1Where should we put the nuclear power stations?The deciding factors2The nuclear rods produce a lot of heat. This heats the water or gas in the closed system (pale blue). This then takes the heat to the heat exchanger which turns the darker blue water into the steam which turns the turbine which generates the electricity. The cooling tower returns the steam to water and it goes round again. This shows a cooling tower but that is not the only way to cool the water. In the UK we use often use the sea instead2How does nuclear power work?33Where were the first nuclear power stations sited and when?Issues: distance from urban centres access to national grid good water supply for cooling absence of natural hazards transport links proximity to both civil airports and military installations4We are now going to look in a bit more detail at the issues5These looked at together as they are linked
