Fission reactions and nuclear energy
The nuclear reactor

E = mc2

In a nuclear power plant the nuclear fission reaction is slowed down. Neutrons are taken out of circulation by lead rods (control rods). Limiting the number of neutrons available to split uranium nuclei makes the reaction proceed slowly releasing energy at a manageable rate. Water is pumped through the reactor where it is heated to over 1,000oC. The steam is then used to spin turbines that drive generators producing electricity.
