DESCRIPTION
The Current State of Cementitious and Ambient Temperature Immobilization Processes in Nuclear Waste Management
Cementation and other ambient temperature solidification processes play a crucial role in solving global needs in nuclear waste management and disposal. While these materials are well studied across multiple industries, recent advancements in formulation development, testing methods, characterization techniques, modeling capabilities and production processes have presented ample opportunities for enhancing the implementation of cementitious and ambient temperature processes within this sector. This presentation will provide an overview of R&D activities around the use of cementitious and ambient temperature solidification processes for nuclear waste performed at Pacific Northwest National Laboratory. Including designing formulations for specific waste streams (e.g., cement based, geopolymers), linking chemo-mechanical properties, further mechanistic understandings using advanced characterization, long-term and field testing, and modeling approaches for long-term disposal behavior.
BIOGRAPHY
Matthew Asmussen, Chemist, Pacific Northwest National Laboratory
Matthew Asmussen is a chemist in the Radiological Materials group at Pacific Northwest National Laboratory (PNNL). He joined PNNL in October 2014 after receiving his PhD in chemistry from the University of Western Ontario (Canada). His primary research interests are in nuclear waste form development, durability, disposal, and modeling; cementitious, glass, ceramic, and metallic waste forms; radionuclide remediation technologies; nuclear waste canister corrosion (e.g., used fuel, krypton) repository sciences; radioiodine behavior, capture, and disposal; power-to-product conversion processes; electrochemical seawater conversions (e.g., lithium, electrolysis, and electrofuels); and corrosion science and geological carbon dioxide sequestration. He also has experience and has published works related to corrosion, fuel cells, solar cells, nanomaterial synthesis, wastewater treatment, lightweight alloys, and nuclear waste management and policy. Since 2018, Asmussen has served as principal investigator of PNNL’s Integrated Disposal Facility Performance Assessment program, supporting the development, testing, disposal, and modeling of low-level/low-activity waste forms for the Hanford Site. Dr. Asmussen has also served as an expert on waste form behavior supporting review teams at the Hanford Site, the National Academy of Sciences, and the International Atomic Energy Agency. In his spare time, he enjoys family time, playing hockey, biking, spending time at the lake, and cooking.
