Latest Patents

One of Jung's latest patents is a chemical decontamination method that utilizes a chelate-free chemical decontamination reagent. This method is designed for the removal of dense radioactive oxide layers on metal surfaces. The reagent comprises a reducing agent, a reductive metal ion, and an inorganic acid, which effectively dissolves the radioactive oxide layer at relatively low temperatures. This process is not only efficient but also cost-effective, minimizing the time and resources required for decontamination. Importantly, the method avoids the use of conventional organic chelating agents, allowing for easier decomposition of residuals with an oxidizing agent, thus reducing secondary waste.

Another significant patent involves a decontamination method that targets radioactive contaminated metals or alloys. This method employs a chemical decontamination agent containing sulfuric acid and facilitates the formation of barium or strontium precipitates by adding specific cations and anions to the decontamination wastewater. This innovative approach further enhances the effectiveness of radioactive waste management.
