The US Department of Energy approved the Documented Safety Analysis for Radiant's Kaleidos microreactor, authorizing the unit for full-power operation. ZeroHedge reported that this milestone allows the 1-megawatt microreactor to transition from zero-power criticality tests to full operational testing at the Idaho National Laboratory.
This regulatory progress comes as shares of small modular reactor companies, including Oklo and NuScale, have crashed to multi-year lows. Despite the technical advancement achieved by Radiant, market sentiment remains bearish on the broader sector as related clean tech equities continue to face significant downward pressure.
