Nuclear Fission Reaction Of Uranium 238

A fifth characteristic of nuclear reactions is that they release enormous amounts of energy.

What are the desirable properties of a compound to make it a good moderator. However low energy slow or thermal neutrons are able to cause fission only in those isotopes of uranium and plutonium whose nuclei contain odd numbers of neutrons eg.

What is a moderator. U 233 u 235 and pu 239. Now you may be asking if instability is the key cant you get something even more unstable and use that.

Nucleus nucleons p n nuclear matter nuclear force nuclear structure nuclear reaction. The first nuclear reactor to achieve controlled nuclear disintegration was built in the early 1940s by enrico fermi and his colleagues at the university of chicago. Surplus highly enriched uranium can be downblended with depleted uranium or natural uranium to turn it into low enriched uranium suitable for use in commercial nuclear fuel.

Fission may take place in any of the heavy nuclei after capture of a neutron. The much more abundant uranium 238 does not undergo fission and therefore cannot be. The answer is yes but if its more unstable then its not going to be found in nature.

Thermal fission may also occur in some other. This causes the nucleus to become. 238 u from depleted uranium and natural uranium is also used with recycled 239 pu from nuclear weapons stockpiles for making mixed oxide fuel mox which is now being.

The high energy neutrons released by fission travel at very high speeds fast neutrons and must be slowed down to increase its probability of hitting more uranium atoms and in turn induce more fission in the reactor.
