The components placed are the stator assembly and the deaerator. The stator assembly, which includes the stator and the stator housing, weighs more than 460 tons. It was built in Japan and represents two of the four major subcomponents of the main generator. The main generator for Plant Vogtle 3 will have a total energy output of 1,117 MW. The stator is a stationary component of the main generator that works together with the rotor and exciter to generate electricity.
The 303-ton deaerator was developed in South Korea and is nearly 145 feet long and approximately 20 feet high. It serves as a purification system for feedwater, removing minerals and other deposits, reducing plant maintenance and operating costs and preventing corrosion. Both pieces were lifted into place by the heavy lift derrick.
Other major construction milestones include the safe placement of six new shield building panels for Unit 3, delivery of the first eight reactor coolant pumps and continued progress on the Unit 4 cooling tower, which is nearing a completed height of 601 feet. The units are scheduled to begin operations in 2019 and 2020.
