Nuclear fission is a reaction: a nucleus of an atom targets a neutron, it hits it, then the neutron will split into two or more nuclei, creating a very large amount of energy, the nuclei will hit another neutron, creating more energy.Humans use that energy to heat up water, which creates steam, the steam turns the turbines making electricity.If nuclear fission reaction creates too much heat, the control rods, will take care of that, control rods are made of metal material, it is insert between the fuel rods where fission happens.This tecnology has been used for about 50 years.The nuclearfission power plant generates a lot of energy for us to use, but having a meltdown is very dangerous.A meltdown happens when the nuclear fissionreaction makes to much energy as heat, it then melts, the meltdown could cause several explosions, the explotions could whip off a lot of housesnearby and dozons of people could be killed or injured, not only people won't have houses, the explosions will make a cloud of dangerous radioactiveparticles, which then will fall to the ground, if humans or any alive things contact with it will die .For example, theThree Mile Island nuclear power plantgenerates most electricity for homes in that area, but it suffered a meltdown and never reopene
