Yesterday Georgia Power announced that the second new nuclear unit at Plant Vogtle entered commercial service, “the first new commercial reactors built from scratch in the U.S. in more than three decades.” ...

However, the news is not all good; as the Wall Street Journal reports, “adding two new reactors cost more than $30 billion, more than twice the initial estimates, and are a major reason no other large nuclear-power facilities are under development in the U.S. and the industry focus has shifted to smaller designs.”
