He chart below shows the properties of nuclear fission and nuclear fusion. Type of nuclear reaction 1 2 3 4
Nuclear fission Produces lesser amount of energy than fusion. Involves combining of atoms to release energy Takes place at high temperature and pressure It can be controlled to generate electricity
Nuclear fusion Produces a large amount of energy in the sun Involves breaking up of atoms to produce energy Takes place at low temperature and pressure It cannot generally be controlled
