Vogtle Unit 4 shield building roof set
Building provides protection for the containment vessel that houses the reactor
Hot Functional Testing last major test remaining for Unit 3 ahead of fuel load
ATLANTA, Dec. 11, 2020 /PRNewswire/ -- The two-million-pound roof of the Vogtle Unit 4 shield building has been set into place at Georgia Power's nuclear expansion project near Waynesboro, Georgia. With this placement, there is now one last major crane lift remaining for Vogtle Unit 4, the CB-20 module, which is part of the AP1000 reactor's advanced passive safety system.
The Vogtle Unit 4 shield building roof placement comes just days after the receipt of the first nuclear fuel shipment for Vogtle Unit 3, representing the first nuclear fuel shipment for the AP1000 reactor in the U.S.
With the receipt of the first nuclear fuel assemblies, the site is preparing for the last major test remaining for Unit 3, hot functional testing, ahead of initial fuel load. This series of tests is the last critical step before fuel load and ultimately in-service operation for Unit 3.
The Unit 4 shield building roof measures 135 feet in diameter, 37 feet tall and weighs more than two fully-loaded jumbo jets. This placement follows the setting of the Unit 4 containment vessel top from earlier this year. The shield building is a unique feature of the AP1000 reactor design for Vogtle 3 & 4, providing an additional layer of safety around the containment vessel and nuclear reactor to protect the structure from any potential impacts.
2020 Milestones Achieved
With more than 7,000 workers on site, and more than 800 permanent jobs available once the units begin operating, Vogtle 3 & 4 is currently the largest jobs-producing construction project in the state of Georgia.

Cautionary Note Regarding Forward-Looking Statements
Certain information contained in this release is forward-looking information based on current expectations and plans that involve risks and uncertainties. Forward-looking information includes, among other things, statements concerning the expected schedule for completion of construction and start-up of Plant Vogtle units 3 and 4, and expected job creation. Georgia Power cautions that there are certain factors that can cause actual results to differ materially from the forward-looking information that has been provided. The reader is cautioned not to put undue reliance on this forward-looking information, which is not a guarantee of future performance and is subject to a number of uncertainties and other factors, many of which are outside the control of Georgia Power; accordingly, there can be no assurance that such suggested results will be realized. The following factors, in addition to those discussed in Georgia Power's Annual Report on Form 10-K for the year ended December 31, 2019, Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020, June 30, 2020, and September 30, 2020, and subsequent securities filings, could cause actual results to differ materially from management expectations as suggested by such forward-looking information: the potential effects of the continued COVID-19 pandemic, including, but not limited to, extended disruptions to supply chains and further reduced labor availability and productivity, which could have a variety of adverse impacts, including a negative impact on the ability to develop, construct, and operate facilities, including, but not limited to, Plant Vogtle Units 3 and 4; the ability to control costs and avoid cost and schedule overruns during the development, construction, and operation of facilities or other projects, including Plant Vogtle Units 3 and 4, which includes components based on new technology that only within the last few years began initial operation in the global nuclear industry at this scale, and including changes in labor costs, availability and productivity, challenges with management of contractors or vendors, subcontractor performance, adverse weather conditions, shortages, delays, increased costs, or inconsistent quality of equipment, materials, and labor, contractor or supplier delay, delays due to judicial or regulatory action, nonperformance under construction, operating, or other agreements, operational readiness, including specialized operator training and required site safety programs, engineering or design problems, design and other licensing-based compliance matters, including, for nuclear units, the timely submittal by Southern Nuclear of the Inspections, Tests, Analyses, and Acceptance Criteria documentation for each unit and the related reviews and approvals by the NRC necessary to support NRC authorization to load fuel, challenges with start-up activities, including major equipment failure, or system integration, and/or operational performance; the ability to overcome or mitigate the current challenges at Plant Vogtle Units 3 and 4, including, but not limited to, those related to COVID-19, that could further impact the cost and schedule for the project; legal proceedings and regulatory approvals and actions related to construction projects, such as Plant Vogtle Units 3 and 4, including Public Service Commission approvals and NRC actions; under certain specified circumstances, a decision by holders of more than 10% of the ownership interests of Plant Vogtle Units 3 and 4 not to proceed with construction and the ability of other Vogtle owners to tender a portion of their ownership interests to Georgia Power following certain construction cost increases; the ability to construct facilities in accordance with the requirements of permits and licenses (including satisfaction of NRC requirements), to satisfy any environmental performance standards and the requirements of tax credits and other incentives, and to integrate facilities into the Southern Company system upon completion of construction; the inherent risks involved in operating and constructing nuclear generating facilities; the ability of counterparties of Georgia Power to make payments as and when due and to perform as required; the direct or indirect effect on Georgia Power's business resulting from cyber intrusion or physical attack and the threat of physical attacks; catastrophic events such as fires, earthquakes, explosions, floods, tornadoes, hurricanes and other storms, droughts, pandemic health events or other similar occurrences; and the direct or indirect effects on Georgia Power's business resulting from incidents affecting the U.S. electric grid or operation of generating or storage resources.
