Nuclear power station. External view of a nuclear power station. The domes at lower left and lower right each house a pressurised water reactor. These reactors use a fissile material,such as uranium-235,as fuel. When a neutron subatomic particle strikes a uranium-235 nucleus,the nucl- eus may split,releasing energy and more neutrons. The heat is removed by water which then passes through a heat exchanger to boil water in a secondary circuit. This then drives a turbogen- erator to make electricity. Nuclear power stations produce no acid rain or greenhouse gases,but make radioactive waste. Photographed at Palo Verde in California,USA,where there are three reactors | |
