Nuclear startup Radiant just raised another $300M to build a reactor small enough to fit on a semi-truck. (TechCrunch)
This fundraise values the company at $1.8B and caps a wild month for the sector as investors bet that mass-manufactured fission is the best way to power the AI boom.
Radiant’s 1 MW microreactor is designed to replace diesel generators at remote sites or data centers. It uses meltdown-resistant TRISO fuel and runs for 5 years before the entire unit is simply hauled away for refueling.
The company is racing to test its demo unit at Idaho National Lab by next summer, aiming to be one of the first to hit the Trump administration’s July 4 criticality target.
