May 31, 2015 · When uranium-235 undergoes a neutron-induced fission reaction, it will split into two smaller nuclei, which, in your case, are tellurium-137, ""^137"Te", and zirconium-97, ""^97"Zr", releasing neutrons and gamma rays in the process. So, you know that the uranium-235 nucleus must collide with a neutron, which is a subatomic paticle that has no electric charge and a mass approximately equal to ...

Plutonium Production - Fourmilab

Uranium exists in nature, but only 0.711% of natural uranium is U-235, so in order to build a bomb the costly and difficult process of enrichment must be performed to separate the U-235 from the 99.284% of U-238, which cannot sustain the fast chain reaction required in a weapon. Plutonium .

Plutonium-239 - Wikipedia

Plutonium-239 is an isotope of plutonium.Plutonium-239 is the primary fissile isotope used for the production of nuclear weapons, although uranium-235 has also been used. Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 and uranium-233.Plutonium-239 has a half-life of 24,110 years.

NRC: Uranium Enrichment

The gaseous diffusion process uses molecular diffusion to separate a gas from a two-gas mixture. The isotopic separation is accomplished by diffusing uranium [which has been combined with fluorine to form uranium hexafluoride (UF 6) gas] through a porous membrane (barrier), and using the different molecular velocities of the two isotopes to achieve separation.

Uranium 235 Fission - Nuclear Power

Uranium 235 Fission. Uranium 235 is a fissile isotope and its fission cross-section for thermal neutrons is about 585 barns (for 0.0253 eV neutron). For fast neutrons its fission cross-section is on the order of barns.Most of absorption reactions result in fission reaction, but a minority results in radiative capture forming 236 U. The cross-section for radiative capture for thermal neutrons ...
