**<br> NucNet Interview: As Nasdaq Listing Approaches, France's Newcleo Says US Most Likely Location For First Commercial Reactor**

NucNet

Written by Nigel Davies

Europe's nuclear programme 'not strong enough', says company's chief executive Stefano Buono.

The first commercial reactor from France-based Newcleo will probably be deployed in the US thanks to overwhelming investment in innovation and a supportive policy backdrop, the chief executive of the advanced reactor manufacturer told NucNet in an interview.

Speaking on the sidelines of the European Bank for Reconstruction and Development (EBRD) annual conference in Riga, Newcleo chief executive officer Stefano Buono was optimistic about the company's prospects in the US following its recently announced plans for a Nasdaq listing and partnership with Sam Altman-backed nuclear technology company Oklo.

Buono said that Newcleo's listing on the technology heavy stock index should fund the company's work for the next two years. Such a supportive entry to the US, as well as a strong nuclear policy framework, could well see the company's first reactor land on US shores.

Newcleo is designing a 200 MW commercial lead-cooled fast reactor aimed at supplying electricity and heat to industrial complexes, data centers and other energy intensive industries.

**"**We have a few candidates for our first commercial reactor, but the accelerated environment in the US could make it possible to do the first reactor there," said Buono.

"We have launched projects in France and Slovakia too, so timing will be defined on how fast we can implement our programmes. But it looks like the US is a very good candidate thanks to Part 53 and the strong support we have from the government there," added Buono.

Part 53 refers to the Nuclear Regulatory Commission's (NRC) framework supporting the development of advanced reactors in the country.

Buono's belief in the benefits of advancing strongly in the US chime with Swedish peer Blykalla, whose chief executive officer also eyes strong growth in the country.

**European Nuclear Programme 'Not Strong Enough'**

Buono said he did not think there was a strong enough nuclear programme implemented in Europe at the moment, and for that reason did not see any political pressure to have its first reactor in the continent first.

"There is a willingness to restart nuclear in Europe after a sort of dark age. But we need to see a global public acceptance for nuclear across Europe. We have just seen a move in Italy for example to pass a legislation on nuclear."

Buono said he measured the true acceleration of nuclear by the means of investment on a private and public level.

"The money is not yet there at a political level in Europe. That would be the sign of a true acceleration."

He said that even under the former Joe Biden administration in the US that three advanced reactor companies had received $4.1bn (€3.5bn) in subsidies.

"So, the EU's €200 million guarantee fund is a good start, but it's just a start." The European Commission said recently it will create the €200m fund to support private investment, as detailed in the EU Strategy for small modular reactors, adopted on 10 March 2026.

Buono said the Scaleup Europe Fund of €5bn could help advance nuclear. "This is money that could potentially be deployed in nuclear innovation, but the budget is still blocked in Europe and there are still some countries that are against nuclear."<br>

The Scaleup Europe Fund is designed to fund late-stage European technology companies and prevent promising startups from fleeing to the US or Asia.

**Infrastructure Funds Show Interest**

Buono pointed to recent interest in Newcleo from infrastructure funds as a potential new source of investment into advanced reactors.

"We are not yet enjoying the moment where nuclear is heavily financed in Europe, but we are seeing the first signs," said Buono.

"For the first time we are interacting with infrastructure funds on our potential products. So, infrastructure funds start to be attracted by nuclear because they are long-term investors."

Similarly, he said that nuclear had come back onto the horizon of institutions including the EBRD, World Bank, and European Investment Bank, which helped build momentum.

He said it was yet to be seen how an SMR could be de-risked by government support to spur interest from infrastructure investors.

"Later, when SMRs are perceived not as a risky investment, but more as an infrastructure necessity, I am sure these types of funds will be more and more involved in the financing."

In terms of demand, he said right now there was overwhelming interest in SMRs which could not be met by the market, and he expected that situation to last for one or two decades to come.

**A Nasdaq Boost?**

Buono said that before the company's planned listing on the Nasdaq it had raised around $780m from mostly European investors to fund its development, and now its stock-market entry would open it up to new investors.

"Europe is not a rich market when it comes to investing in innovation. The US market is much more devoted to innovation, so for us it gives the possibility to address a new market," said Buono.

He said many US funds had committed capital to the transaction and this left them in a well-funded position for some time.

"If there are no redemptions, we will not need additional cash for more than a couple of years, even if we accelerate in our capital deployment, so we are happy with the result."

**Fuel Advances And Oklo Tie Up**

Buono said the company continued to work in its partnership with Oklo signed in October 2025 to advance in negotiations with the US Department of Energy's (DOE) surplus plutonium utilisation programme.

The two companies plan to develop an advanced fuel fabrication facility in the US, which Buono says has the target to be operational by 2031, or before if the process can be accelerated with the NRC. An announcement on deployment might be expected this year, he said.

He said the facility would produce several types of fuels for advanced reactors, including the mixed-oxide (MOX) fuel needed for its reactors.

"We need capacity that can generate significant amounts of fuel for the next years for our needs, but also for the potential needs of our partners."

Buono said the company planned three different MOX producing facilities, with one also planned in France set to be operational by 2032. Newcleo is working with France and through a partnership with Slovakia's state-owned Javys to be able to obtain the plutonium required to manufacture its fuel.

Buono said that all these facilities could then deliver fuel to other reactor operators worldwide.

"We want to be an actor in the market, and partner with those countries that can build reactors multiple times."

Newcleo is progressing on the installation of its non-nuclear test facility at the Brasimone research centre in Italy, which Buono said had now received the main vessel for molten lead conditioning and storage.

The reactor demonstration facility would produce around 10 MW of thermal power, and the CEO said it was on target to be finished by the end of 2026, with commissioning in 2027.

He said they would be then able to simulate the industrial set-up of a reactor, in both start up and shut down conditions, and also simulate an incident such as a blocked pump.

**France Plans Edge Closer**

Buono said work was advancing over safety permits with the French Nuclear Safety and Radiation Protection Authority (ASNR) before a potential reactor construction application in 2027.

He said at present there was an open public debate before the filing of a construction permit. A final strategy would be given after this debate was concluded in July.

"We will decide on the timing of the permit this year, but I think we will file the request next year."

"The Slovakian government is really supportive of this project," he said.
