such as uranium and plutonium, requiring complex and dangerous enrichment processes. Uranium enrichment, for example, transforms uranium-238 into uranium-235, which is more reactive. This process ...

Nuclear reactions show the irradiation of uranium-235 at the Savannah River Site. This produced the intermediate neptunium-237, which was then transformed into plutonium-238. Pu-238 fueled the first ...

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 ...

then some of the more common uranium 238 would be transmuted into "element 94," now called plutonium. Like uranium 235, element 94 would be an incredibly powerful explosive. In 1941, von ...

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 ...
