Description

Blasting is considered to be one of methods for dismantling of power reactor facilities made of firm structure. An automatic control of blasting with high energy is necessary for practical use in order to suppress the exposure time to human being. In this study, technology for dismantling activated concrete structures for shielding organism into blocks and collecting them were developed. The classifying technology was also examined. The cutting efficiency of the liner using the plastic explosive was investigated. In addition, a numerical simulation method for finding out dynamic fracture mechanism of concrete was studied. (A.
