Southern Nuclear was first when no one wanted to be.

The nuclear subsidiary of the century-old utility Southern Company, based in Atlanta, Ga., joined a pack of nuclear companies in the early 2000s—during what was then dubbed a “nuclear renaissance”—bullish on plans for new large nuclear facilities and adding thousands of new carbon-free megawatts to the grid.

In 2008, Southern Nuclear applied for a combined construction and operating license (COL), positioning the company to receive the first such license from the U.S. Nuclear Regulatory Commission in 2012. Also in 2008, Southern became the first U.S. company to sign an engineering, procurement, and construction contract for a Generation III+ reactor. Southern chose Westinghouse’s AP1000 pressurized water reactor, which was certified by the NRC in December 2011.

Fast forward a dozen years—which saw dozens of setbacks and hundreds of successes—and Southern Nuclear and its stakeholders celebrated the completion of Vogtle Units 3 and 4: the first new commercial nuclear power construction project completed in the U.S. in more than 30 years.

Unit 4 at Georgia Power’s Plant Vogtle has entered commercial operation, the company announced today. The new unit can produce enough electricity to power an estimated 500,000 homes and businesses, according to the company.

A seminal new report by the Southeast Nuclear Advisory Council and E4 Carolinas has identified the significant economic impact of the nuclear industry within the southeastern United States. The report, The Economic Impact of the Nuclear Industry in the Southeast United States, provides a baseline for future research into the crucial role nuclear power plants play in shaping regional economies and facilitating the shift to clean energy.

A team of researchers from the University of Georgia have shown that radioactive contamination in the Fukushima Exclusion Zone can be measured through its resident snakes.
