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 ...

A five-dimensional (5D) Langevin approach developed by an international team of researchers, including members from Science Tokyo, accurately reproduces complex fission fragment distributions and ...

While international diplomacy remains hyper-focused on Iran’s uranium enrichment, a massive stockpile of plutonium sits ...

China is building two advanced nuclear reactors with Russian assistance that will produce plutonium for Beijing’s rapid buildup of nuclear weapons, according to a new Air Force think tank study. The ...

A new nuclear reactor design skips fuel entirely—eliminating meltdown risk while testing a safer future for nuclear power. Here’s how it works.

Here’s how a nuclear bomb actually works. The B61 and the B83 nuclear bombs currently in the United States’ arsenal are thermonuclear, or hydrogen bombs, and quite different than the fission weapons ...

Repurposing surplus plutonium as reactor fuel could cut costs, ease the advanced nuclear fuel bottleneck, and offer a more permanent nonproliferation solution than dilute and dispose. America has some ...
