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.

Celebrating 80 Years: Meeting the Needs of a Changing World
In the first part of our 80th anniversary series, you heard how the Manhattan Project helped end World War II with the development and use of the world’s first nuclear weapons. The success of this top-secret endeavor ushered in a new era of nuclear science. The expertise used to build the atomic bombs was applied in peacetime to a range of nuclear-inspired research. This research would spawn significant advances in existing fields like chemistry and materials science, and establish completely new ones like neutron scattering and health physics. In this episode, we'll explore the lab's growth and evolution in the decades that followed the war.

Celebrating 80 Years: Top-Secret Science
Eighty years ago, the U.S. government embarked on a secret mission that would change the world. The Manhattan Project was a massive effort that resulted in the world’s first nuclear weapons and the end of World War II. But its legacy extends well beyond the war, as it laid the foundation for groundbreaking science for decades to come. Oak Ridge National Laboratory is one of the facilities born out of the Manhattan Project. Over the past 80 years, its mission has evolved and expanded to become a world leader in supercomputing, materials research, isotopes, clean energy — to name a few — but to this day is still strongly associated with its Manhattan Project roots. In this episode, you'll hear the story of the lab's top-secret origin from Alan Icenhour, the lab’s recently retired deputy for operations.

HFIR: Leading the World in Isotopes and Science
For nearly six decades, the High Flux Isotope Reactor, or HFIR, at Oak Ridge National Laboratory has been one of the world’s most powerful research reactors. It has played a critical role in making isotopes for a range of applications, including space exploration, periodic table discoveries and life-saving cancer treatments. However, isotope production isn't HFIR's only claim to fame. The versatile reactor boasts world-class capabilities for neutron scattering, materials testing and analyzing samples at the atomic scale. In this episode, you'll hear from the scientists and engineers who help carry out these missions and ensure the reactor will run for decades to come.

FRIB: Bringing Cosmic Elements to Earth
When the universe was formed billions and billions of years ago, the building blocks of life were forged with it. Hydrogen, carbon, iron, nitrogen, calcium, oxygen are just a few of the elements born from the cosmos that make up life on Earth. There are currently 118 known elements and we use the periodic table to organize and understand them. But straightforward as the periodic table seems, it contains a lot of mysteries. Scientists have catalogued more than 3,000 known isotopes and speculate there are thousands more yet to be discovered. The Facility for Rare Isotope Beams, also known as FRIB, has come online at Michigan State University to help researchers in their quest to create new isotopes and study their exotic behavior. FRIB has been years in the making. In fact, several of the instruments and detectors used originated from a historic facility at Oak Ridge National Laboratory. In this episode, you'll hear from several scientists who have been along for the journey about the history and future of this new facility – and what it means for science and society.
