What is the science behind nuclear energy?

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.

Nuclear energy’s future as an electricity source may depend on scientists’ ability to make it cheaper and safer. … This process, nuclear fission, generates heat that is directed to a cooling agent—usually water. The resulting steam spins a turbine connected to a generator, producing electricity.

How nuclear energy works step by step?

In a nuclear energy plant, heat is produced from splitting atoms – a process called nuclear fission.

  1. Nuclear reactor creates heat that is used to make steam.
  2. The steam turns a turbine connected to an electromagnet, called a generator.
  3. The generator produces electricity.

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.

How is nuclear energy used in today’s society?

Nuclear energy produces electricity that can be used to power homes, schools, businesses, and hospitals. The first nuclear reactor to produce electricity was located near Arco, Idaho. The Experimental Breeder Reactor began powering itself in 1951.

Is nuclear energy clean?

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.

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.
