Fission
Definition - the process of releaseing energy when the mass between the product nuclei and the reactants has been concerted into engery in order to obtain a much larger percentage of nuclei of a target invovled in relasesing energy.
Important features of:
- additional neutrons are emmited
- leads to "chain reaction" of neighboring molecules
- low yield of reaction
How it works
- process produces Fission Products which are "unstable radioactive isotopes produced when a uranium nucleus is split after captureing a neuron. - neutrons trigger the target nucleus causing it to split into many different components such as: - neutrons, fission product, and neutron - Once these products are realeased create a nuclear chain reaction
Energy released From Each Fission (according to PH261 Slides)
165 MeV ~ kinetic energy of fission products
7 MeV ~gamma rays
6 MeV ~kinetic energy of the neutrons
7 MeV ~ energy from fission products
6 MeV ~ gamma rays from fission products
9 MeV ~ anti-neutrinos from fission products
200 MeV
Controls of Nuclear Fission
- Only One neutron out of 2 or 3 will strike another molecules nucleus
- Controlled by a Neutron-Absorbing material
such as Graphite
