Explainable artificial intelligence—understanding and explaining the reasoning behind AI decisions—is a necessity for national security.

Explainable AI helps scientists understand and untangle the threads of information that the system uses to make choices or recommendations.

Ultra-trace radiation detection technique sets new global standard for measuring the nearly immeasurable.

A recent edition of the Infrastructure Resilience Research Group Journal featured an article written by PNNL researchers Rob Siefken and Jake Burns about “Design Basis Threat and the Low Threat Environment.”

As a physicist at PNNL, Jon Burnett’s work is about developing instruments to detect ultra-trace radionuclide signatures, analyze samples from around the world to look for evidence of nuclear explosions, and then interpret that information.

Despite the challenges, the talented and dedicated staff at Pacific Northwest National Laboratory kept delivering for the nation.

Quantum computing experts gather in the Pacific Northwest to discuss challenges and progress.

Researchers apply numerical simulations to understand more about a sturdy material and how its basic structure responds to and resists radiation. The outcomes could help guide development of the resilient materials of the future.

PNNL scientists served as lead guest editors for a special issue of the Journal of Applied Radiation and Isotopes.

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

April 26 marks the 31st anniversary of the explosion at the Chernobyl Nuclear Power Plant's Unit 4 reactor. Battelle researchers at PNNL were involved in an international consortium to look at long-term safety and containment of Unit 4. T
