Summary
Oklo’s Groves Isotope Test Reactor in Texas reached criticality, meaning its nuclear chain reaction became self-sustaining enough to produce a steady release of energy.
The Energy Department said the reactor is the fifth to hit that milestone under a pilot program designed to speed development of advanced nuclear technology and prove it can work.
Oklo shares rose 4.3% to $44.86 in premarket trading after the announcement, though no small modular reactors are yet operating commercially in the US.
The milestone aligns with the White House push to expand nuclear power, with Donald Trump targeting 10 large reactors under construction by 2030 and 400 gigawatts of US nuclear capacity.
