Nuclear power station construction. Workers at the upper end of a steam generator for a nuclear power plant, covering it with plastic and fabric to keep it clean during transport to where it will be installed. A steam generator is a large structure (over 20 metres in height) used in pressurized water reactors (PWRs). Pressurized water, heated by the nuclear reactor, enters the lower end. Then a complex system of tubing transfers the heat into a new volume of water that exits through the top end here as steam. The steam is used to drive turbines to generate electricity. Photographed at the Framatome ANP facility at Chalon/Saint Marcel, France.
