Nuclear Power Plant

Basic Principle:
When nuclear fission happens huge amount of heat is produced. This heat is used to vaporize the water to make steam. Steam flows to turbine and electricity is produced.
Working Principle:
Reactor of a nuclear power plant is similar to the furnace of a steam power plant. The heat is liberated in the reactor due to the nuclear fission of the fuel. The heat is take a up by the coolant circulating through the reactor core. Hot coolant leaves reactor at top and then passes through the tubes of steam generator. Water converts to steam runs the turbo- generator.
