The first steam generator was successfully placed into Vogtle Unit 3 containment on Aug. 15. There are two steam generators per unit in the AP1000 design.
The 1.4 million pound, 78-feet long component was the first lift with the new Lampson crane, which will be used for major lifts going forward.
Steam generators are heat exchangers used to convert water into steam from heat produced in the nuclear reactor core. Each generator is a vertical-shell U-tube evaporator with integral moisture separating equipment. Simply put, high temperature water from the reactor coolant system flows through more than 10,000 tiny tubes in the steam generator and turns water into high pressure steam to spin the turbines.
