Southern Co. just released this video documenting four years of construction progress on two new reactors at Georgia's Plant Vogtle – from their early site work to the recent placement of the lower containment vessel bowl inside unit 3.

Units 3 and 4 at the plant, along with two new units at the V.C. Summer plant in South Carolina, will be the first Generation III Westinghouse AP1000 reactors in the United States. Reactors under construction in Sanmen, China, are the world's first AP1000s and have informed construction of the new units in the U.S. The first Sanmen AP1000 recently saw completion of a majority of its structural work.
