Fissionable uranium isotope

WebUranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor. Another fissile isotope, uranium-233, can be produced from natural thorium and is also important in nuclear technology. WebWhen bombarded by neutrons, certain isotopes of uranium and plutonium (and some other heavier elements) will split into atoms of lighter elements, a process known as nuclear …

WebJun 1, 2010 · Many had never heard of uranium until August 6, 1945—65 years ago—when radio broadcasts and newspapers announced that the most powerful weapon ever created had been dropped on a city in Japan, ending the war 22 days later. ... the fissionable uranium isotope, was separated from U-238, the heavier, more stable isotope, using a … WebUranium 238. Uranium 238, which alone constitutes 99.28% of natural uranium, is the most common isotope of uranium in nature. Uranium 238 has the longest half-life (4.47×10 9 years), and therefore its abundance is so high. Uranium 238 is a fissionable isotope but is not a fissile isotope. 238 U belongs to primordial nuclides because its half ...
