The headlines make the Three Mile Island restart sound like flipping a switch. It isn’t. Unit 1 has sat cold and dark since 2019, and waking it means reversing years of coolant chemistry gone wrong — and proving that steel damaged by decades of neutrons still holds enough margin.
On the afternoon of June 04, 2026, in a test building at Idaho National Laboratory, a small machine called Mark-0 reactor did something no privately built reactor of its kind had done on American soil in over forty years: it came alive. Mark-0 was built by a California startup named Antares Nuclear that didn’t exist…
Big Tech has bet ~9.8 GW of nuclear on AI. But can SMRs actually power AI data centers in time — or is something else keeping the lights on right now?
Most advanced reactors need HALEU to run — and the West can barely make any. What this fuel is, why it matters, and the supply gap holding nuclear back.
Microsoft restarted Three Mile Island for AI. Behind that deal stands the small modular reactor — the nuclear revolution that keeps being five years away.
A dying Wyoming coal town, a Bill Gates reactor, and Meta’s AI data centers — the story of Natrium, the reactor that works like a giant battery.
The first reactor to make electricity was a fast reactor. Seventy years later it’s still called the reactor of the future — but in 2026, that finally started to change.
A reactor engineer separates fact from fear — debunking the seven most stubborn nuclear safety myths, from Chernobyl and Fukushima to waste and radiation, using the data the headlines never show.
Every reactor is deliberately fed a “poison” — boron. A reactor engineer explains what neutron poison is, why boron is essential, and how it keeps a reactor under control.
