Y13 - Nuclear Power

Nuclear power plants rely on which of the following reactions to generate energy?

• Fusion
• Half-life
• Fission
• Fusion or fission

Where does fusion occur naturally?

• Underwater
• All around us
• In the radioactive waste
• On the sun

This is an example of...

• Fission  reaction
• Fusion reaction
• Decomposition reaction
• Combustion

Which of the following best describes the process of nuclear fission? 

• Splitting an atom's nucleus apart 
• Separating an atom's electrons from its nucleus 
• Fusing two atomic nuclei together 
• Splitting an atom's electrons in half 

What is an advantage  of nuclear energy?

• radioactive waste
• no air pollution
• we will never run out
• it is the safest way to make energy

What controls the reaction within a nuclear reactor?

• Control Rods
• Moderator
• Containment building
• Reactor Vessel

the disintegration of an unstable atomic nucleus into one or more different nuclides

• nuclear radiation

• radioactive decay

• nuclear force

• radioactivity

the time required for half of a sample of a radioactive isotope to break down by radioactive decay to form a daughter isotope

• lifetime

• half-life

• decay rate

• radioactive decay

What happens to an isotope when its mass becomes too large and unstable? 

• It begins to emit radioactive energy, which can cause a fission reaction
• It begins to add protons in order to balance out the nucleus' mass
• It beings to emit only an electron because electrons are the largest subatomic particle 
• It begins to release compounds such as CO₂

Uranium is found in 

• the sun
• hydrogen
• rocks in the ground
• xrays
