Worked Solution & Example Answer:What is meant by nuclear fusion? Nuclear fusion is the process that occurs when two light atomic nuclei combine to form a heavier nucleus, accompanied by the release of energy - Leaving Cert Physics - Question d - 2016
Step 1
What is meant by nuclear fusion?
Answer
Nuclear fusion is the process that occurs when two light atomic nuclei combine to form a heavier nucleus, accompanied by the release of energy. This reaction occurs naturally in stars, including the Sun, where it is responsible for generating energy.
Step 2
Step 3
State one advantage and one disadvantage of each of these sources of nuclear energy.
Answer
Nuclear Fusion:
- Advantage: Hydrogen and Helium are abundant; fusion produces a significant amount of energy with minimal waste.
- Disadvantage: Fusion requires extremely high temperatures and is difficult to sustain, making it currently unfeasible for practical use.
Nuclear Fission: - Advantage: Fission can generate a large amount of energy from relatively small amounts of fuel and is currently used in many power plants.
- Disadvantage: Fission produces dangerous radioactive waste and poses risks associated with the potential for nuclear accidents.
