Abstract: The present disclosure relates to a method of removing a nuclear power plant activation structure. Specifically, an embodiment of the present disclosure may provide a method of removing a nuclear power plant activation structure including flattening at least a portion of a wall surface of a peripheral portion of a wall of a nuclear reactor, the wall including a buried portion in which a nuclear power plant activation structure is buried and the peripheral portion circumferentially surrounding the buried portion; installing a drilling device in the flattened peripheral portion and performing a drilling operation; removing the nuclear power plant activation structure from the buried portion; and cutting the removed nuclear power plant activation structure and storing pieces of the cut nuclear power plant activation structure in a shielding container.
