3 Explain how the nuclear fission process is controlled in a nuclear power station
A uranium atom absorbs a neutron then splits Each fission reaction releases neutrons These neutrons can go on to cause other fission reactions to occur Nuclear waste is radioactive Nuclear power is risky Einstein has showed that E=mc2 Chain reactions lead to explosions Control rods absorb neutrons Coolant removes heat from fuel rods A constant fission rate is required
