When Israeli aircraft recently struck a uranium-enrichment complex in the nation, Iran could have been days away from ...

When most people hear the word uranium, they think of mushroom clouds, Cold War standoffs or the glowing green rods from ...

Uranium-235 is essential for nuclear reactors and weapons, and for that, enrichment is necessary. The process starts by converting uranium ore into uranium hexafluoride (UF6) gas.

There are other uses of uranium apart from nuclear weapons as discussed in this article. Uranium is a silver-grey metal that is radioactive. The most common types are uranium 235 and uranium 238. The ...

Uranium enriched to 4.5% is 4.5% uranium-235. And so on. So does Iran's breaking of its enrichment threshold mean that the country is now significantly closer to having a bomb?

It’s naturally radioactive, but its isotope uranium-235 also happens to be fissile, as Nazi nuclear chemists learned in 1938, when they did the impossible and split a uranium nucleus in two.

One kilogram of Uranium-235 if led through complete fission is equivalent to the chemical energy that can be extracted by burning 1.5 million kilograms of coal.

When arms control experts talk about uranium enrichment, they're referring to the percentage level of U-235. The goal is to remove unwanted U-238 isotopes from the uranium and increase the ...

Four years ago, Iran began enriching uranium on an industrial scale with centrifuges, machines that spin extraordinarily fast to separate uranium 235 from the more common form of the element ...

U-235 makes up a very small portion of uranium ore. It must be extracted through an enrichment process that leaves the remainder of the ore behind. This remainder is known as depleted uranium.

When uranium-235 decays naturally, one of its byproducts is a free neutron, which is why it could spur the reaction in the ore deposit. For a nuclear reaction to be self-sustaining, ...
