Meet the director: Ken Andersen

DOE/US Department of Energy

Ken Andersen is the associate laboratory director of the Spallation Neutron Source and the High Flux Isotope Reactor in Oak Ridge, Tennessee. This is a continuing profile series on the directors of the Department of Energy (DOE) Office of Science user facilities. These scientists lead a variety of research institutions that provide researchers with the most advanced tools of modern science.

US researchers simulate compact fusion power plant concept

DOE/US Department of Energy

The Compact Advanced Tokamak (CAT) concept uses physics models to show that by carefully shaping the plasma and the distribution of current in the plasma, fusion plant operators can suppress turbulent eddies in the plasma. This would reduce heat loss and allow more efficient reactor operation. This advance could help achieve self-sustaining plasma and smaller, less expensive power plants.

Enclosing radiation-loaded particles to better seek and destroy cancer

DOE/US Department of Energy

When medical isotopes are used to treat diseases, they emit large amounts of energy that makes it hard to keep them near the target cells. Researchers are now testing a way to enclose isotopes in tiny pieces of biodegradable material that will keep the isotopes at treatment sites, ensuring that their energy can kill diseased cells with little effect on surrounding cells.

Keeping waste where it belongs: Grain size explains how spent nuclear fuel enters the environment

DOE/US Department of Energy

When compounds in spent nuclear fuel break down, they can release radioactive elements into the ground and water. Scientists know that one fuel compound, neptunium dioxide, reacts with water, but they do not fully understand the process. This new study found that neptunium tends to dissolve where grains of the material come together, and larger grains are less likely to dissolve.

Department of Energy invests $1 million in artificial intelligence research for privacy-sensitive datasets

DOE/US Department of Energy
Business Announcement

The U.S. Department of Energy (DOE) announced $1 million for a one-year collaborative research project to develop artificial intelligence (AI) and machine learning (ML) algorithms for biomedical, personal healthcare, or other privacy-sensitive datasets.

Anže Slosar: Then and Now; 2011 Early Career Award Winner

DOE/US Department of Energy

To map the structures in the universe, Anže Slosar scaled up Baryon Oscillation Spectroscopic Survey data. He uses light from very distant cosmic objects called quasars as a backlight to illuminate the structure in the universe in front of them.

Imposing Chaos on Magnetic Fields Suppresses Runaway Electrons in a Fusion Plasma

DOE/US Department of Energy

Researchers are using smaller tokamaks and computer models to test approaches for suppressing runaway electrons. This research used measurements and modeling to demonstrate that perturbations to the magnetic field in a tokamak fusion plasma can suppress high-energy runaway electrons. The results could help improve the operation of ITER and other future fusion devices.

Department of Energy invests $16 million in data-intensive scientific machine learning research and analysis

DOE/US Department of Energy
Grant and Award Announcement

The U.S. Department of Energy (DOE) announced $16 million for five collaborative research projects to develop artificial intelligence (AI) and machine learning (ML) algorithms for enabling scientific insights and discoveries from data generated by computational simulations, experiments, and observations.
