Newcleo is a Franco-Italian nuclear developer building lead-cooled fast reactors (LFRs) that use reprocessed nuclear waste as fuel. The company raised €75 million in early 2026 (its €88M article round) bringing 2025 fundraising to over €124 million and total funding to likely more than €645 million. Newcleo operates in France, Italy, the UK, Belgium, and Slovakia with approximately 1,000 employees. The design reduces long-term waste storage needs while generating clean power. The company completed the ASNR preparatory review in 2025 and is pursuing UK ONR justification simultaneously.
