Fireplaces are cozy until it’s time to shovel out the ashes. Nuclear power has the same problem: abundant, reliable energy paired with a growing pile of difficult-to-discard spent fuel. But a new reactor design aims to “burn” part of that nuclear ash by turning certain spent fuel back into usable energy.

Commercial nuclear reactors all work pretty much the same way. Atoms of a radioactive material split, emitting neutrons. Those bump into other atoms, splitting them and causing them to emit more neutrons, which bump into other atoms, continuing the chain reaction.

In a bold, strategic move for the U.S., acting NASA Administrator Sean Duffy announced plans on Aug. 5, 2025, to build a nuclear fission reactor for deployment on the lunar surface in 2030. Doing so would allow the United States to gain a foothold on the ...

Researchers have employed Bayesian neural network approaches to evaluate the distributions of independent and cumulative fission yields for neutron-induced ²³²Th fission, while also elucidating energy-dependent yield variations for selected nuclides.

PARSONS, Kan. (WIBW) — A groundbreaking ceremony is set for next week on an underground nuclear reactor in southeast Kansas, officials said. Deep Fission Inc., based in Berkeley, California, announced Thursday that it has selected the Great Plains ...

PARSONS, Kan. — A California company has announced plans to bring a first-of-its-kind nuclear reactor to Southeast Kansas that it hopes will be generating electrical power in the next two or three years. Deep Fission’s plans include placing a small ...
