The U.S. nuclear energy sector is going through one of the most innovative and transformative times in its history.

An entirely new class of advanced reactors will soon be coming in a wide variety of sizes and applications.

More than 20 U.S. companies are working on designs that are smaller, scalable, versatile and even mobile—providing far greater access to nuclear power than ever before.

Microreactors will likely be the first advanced reactors to enter the U.S. market. Domestic reactor developers are currently working on gas and heat pipe-cooled designs that could debut by the mid-2020s.
