Uranium diffusion in responsive decontaminating coatings

CHED 863

Luke Potts, H. Neil Gray, and Brian K. Taylor.
Previously we have reported our success in the development of strippable decontaminating coatings for the detection and removal of uranium and plutonium from contaminated surfaces. We will report our continued progress on the design and development of contaminant-sensing, decontaminating coatings as tools for the decontamination of fouled surfaces. Specifically our recent progress regarding the diffusion of uranium from surfaces into novel responsive decontaminating coatings will be presented. Coating samples applied to uranium contaminated surfaces were flash frozen using liquid nitrogen at various times after initial application. After removal of the frozen coating, the surfaces were analyzed using scintillation counting. Subsequent data treatment and analysis provided some insight into the diffusion process over the decontamination period.
