Nuclear power is the use of nuclear reactions to release energy from the nuclei of atoms. It is used to generate heat, which can be harnessed in the nuclear power plant to generate electricity.
Nuclear power is currently used in a number of countries to generate electricity. The first reactor was created by Fermi and Szilard in 1942. This work then went on to become the Manhattan Project. The Manhattan Project would ultimately create the first nuclear weapon and resulted in the deaths of tens of thousands of people when the weapons were used on two Japanese cities at the end of the second world war.
Modern nuclear power plants use fission reactions, but there are current attempts to create a nuclear reactor that uses fusion reactions. Fission reactions occur when a large atomic nucleus splits into two lighter nuclei. These reactions release energy, which is used to heat water. This water turns into high pressure steam and the high pressure steam drives turbines connected to generators to spin. The generators generate an electric current which can then be sent to buildings through a system of cables.
Nuclear power is one of the most widely used low-carbon electricity generation methods. There are 31 countries in the world that have nuclear power plants, with five countries using nuclear power as their main energy source. Unlike coal or gas power stations, nuclear power does not involve burning, a process which emits carbon dioxide into the atmosphere. Nuclear power is also very reliable, as it doesn’t rely on weather conditions like solar and wind power.
Nuclear reactors can also be used to power submarines, allowing them to stay underwater for months at a time. Nuclear power is being tested as a means of fueling long human missions to other planets.
Even though it is widely used around the world, there some negative aspects of nuclear power and many people disagree with it being used. The waste from the power stations remains radioactive and dangerous to life for many thousands of years. While modern nuclear power stations are very safe, there have been a number of disasters relating to nuclear power. The most infamous was the Chernobyl disaster in which 31 people died directly from the accident and there is an estimated 4,000 deaths as a result of exposure to radiation.

How Tos about What is Nuclear Power?
Engage students with a hands-on nuclear power simulation activity
Set up a simple classroom role-play where students act as engineers, safety inspectors, and community members to explore how a nuclear power plant works. This interactive approach helps students visualize processes and understand real-world applications.
Introduce basic concepts using visual aids
Display diagrams and pictures of nuclear reactors, cooling towers, and fuel rods to make abstract ideas tangible. Visuals boost comprehension and retention for all learners.
Facilitate a group discussion on nuclear energy pros and cons
Encourage students to brainstorm the benefits and potential risks of nuclear power. Guide them to consider safety, environmental impact, and energy needs.
Connect nuclear power to everyday electricity use
Relate the topic to how students’ homes and schools get electricity. This helps bridge classroom learning with real-life relevance.
Assign a creative project to summarize nuclear power concepts
Have students create posters, slides, or short videos explaining how nuclear power works and its effects. Creative projects reinforce learning and allow students to express understanding in their own words.
Frequently Asked Questions about What is Nuclear Power?
What is nuclear power?
Nuclear power is energy produced by splitting atoms in a process called nuclear fission. This generates heat, which is used to create steam that turns turbines and produces electricity.
How does a nuclear power plant work?
A nuclear power plant works by using nuclear fission to heat water into steam. The steam spins turbines connected to generators, which produce electricity for homes and businesses.
What are the advantages and disadvantages of nuclear power?
Advantages of nuclear power include low greenhouse gas emissions and reliable energy. Disadvantages include radioactive waste, high costs, and potential safety risks.
Why is nuclear power important in the energy mix?
Nuclear power is important because it provides a stable source of electricity and helps reduce reliance on fossil fuels, which can lower carbon emissions and combat climate change.
What is the difference between nuclear power and fossil fuels?
Nuclear power uses atomic reactions to generate energy, while fossil fuels are burned to release energy. Nuclear power produces less air pollution and carbon dioxide compared to fossil fuels.
