Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.
How nuclear energy works step by step?
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.
What is the main cause of nuclear energy?
Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels.
Why is nuclear energy bad?
Nuclear energy produces radioactive waste
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
Where is nuclear used?
Top five nuclear electricity generation countries, 2019
|Country||Nuclear electricity generation capacity (million kilowatts)||Nuclear share of country’s total electricity generation|
What are the pros and cons for nuclear energy?
Nuclear power: The pros and cons of the energy source
- Pro – Low carbon. Unlike traditional fossil fuels like coal, nuclear power does not produce greenhouse gas emissions like methane and CO2. …
- Con – If it goes wrong… …
- Pro – Not intermittent. …
- Con – Nuclear waste. …
- Pro – Cheap to run. …
- Con – Expensive to build.
How long can we use nuclear power?
If the Nuclear Energy Agency (NEA) has accurately estimated the planet’s economically accessible uranium resources, reactors could run more than 200 years at current rates of consumption.
