During the more than 500 above ground nuclear tests performed around the world, the fallout of Plutonium-239 rained down from ...

This, as he found out, isn’t something you should do lightly, as the one he used ended up containing an interesting mix of radioactive materials, including small amounts of plutonium-239 ...

Alfred Hitchcock's Notorious is arguably the first in the genre of post-war Nazi political thrillers, but that wasn't ...

The proposed solution to this problem is to instead use fast-neutron reactors, which “breed” non-fissile uranium-238 into plutonium-239 and plutonium-240, which can then be used as fresh fuel.

Because used nuclear fuel can be recycled several times through a fast nuclear reactor, it is worth more than gold.

In this 3rd part of the story of Kenneth D. Nichols, the father of Oak Ridge, you'll get to know Jackie, his wife and an ...

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 ...

The TBP solution captured the plutonium and uranium while the nitric acid/water solution retained unwanted byproducts from the reaction. The TBP solution was removed and treated with additional ...

But unfortunately this arrangement doesn't last very long. Because plutonium-239 self destructs, undergoing radioactive decay by spitting out a highly energetic alpha-particle to produce Uranium-235.

Ample reasons, most notably leadership skills, personality traits and qualifications, led to choosing General (then Colonel) ...
