Excellence in Science & Technology

Mastering Phenomena Associated
with Radioactive and Irradiated Materials

2025 Vision: A decade of rapid advances in understanding the behavior of radioactive
materials has hastened the processing and safe storage of U.S. radioactive waste stock-
piles, and deterred would-be proliferators by developing predictive identifiers of
nuclear processing.

Goals PNNL’s Radiochemical Processing Laboratory is a vital
resource for addressing Hanford tank waste, subsurface
• Direct and control chemical reactivity contamination, and other environmental challenges. A
in radioactive materials and radiation Hazard Category II Non-Reactor Nuclear Facility, RPL's
environments capabilities are used to develop, test, and implement
processes for environmental cleanup and other needs.
• Harness radiation-induced interfacial
processes to create smart, sustain-
able new technologies

• Understand microstructural evolution
in response to irradiation and radio-
active environments

Research Partners

“With support from DOE’s Office of Science, Office of Tony Peurrung
Environmental Management, and the National Nuclear Steward
Security Administration, PNNL is moving the field from Sue Clark
empirically driven approaches to scientifically driven
development, dramatically expanding the range of Science Lead
solutions we can deploy to address the nation’s environ-
mental stewardship and non-proliferation challenges.
With research centers like the Interfacial Dynamics in
Radiation Environments and Materials, PNNL is
in a strong position to lead this transition. In fact,
if we do not, no one else will.”
