By the end of the year the physicist Werner Heisenberg had calculated that nuclear fission chain reactions might be ... into "element 94," now called plutonium. Like uranium 235, element 94 ...

NASA has been committed to the exploration of planet Mars, and now scientists have decided to use nuclear fission energy as ...

But the neutrons are much more likely to trigger new fission events if ... in breeding weapons-grade plutonium from common uranium. In a heavy-water nuclear reactor, when neutrons bombard U ...

As a warning about how close we are to atomic holocaust, the Doomsday Clock stands at 90 seconds to midnight, the closest it has ever been since its invention in 1947. After creating the world's first ...

At the same time, uranium-233, the primary fission material produced from thorium, is harder to use for weapons purposes than uranium-235 or plutonium-239. This means there is less of a risk its ...
