Question: what chemical reactions happen in a nukula chamber

Ian Simpson answered on 21 Jun 2014:

Nuclear power releases some of the energy stored in the nuclei of atoms by a process called nuclear fission. Typically elements that have very large nuclei like Uranium are used as the fuel in the reaction. If a slow moving neutron (another part of the nucleus) is made to hit a nucleus of one of the fuel atoms it will sometimes split the nucleus in two and release a lot of energy and sometimes also additional neutrons. If those neutrons then hit another nucleus of the fuel the same happens again. This can reach a point where a chain reaction occurs releasing massive amounts of nuclear energy and is what happens in both a nuclear power station and a nuclear bomb.
