Exploring oxidative pathways in nuclear fuel

Powerful atomic-resolution instruments and techniques at Pacific Northwest National Laboratory (PNNL) are revealing new information about the interaction of uranium dioxide (UO2) with water. These new insights will improve ...

France's global nuclear fusion device a puzzle of huge parts

A hugely ambitious project to replicate the energy of the sun is entering a critical phase, as scientists and technicians in southern France begin assembling giant parts of a nuclear fusion device, an international experiment ...

DY Centauri: Stellar evolution while you watch

In 1930, Dorrit Hoffleit reported that star number #4749 in the Harvard List of variables had faded four times between 1897 and 1929, and identified it as an R Coronae Borealis (RCB) variable. RCB stars are luminous low-mass ...

In the far future, the universe will be mostly invisible

If you look out on the sky on a nice clear dark night, you'll see thousands of intense points of light. Those stars are incredibly far away, but bright enough to be seen with the naked eye from that great distance—a considerable ...

Study reveals single-step strategy for recycling used nuclear fuel

A typical nuclear reactor uses only a small fraction of its fuel rod to produce power before the energy-generating reaction naturally terminates. What is left behind is an assortment of radioactive elements, including unused ...

Rad revelations: Future fuel designs from noble metals

Researchers at PNNL are removing a shroud of mystery surrounding the behavior of certain metal particles in nuclear fuel. The team's findings could improve future fuel designs for more efficient and safe production of nuclear ...
