All of the uranium in the bomb dropped on Hiroshima was enriched in Oak Ridge, including at the K-25 gaseous diffusion plant, ...

Low-enriched uranium is composed of around 5% uranium-235, the fissile isotope that splits to power nuclear reactors. In the long term, the government will need more highly enriched uranium, also ...

A single kilogram of uranium-235 (the most popular fissile isotope of uranium) can theoretically produce the same amount of power as 1.5 million kilograms of coal. Nuclear fission also doesn’t ...

These documents include its having been logged in the boat’s manifest (and besides an eyewitness account of it having been labeled “U-235," the correct isotope of enriched uranium).

Heisenberg noted that they could use pure uranium 235, a rare isotope, as an explosive. In the summer of 1940, Carl Friedrich von Weizsäcker, a younger colleague and friend of Heisenberg's ...

Molten Salt Reactors (MSRs) are nuclear fission reactors in which either the fuel and/or the coolant is a molten salt. Molten salt is salt which liquifies at elevated temperatures and can store ...

It either must be enriched—made more concentrated in a rare form of uranium (U-235)—or converted into plutonium (Pu-239). Heavy water can play a role in breeding weapons-grade plutonium from ...

Iran’s 60% level enriched uranium had increased to 275 kilograms, an increase of approximately one full nuclear weapon’s ...

LIS Technologies, which stands for Laser Isotope Separation, is developing lasers to excite and extract the uranium-235 isotope that powers nuclear reactors. It was one of six companies selected ...
