Nuclear Stocks Are Soaring. We Size Up the Prospects for 3 New Ones.

More than 80 companies around the world are developing new kinds of nuclear reactors, hoping to get their hands on the tens of billions of dollars that utilities are expected to spend on reactors in the coming decade.

The three are entering public markets at a time of enormous enthusiasm for new nuclear technologies, which are seen as one solution to the growing electricity demand from artificial-intelligence data centers and other industrial plants.
