Vogtle 3 Initial Criticality

In summary, Vogtle Unit 3, the first Westinghouse AP1000 in the US, safely reached initial criticality on March 6, 2023. This is a significant milestone in the startup testing sequence and marks the first time the nuclear reaction has been started inside the reactor. The reactor is now producing nuclear heat, which will be used to generate steam. Vogtle 3 was added to the list of active NPPs monitored by the US NRC on October 13, 2022, and had its upper internals installed on October 26-28, 2022. The head was also placed on the flange on October 29. The reactor is licensed to produce 3400 MWt and is

"March 6, 2023
Georgia Power today announced that Vogtle Unit 3 has safely reached initial criticality. Initial criticality is a key step during the startup testing sequence and demonstrates that -- for the first time -- operators have safely started the nuclear reaction inside the reactor. This means atoms are being split and nuclear heat is being made, which will be used to produce steam..."

EDIT: Note Vogtle 3 is the first Westinghouse AP1000 in the US. Several have been completed and are operating in China
