Nuclear power plants use heat produced during nuclear fission to heat water. … The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine. As the turbine blades turn, they drive generators that make electricity.
How does a nuclear power plant work 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.
How does nuclear energy produce electricity for kids?
To produce nuclear power, you need uranium atoms. … When you split a uranium atom into two smaller atoms, it releases heat. This heat is used to produce steam, which turns enormous turbines in a nuclear plant. These turbines power generators that produce electricity.
How much electricity does nuclear generate?
Nuclear energy now provides about 10% of the world’s electricity from about 445 power reactors. Nuclear is the world’s second largest source of low-carbon power (29% of the total in 2018). Over 50 countries utilise nuclear energy in about 220 research reactors.
What happens if a nuclear power plant explodes?
What happens when there is a nuclear power plant accident? A nuclear power plant uses uranium fuel to produce steam for generating electricity. … If a nuclear power plant accident occurs, heat and pressure build up, and the steam, along with the radioactive materials, may be released.
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.
Can a nuclear power plant power a city?
U. S. Nuclear Cont. A 1,000-megawatt power plant can meet the needs of a city the size of Boston or Seattle.
