Not that anyone asked, but uranium enrichment is certainly a newsworthy topic where a little science might be helpful. Here's ...

The difference between uranium-238 and uranium-235 When we dig uranium out of the ground, 99.27% of it is uranium-238, which has 92 protons and 146 neutrons. Only 0.72% of it is uranium-235 with 92 ...

The difference between uranium-238 and uranium-235 When uranium is mined from the earth, almost all of it—about 99.27%—is a type called uranium-238, which has 92 protons and 146 neutrons.

Centrifuges exploit the fact that uranium-238 is about 1% heavier than uranium-235. They take uranium (in gas form) and at 50,000 to 70,000 rotations per minute, with the outer walls of the ...

Centrifuges exploit the fact that uranium-238 is about 1 per cent heavier than uranium-235. They take uranium (in gas form) and use rotors to spin it at 50,000 to 70,000 rotations per minute, with the ...

The real debate has never been about what to do with Iran’s nuclear program. It’s always been about what to do with the ...

Most nuclear reactors need fuel containing between 3.5% and 5% U-235 - known as low-enriched uranium, or LEU. Advanced reactor designs that are now being developed - and many small modular reactors - ...

When Israeli aircraft recently struck a uranium-enrichment complex in the nation, Iran could have been days away from achieving “breakout,” the ability to quickly turn “yellowcake” uranium ...

Natural uranium is mostly uranium‑238 – about 99.3%, which isn’t good for power or bombs. Only about 0.7% is uranium‑235, the part needed to release energy.
