#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
#7.20
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
#7.22
understand the role of shielding around a nuclear reactor
#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
#7.25
know that fusion is the energy source for stars
#7.26
explain why nuclear fusion does not happen at low temperatures and pressures, due to electrostatic repulsion of protons
