Question

which statement(s) correctly describe the fissionable material used in a nuclear power plant?
□ renewable resource
□ unstable isotopes
□ source of thermal energy
□ poses health problems
done

Explanation:

• renewable resource: Fissionable materials (like uranium) are non - renewable as their formation takes millions of years and they are finite in nature. So this is incorrect.
• unstable isotopes: Fissionable materials used in nuclear power plants (e.g., uranium - 235, plutonium - 239) are unstable isotopes. They undergo nuclear fission when bombarded with neutrons. So this is correct.
• source of thermal energy: During nuclear fission, a large amount of heat (thermal energy) is released. This heat is used to produce steam which drives turbines to generate electricity. So this is correct.
• poses health problems: The radiation emitted by fissionable materials and their by - products can cause serious health issues like cancer, genetic mutations if humans are exposed to them. So this is correct.

Answer:

• unstable isotopes
• source of thermal energy
• poses health problems
