Hydrogen bombs and atomic bombs are both nuclear weapons that can cause mass destruction. Most US nuclear weapons today were made in the 1950s and 1960s and are H-bombs. H-bombs are more powerful, ...

Nuclear bombs do not rely on size, they rely on physics. Here is how chain reactions and hydrogen bombs unleash power on a city-ending scale.

This article is part of “The New Nuclear Age,” a special report on a $1.5-trillion effort to remake the American nuclear arsenal. In early nuclear bombs, like the ones the U.S. dropped on Japan in ...

Instead of burying plutonium and pretending it has disappeared, we can put it to work. With advanced fast reactors, like those being developed by private American innovators, stored fuel will be ...

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 ...

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 ...

Experts called it the biggest atomic news since the end of World War II. The Atomic Energy Commission revealed last week that it is now considered practical to build a nuclear reactor which will ...

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 ...

Buried deep in the desert near the plutonium plant at Hanford, Wash. are thick-walled concrete treasure chests, guarded by a stronger curse than watches over any Egyptian tomb. If a thief were to try ...
