HEXANA is a deep-tech energy startup focused on designing and commercializing a fourth-generation SMR that uses a sodium-cooled fast-neutron reactor core. By coupling the reactor with a closed fuel-cycle approach, the company aims to maximize fuel efficiency and minimize nuclear waste. Its technology targets heavy industrial sectors that remain significant CO₂ emitters, offering a path to large-scale decarbonization while reinforcing energy sovereignty. The reactor is positioned as an ultra-low-carbon power solution, addressing both climate and strategic supply concerns. HEXANA’s team has attracted strong confidence from investors and partners, as evidenced by its recent multimillion-euro financing. Although specific operating metrics such as revenue or deployment timelines were not disclosed, the sizeable capital raise underscores market interest in advanced nuclear innovation. Future plans include continued reactor development and progression toward commercial deployment, backed by staged funding commitments extending through 2026.
