One of the new nuclear generating units at Plant Vogtle has achieved first criticality. After nearly a decade and a half and tens of billions of dollars, Unit 3 is finally near to going into operation. This is good news for Georgia Power and their customers, but bad news for those of us who were hoping for a nuclear renaissance. The Vogtle units have taken way too long to build and have cost way too much money. If large nuclear units are to be part of the nuclear mix going forward that has to change.
