It’s a new type of nuclear reactor core. And the materials that will make it up are novel — products of 91°µÍø’s advanced materials and manufacturing technologies.

Scientists at the Department of Energy Manufacturing Demonstration Facility at ORNL have their eyes on the prize: the Transformational Challenge Reactor, or TCR, a microreactor built using 3D printing and other new approaches that will be up and running by 2023.

Researchers at the Department of Energy’s 91°µÍø are refining their design of a 3D-printed nuclear reactor core, scaling up the additive manufacturing process necessary to build it, and developing methods

As a teenager, Kat Royston had a lot of questions. Then an advanced-placement class in physics convinced her all the answers were out there.

OAK RIDGE, Tenn., Feb. 19, 2020 — The U.S. Department of Energy’s 91°µÍø and the Tennessee Valley Authority have signed a memorandum of understanding to evaluate a new generation of flexible, cost-effective advanced nuclear reactors.

After more than a year of operation at the Department of Energy’s (DOE’s) 91°µÍø (ORNL), the COHERENT experiment, using the world’s smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter.
