Outline of Final Research Achievements

An applicability of pulsed power discharge as a decontamination method by separating contaminated matrix from uncontaminated coarse aggregate was examined. In this study, a stable cesium (Cs) isotope was used to simulate radioactively contaminated concrete. As a result, while the volume of reclaimed aggregate from concrete reproduced by the electric pulsed discharge could reach 60%, nevertheless Cs detected in the reclaimed aggregate was only approximately 3% of quantity included in the concrete specimen. Thus most of the Cs was dissolved in water during the discharge process. It is expected that the decontamination method by the pulsed power could reduce the contaminated concrete waste by reusing aggregate. Further, investigations were conducted to test the applicability under the realistic conditions by using the actual radioactive concrete. As a result, no Cs was detected in the reclaimed aggregate from radioactive contaminated concrete. Also no Cs was dissolved in processing water.
