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.

The use of the statistical properties of nuclear resonances to calculate fission-product poisoning in the intermediate energy range is described. On the basis of the available theoretical and experimental information, estimates of the average fission-product cross section as a function of energy are given for the energy range 102 to 106 electron volts. Comparison is made with direct experimental measurements of intermediate energy absorption cross sections for several isotopes. Because of the unusually large level spacings for target nuclei which have even proton and neutron numbers or near-magic neutron numbers, the average fission-product cross sections obtained here are lower than those obtained in estimates which ignore this effect. The influence of various assumed statistical distributions of reduced neutron widths on the average cross section is discussed.
