  • Heat is generated in the reactor core when uranium-235 is split into lighter elements. The heat turns water into steam, which turns the turbines. The turbines turn generators and make electricity. Most reactors operate with a water temperature of around 315 ºC and pressure around 155 bar. In these extreme conditions, engineering design is critical particularly of safety and shutdown systems. The 2011 Fukushima plant disaster in Japan made worse by the failure of water pumps that were needed to cool the reactor core.
