DEVICE AND METHOD FOR REMOVING AND CUTTING METAL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To remove and cut a metal structure having radioactivity at high processing speed. SOLUTION: The removing/cutting device of the metal structure comprises a pool 40 for processing reserving electrolytic solution 2; a gripping mechanism 9 that is disposed in the pool 40 for processing and supports the metal structure 8 having radioactivity; a device body 1 to be installed on the supported metal structure 8; a processing electrode 3 arranged on a processing face of the metal structure 8; an electrolytic solution nozzle 21 that is disposed near this processing electrode 3 and applies the electrolytic solution 2; a power supply 4 for supplying current for making the metal structure 8 as the positive electrode and the processing electrode 3 as the negative electrode electrochemically react with each other in the electrolytic solution 2; and a driving mechanism (for example, feeding mechanism 10a) that is disposed between the device body 1 and the processing electrode 3 and drives the processing electrode 3 according to the progress of the electrochemical reaction.
