Nuclear Energy Lesson

What is the primary difference between nuclear fission and nuclear fusion?

• Fission splits a heavy nucleus into smaller ones, while fusion combines small nuclei into a larger one.

• Fission combines small nuclei into a larger one, while fusion splits a heavy nucleus into smaller ones.

• Fission and fusion both split heavy nuclei into smaller ones.

• Fission and fusion both combine small nuclei into a larger one.

What is a major challenge of using nuclear fusion as an energy source?

• It typically takes more energy to create the fusion than the resulting energy produced.

• It produces too much radioactive waste.

• It is too expensive to build fusion reactors.

• It requires rare and expensive materials.

What is the role of control rods in a nuclear reactor?

• They contain nuclear fuel and help control the fission process.

• They convert steam into electricity.

• They cool down the reactor.

• They split atoms to release energy.
