Nuclear power involves

• A. Harnessing wind energy through turbines.
• B. Mining for uranium and the process of fission.
• C. The conversion of heat from burning fossil fuels into electricity.
• D. The splitting of atomic particles to release chemical energy.

Answer: (B)

Nuclear power involves obtaining energy by splitting atomic nuclei, which releases a large amount of heat. This energy typically comes from uranium fuel, which must be mined and prepared before use in a reactor. In the reactor, fission splits a nucleus into smaller parts, releasing heat and neutrons that keep the chain reaction going, and this heat is used to make steam to drive turbines.

The option that mentions mining for uranium and the fission process best captures both the fuel source and the mechanism by which nuclear power generates energy. The other options describe wind energy, converting heat from burning fossil fuels, or incorrectly refer to the released energy as chemical energy rather than nuclear energy.
