⚛️📽️ In 1961 the US Atomic Energy Commission installed the world's first nuclear-powered weather station 700 miles from the North Pole. 17,500 curies of Strontium-90 powered a broadcast of the arctic weather every 3 hours. "A free contribution to the world community."

The Antares design transfers heat from the primary coolant heat pipes to a closed nitrogen Brayton power cycle. It's cool to see the turbine!

When TRISO fuel was first invented in 1961, it was intended to be used in Uranium-Thorium breeder high-temperature gas-cooled reactors to avoid the non-economical long-term costs of HALEU. Lots of early HTGRs had thorium breeding pebbles (Dragon, THTR-300, AVR, Peach Bottom, Ft. St. Vrain). You absolutely can reprocess TRISO fuel. You just burn the carbon layers off.
Full as-designed power operation on this timeline is LEGIT. Excited for startup!
Radiant has secured U.S. Department of Energy (@ENERGY) approval of its Documented Safety Analysis for Kaleidos, making it the only microreactor to be reviewed and approved by the DOE for full power operations.
The approval is not just for criticality, but for Radiant’s full power, full temperature testing at the Idaho National Laboratory. Radiant will test the complete reactor system using the same design it will manufacture at scale.
Next up in the path to commercialization: Readiness Review.
