ORNL facility receives American Nuclear Society’s historic landmark designation


The American Nuclear Society has designated the Radiochemical Engineering Development Center at the Department of Energy’s Oak Ridge National Laboratory an ANS Nuclear Historic Landmark, recognizing more than 50 years of isotope production and nuclear fuel cycle research.

“This honor is particularly timely in the Lab’s 75th anniversary year, and it highlights a facility at the center of some of our most important work,” ORNL Director Thomas Zacharia said. “Nuclear research and the production of isotopes date to our very beginnings as a laboratory, and for the past half century, REDC has helped to make our engineers and scientists global leaders in isotope production and the advancement of nuclear science – leadership we will continue for the next 50 years and beyond.”

he designation by the American Nuclear Society identifies and memorializes sites or facilities whose outstanding physical accomplishments were instrumental in the advancement and implementation of nuclear technology and the peaceful uses of nuclear energy.

With a variety of hot cells, glove boxes and laboratories, REDC is used to perform research and development in areas such as energy, medicine, national security and space exploration. One current effort focuses on producing plutonium-238 for use in NASA’s future deep space missions, with the goal of full-scale production by 2025.

A long-standing mission of REDC has been the production of californium-252—a portable neutron source used in industry and for national security applications. ORNL is the only production site of Cf-252 in the western world. In addition, REDC was critical in the production of berkelium-249 used in the physics experiments that resulted in the discovery of element 117, tennessine.

REDC’s unique design conveniently provides the ability to add and replace specialized modular equipment. This design not only has been valuable in isotope production but also has enabled REDC to serve the nation through research, development and demonstration of advanced nuclear fuel cycle processes for DOE’s Office of Nuclear Energy.

This capability enabled the facility to process irradiated fuels from commercial nuclear reactors and the Fast Flux Test Facility, a liquid metal fast breeder reactor, making REDC a vital component of the Consolidated Fuel Recycle Program, the Advanced Fuel Cycle Initiative, the Global Nuclear Energy Partnership and the Fuel Cycle Technologies program over the last 40 years.

REDC joins the Graphite Reactor, Tower Shielding Reactor, Oak Ridge Electron Linear Accelerator, Molten Salt Reactor Experiment, Radiochemical Processing Plant, and HFIR as ANS Nuclear Historic Landmarks at ORNL.
