Nuclear Power part 3



How a Nuclear Power-plant Works.


Nuclear power plants generate electricity by converting uranium 235 to energy which turns electric generators. The Power station contains a nuclear reactor (has fuel rods), cooling tower, generator, turbine, substation, and control room. First, Uranium atoms are exploding inside fuel rods since neutrons are crashing into them creating 2000 degree heat. Tons of pipes filled with water cool down the rods so that they dont melt and so they produce steam. A huge pipe transports the steam to a colossal turbine over 50ft in length. The steam blasts through the blades turning a axle at a extremely high speed with tons of force. A gearbox makes the axle spin faster where it is connected to an AC generator. Then the power is transformed in a substation to about 140,000 to 800,000 volts and sent over transmission lines to another substation that lowers the voltage so it can be used in industry and residential areas without frying electronics and damaging machinery. P.S they step up the voltage because its more efficient to have high voltage electricity on power lines.Then huge cooling towers turn the steam back into water and pump it back to the fuel rods so that they conserve water and don't need to pay an extremely high water bill. While these processes happen employees inspect machinery and make sure a nuclear meltdown does not occur back at the control room.
