Newcleo, a pioneer in advanced modular reactor (AMR) technology and nuclear fuel manufacturing, has achieved a significant regulatory milestone for its planned mixed-oxide (MOX) fuel facility in France. The French Nuclear Safety and Radiation Protection Authority (ASNR) published its opinion on July 13, 2026, concluding that the safety provisions proposed by the company are satisfactory at this stage. This development marks a critical step in Newcleo's efforts to establish a first-of-a-kind MOX fuel manufacturing facility in the country.

ASNR Safety Opinion

The ASNR reviewed the safety approach dossier submitted by Newcleo in December 2024. The regulator concluded that the provisions proposed for the facility’s safety demonstrations are capable of meeting the objectives established under the applicable French nuclear safety framework. While the opinion identifies areas for further development, Newcleo intends to incorporate these recommendations into the facility design to support a future construction license application.

France 2030 Program Transition

Following an evaluation of Newcleo's application for Phase 2 of the France 2030 innovative reactor program, the General Secretariat for Investments (SGPI) determined that the company has surpassed the program's scope. Since joining the program, Newcleo has raised a significant amount of capital and achieved a substantial international presence. On May 27, 2026, the company entered into a definitive agreement for a business combination with NewHold Investment Corp. III (NASDAQ: NHIC), valuing Newcleo at a pre-money equity value of approximately $2.4 billion.

Future Collaboration

As a result of these developments, the French State will continue working with Newcleo through alternative forms of cooperation. This includes licensing support with the ASNR, engagement with state services regarding proposed projects in France, and export-facing initiatives. The company is also progressing through a similar regulatory process for its Lead-Cooled Fast Reactor (LFR) design and is currently awaiting the ASNR's opinion on its proposed safety features.

Stakeholder Engagement

In parallel with regulatory advancements, Newcleo is conducting a three-month public debate on its proposed French LFR and MOX fuel facility projects. This initiative makes Newcleo the first private developer of an innovative reactor technology to complete this key stage of stakeholder engagement in France. The company will assess the conclusions of the National Commission for the Public Debate to refine its ongoing development and planning.

Newcleo has entered into an agreement to acquire Bonifait Pesage, a French manufacturer of nuclear-grade scales and precision industrial weighing equipment. The transaction will expand Newcleo's presence in the French nuclear ecosystem, leveraging Bonifait Pesage's established customer base. Financial terms of the acquisition were not disclosed.

Strategic Rationale

The acquisition aligns with Newcleo's focus on advanced modular reactor (AMR) technology and nuclear fuel manufacturing. By integrating Bonifait Pesage, the company aims to enhance its capabilities in precision equipment critical for nuclear operations.
