Transcription: In a pressurized water reactor, water is enclosed in three separate but interacting loops. In loop one, water becomes intensely hot as it absorbs heat from the energy of nuclear fission. But because it is under very high pressure, the water doesn't boil and remains a liquid. Pipes from loop one wind through a steam generator tank that is part of a second, lower pressure water loop. Heat from loop one boils the water in the steam generator, and the energy from the steam the steam powers turbines that drive electricity generators. The steam is then cooled and condensed in a heat exchange with a ...
