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.

Once cooled, this molten glass can trap radioactive waste for thousands of years.

Organic matter found in vast quantities in oxygen-starved floodplains would yield only minimal energy for hungry microorganisms, which spurn the meal, researchers show in a study in Nature Geoscience.
