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.

NASA and the Department of Energy signed an agreement earlier this week committing to put a nuclear reactor on the moon in 2030, the same

NASA commits to nuclear reactor on the moon by 2030 after Trump admin pushed for expedited timeline - The reactor would be a major tool for future moon and Mars missions

Southern Company's Plant Vogtle nuclear power complex made history in 2023 by bringing the first new U.S. nuclear reactor built from scratch in the past 30 years online, according to a Fortune report. The Georgia facility soon opened a second reactor ...

Theoretically, there's no better, more practical source of reliable, carbon-free energy than the current generation of nuclear reactors. In practice, the theory holds water, but there are still a few glaring issues. Suspect number one? That'd be the ...

A company with a vision of installing “discreet, bespoke,” small, nuclear reactors 1 mile underground for data centers and other electricity-hungry industries plans to put its first reactors in Kansas, Texas and Utah. Deep Fission, which says its ...

NASA and the Department of Energy have officially embarked on an ambitious goal to plant a nuclear reactor on the Moon's surface by 2030. When completed, it will have enough output to power multiple lunar households for up to 10 years.
