SEVERAL UNIVERSITIES TO EXPERIMENT WITH MICRO NUCLEAR POWER

If your image of nuclear power is giant, cylindrical concrete cooling towers pouring out steam on a site that takes up hundreds of acres of land, soon there will be an alternative: tiny nuclear reactors that produce only onehundredth the electricity and can even be delivered on a truck.

Small but meaningful amounts of electricity — nearly enough to run a small campus, a hospital or a military complex, for example — will pulse from a new generation of micronuclear reactors. Now, some universities are taking interest.

“What we see is these advanced reactor technologies having a real future in decarbonizing the energy landscape in the U.S. and around the world,” said Caleb Brooks, a nuclear engineering professor at the University of Illinois at Urbana-Champaign.

The tiny reactors carry some of the same challenges as large-scale nuclear, such as how to dispose of radioactive waste and how to make sure they are secure. Supporters say those issues can be managed and the benefits outweigh any risks.

Universities are interested in the technology not just to power their buildings but to see how far it can go in replacing the coal and gas-fired energy that causes climate change. The University of Illinois hopes to advance the technology as part of a clean energy future, Brooks said. The school plans to apply for a construction permit for a high-temperature, gas-cooled reactor developed by the Ultra Safe Nuclear Corporation, and aims to start operating it by early 2028. Brooks is the project lead.

Microreactors will be “transformative” because they can be built in factories and hooked up on-site in a plug-and-play way, said Jacopo Buongiorno, professor of nuclear science and engineering at the Massachusetts Institute of Technology. Buongiorno studies the role of nuclear energy in a clean energy world.

“That’s what we want to see, nuclear energy on demand as a product, not as a big mega project,” he said.
