In a major step forward for nuclear safety, General Atomics Electromagnetic Systems (GA-EMS) has announced the successful completion of a 120-day irradiation testing period for its innovative SiGA ...

Fireplaces are cozy until it’s time to shovel out the ashes. Nuclear power has the same problem: abundant, reliable energy ...

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

Outdone only by nuclear fusion, the process of nuclear fission releases enormous amounts of energy. The ‘spicy rocks’ that are at the core of both natural and artificial fission reactors are generally ...

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 vision of a U.S. nuclear power renaissance has a blind spot—uranium fuel—in the near term and long, according to a ...

Scientists have built the first-ever thorium reactor. Thorium is both more easily accessible and less dangerous than uranium—the most common fission fuel. The system also uses molten salt instead of ...

A new nuclear fuel plant rising in Tennessee is turning a once-esoteric technology into a cornerstone of the energy ...

At the intersection of mathematics and nature, scientists have found intriguing and often beautiful designs. Pinecone scales ...
