Radioactive Waste From Uranium Mining and Milling | US EPA

Uranium is a naturally-occurring radioactive element that has been mined and used for its chemical properties for more than a thousand years. It is now primarily used as fuel for nuclear reactors that make electricity. Uranium can be recovered in two ways: by conventional mining of the rock (ore), or by using strong chemicals to dissolve uranium …

How Uranium Mining Works | HowStuffWorks

Uranium-238 measures as the most abundant isotope of the element on Earth and can be found in rocks and seawater. But it's not as radioactive as uranium-235, the best-known form of uranium used to create nuclear reactions. In this article, we'll chart the uranium mining process, tracking the element as it transitions from ore to fuel pellets ...

Nuclear explained

Nuclear fuel—uranium . Uranium is the fuel most widely used by nuclear plants for nuclear fission. Uranium is considered a nonrenewable energy source, even though it is a common metal found in rocks worldwide. Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart.

History of Nuclear Energy

Like uranium-235, element 94 would be an incredibly powerful explosive. In 1941, von Weizsäcker went so far as to submit a patent application for using a uranium machine to manufacture this new radioactive element. By 1942 the military objective was wound down as impractical, requiring more resources than available.
