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.

A spokesperson for Georgia Power has confirmed that the projected in-service date for the new Vogtle-3 reactor remains the third quarter of 2022, according to an article published on January 27 on the Power magazine website. The in-service date for Vogtle-4 is targeted for the second quarter of 2023, the spokesperson said.

Westinghouse Electric Company and Southern Nuclear have agreed to a plan to install four Westinghouse lead test assemblies in Vogtle-2, a 1,169-MWe pressurized water reactor located in Waynesboro, Ga. Four lead test assemblies containing uranium enriched up to 6 percent U-235 will be loaded in Vogtle-2 in 2023, marking the first time that fuel rods with uranium enriched above 5 percent U-235 are put in use in a U.S. commercial power reactor.

Georgia Power has revised the projected commercial operation dates for Vogtle-3 and -4 a total of four times this year—most recently in October—but some experts are saying that at least one more delay is probable.

The Nuclear Regulatory Commission will increase its oversight of Vogtle-3—one of the two Westinghouse AP1000 reactors under construction at the Vogtle nuclear power plant in Waynesboro, Ga.—after finalizing two inspection findings involving the unit’s safety-related electrical cable raceway system. Vogtle’s operator, Southern Nuclear, was informed of the decision in a November 17 letter.

The agency had launched a special inspection at Vogtle-3 in June of this year to determine the cause and extent of construction quality issues in the raceway system, which consists primarily of conduits and cable trays designed to prevent a single event from disabling redundant safety-related equipment.

In what has become for nuclear advocates an all-too-familiar refrain, Georgia Power has made another revision to the Vogtle nuclear expansion project schedule. The company now predicts a Unit 3 in-service date in the third quarter of 2022 and a Unit 4 in-service date in the second quarter of 2023, representing a three-month shift for each unit.

Oversight of the Vogtle nuclear new-build project will be increased if the preliminary conclusions in an August 26 Nuclear Regulatory Commission special inspection report are finalized.

Conducted from June 21 to July 2, the inspection looked into the cause and extent of construction-quality issues in the safety-related electrical cable raceway system at Vogtle-3.

Georgia Power yesterday announced that due to 'productivity challenges' and the need for 'additional time for testing and quality assurance,' it has revised the schedule for the Vogtle-3 and -4 nuclear expansion project. The new schedule pushes back the Unit 3 in-service date to the second quarter of 2022 and the Unit 4 date to the first quarter of 2023—a three-to-four-month shift for each unit.

Caputo

The Nuclear Regulatory Commission’s Annie Caputo will depart the agency when her term expires at the end of this month, NRC Chairman Christopher Hanson said yesterday. Her departure will leave the five-seat panel with only three commissioners—the minimum number required for it to conduct business—as former chairman Kristine Svinicki resigned in January of this year.

At this writing, Caputo has not announced her post-NRC plans.

Remaining on the commission are two Democrats, Hanson and Jeff Baran, and one Republican, David Wright. President Biden has not named a replacement for either of the vacancies and can choose only one Democrat, since no more than three commissioners can be from the same political party.

The Nuclear Regulatory Commission has launched a special inspection at the Vogtle new-build site to identify the errors that necessitated construction remediation work on Unit 3’s electrical cable raceway system.

Georgia Power recently pushed back its projected commercial operation date for Vogtle-3 from December of this year to January 2022, but now some engineering and financial experts are saying that this revised date is too optimistic.

The commercial start date for Unit 3 at the Vogtle construction site near Waynesboro, Ga., has been pushed back to January of next year, adding some $48 million to the cost of the nuclear new-build project, according to Georgia Power and Southern Nuclear officials who were testifying at a May 18 hearing before the Georgia Public Service Commission.

To reach President Biden’s goal of cutting U.S. carbon emissions in half by 2030 and to have a net-zero carbon economy by 2050, some environmentalists are reconsidering their opposition to nuclear energy’s role as a climate crisis solution. According to the article, The controversial future of nuclear power in the U.S., from National Geographic, nuclear power has a lot going for it. Its carbon footprint is equivalent to wind, less than solar, and orders of magnitude less than coal. Nuclear power plants take up far less space on the landscape than solar or wind farms, and they produce power even at night or on calm days.

Southern Company is targeting December for placing Vogtle-3 in service, according to Tom Fanning, the company’s chairman, president, and chief executive officer, who spoke with financial analysts on April 29 in its first-quarter earnings call. “The site work plan now targets fuel load in the third quarter and late December 2021 in-service date for Unit 3,” Fanning said. “Of course, any delays could result in a first-quarter 2022 Unit 3 in-service date.”

Georgia Power yesterday announced two significant milestones at the Vogtle nuclear plant’s expansion project: the commencement of hot functional testing at Unit 3 and the placement of Unit 4’s passive containment cooling water storage tank, known as CB-20.

Vogtle-3, the first of two 1,100-MWe AP1000 pressurized water reactors under construction at the Vogtle plant near Waynesboro, Ga., may not go into service in November as planned, Southern Company subsidiary Georgia Power has announced.

According to a March 19 filing with the Securities and Exchange Commission, the date for starting commercial operation at Unit 3 could be delayed by a month or more at a cost to Georgia Power of approximately $25 million per month. “While [Vogtle plant operator] Southern Nuclear continues to target a November 2021 in-service date for Unit 3, the schedule is challenged and … a delay is likely,” Georgia Power stated. The filing made no mention of changes to Unit 4’s scheduled start date of November 2022.

The $111.2 million in financial assistance awarded by the Department of Energy in late 2018 to nuclear fuel developers Framatome, General Electric, and Westinghouse for the development of accident tolerant fuel has yielded some encouraging results.

Framatome reports that the first 18-month fuel cycle test of its GAIA Enhanced Accident Tolerant Fuel (EATF) technology, conducted at Southern Nuclear’s Vogtle-2, has “demonstrated expected results and excellent performance.”

And last month, Westinghouse announced that the topical report on its Advanced Doped Pellet Technology fuel has been accepted for review by the Nuclear Regulatory Commission, calling the decision “a major achievement for the advanced fuel portfolio Westinghouse is developing.”

The unfortunate effects of the COVID-19 pandemic on nuclear new-build projects haven’t stopped with Vogtle: EDF Energy this morning reported that the expected startup date for Unit 1 at its Hinkley Point C site is being pushed from late 2025 to June 2026.

In addition, the project’s completion costs are now estimated to be in the range of £22 billion to £23 billion (about $30.2 billion to $31.5 billion), some £500 million (about $686 million) more than the 2019 estimate, EDF said, adding the caveat that these revisions assume an ability to begin a return to normal site conditions by the second quarter of 2021.
