Since 1943, Oak Ridge National Laboratory has built 13 nuclear reactors — now it's preparing for its 14th, the Transformational Challenge Reactor, or TCR. But this one will be quite a departure from the reactors that have come before. It’s going to be 3D printed. TCR aims to revolutionize how a nuclear reactor is built – a process that hasn’t really changed much in the past 50 years. In this episode, you'll hear from some of the lab's nuclear and materials experts, an industry partner using technology coming out of TCR, as well as Rita Baranwal, the assistant secretary for the Office of Nuclear Energy in the U.S. Department of Energy.
