Georgia Power, primary owner of the Vogtle nuclear plant, announced last Friday that it will pay $413 million to settle a lawsuit brought against it last year by plant co-owner Oglethorpe Power Corporation.

To the ears of the nuclear community, the news from Georgia Power this morning may sound a bit like “Ode to Joy” from Beethoven’s Ninth: After years of delay, Unit 3 at the Vogtle nuclear power plant has entered commercial operation, becoming the first newly constructed power reactor in the United States in more than 30 years and the nation’s first Westinghouse-supplied Generation III+ AP1000 unit to be placed into service. The new unit joins Vogtle-1 and -2—1,169-MWe four-loop pressurized water reactors that entered commercial operation in the late 1980s.

Southern Nuclear, operator of Georgia’s Vogtle plant, has informed the Nuclear Regulatory Commission that all 364 inspections, tests, and analyses for Unit 4 have been performed, and all acceptance criteria for the new reactor have been met. Primary plant owner Georgia Power made the announcement last Friday.

Unit 3 at the Vogtle nuclear power plant has been successfully synchronized and connected to the electric grid, Georgia Power announced on April 1. The unit—one of two Westinghouse-supplied AP1000s at the Waynesboro, Ga., plant’s nuclear expansion site—becomes the first new U.S. power reactor to start up in seven years.

Unit 3 at the Vogtle nuclear power plant has achieved initial criticality, Georgia Power announced yesterday. A key milestone on the way to the reactor’s commercial operation, initial criticality demonstrates that operators have safely started, for the first time, the nuclear reaction inside the unit. (Fuel loading at Vogtle-3 began last October.)

Already for the second time this year, Southern Company has announced a delay to the expected commercial operation of Unit 3 at the Vogtle nuclear plant’s two-unit construction site. In addition, a delay to Unit 4’s startup is also possible, Southern said.

Southern Nuclear, operator of the two-unit Hatch nuclear plant, announced yesterday that it will seek subsequent license renewals (SLR) for both reactors.

The total bill for the reactor expansion project at the Vogtle nuclear plant in Georgia is now expected to exceed $30 billion, according to the Associated Press. The original price tag for the two Westinghouse AP1000 units was $14 billion.

Commercial operation dates for the two new reactors under construction at the Vogtle nuclear plant have been pushed back yet again, adding to the project’s total cost, Southern Company announced last week. The Vogtle plant is near Waynesboro, Ga.

During its February 17 fourth-quarter earnings call, Southern reported that the projected start dates for both reactors were being extended by three to six months. Vogtle-3 is now expected to begin providing electricity to Georgians in the fourth quarter of 2022 or first quarter of 2023, with Vogtle-4 coming on line in the third or fourth quarter of 2023.
