Fission
Fission is the process of releasing energy when the mass between the product nuclei and the reactants has been concerted into energy in order to obtain a much larger percentage of nuclei of a target involved in releasing energy.
- additional neutrons are emitted
- leads to "chain reaction" of neighboring molecules
- low yield of reaction
- process produces Fission Products which are "unstable radioactive isotopes produced when a uranium nucleus is split after capturing 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 released create a nuclear chain reaction
(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
- Only One neutron out of 2 or 3 will strike another molecules nucleus
- Controlled by a Neutron-Absorbing materialsuch as Graphite
