The Virgil C. Summer Nuclear Generating Station made history in 2013 by being the first nuclear power plant to start construction in the United States in over 30 years. The concrete base was placed in March 2013 and other components were added throughout the year, including heavy equipment shipped from South Korea. See a recap of the construction last year in the video below.
VC Summer currently has one nuclear reactor that has been generating electricity since 1984. The two reactors under construction are the new Westinghouse AP1000 design are are planned to be online in 2018.
