Electrokinetic remediation (TRANSCEND)
Electrokinetic remediation (EKR; simply put, moving things with electricity) uses low voltage DC current to control the migration (Figure 1) of contaminants in porous media and remove or degrade them. We have previously demonstrated that ex-situ EK techniques can treat plutonium-contaminated wastes at the AWE Aldermaston site1, and the technique is widely applied at scale for the destruction of substrates (soils, etc.) contaminated with organic pollution.
Here, we present our work on using EKR to remediate a range of contaminated substrates, including 137Cs contaminated Fukushima simulants, Pu/Am-contaminated AWE soils, and ongoing work, in controlled colloid flow (w/ Prof. Becky Lunn, Strathclyde), and remediation of real Sellafield materials by controlled growth of in-situ iron barriering. We discuss our research to date and future directions to explore, with a particular focus on the remediation of soils contaminated with 60Co, 90Sr, 99mTc, 134/137Cs, 233/235/238U and transuranics, applied at scale and in-situ on working nuclear sites.

Abstract
Electrokinetic remediation (EKR; simply put, moving things with electricity) uses low voltage DC current to control the migration (Figure 1) of contaminants in porous media and remove or degrade them. We have previously demonstrated that ex-situ EK techniques can treat plutonium-contaminated wastes at the AWE Aldermaston site1, and the technique is widely applied at scale for the destruction of substrates (soils, etc.) contaminated with organic pollution.
Here, we present our work on using EKR to remediate a range of contaminated substrates, including 137Cs contaminated Fukushima simulants, Pu/Am-contaminated AWE soils, and ongoing work, in controlled colloid flow (w/ Prof. Becky Lunn, Strathclyde), and remediation of real Sellafield materials by controlled growth of in-situ iron barriering. We discuss our research to date and future directions to explore, with a particular focus on the remediation of soils contaminated with 60Co, 90Sr, 99mTc, 134/137Cs, 233/235/238U and transuranics, applied at scale and in-situ on working nuclear sites.
