Georgia Power says Vogtle Unit 4 begins hot functional testing

Georgia Power announced that hot functional testing has begun for Vogtle Unit 4. Hot functional testing marks the last series of major tests underway for the new nuclear unit ahead of initial fuel load. The testing represents a significant step towards operations and providing customers with a reliable, carbon-free energy source for the next 60 to 80 years. Hot functional testing is conducted to verify the successful operation of reactor components and systems together and confirm the reactor is ready for fuel load. As part of the testing, the site team will begin running Unit 4 plant systems, without nuclear fuel in the reactor, and advance through the testing process towards reaching normal operating pressure and temperature. Vogtle Unit 4 is projected to enter service in late fourth quarter 2023 or first quarter 2024. Georgia Power is the largest electric subsidiary of Southern Company.
