Structural cutting device of nuclear power plant using dry method and adjustable cooling fluid supply

摘要

The present invention provides a structure cutting device for a nuclear facility capable of adjusting a cooling fluid supply amount which improves durability. The structure cutting device for a nuclear facility capable of adjusting a cooling fluid supply amount comprises: a wire enclosing a surface of a structure; a plurality of pulleys arranged on corners of the structure to guide the wire; a drive motor arranged at the center of the plurality of pulleys to give power to the wire; a drilling unit to create holes communicating in the thickness direction of the structure; and a sealing cover formed on the outside of the multiple components to prevent dust created in the structure when cutting from being discharged. The pulleys include: a plurality of first pulleys penetrating the structure through the holes communicating in the thickness direction of the structure to be arranged; and a plurality of second pulleys facing the first pulleys with respect to the structure to be arranged. The wire penetrates the structure along the inner surfaces of the holes from the first pulleys to be arranged to cut the structure depending on an operation of the drive motor. A cooling fluid supply device to supply water to the wire is included in the sealing cover to allow a user to adjust a supply amount of a fluid cooling the wire.
