How do nuclear power plants generate electricity, and what are major waste issues?

• A. Fission heat generates steam to drive turbines; long-lived radioactive waste requires secure, long-term storage and containment.
• B. Fusion generates electricity directly; no waste.
• C. Nuclear plants run on fossil fuels; no waste.
• D. They use wind energy to drive turbines; no waste.

Answer: (A)

Electricity in a nuclear plant is produced from heat generated by fission in the reactor. That heat boils water to create steam, which drives a turbine connected to a generator. The big waste issue is that fission leaves radioactive waste, including spent fuel, that stays hazardous for long periods and needs secure, long-term storage and containment, often with cooling and eventually placement in deep geological repositories. The other descriptions aren’t accurate representations of how nuclear power works: fusion isn’t the method used in current electricity generation and would still involve waste; nuclear plants don’t run on fossil fuels; and wind energy isn’t part of the nuclear plant’s operation.
