    Full Analysis

    Several nuclear microreactor startups raised venture funding in 2020-2023, promising clean energy from small modular reactors. But nuclear regulatory approval takes 10-15 years minimum — far longer than the 5-7 year VC return cycle. Multiple startups in this space burned through their funding before achieving regulatory milestones. The technology may be viable but the funding model was wrong.
