Resources :
7.17 know that nuclear reactions, including fission, fusion and radioactive decay, can be a source of energy
7.18 understand how a nucleus of U-235 can be split (the process of fission) by collision with a neutron, and that this process releases energy as kinetic energy of the fission products
7.19 know that the fission of U-235 produces two radioactive daughter nuclei and a small number of neutrons
7.22 understand the role of shielding around a nuclear reactor
7.25 know that fusion is the energy source for stars
______________
7.20 describe how a chain reaction can be set up if the neutrons produced by one fission strike other U-235 nuclei
7.21 describe the role played by the control rods and moderator in the fission process
7.23 explain the difference between nuclear fusion and nuclear fission
7.24 describe nuclear fusion as the creation of larger nuclei resulting in a loss of mass from smaller nuclei, accompanied by a release of energy
7.26 explain why nuclear fusion does not happen at low temperatures and pressures, due to electrostatic repulsion of protons
