The chief environmental drawback of nuclear fission is:
AProduces long-lived radioactive waste
BReleases lots of CO2
CGenerates only small amounts of energy
DCannot be controlled
Answer & Solution
Correct answer: A. Produces long-lived radioactive waste
1. Nuclear fission yields huge amounts of energy with no CO2 emission.
2. The drawback is the radioactive by-products.
3. Many fission products remain radioactive for thousands of years.
4. Safe long-term storage is expensive and difficult.
5. So the main environmental issue is radioactive waste.
