Does nuclear power use steam to turn a turbine?
Nuclear power comes from nuclear fission Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity.
Is a nuclear reactor just a steam engine?
No, a nuclear reactor alone is not a steam engine, but can be a part of external heat engine, it would be considered in the classes external combustion engines if both are joined. We call engines that burn fuels within itself and convert heat and pressure into mechanical work internal combustion engines .
Do all nuclear reactors use steam?
There are two types of nuclear reactors in the United States—both use steam to power a generator, but the difference is how they create it. Of the nation’s 96 reactors, 32 are boiling water reactors, while 64 are pressurized water reactors.
How is steam generated in a nuclear reactor?
The water in the core is heated by nuclear fission and then pumped into tubes inside a heat exchanger. Those tubes heat a separate water source to create steam. The steam then turns an electric generator to produce electricity. The core water cycles back to the reactor to be reheated and the process is repeated.
How many steam turbines are in a nuclear reactor?
In commercial power plants, there are two to four steam generators per reactor; each steam generator can measure up to 70 feet (21 m) in height and weigh as much as 800 tons. Each steam generator can contain anywhere from 3,000 to 16,000 tubes, each about .
What are the advantages and disadvantages of using nuclear energy to generate electricity?
Advantages and disadvantages of nuclear power stations
| Advantages | Disadvantages |
|---|---|
| Produces no polluting gases. | Waste is radioactive and safe disposal is very difficult and expensive. |
| Does not contribute to global warming. | Local thermal pollution from wastewater affects marine life. |
