FLARE is SHINE Technologies' accelerator-driven D-T fusion neutron system, producing up to 50 trillion neutrons per second for radiation-effects testing; it has served government and industry customers since August 2023. SHINE, which raised a $240 million Series E in 2026 (over $1 billion total), treats fusion power as a long-term goal after isotopes and waste recycling.
