During World War II, uranium for the atomic bomb was produced in this Tennessee city, which today is home of nuclear research facilities. A country music group named themselves after this city. What is it?

The Tennessee city described is Oak Ridge. During World War II, it was established as one of the three primary sites of the Manhattan Project, the top-secret initiative to develop the atomic bomb. This "secret city" rapidly grew from a quiet rural area into a bustling industrial complex, employing thousands of people who worked tirelessly to enrich uranium. Its existence was so clandestine that it didn't appear on maps, and many residents were unaware of the true nature of their work, only knowing they were contributing to the war effort.

Today, Oak Ridge continues its legacy as a center for scientific discovery and innovation. It is home to world-class nuclear research facilities, most notably the Oak Ridge National Laboratory (ORNL). ORNL is a multi-program science and technology national laboratory that conducts a wide range of basic and applied research for the U.S. Department of Energy, focusing on areas such as neutron science, high-performance computing, materials science, and nuclear energy. Its ongoing work addresses critical challenges in energy, security, and scientific exploration.

Adding another unique layer to its identity, the Grammy-winning country and gospel music group, The Oak Ridge Boys, adopted the city's name. While the group's origins trace back to Georgia, their association with the city further cemented Oak Ridge's place in both American history and popular culture, marking it as a city of profound scientific significance and unexpected musical fame.
