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.

A program of electron cyclotron heating (ECH) with 4 MW at 140 GHz has been launched for developing scenarios of stable high performance through control of the pressure and current density profiles on the EAST tokamak. Several electron cyclotron emission (ECE) diagnostics are under development as important components of the research program on EAST. The smaller HT-7 tokamak is equipped with a multichannel superheterodyne radiometer and an ECE imaging system. Physics issues including fluctuations driven by electron and ion modes, low frequency zonal flows, magnetic reconnection mechanisms, etc. were investigated on HT-7 using these two systems, which have been moved to EAST after some modifications. New systems, including a 32-channel ECE system and an ECE imaging system of 24(radial) × 16(vertical) channels, are under development. These new systems are designed for the ECH plasma regimes and provide long-range correlation measurements of plasma turbulence. A grating polychromator ECE system has been installed for measurement of the Te profile covering the whole operational range of toroidal magnetic field on EAST.
