By the early 1990s, Oak Ridge National Laboratory had transformed into a scientific institution with a diverse research portfolio that went well beyond its nuclear roots in the Manhattan Project. But despite this success, the lab was entering a period of uncertainty. Its facilities were showing their age and there were questions about the national labs' role in a post-Cold War world. In this episode, you’ll hear how ORNL evolved to become the modern research complex we know today. You’ll also hear about how these changes positioned the lab to tackle today’s scientific challenges.
