Question

question 24 of 30
what is the source of energy in nuclear power plants?

a. alpha decay

b. combustion

c. fission

d. fusion

Explanation:

• Option A: Alpha decay is a type of radioactive decay, not the main energy source for nuclear power plants.
• Option B: Combustion involves burning fuel (like in fossil fuel plants), not used in nuclear power plants.
• Option C: Nuclear power plants use nuclear fission, where heavy atomic nuclei (like uranium - 235) split into smaller nuclei, releasing a large amount of energy.
• Option D: Fusion (combining light nuclei) is not currently used for commercial nuclear power generation as it is difficult to control and sustain.

Answer:

C. Fission
