How does a nuclear reactor?

Nuclear plant to create electricity, coal, oil or gas does not require anything like. The water is heated to steam only. The steam turns turbines and generate electricity.

Nuclear Power Plant: There are two types of nuclear power plants

1. Boiling water reactors

II. Pressurized water reactors

1.Boiling water reactors: Here is the flow of water around the fuel rods cool and steam riyaktarera is made. Riyaktara steam turbines and turbine generator from the vessel means the electricity is generated. Boiling-water-reactor-system

2Pressurized water reactors: Here riyaktarake cold flowing water to evaporate into the talks, so the pressure is not to be. The water is supplied to the flow of water and steam heat to another is made.

Pressurized water reactors

Riyaktarera inside:

Jirkaniyama plate is covered by uranium fuel is here. When turned on, the neutron and nuclear fission reaction means excessive amount of heat is generated. The neutron chain reaction that caused more heat. BWR Design

What meltdown?

Radake fuel is kept cool by water flow. If for any reason you can not be cold, it spreads itself melting and radiation environments. That it meltdown. Nuclear riyaktara at a certain time of the flow of water through the cooling system.
