Which of the following is true about fusion?

• Fusion happens in atomic bombs
• Fusion produces radioactive waste
• Fusion happens on the sun and stars
• Fusion happens at nuclear power plants

Which of the following is NOT true of nuclear fission?

• Fission produces pollution that causes cancer.
• Fission produces more energy per unit of fuel than fossil fuels.
• Fission produces radioactive waste.
• Fission uses the element uranium.

Nuclear power plants use __ as fuel.

• Uranium
• Krypton
• Barium
• Hydrogen

Which of the following is the correct order of events in a nuclear power plant?

• Uranium reactor, generator, turbine, transformer
• Transformer, turbine, generator, uranium reactor
• Uranium reactor, turbine, generator, transformer
• Turbine, Uranium reactor, Generator, Transformer

What is a beneficial aspect of nuclear fission?

• The ability to absorb energy
• The ability to release tremendous amounts of energy
• The ability to produce more energy than nuclear fusion
• There are no beneficial aspects of nuclear fission

An example of an uncontrolled fission reaction is _______________

• Nuclear power plants
• Radio active decay
• Atomic Bomb
• On the surface of the sun

Which of these statements correctly describes how the chain reaction occurs in nuclear fission.

• Uranium releases electrons to create   electricity
• When a nuclear fission reaction occurs, the electrons emitted can strike other nuclei in the sample, and cause them to split
• When a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei, and cause them to split
•  Protons and neutrons change to electrons because the nuclei are so big

The major drawback to nuclear fission reactors is ---

• the safe disposal of the radioactive waste
• finding large water sources to support the nuclear reactors
• mining the fossil fuels is dangerous for miners
• the pollution that is produced by the power plants
