U-238 is the most abundant form in the environment. U-235 can be concentrated in a process called “enrichment,” making it suitable for use in nuclear reactors or weapons. 238 U occasionally decays by spontaneous fission with probability of 0.000055%.

The production of energy in nuclear reactors is from the 'fission' or splitting of the  Uranium was apparently formed in supernovae about 6.6 billion years ago. While it is not common in the solar system, today its slow radioactive decay provides  On this page: Uranium Isotopes; Enriching Uranium. Uranium Isotopes. When uranium is mined, it consists of approximately 99.3% uranium-238 (U238), 0.7%   Dec 29, 2020 By capturing a neutron, it becomes a nucleus of plutonium-239.

238 U occasionally decays by spontaneous fission with probability of 0.000055%. 238 U is a fissionable isotope, but is not fissile isotope. 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.

Examples 232Th, 235U and 238U each form the start of long decay series comprising multiple α- and β emissions which eventually produce various isotopes of Pb:  307.e Absolute Determination of the U235/U238 Ratio with Optical Interferometer 1 — Uranium lines U-238 - 5,027.398 Е and U-235 - 5,027.295 Е excited.

2013-02-05 Natural Uranium • There are three naturally occurring isotopes of uranium: U-234 U-235 U-238 • All th l li d l hAll three are long lived alpha-emitters. • U-238 is the head of the uranium decay series of which U-234 is a member. • U-235 is the head of the actinium decay series. • These decay series include alpha, beta and gamma emitters. 4 U-238 is the most abundant uranium followed by U-U- 235 and 234. The difference between the three isotopes is the number of neutrons present in the nucleus.
