电能

Note that the direct conversion of nuclear energy to electricity is not how a nuclear power plant produces electricity; instead it uses the heat of a nuclear reaction to run a heat engine, and transforms the heat engine's resulting mechanical energy into electricity via magnetic induction.

请注意，核电站并不是通过直接将核能转换为电能来发电的，而是使用了热核反应驱动热力发动机，并通过磁感应将热机输出的机械能转化成电能。
