A massive water tank has been placed atop the containment vessel and shield building roof at Vogtle-3, one of two AP1000 reactors currently under construction at Southern Company’s nuclear expansion project near Waynesboro, Ga. The installation represents the final module placement for the unit and marks the latest significant milestone to be reached at the Vogtle site.

Module specs: The water tank, known as CB-20, is a major part of the AP1000’s advanced passive safety system, according to the Vogtle plant’s primary owner, Southern subsidiary Georgia Power. Standing 35 feet tall and weighing more than 720,000 pounds, the CB-20 module will hold approximately 750,000 gallons of water, which would flow down in the event of an emergency to help cool the reactor. The water can also be directed into the used fuel pool, while the tank itself can be refilled from water stored elsewhere on-site, Georgia Power said.
