Newcleo SA

Newcleo SA is a European nuclear energy company dedicated to developing advanced nuclear technologies. Its core mission is to generate safe, clean, and sustainable nuclear energy by enabling a circular nuclear economy through the closing of the nuclear fuel cycle. The company's headquarters are located in Paris, France, following a strategic relocation from London in late 2024 to enhance European partnerships and access institutional funding opportunities.

Newcleo specializes in the design, construction, and operation of Generation IV lead-cooled fast reactors (LFRs) and small modular reactors (SMRs). These advanced reactors are engineered to utilize recycled nuclear waste, specifically Mixed Oxide (MOX) fuel, thereby reducing the volume of long-lived radioactive waste and improving fuel efficiency. The company's technology aims to provide low-carbon, baseload power solutions for utilities, industrial energy users, and governments, addressing global demands for decarbonization and energy security.

Under the leadership of founder, CEO, and Chairman Stefano Buono, Newcleo has secured substantial private funding, exceeding €570 million as of late 2024. The company is progressing with ambitious development timelines, which include a precursor reactor in Italy by 2026, a MOX manufacturing plant in France by 2030, and a prototype 30 MWe LFR in France by 2031, with commercial reactor deployment anticipated from 2033. Newcleo has also commenced pre-application engagement with the U.S. Nuclear Regulatory Commission for its advanced reactor and fuel fabrication facility.
