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 signing last October of a bilateral agreement between the United States and Poland to cooperate on the latter’s civil nuclear power program appears to be bearing fruit. On March 15, following a meeting in Warsaw between Patrick Fragman, president and chief executive officer of Westinghouse Electric Company, and Piotr Naimski, Poland’s secretary of state for strategic energy infrastructure, Westinghouse announced its intention to invest in nuclear technologies in Poland.

The agreement, which entered into force earlier this month, calls for the United States and Poland to cooperate over the next 18 months on a report laying out a plan for implementing Poland’s nuclear power program, as well as potential financing arrangements. It also defines areas of U.S.-Polish cooperation for decades to come, including support for relevant business entities and government-led efforts ranging from regulation to research and training to supply chain development.

Southern Company subsidiary Georgia Power has announced the receipt of the initial shipment of nuclear fuel for Vogtle-3, characterizing the event as a “major step” for the two-unit nuclear expansion project currently under way at the Vogtle nuclear power plant near Waynesboro, Ga.

Next step: With the receipt of the first nuclear fuel assemblies, the project is now focused on one of the major milestones for Unit 3, hot functional testing, the last critical step before fuel load and, ultimately, in-service operation, Georgia Power said.

In October, Vogtle plant operator Southern Nuclear announced a readjustment of its July 2020 “aggressive site schedule” dates for Unit 3 hot functional testing, fuel load, and commercial operation. The dates were moved from October 2020, December 2020, and May 2021, respectively, to January 2021, April 2021, and the third quarter of 2021. Southern Nuclear said that hot functional testing could start as late as the end of March 2021 and fuel load as late as mid-year 2021 without jeopardizing Vogtle-3’s November 2021 regulatory approved in-service date.

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.

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.

A massive water tank has been placed atop the containment vessel and shield building roof at Vogtle-3, one of two AP1000 reactors currently under construction at Southern Company’s nuclear expansion project near Waynesboro, Ga. The installation represents the final module placement for the unit and marks the latest significant milestone to be reached at the Vogtle site.
