Q. Consider the following statements:
1.Fusion produces less radioactive waste compared to fission.
2.Uranium and plutonium are the primary fuel sources for nuclear fusion.
3.Nuclear fusion does not produce carbon dioxide.
How many of the statements given above are correct?
Answer: B
Notes:
Explanation –
Statements 1 and 3 are correct. Fusion reactions produce significantly less radioactive waste compared to fission reactions. This is because fusion reactions involve the merging of light nuclei, while fission reactions involve the splitting of heavy nuclei. Fusion doesn’t produce carbon dioxide like fossil fuels do. It’s considered a clean energy source because it doesn’t produce air pollution or contribute to climate change.
Statement 2 is incorrect. Uranium and plutonium are the primary fuel sources for nuclear fission, not fusion. Fusion reactions require isotopes of hydrogen, primarily deuterium and tritium, as fuel.
