusion of nuclear adds a further layer of regulatory clarity for institutional investors weighing exposure.

What you should take from this is the multi-factor logic itself. Previous SMR hype waves leaned on a single promise, usually cost. This one addresses grid fit, financing, and policy at once, and that convergence is what makes the current cycle harder to dismiss.

What could derail the 2030-2035 window

The case against the timeline deserves the same precision as the case for it. The risks here are not vague cautions; they attach to identifiable milestones, in roughly this order of proximity to the schedule:

1. Regulatory and licensing timelines
2. Cost-per-MWh uncertainty
3. The precedent set by prior SMR cancellations

Regulatory risk sits closest to the immediate schedule. European nuclear licensing, covering generic design approvals, environmental assessments, and public consultation, has historically run for years even for proven technology, as the UK’s Generic Design Assessment process and France’s own EPR approvals show. Nuward’s reactor, despite resting on established pressurised water technology, must still satisfy full nuclear safety standards. Italy compounds this: the country must first stand up the new Nuclear Safety Authority its own bill mandates before it can license anything at all, an institution that does not yet exist.

Cost is the second variable. The €10 billion figure covers all ten units but carries no firm cost-per-MWh, and competitive economics depend on serial production and learning-curve effects that only materialise if the full series proceeds on schedule. Slip the timeline or build fewer units, and the per-unit cost logic weakens.

Commercial risk and the NuScale lesson

The clearest warning is recent and specific. NuScale‘s Carbon Free Power Project in the United States was cancelled in 2023 after cost estimates climbed and the utilities meant to buy the power withdrew. It is the most-cited real-world case of an SMR business model failing before a single commercial unit was built.

The cancellation is not evidence that Nuward will follow the same path. It is a structurally similar case that tells you what the failure mode looks like: procurement risk and cost escalation converging before construction.

Nuward carries mitigants NuScale lacked. Its risk is spread across five countries, its partners are state-backed utilities, and it sits inside explicit EU industrial policy rather than relying on a single merchant customer.

Even so, cautionary assessments from Reuters, the Financial Times, and think-tank analysts, informed by the cost and schedule histories of Flamanville, Olkiluoto, and Hinkley Point C, are worth holding. Energy analysts broadly describe the 2030-2035 window as possible but contingent, which is the honest reading.

The IAEA global SMR outlook, updated for the sixth consecutive time in 2026, shows accelerating deployment projections across both advanced economies and emerging markets, providing the independent benchmark against which claims like Nuward’s 2035 first-power target can be calibrated.

What a 2035 first-power date would mean for European energy markets

Set the risks aside for a moment and ask the other question: if this does land, what actually changes? Ten units at up to 400 MWe each add up to roughly 4,000 MWe of firm low-carbon capacity delivered to European grids in a single construction wave.

Collective capacity of the first Nuward series: up to 4,000 MWe of firm, dispatchable low-carbon power.

At the grid level, that figure is relevant to displacing gas peaker plants and stabilising supply, but on its own it is not transformative across a continent. The larger consequence is industrial. EDF and its partners have tied Nuward to European manufacturing, so a successful first series would establish an SMR supply chain, licensing precedent, and operating experience with export potential.

Advanced reactor deployment across the United States, Canada, and South Korea in 2025-2026 has generated a new body of licensing, supply chain, and construction-schedule evidence that European programmes including Nuward can draw on when calibrating their own cost and timeline assumptions.

That is why the milestones before 2035 matter more than the first-power date itself. Three are worth watching:

• Senate passage in Italy and the implementing decrees that follow
• Site selection confirmations in Poland, Belgium, and Finland
• Nuward’s commercialisation milestone, targeted before 2029

The commercialisation checkpoint is the earliest read on credibility. If you are tracking European energy infrastructure, the value of this programme lies less in the 4,000 MWe it might add and more in the manufacturing and regulatory foundation it would leave behind, a foundation that would shape the following decade of nuclear deployment across the bloc.

Ten reactors, five countries, one decade: the credibility test ahead

The programme’s distinctiveness is genuine. A five-country footprint, a stated €10 billion first series, state-backed partners including Edison, and a link to Italy’s historic nuclear re-entry give this more substance than most SMR proposals reach at this stage.

What stays open is not background noise. Senate ratification in Italy, the creation of a functioning safety regulator, and site confirmations in three further countries are live variables, and the NuScale cancellation is a reminder of how such programmes can unravel. The first decisive test arrives before 2029, when Nuward’s commercialisation milestone will show whether the map, the figure, and the deadline are turning concrete or staying on paper.
