The U.S. Nuclear Regulatory Commission, U.S. Army Corps of Engineers, and PNNL partnered to complete—in record time—an environmental impact statement for the nation’s first small modular nuclear reactor, to be sited at Clinch River, Tenn.

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.

Changes in water volume tend to be smaller in managed watersheds but occur earlier.

PNNL provides gateway to nuclear innovation for small business

PNNL is studying the movement of lamprey fish, which are culturally and historically important to the Pacific Northwest, on rivers and through hydroelectric dams.

Oil spills could be cleaned up in the icy, rough waters of the Arctic with a chemically modified sawdust material that absorbs up to five times its weight in oil and stays afloat for at least four months.
