U-238 has 4 more neutrons than U-234 2011-01-23 I know I need 19 of it for every 1 U-235 to make fuel cells, but still the rate of which im getting each of them is never going to be enough. now I also know it can be used to make cannon shells and bullets, but the ratio is 1 U-238 for each magazine/shell. and with what I have stock piled up already, i'd be making enough to invade a few planets. Uranium is found in nature as the isotopes 238 U, 235 U, and 234 U. 238 U comprises over 99% of uranium found in nature, where it is mixed with 0.7% 235 U and 0.01% 234 U. 238 U has the longest half–life of the three isotopes (4.5 billion years), making it the least radioactive isotope and the isotope most likely to cause chemical toxicity rather than radiation injury. Problem #58: A sample of rock contains 64.27 mg of U-238 (isotopic mass 238.0508 amu) and 22.66 mg of Pb-206 (isotopic mass 205.9745 amu). Assuming that radioactive decay of U-238 is the only source of Pb-206, estimate the rock's age.

238 U is not capable of undergoing fission reaction after absorbing thermal neutron, on the other hand 238 U can be fissioned by fast neutron with energy higher than >1MeV. Uranium-238 is, along with uranium-235, one of the refined products of uranium ore when the ore is processed through a centrifuge, or the Kovarex enrichment process. Uranium-238 is vastly more common than uranium-235, with a 99.3% chance of appearing after being processed. Both isotopes of uranium are the main ingredients for most components of nuclear power generation.

2017-12-31 · U-238 does not undergo fission with lower-energy neutrons, while U-235 does. the aim of nuclear reactors is to generate energy through nuclear fission reactions. U-235 is a fissile isotope, meaning that it can split into smaller molecules when a lower-energy neutron is fired at it. this process releases neutrons and energy in the form of both gamma rays and kinetic energy (stored in neutrons

Since too few neutrons are born from fission at the energy required to fission U-238 (and other non-fissile isotopes), a reaction with only U-238 is not sustainable. All neutrons can cause fission in U-235, so its reaction is sustainable. 2017-12-31 U-238 Decay Series Isotope half-life gamma energies (KeV) U238. 4.468 x 10 9 years. Th234. 24.1 days.
