A series of firsts delivers new Plant Vogtle units
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.

In recent years there has been an increased interest in advanced reactors in the United States. Several concepts are being proposed by multiple vendors and start-ups, with an accelerated pathway to market. In particular, DOE has recently issued two awards aimed at deploying demonstration reactors and several more aimed at accelerating current research activities. An important activity related to commercialization of these concepts is licensing and the overall role of the regulator. Furthermore, central to licensing and safety analysis is the understanding of thermal-hydraulics phenomena, which present considerable differences compared to light-water reactors. In this panel we will address current thermal-hydraulic issues in the licensing of advanced reactor concepts and ongoing research on this topic.
