Nuclear Power 2

The splitting of a nucleus into smaller nuclei is a ________ reaction

• Fusion

• Fission

• Chemical

• Combustion

This is an example of ?

• Fusion

• Fission

• Combustion

• Absorption

Where does fusion occur naturally ?

• Underwater

• All around us

• In the sun

• In the human body

What are the major risks for fission power ?

• A large amount of radioactive waste

• A large amount of fuel required

• Uncontrollable chain reactions (meltdown)

Which of these countries have banned nuclear power?

• Australia

• Italy

• America

• Korea

This is an example of ?

• Fusion

• Fission

• Chemical

• Combustion

[*] What would be the advantage(s) of using nuclear fusion to produce energy?

• no radioactive waste and more energy produced

• safer

• require less regulation

• more controlled energy produced, less radioactive waste produced

[*] What is the main difficulty with nuclear fusion?

• Can't maintain a chain reaction

• Inefficient

• Too hot

• Difficult to procure the fuel required

[***] Which of these processes describes 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

• Protons and neutrons change to electrons because the nuclei are so big

• When a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, and cause them to split

One disadvantage of nuclear energy is ___.

• Requires Fossil Fuel

• it leaves behind radioactive waste

• there are no disadvantages

• it emits large amounts of pollution into the atmosphere
