Vogtle-4 hits start-up milestone

Georgia Power’s Vogtle-4, located near Waynesboro, Ga., reached initial criticality this week, hitting a major milestone in the start-up of the reactor.
The company announced the news on February 14. Initial criticality demonstrates that operators have safely started the nuclear reactor, or, in other words, the fission reaction within the unit is now self-sustaining and the nuclear reactor is ready to produce heat.
