First major new US nuclear plant for decades goes live

The US’ first new utility-scale nuclear power plant in decades has reached 100% power output, six years behind schedule and $21bn over budget.
Georgia Power officials have announced 100% power output from Unit 3 at Plant Vogtle, reaching about 1,100 MW. The first reactor in the two-unit expansion of the site in Waynesboro, Georgia, is due to commence commercial operation this month, powering an estimated 500,000 homes and businesses.
It is the only new utility-scale nuclear power plant to be built in the US for several decades, but the project has been beset by numerous construction and other delays.
Southern Company, parent company of Georgia Power, sought a licence to expand the plant and build two new reactors in 2008. At the time, the reactors were means to cost $14bn and be complete by 2017. The final price tag has reportedly topped $35bn.
Initial criticality in Unit 3 began in March this year as the nuclear process within the reactor was initiated, splitting atoms, producing heat and enabling the production of steam. The reactor started generating electricity in April and was successfully synchronised and connected to the grid.
‘Unit 3 is currently undergoing testing through the full range of plant operations, including safely running at various power levels and operating through real-life conditions just as it will over the next 60 to 80 years after the unit enters commercial operation,’ according to Kim Greene, Chairman, President and CEO of Georgia Power.
The reactor of Unit 4 at Vogtle received nuclear fuel and completed hot functional testing on 1 May. It is anticipated to enter commercial operation later this year or early 2024.
