Nuclear Power is a special type of thermal electricity. Hydroelectric power generation is based on the energy contained in flowing water. Most thermal power generation is based on burning coal gas or wood to heat water to produce steam. Nuclear power generation uses the heat generated by a fission reaction to generate steam. A hydro station is located on a waterway that can be dammed.
Water flows into the station s powerhouse through the intake and enters into the scroll case.
The scroll case is a spiral area that surrounds a turbine. The spiral shape swirls the water in the same direction as the blades of the turbine. The turbine looks like a giant propeller that is turned by the swirling water. As the turbine turns the attached rotor also spins generating electricity. The potential energy of the river is converted into mechanical energy that in turn produces electrical energy.
