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