A team of researchers is working to expand our uranium chemistry understanding using a surprising tool: lasers. This capability gives never-before-seen insight into uranium gas-phase oxidation during nuclear explosions.
The world’s largest scientific society honored Sue B. Clark, a PNNL and WSU chemist, for contributions toward resolving our legacy of radioactive waste, advancing nuclear safeguards, and developing landmark nuclear research capabilities.
PNNL Laboratory Director Steve Ashby attended an event marking the 20th anniversary of the Department of Energy’s National Nuclear Security Administration Nuclear Smuggling Detection and Deterrence program.
Researchers used novel methods to safely create and analyze plutonium samples. The approaches could prove influential in future studies of the radioactive material, benefitting research in legacy, national security and nuclear fuels.
A new capability at PNNL will be able to replicate how nations process plutonium. Researchers will process small amounts of plutonium which they will analyze, using nuclear forensics techniques, to discover signatures.
Pointing the finger at chemical criminals: Several scientists from PNNL and other institutions will discuss new methods and approaches at the American Chemical Society's national meeting in San Francisco April 2-6.
