Late last week, Israel targeted three of Iran’s key nuclear facilities – Natanz, Isfahan and Fordow, killing several Iranian nuclear scientists. The facilities are heavily fortified and largely ...

A California-based lab has made the first experimental measurements of nuclear reactions in high-energy-density ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study provides new ...

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

Nuclear astrophysics is dedicated to unravelling the complex nuclear processes that govern stellar evolution, explosive cosmic events and the synthesis of elements throughout the Universe. Central to ...

LEU fuels are essentially a uranium ceramic, but highly enriched fuels are a uranium-zirconium or uranium-aluminum alloy. They also incorporate what are called burnable "nuclear poisons," which are ...

The Idaho National Laboratory (INL) has cleared a major hurdle in making a Generation IV nuclear reactor practical. Using a new process, a team has developed a new way of processing fuel efficiently ...

GREIFSWALD, GERMANY - OCTOBER 29: A worker explains a photo taken about a year and a half ago that shows construction of the interior plasma chamber of the Wendelstein 7-X experimental fusion reactor ...

Robert Zubrin’s Nuclear Salt Water Rocket (NSWR) design is a rocket that uses known physics and engineering . There are versions that could reach 7-8% of light speed. The use of low grade uranium ...
