Unit 3 at Pakistan’s Karachi nuclear power plant has been connected to the national grid, China National Nuclear Corporation (CNNC) announced on March 4, making it the second Hualong One reactor outside of China to have reached the last major step prior to commercial operation. (The distinction of being the first belongs to Unit 3’s twin, Karachi-2, which was connected to the grid in March 2021 and entered commercial operation in May.)

Karachi-3 had achieved criticality on February 21 after completing hot functional testing and entering the fuel loading stage last November.

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.

The Emirates Nuclear Energy Corporation has announced the startup of Unit 2 at the Barakah nuclear power plant, located in the Al Dhafra region of Abu Dhabi, the United Arab Emirates’ capital city.

The milestone, ENEC noted in its August 27 announcement, was achieved approximately one year after the startup of the plant’s Unit 1 reactor and within five months of Unit 1’s entering commercial operation.

Vogtle project suffers another setback

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.

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.

More adjustments to Vogtle milestone dates likely

Largely as a result of the continuing COVID-19 crisis, the Vogtle reactor-construction project team expects to further adjust dates for achieving key project milestones, including the start of hot functional testing and fuel load for Unit 3, Southern Company subsidiary Georgia Power announced on January 11.

The company added, however, that it continues to expect to bring Unit 3 into service this November and Unit 4 into service in November 2022. Additional updates on the project will be provided during Southern’s quarterly earnings call next month.

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.

In testimony filed last week with the Georgia Public Service Commission, Georgia Power and Southern Nuclear acknowledge that the “aggressive” target dates set in July for some of the Vogtle construction project’s upcoming milestones have had to be pushed back by a few months. At the same time, however, the companies continue to express confidence in being able to meet the regulatory-approved commercial start dates for the new reactors—November 2021 for Unit 3 and November 2022 for Unit 4.

The testimony was filed in support of Georgia Power’s Twenty-third Semi-annual Vogtle Construction Monitoring Report, released in August, which covers the period from January 1 to June 30, 2020.

Major milestone reached at Vogtle-3

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.

Cold hydro testing of Unit 3 confirmed that the reactor’s coolant system functions as designed and verified that the welds, joints, pipes, and other components of the coolant system and associated high-pressure systems do not leak when under pressure, Georgia Power said. The company also noted that it expects to meet the regulatory-approved in-service dates for the new reactors: November 2021 for Unit 3, and November 2022 for Unit 4.
