What kind of energy transformation takes place in nuclear reactor?

Bystrom

In most electric power plants, water is heated and converted into steam, which drives a turbine-generator to produce electricity. Fossil-fueled power plants produce heat by burning coal, oil, or natural gas. In a nuclear knack plant, the fission of Uranium atoms hint at the reactor provides the heat to originate steam for generating electricity. Heat is produced hint at a atomic reactor when neutrons lay hold of Uranium atoms causing them to fission in a continuous chain backfire. Control elements, which are made of materials that fathom neutrons, are placed mid the tinder assemblies. When the control rudiments, or oversee rods as they are many a time called, are pulled away of the centre, more neutrons are available and the row reaction speeds break into bits, manufacturing more heat. When they are inserted into the core, more neutrons are absent-minded, with an increment of the chain reaction slows or stops, reducing the passion. Most commercial nuclear reactors use familiar water to remove the eagerness created hard by the fission modoperandi. These are called light water reactors. The water also serves to slow crestfallen, or "moderate" the neutrons. In this brand of reactor, the chain backfire devise not occur without the water to serve as a moderator.
