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.

For the first time, researchers have created a gram of yellowcake — a powdered form of uranium used to produce fuel for nuclear power production — using modified acrylic fibers to extract it from seawater.

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

PNNL researchers report in the journal Chem, that inexpensive materials called metal-organic frameworks have been very successful in separating xenon.

This time of year finds many of us busy with holiday shopping. While PNNL might not be developing the latest video games or hoverboards, we are working hard to deliver a few presents you might like.

Radiochemical Processing Laboratory: Now a nuclear historic landmark.

Six energy technologies that do everything from protect fish to monitor the health of flow batteries are getting a boost at PNNL with support from DOE's Technology Commercialization Fund.

If the frequency of droughts increases, the time between droughts likely won't be long enough for trees to recover.

PNNL's ThermalTracker software analyzes video with night vision, the same technology that helps soldiers see in the dark, to help offshore wind power be bird- and bat-friendly.
