The Vogtle nuclear expansion project reached several construction milestones recently.
The 1.4 million-pound, 80 feet long steam generator was placed for unit 3. Steam generators, are heat exchangers used to convert water into steam using the heat produced in a nuclear reactor core. The first one was successfully placed in August of this year
The lift of unit 4’s 234-ton CA03 module. The CA03 module is a critical part of the In-Containment Refueling Water Storage Tank (IRWST). The IRWST is a 75,300-cubic foot tank that, once the units are operational, is filled with borated water and provides passive heatsink within containment and backup cooling for the reactor vessel.
Concrete placement of 1,844 cubic yard of concrete that took 71 continuous hours. The concrete was poured into four areas of the unit 3 containment vessel- the refueling cavity, the bottom of the in-containment refueling water storage tank, the west steam generator cubicle walls, and the pressurizer cubicle walls.
