A nuclear fission reaction occurs when a uranium-235  atom is bombarded with a neutron. This reaction is used to produce energy in a nuclear power plant. Why is it not possible to carry out a nuclear fusion reaction in a nuclear reactor?

• A fusion reaction releases harmful rays
• A fusion reaction is difficult to control
• A fusion reaction requires extremely low temperature and pressure
• A fusion reaction requires extremely high temperature and pressure
