The Fukushima Dai-ichi Nuclear Plant accident has resulted in a large amount of radioactively contaminated concrete. The possible application of the pulsed power discharge to reduce the amount of contaminated concrete debris as radioactive waste was investigated. This method could decontaminate and reduce the contaminated concrete wastes by separating contaminated matrix from uncontaminated coarse aggregate under pulsed power discharge process.
