The post Is Vogtle Nuclear Expansion on Schedule? CEO Sounds Confident appeared first on POWER Magazine.
“We still expect to meet the November regulatory-approved in-service dates for both Units 3 and 4,” Southern Company CEO Tom Fanning said during the company’s first quarter earnings call on April 30. The in-service dates he was referring to are November 2021 and November 2022 for Units 3 and 4, respectively, at the Vogtle nuclear expansion project near Waynesboro, Georgia. The project is owned by four partners: Southern Company subsidiary Georgia Power (45.7%), Oglethorpe Power Corp. (OPC, 30%), Municipal Electric Authority of Georgia (MEAG Power, 22.7%), and Dalton Utilities (1.6%).
Furthermore, Fanning said site managers continue to believe they can hit target dates set in the company’s “Aggressive Site Workplan,” which are May 2021 and May 2022, respectively. “Is it riskier than it was before? Yeah. But it’s still a reasonable objective; otherwise, we wouldn’t stick with it,” said Fanning.
About two weeks ago, Southern Company announced it would reduce the workforce on the project by 20% in an effort to mitigate the impacts of COVID-19.…
The two-unit Vogtle expansion in Georgia faces major challenges that are poised to derail its schedule and ramp up costs—and the project is already behind schedule, a consulting firm tasked with construction oversight of the project told regulators.
In revealing testimony filed with the Georgia Public Service Commission’s (PSC’s) public interest advocacy staff on November 30, Donald Grace, vice president of engineering for Cost Plus Technology—Nuclear Construction Oversight (CPT), noted that the total construction cost—which includes all owner-shared costs but excludes financing costs—to complete the two Vogtle units by the scheduled November 2021/2022 timeframe is $ 17.1 billion. Only about 60% of the project is complete, he said.
Meanwhile, the project faces several potentially debilitating challenges that could cause delays and drive up costs. Foremost among them are labor shortages. While Georgia Power noted about 7,000 workers were onsite as of December 4, according to Grace, “Obtaining sufficient numbers of qualified craft labor pipe fitters and electricians are necessary to support the planned installation rate for bulk piping and electrical commodities.”…
China National Nuclear Corp. (CNNC) completed the dome lift at Fuqing Unit 5—the world’s first power plant being constructed utilizing the HPR 1000 (also known as the Hualong One) reactor design—15 days ahead of schedule on May 25.
The feat was no small accomplishment. The dome weighs about 340 metric tons and has a diameter of 46.8 meters (more than half the length of a U.S. football field). It was said to be the world’s largest and highest dome lift ever undertaken at a nuclear construction site (Figure 1). The dome—composed of 153 prefabricated components divided into five layers—ensures the integrity of the unit’s reactor building.

“That the dome was lifted 15 days in advance proves that CNNC can construct the HPR 1000 which is a national key project in the field of nuclear power,” Wang Shoujun, chairman of CNNC, said in a press release.…
