Portable Microreactors Shift Nuclear Complexity From Customers to Manufacturers
Radiant argues that nuclear power can become easier to deploy if reactors are built and sold as transportable products rather than bespoke, permanent construction projects. Tori Shivanandan and Doug Bernauer say the company’s Kaleidos microreactor would deliver roughly five years of power, then return to Radiant for refueling and waste-related obligations, leaving customers without a long-term nuclear site. A planned full-power test at Idaho National Laboratory is meant to show whether that factory-built model can work in practice.
