Vogtle Unit 4 CA20 structural module under fabrication in the Module Assembly Building. Workers weld a section of the Unit 4 CA01 structural module. Inside the Module Assembly Building, work continues on the Unit 4 CA20 structural module. The Unit 4 turbine building continues to take shape. Close-up view of the Unit 4 turbine building. Another perspective of the Unit 4 turbine building. From left, construction continues on the Unit 3 turbine building, nuclear island and auxiliary building. Unit 4 CA05 module is 'rigged for lift' to the heavy lift derrick. Workers set rebar at the Vogtle 3 and 4 construction site. Construction continues at the Unit 3 nuclear island. A worker sets rebar at the Vogtle 3 and 4 consruction site. Safe work practices are the first priority for workers at Vogtle 3 and 4. At sunrise, the massive Unit 4 CA05 module is ready for the meticulous lifting and placement process. The heavy lift derrick moves the 90-ton CA05 module toward the Unit 4 containment building. Guided by the heavy lift derrick, the CA05 module nears the Unit 4 containment building. Only a few feet remain until the CA05 module is set inside the containment building. Workers precisely guide the CA05 module into place inside the Unit 4 containment building. The CA05 module is set inside the Unit 4 containment building. With the Unit 4 nuclear island in the foreground, construction continues on a containment ring and turbine vessel in the distance. A bird's-eye view of Unit 3. A look down into the Unit 3 nuclear island. A look down into the Unit 4 nuclear island. An aerial shot of the entire Vogtle 3 and 4 construction site, Unit 3 on the left and Unit 4 on the right. Workers prepare the KBO4 module prior to placement inside the Unit 4 auxiliary building. The KBO4 module, the first mechanical module to be installed in Unit 4’s nuclear island, is lifted into place. Designed to process and discharge waste gas, the KBO4 module is set inside the Unit 4 auxiliary building.
