Georgia Power has announced the completion of cold hydro testing at Vogtle-3, one of two 1,100-MWe Westinghouse AP1000 pressurized water reactors under construction at the Vogtle site near Waynesboro, Ga.

Unit 3 construction is now approximately 94 percent complete, and the total Vogtle-3 and -4 expansion project is about 88 percent complete, according to the company’s October 19 announcement. The last major test for Vogtle-3 before initial fuel loading is hot functional testing.

The target in-service dates for the Vogtle nuclear expansion project remain November 2021 for Unit 3 and November 2022 for Unit 4, plant owner Georgia Power announced in an August 31 report to the Georgia Public Service Commission. The project is now approximately 87 percent complete.

Closed vessel testing has been completed at Vogtle-3 at the Georgia Power site near Waynesboro, Ga., the company announced on July 14. The completion of the milestone prepares Unit 3 for cold hydro testing, which is required ahead of initial fuel load.

Vogtle-3 and -4 are the first new nuclear power reactors built in the United States in the past three decades. The new units will be powered by AP1000 reactors.

Southern Company subsidiary Georgia Power, primary owner of the Vogtle nuclear power plant, announced on June 23 that it is resequencing certain planned activities at Vogtle-3 and -4, the two Westinghouse AP1000 units under construction at the site near Waynesboro, Ga.

While there has been some good news recently regarding the historically troubled nuclear new-build project at the Vogtle site in Waynesboro, Ga. (see here and here), the latest news on the subject does not fall into that category.

As a result of the COVID-19 crisis, Georgia Power Company is reducing the number of workers at its Vogtle-3 and -4 construction site, in Waynesboro, Ga., by approximately 20 percent, according to a recent joint Securities and Exchange Commission filing by the company and parent firm Southern Company.
