What is the primary reaction in nuclear fission?
Click to flip
Nuclear fission involves the splitting of a large atomic nucleus into smaller nuclei.
Click to flip
What is the primary reaction in nuclear fusion?
Click to flip
Nuclear fusion involves combining light atomic nuclei to form a heavier nucleus.
Click to flip
How do the energy releases of fission and fusion compare?
Click to flip
Both processes release large amounts of energy, but fusion has the potential to release more energy than fission.
Click to flip
Which type of nuclear reaction occurs naturally in stars?
Click to flip
Nuclear fusion occurs naturally in stars.
Click to flip
What are the primary fuels used in fission vs. fusion?
Click to flip
Fission primarily uses Uranium-235 or Plutonium-239; fusion typically uses isotopes of hydrogen like deuterium and tritium.
Click to flip
Can nuclear fission have a chain reaction?
Click to flip
Yes, nuclear fission can sustain a chain reaction.
Click to flip
What is a key environmental concern with fission?
Click to flip
A key concern is radioactive waste and potential nuclear accidents.
Click to flip
How does the waste from fusion compare to fission?
Click to flip
Fusion waste is less hazardous, producing mainly helium, while fission produces long-lived radioactive waste.
Click to flip
What kind of reactions occur in hydrogen bombs?
Click to flip
Hydrogen bombs utilize nuclear fusion reactions.
Click to flip
Is achieving fusion more technologically challenging than fission?
Click to flip
Yes, achieving controlled fusion is currently more technologically challenging.
Click to flip
What are the byproducts of nuclear fission?
Click to flip
Byproducts of fission include smaller atomic nuclei, free neutrons, and radioisotopes.
Click to flip
What is required to sustain nuclear fusion?
Click to flip
Sustaining fusion requires extremely high temperatures and pressures.
Click to flip
Which reaction is currently used by nuclear power plants?
Click to flip
Nuclear power plants currently use fission reactors.
Click to flip
Why is fusion considered more environmentally friendly?
Click to flip
Fusion is considered more environmentally friendly as it produces minimal radioactive waste and no carbon emissions.
Click to flip
What development is needed for fusion energy to become viable?
Click to flip
We need breakthroughs in achieving stable, net energy positive reactions.
