<tbody><tr><td><p>ATLANTA --&nbsp;Georgia Power announced today that the second steam generator has been safely placed for Unit 3 at the Vogtle nuclear expansion near&nbsp;Waynesboro, Georgia. The 1.4 million-pound steam generator was lifted into the Unit 3 nuclear island on Tuesday and positioned adjacent to the unit&#39;s other steam generator, which was placed in August. With the completion of this week&#39;s lift, both steam generators are now in place for the new unit.&nbsp; &nbsp;</p>
<p>Steam generators, measuring nearly 80 feet long, are heat exchangers used to convert water into steam using the heat produced in a nuclear reactor core. Each new AP1000 unit at Plant Vogtle requires two steam generators, all of which are currently onsite. The steam generators for the new units were fabricated in&nbsp;South Korea&nbsp;and transported to the site via the Port of&nbsp;Savannah&nbsp;and then via rail.</p>
<p>Since Southern Nuclear, the Southern Company subsidiary which operates the existing units at Plant Vogtle, assumed control of the site from Westinghouse this summer, momentum has accelerated with a focus on increased productivity and safe, high-quality construction. Other major milestones achieved in recent weeks include a critical concrete &#39;super placement&#39; for Unit 3 and the lift of the 237-ton CA03 module for Unit 4.&nbsp; The 71-hour continuous concrete placement included 1,844 cubic yards of concrete – enough to create a sidewalk more than six miles long.&nbsp; The Unit 4 CA03 module is a critical component and 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.</p>
<p>More than 6,000 workers from across the country are on-site at Plant Vogtle today working to complete the nation&#39;s first new nuclear units in 30 years. New photos of progress at the construction site are available each month in the&nbsp;<a href="">Plant Vogtle 3 &amp; 4 Online Photo Gallery</a>.</p>
