How much material will be left if a radioactive isotope has a half life of 1.3 billion years in ... NettetAs uranium-235 is so rare in nature, uranium has to go through a process called enrichment so that enough uranium-235 is present to use as a fuel for nuclear energy. Uranium-238 can be converted to a fissile substance called plutonium-239, in a nuclear reactor, and then used for fission. Another isotope of uranium that is fissile is uranium … flame thrower distanceNettet26. jan. 2009 · According to the NEA, identified uranium resources total 5.5 million metric tons, and an additional 10.5 million metric tons remain undiscovered—a roughly 230 … flamethrower distributor problems

Nettet96% of the mass is the remaining uranium: most of the original 238 U and a little 235 U. Usually 235 U would be less than 0.8% of the mass along with 0.4% 236 U. … NettetFor its very long half-life, it is still present in the Earth’s crust. 235U decays via alpha decay (by way of thorium-231) into 231 Pa. 235 U occasionally decays by spontaneous fission with a very low probability of 0.0000000072%. 235 U is a fissile isotope, which means 235 U can undergo a fission reaction after absorbing a thermal neutron .
