Peering through the thick, green glass of a decades-old "hot cell," an expert technician manipulates robotic arms to study highly radioactive waste from Hanford, in support of ongoing cleanup.

Vitrifying nuclear waste for storage is complicated by aluminum and understanding this behavior is vital. Research suggests that upon radiolysis, the properties of humid aluminum particles do not change substantially but hydrogen is formed.

While some of us may periodically ponder the universe, most of us don't dedicate our lives to studying its mysteries, including its birth, evolution and fate.

Low-activity waste from Hanford tank vitrified for first time in a continuous process at PNNL.

DOE gives go ahead for SuperCDMS — one of the world's most sensitive dark matter experiments.

PNNL and WSU team on research to handle waste streams from biofuel production.

Scientists detect phenomenon in lab that occurs during neutron star formation and supernovae explosions.

To study some of the tiniest particles in the universe, an international band of physicists is building a massive instrument to look for signs of particles predicted to be fundamental to the workings of the universe.

The search for dark matter called spin-dependent WIMPS is on — in an underground lab in Canada
