Initially, Kevin Gaddis’s adapted HPIC will be used only for the fourth of six separations in  actinium-225 processing, but he hopes it will later be used for other separations — and other isotopes. Credit: Carlos Jones/ORNL, U.S. Dept. of Energy

An Oak Ridge National Laboratory researcher has invented a version of an isotope-separating device that can withstand extreme environments, including radiation and chemical solvents.

For the first time in 25 years, scientists will use deuterium and tritium to create a plasma inside the chamber of the Joint European Torus in the United Kingdom to study nuclear fusion. As in the earlier experiments, diagnostics systems developed by ORNL will play a key role in monitoring the plasma. Credit: EUROfusion

Equipment and expertise from Oak Ridge National Laboratory will allow scientists studying fusion energy and technologies to acquire crucial data during landmark fusion experiments in Europe.

Scientists at Oak Ridge National Laboratory have devised a method to identify the unique chemical makeup of every lithium-ion battery around the world, information that could accelerate recycling, recover critical materials and resolve a growing waste stream.

ORNL welder Devin Johnson uses a new orbital welder to seal a hollow target in a glovebox in the lab’s Radiochemical Engineering Development Center. The new welder makes a clean seam on the metal target, eliminating the need for hand-finishing afterward. Credit: Carlos Jones/ORNL, U.S. Dept. of Energy

A better way of welding targets for Oak Ridge National Laboratory’s plutonium-238 production has sped up the process and improved consistency and efficiency. This advancement will ultimately benefit the lab’s goal to make enough Pu-238 – the isotope that powers NASA’s deep space missions – to yield 1.5 kilograms of plutonium oxide annually by 2026.
