摘要： The present disclosure relates to a method of removing a radioactive structure from a nuclear power plant. The method includes flattening at least a portion of an outer surface of a drilling portion of a wall of a nuclear reactor vessel when the portion of the outer surface is uneven, wherein the radioactive structure is buried in the wall and the drilling portion is adjacent to the radioactive structure, installing a drilling device in the flattened drilling portion and performing a drilling operation, extracting the radioactive structure from the wall, and cutting the extracted radioactive structure and storing pieces of the cut radioactive structure in a shielding container.

摘要： A method for decommission of a nuclear power plant includes: a step of removing fuel from a reactor vessel and storing the fuel in a fuel storage pool; a step of carrying the fuel out from the fuel storage pool; a step of, after removing the fuel from the reactor vessel, taking a reactor internal structure inside the reactor vessel out to a work pool storing water and being positioned above the reactor vessel, and decommissioning the reactor internal structure under the water stored in the work pool; a step of carrying the decommissioned reactor internal structure out from the work pool; and a step of, after carrying the reactor internal structure out from the work pool, draining the water from the work pool. The step of taking out and decommissioning the reactor internal structure is started before completion of carrying out of the fuel from the fuel storage pool.

摘要： A method of decommissioning a nuclear reactor including a vessel defining an inner chamber and reactor internal components positioned within the inner chamber includes removing at least some of the internal components and repackaging at least some of the removed internal components in at least one of the first and second predefined sections of the vessel defining a cutting zone between the at least first and second predefined sections. The method further includes disposing the vessel in a container, and encapsulating the internal components in the vessel and encapsulating the vessel in the container to generate a package. A package including components from a decommissioned and dismantled nuclear reactor includes a vessel and a plurality of components encapsulated in the vessel.

摘要： Provided is a remotely operated manipulator which can be applied to a space which is wider on a back side than at an opening part, which has a simple structure, high stiffness, and high reliability. The remotely operated manipulator of the present invention includes: a circular base fixed to a wall surface; a beam which rotates on the circular base; a trolley which moves on the beam; and a mast which is raised and lowered with respect to the trolley and is mounted with a tool unit at a tip. Stiffness is improved by directly fixing the beam to the wall surface by a beam fixing device. Further, a work region is expanded by mounting a bending mast on the tip of the mast.

摘要： Disclosed are examples of methods and systems for cutting up a reinforced concrete mass, in which a drilling tool is provided. In various embodiments, the drilling tool comprises: a drill tube earning a cutter member; a device for causing the drill tube to vibrate, the device comprising a vibration generator for generating longitudinal vibration in the drill tube; a device for injecting a drilling fluid at the distal end of the drill tube; and a device for moving the drill tube along its longitudinal direction. In the disclosed methods and systems, the reinforced concrete mass is cut up by drilling at least one hole with the help of the drill tool by causing the drill tube to vibrate while injecting the drilling fluid into the mass from the distal end of the drill tube.
