Commercial nuclear reactors all work pretty much the same way. Atoms of a radioactive material split, emitting neutrons.

The biggest nuclear power plant in the United States is not a single hulking reactor, but a sprawling complex whose scale is measured in gigawatts and square miles. Its turbines quietly push out ...

An innovative algorithm for detecting collisions of high-speed particles within nuclear fusion reactors has been developed, inspired by technologies used to determine whether bullets hit targets in ...

Piece by piece, bolt by bolt, the Indian Point nuclear power plant is being stripped down to its parts, each one a snapshot in time from the plant’s six decades supplying electricity to New York City ...

Preliminary testing has taken place of an ultrasound system which is designed to provide an additional picture of the BN-800 fast neutron reactor core at Beloyarsk Nuclear Power Plant. Beloyarsk unit ...

OAK RIDGE, Tenn. (AP) — Near signs that warn of radioactive risk at Oak Ridge National Laboratory, a half-dozen workers from the nuclear power company X-energy are making what appear to be gray ...

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 ...

The interiors of fusion reactors can get seriously chaotic. But for obvious reasons—like extreme temperatures and pressures—researchers aren’t typically able to peek directly inside a reactor. Some ...
