Historical operations at nuclear mega-facilities such as Hanford, USA, and Sellafield, UK
have led to a legacy of radioactivity-contaminated land. Calcium phosphate phases (eg …

A growing body of research supports widespread future reliance on apatite for radioactive
waste cleanup. Apatite is a multi-functional radionuclide sorbent that lowers dissolved …

A major issue with in situ subsurface remediation is the ability to achieve an even spatial
distribution of remedial amendments to the contamination zones in an aquifer or vadose …

Groundwater at legacy nuclear facilities around the world is contaminated with radionuclides
including strontium-90 and technetium-99, which are often present as co-contaminants …

This study shows that acidic and alkaline wastes co-disposed with uranium into subsurface
sediments have significant impact on changes in uranium retardation, concentration, and …

An injectable permeable reactive barrier (PRB) technology was developed to sequester
90Sr in groundwater through the in situ formation of calcium‐phosphate mineral phases …

The reaction of acidic radioactive waste with sediments can induce mineral transformation
reactions that, in turn, control contaminant fate. Here, sediment weathering by synthetic …

Abstract 60+ Years of nuclear power generation has led to a significant legacy of
radioactively contaminated land at a number of nuclear licenced" mega sites" around the …

Radioactive contaminants, including uranium, strontium-90 and technetium-99 are present
at elevated concentrations within groundwaters at several nuclear facilities around the world …

An in-situ permeable reactive barrier (PRB) is being used to remove strontium-90 from
groundwater along the 100-N Area shoreline at the US Department of Energy Hanford Site …
