As the spallation neutron beam passes through the TRISO particle, some neutrons are absorbed by the uranium while most are scattered away. A neutron area detector collects the scattered neutrons, ...

An international team of scientists has identified an unexpected region of heavy, neutron-deficient isotopes in the nuclear chart where nuclear fission is predominantly governed by an asymmetric mode.

Building on past use of nuclear systems, NASA and the Department of Energy are developing small nuclear fission reactors for the Moon to provide reliable, long-duration power for future Artemis missio ...

Scientists at the University of British Columbia (UBC) have made a breakthrough that could help bring nuclear fusion — often described as the "holy grail" of clean energy — out of giant research ...

US researchers have quietly crossed a threshold in nuclear materials science, using intense neutron beams to peer inside ...

NASA wants to build a nuclear reactor on the surface of the moon—and fast. Transportation Secretary Sean Duffy, who is also serving as NASA’s interim administrator, has issued new directives at the ...

A five-dimensional model accurately predicts the asymmetric fission of mercury isotopes, advancing our understanding of nuclear fission beyond traditional heavy elements such as uranium and plutonium ...

Last week, Deep Fission broke ground on a pilot program to bury small modular reactors underground in Parsons, Kansas. This project is the first of its kind in the United States, and comes as part of ...

The U.S. and China lead global efforts to make nuclear fusion commercially viable, with billion-dollar projects aiming for net-positive energy. Los Alamos scientists successfully recreated a 1938 ...

Nuclear and plasma physics form complementary pillars in our understanding of the fundamental forces and states of matter. Nuclear physics investigates the structure, dynamics and interactions of ...
