Question: Q: What drives the turbine in a thermonuclear reactor? Read this paragraph and choose the correct option from the provided answers: Scientists are searching for ways to create controlled nuclear fusion reactions on Earth. Their goal is develop nuclear fusion power plants, where the energy from fusion of hydrogen nuclei can be converted to electricity. You can see how this might work in the Figure below . In the thermonuclear reactor, radiation from fusion is used to heat water and produce steam. The steam can then be used to turn a turbine and generate electricity. Choices: - magnets - heated oil - wind energy - heated water or steam A:
Answer: heated water or steam
