Why push materials to their breaking point?
Stephen Taller
We push materials to their breaking point for you.
Millions of Americans rely on nuclear energy. It provides 20 percent of electrical power in the United States—24 hours a day, 7 days a week, 365 days a year. To maintain this reliability, every material used in our reactors must work safely and efficiently.
I’m part of a team of world-class scientists, engineers, and technical professionals at Oak Ridge National Laboratory, testing and evaluating materials designed to thrive in one of the most complex environments on Earth. Nuclear reactors experience heavy stress loads, high temperatures, corrosive environments, and intense radiation fields. Combined, these forces can substantially impact the performance of cladding or other structural materials. We want to know where and under what conditions materials may fail to keep a reactor running safely and reliably.
