A persistent asymmetry in fusion exhaust has challenged researchers for years. New simulations show that plasma core rotation, working together with cross-field drifts, determines where particles land ...

The liquid-fueled molten salt reactors such as the MSRE and the TMSR-LF have distinguishing dynamic features compared with solid-fueled reactors, such that conventional system analysis codes are not ...

Oak Ridge National Laboratory (ORNL) reports it has tested a high-temperature fission chamber prototype built by ...

Scientists in the US have developed a new glowing surrogate nuclear reactor that replaces ...

Fusion energy promises a future of clean, nearly limitless power, but building reactors that can survive the extreme ...

The PROSPECT-I detector in operation at Oak Ridge National Laboratory’s High Flux Isotope Reactor. Designed to be as close to the reactor core as possible, this unique instrument performed precise ...

In the traditional two-step method, the homogenization group constants of the fuel assembly are calculated using the assumption of reflective boundary conditions. In the hybrid two-step method used in ...

The race to recreate the sun’s power on Earth just hit a major milestone. Scientists operating a powerful fusion reactor, often nicknamed China’s “artificial sun,” set a world record that’s turning ...

Nuclear reactions as a research area encompass the experimental and theoretical study of processes in which atomic nuclei interact and transform, including fusion, fission, scattering, and transfer ...

Researchers at the DIII-D National Fusion Facility have identified a new method to tame ...
