Constellation Energy Corp., the biggest US operator of reactors, expects Three Mile Island to go back into service in 2028.

The Three Mile Island Nuclear plant, home of the worst nuclear accident in U.S. history, would restart under a deal in which Microsoft purchases all its power.

In a groundbreaking move, Microsoft and BlackRock are joining forces with a $30 billion investment over the next decade to drive advancements in artificial intelligence (AI). This massive investment not only highlights the growing significance of AI in global industries but also underscores the challenges of powering these cutting-edge systems.
