X-energy’s Xe-100 Gen IV reactor uses TRISO fuel and helium cooling to deliver meltdown-resistant, modular nuclear power.

At the same time, a current of cold electrons travels toward the heated plasma from the opposite direction. When the two meet, the plasma develops filament-shaped instabilities that SLAC’s facilities ...

The coming decades of space exploration hinge on a single, stubborn number: the 225 million kilometres between Earth and Mars. Chemical rockets, the workhorses of every space programme to date, take ...

The U.S. Nuclear Regulatory Commission has advanced a key step toward a new special nuclear material license for fuel fabrication: publishing the Final Environmental Impact Statement for TRISO-X, ...

China breaks a historic barrier in nuclear fusion, bringing the dream of nearly infinite energy closer to reality.

Most nuclear energy is thermal. All that complex nuclear physics and chemistry serve merely to create steam that spins a ...

A mathematical equivalent of a microscope with variable resolution has shed light on why some atoms are exceptionally stable, a riddle that has persisted in nuclear physics for decades ...

Muons tend to scatter more from high-atomic-number materials, so the technique is particularly sensitive to the presence of materials such as uranium. As a result, it has been used to create systems ...

The incident, about seven miles from the Thule Air Force base, “released trillions of respirable particles of weapons grade ...

The NRC has approved TRISO-X to produce advanced HALEU fuel, marking the first new US nuclear fuel license in decades. The US Nuclear Regulatory Commission has approved a new license that allows TRISO ...

In a milestone for the U.S. nuclear fuel cycle, the Nuclear Regulatory Commission (NRC) on Feb. 13 issued its first approval of a commercial Category II ...

Before the RHIC shut down, it was the only operational particle collider in the U.S. and one of two heavy-ion colliders in the world, the other being the Large Hadron Collider at CERN in Switzerland.
