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.

As the result of an attempt to prepare unordered compounds of graphite containing more than 1.5 × 10-3 acceptor per carbon atom by the introduction of both chemical acceptors and radiation damge centers, evidence has been found for mutual destruction of chemical acceptors and damage centers. An analysis of the kinetic behavior of the mutual destruction indicates that the extent of destruction is independent of the order in which the radiation damaging and chemical treatments are carried out. From some auxiliary experiments made necessary by the discovery of the above interaction it is concluded that the graphite bisulfate residue compounds are stable at room temperature, and that the bisulfate ion is not appreciably decomposed by the gamma flux in the reactor during short irradiations. The dependence of some electrical properties of graphite on the concentrations of both chemical acceptors and radiation damage centers has been analyzed on the basis of the two-band theory of a semiconductor above its degeneracy temperature. It is concluded that whereas the Hall effect may be reasonably well understood the behaviors of the electrical resistance and magneto-resistance cannot be understood in terms of this theory, so that the introduction of additional hypotheses appears necessary.
