Industrial Giants Fuel Newcleo's Advanced Nuclear Ambitions

PARIS, France – February 04, 2026 – European advanced nuclear developer newcleo has secured over USD 125 million in new financing over the past year, signaling a powerful vote of confidence not just from venture capital, but from the heart of heavy industry. The funding, which includes a recent USD 85 million round, brings the company's total capital raised since its 2021 launch to more than USD 755 million, fueling an aggressive expansion aimed at turning nuclear waste into a clean energy source for the world's most energy-intensive sectors.

The latest financing round is notable for the strategic players it brings to the table. Alongside continued support from early backers like Kairos, Azimut Investments, and the CERN pension fund, newcleo has attracted capital from industrial powerhouses including steel manufacturer Danieli & C., cement producer Cementir Holding, and valve maker Orion Valves. This influx of "smart money" from future end-users underscores a pivotal shift in the energy transition: the recognition that advanced nuclear power may be the key to decarbonizing industries that have long been considered the hardest to abate.

A Billion-Dollar Bet on Industrial Decarbonization

The participation of major industrial firms is more than a financial transaction; it's a strategic endorsement of newcleo's technology as a viable solution for achieving net-zero emissions. For sectors like steel and cement, which require immense amounts of constant, high-temperature heat and electricity, intermittent renewable sources like wind and solar present significant challenges. Advanced Modular Reactors (AMRs), like the lead-cooled fast reactors (LFRs) newcleo is developing, promise to deliver this kind of reliable, carbon-free power on a smaller, more adaptable scale than traditional nuclear plants.

"Our ability to deliver impactful low-carbon energy solutions for energy-intensive firms is proving an attractive investment rationale for both industrial and financial investors," said newcleo CEO Stefano Buono in a statement. He noted that the company's "tangible progress" is a key differentiator in the race to deliver next-generation nuclear energy.

The investments are cementing formal collaborations. Danieli, for example, had previously signed an agreement to explore integrating newcleo's reactors with its steelmaking processes to create "green steel." Similarly, Cementir's investment follows a pact to study synergies with the Italian cement industry. This trend suggests a move towards creating localized, self-contained clean energy ecosystems where reactors directly power the factories that are investing in them.

Turning Nuclear Waste into a Clean Energy Asset

At the core of newcleo's appeal is its innovative approach to the entire nuclear fuel cycle. The company's LFRs are designed to run on Mixed Oxide (MOX) fuel, which is fabricated from reprocessed nuclear waste—specifically, the plutonium and depleted uranium left over from conventional reactors. This "waste-to-energy" model tackles two of the nuclear industry's most persistent challenges simultaneously: energy production and long-term waste management.

By burning these long-lived radioactive elements, the technology can extract significantly more energy from the original uranium ore while drastically reducing the volume and radiotoxicity of the final waste. Proponents claim the residual waste would decay to the level of natural uranium in a few hundred years, as opposed to hundreds of thousands of years for conventional spent fuel.

This technology also boasts significant safety advantages. The reactors operate at atmospheric pressure, eliminating the risk of a high-pressure coolant leak. The molten lead coolant has a very high boiling point (over 1700°C), providing a massive safety margin, and is chemically inert, meaning it won't react violently with air or water as sodium can in other fast reactor designs.

To realize this vision, newcleo is pursuing a strategy of vertical integration. The company has submitted a nuclear safety program in France and secured a site in Nogent-sur-Seine with plans to build its own advanced fuel manufacturing facility, aiming to apply for a construction license by the end of 2027.

From Europe to America: The Global Race for Next-Gen Nuclear

Armed with fresh capital, newcleo is accelerating its international expansion, positioning itself as a key player in a global race for energy independence and technological supremacy. While founded in the UK, the company has pivoted its focus to mainland Europe and the United States, citing a more favorable policy environment for its closed fuel-cycle technology.

In France, which is heavily reliant on nuclear power, newcleo is deep into the pre-licensing process with the nuclear safety authority. It has initiated the land acquisition process for a site in Chinon to deploy its first advanced reactor, complementing its fuel plant project.

In Italy, the company is establishing a major R&D hub. At the ENEA Brasimone Research Center, construction is underway for PRECURSOR, a 10 MW non-nuclear replica of its reactor. This facility, slated for completion by the end of 2026, will be a unique testbed for qualifying all reactor components and systems in an integrated fashion before any nuclear material is involved.

Further east, a joint venture with Slovakia's state-owned nuclear company JAVYS aims to deploy up to four 200 MWe reactors at an existing nuclear site, demonstrating a path to replace or supplement aging power infrastructure.

The company's most recent strategic push is into the United States. Buono described the US as "the most dynamic market for advanced reactor technologies," and newcleo has already forged a strategic partnership with American developer Oklo. The collaboration aims to co-develop a domestic supply chain for advanced nuclear fuel, a critical step for deploying next-generation reactors on US soil.

The Road Ahead: Milestones, Hurdles, and a Crowded Field

Despite the momentum and significant funding, the path from blueprint to a fully operational power plant is long and fraught with challenges. The company's timelines are ambitious, with plans to apply for major construction licenses in France within four years. Navigating the complex, multi-stage regulatory processes for a novel reactor design in multiple countries will be a formidable task requiring immense technical and legal resources.

Furthermore, newcleo is not operating in a vacuum. The advanced nuclear space is becoming increasingly competitive, with well-funded rivals like Bill Gates-backed TerraPower and US-based X-energy also making significant strides. TerraPower's Natrium reactor is moving forward in Wyoming, while Oklo recently received the first site use permit for an advanced reactor from the U.S. Department of Energy.

However, newcleo's strategy, guided by physicist-entrepreneur Stefano Buono—who previously built and sold a nuclear medicine company to Novartis for nearly USD 4 billion—is what sets it apart for its investors. Its focus on vertical integration, a proven technology platform, and a solution that addresses the entire fuel cycle gives it a distinct position in the quest to power the next industrial revolution with clean, reliable, and sustainable nuclear energy.
