Nuclear Power

Req 6b — How Plants Make Electricity

6b.
Visit a local nuclear power plant or nuclear reactor either in person or online (with your parent or guardian’s permission). Learn how a reactor works and how the plant generates electricity. Find out what percentage of electricity in the United States and in your state is generated by nuclear power plants, and by other methods. Make a graph of the information you find.

This option takes you from nuclear physics to a full working energy system. A reactor is only one part of the story. To explain how electricity is made, you have to connect heat, steam, turbines, generators, transmission, and the energy mix around them.

How a plant makes electricity

In simple terms, a nuclear power plant uses fission to make heat. That heat turns water into steam or transfers heat to a steam system. The steam spins a turbine. The turbine turns a generator. The generator sends electricity to the grid.

That means nuclear plants are not magic machines that produce electricity directly from atoms. They are heat engines, just like many other power plants, but the heat source is a nuclear reaction instead of burning fossil fuel.

What to find out during your visit or research

Questions your visit should answer

Use these to organize your notes
  • What kind of reactor or facility is it?
  • How does heat move from the reactor to the turbine system?
  • What safety and control systems are most important?
  • How much electricity comes from nuclear power in the United States and in your state?
  • What other major sources make up the rest of the energy mix?

Making the graph

Your graph should help your counselor compare sources quickly. A bar graph is often the easiest choice if you are comparing nuclear, natural gas, coal, hydro, wind, solar, and other sources between your state and the nation.

If your state has little or no nuclear generation, that is still worth discussing. It gives you a chance to explain how geography, policy, existing infrastructure, and local resources affect the energy mix.

The next requirement broadens the picture beyond power plants and shows how nuclear science helps people in many fields.
