Nuclear Reactor Energy Production

Steps:

• Identify the core process: Nuclear reactors in power stations use uranium fission to release heat energy.
• Recall the energy conversion: This heat boils water into steam, which drives turbines to generate electricity.
• Evaluate options: Check each against fission process and power plant mechanics.
• Select the accurate description of reactor function.

Why C is correct:

• Nuclear reactors generate thermal energy via fission, which boils water to produce steam for turbine-driven electricity generation, as defined in standard pressurized or boiling water reactor designs.

Why the others are wrong:

• A: The statement is incomplete and does not specify the fission reaction of uranium-235 nuclei.
• B: Nuclear power stations use nuclear fission, not fusion, which occurs in experimental reactors like tokamaks.
• D: The major waste products are radioactive isotopes like cesium-137, not carbon dioxide.

Final answer: C
