The Hanford Site is now immobilizing radioactive waste in glass: a process known as vitrification. PNNL contributed 60 years of materials science expertise—and is providing operational support—to help the nation meet this cleanup milestone.

Mystery of how important aluminum minerals form and dissolve solved with materials science and advanced imaging studies.

PNNL brings its expertise to the space domain by joining an organization that facilitates collaboration across the global space industry.

Researchers have begun a series of experiments that could bring about more energy for grid, thanks to a special delivery of 11 "high burnup" rods.

A launch from Cape Canaveral early today carried a PNNL experiment to space so scientists can learn more about radiation far above Earth.

Three PNNL technologies have been named 2024 R&D 100 Award winners.

Complex metal alloys enter a new era of predictive design for aerospace and other high-temperature applications.

Scientists stop the motion of atoms to watch electrons move in liquid water.

Ancient seawater pockets offer a new source of clues to climate change in vanished oceans and our own.

Three unused, 48,000-pound stainless steel canisters arrived at PNNL, bringing the chance to deepen research in spent nuclear fuel storage and transportation.

Researchers at the Department of Energy’s Pacific Northwest National Laboratory and Sandia National Laboratories have joined forces to reduce costs and improve the reliability of hydrogen fueling stations.
