In a nuclear power plant, you have a big pot of water that's under high pressure, and you have some fuel rods, and these fuel rods are encased in zirconium, and they're little pellets of uranium dioxide fuel, and a fission reaction is controlled and maintained at a proper level, and that reaction heats up water, the water turns to steam, steam turns the turbine, and you produce electricity from it.
在核电厂里， 你会看到 一大锅水，在一个高压的系统里， 你还会看到一些燃料棒， 这些燃料棒是被锆包裹， 它们是小球状的二氧化铀燃料， 裂变反应是受到控制的，被维持在一个恰当的程度， 这个反应使水加热， 然后水变成蒸汽，蒸汽带动涡轮机， 然后就可以发电了。
