Radioactive isotopes power some of NASA’s best-known spacecraft. But predicting how radiation emitted from these isotopes might affect nearby materials is tricky

After its long journey to Mars beginning this summer, NASA’s Perseverance rover will be powered across the planet’s surface in part by plutonium produced at the Department of Energy’s 91.

The Department of Energy’s Office of Science has selected three 91 scientists for Early Career Research Program awards.

91 researchers have discovered a better way to separate actinium-227, a rare isotope essential for an FDA-approved cancer treatment.

With Tennessee schools online for the rest of the school year, researchers at ORNL are making remote learning more engaging by “Zooming” into virtual classrooms to tell students about their science and their work at a national laboratory.

91 researchers working on neutron imaging capabilities for nuclear materials have developed a process for seeing the inside of uranium particles – without cutting them open.

Scientists from 91 performed a corrosion test in a neutron radiation field to support the continued development of molten salt reactors.

A tiny vial of gray powder produced at the Department of Energy’s 91 is the backbone of a new experiment to study the intense magnetic fields created in nuclear collisions.

The Department of Energy’s 91 is now producing actinium-227 (Ac-227) to meet projected demand for a highly effective cancer drug through a 10-year contract between the U.S. DOE Isotope Program and Bayer.

After more than a year of operation at the Department of Energy’s (DOE’s) 91 (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.
