Final answer:
Nuclear energy is used to generate steam for turbines in a nuclear power plant. The nuclear reaction produces heat which boils water and creates steam. The steam then flows through the turbine, generating electricity.
Step-by-step explanation:
Nuclear energy is used to generate steam for turbines in a nuclear power plant.
The nuclear reaction in a nuclear reactor produces a large amount of heat.
This heat is used to boil water, creating steam. The steam then flows through the turbine, causing it to spin and generating electricity.
