Section: claims

1. A method of cutting and removing a nuclear reactor, comprising the steps of: pressure-feeding a grouting material into a pressure vessel and to peripheral members outside said pressure vessel for integration thereof, and cutting said pressure vessel, with said pressure-fed grouting material therein, starting with the outer periphery of said pressure vessel, wherein said step of cutting includes the step of cutting with the use of a wire saw having diamond grains on the surface thereof.  packing a cement grouting material or a synthetic resin material into said reactor;  covering the outer periphery of said reactor with a concrete;  cutting said reactor, with said material packed therein, into blocks starting with outer periphery thereof with a wire saw using diamond beads; and  carrying out said blocks.  packing a cement grouting material or a synthetic resin material into said reactor;  plasma-cutting the outer part of said reactor, with said material packed therein;  cutting the inside of said reactor, with said material packed therein, with a wire saw using diamond beads into blocks; and  carrying out said blocks. 2. A method of cutting and removing a nuclear reactor according to claim 1, wherein double cutting is carried out by the use of a preceding cutting edge and a cutting groove width adjustment cutting edge. 3. A method of cutting and removing a nuclear reactor, comprising the steps of: 4. A method of cutting and removing a nuclear reactor, comprising the steps of: 5. A method of cutting and removing a nuclear reactor according to claim 1, wherein said step of pressure-feeding said grouting material includes the step of pressure-feeding said grouting material through at least one of an opening in an upper portion of said pressure vessel and an opening in a jaw portion of said pressure vessel. 6. A method of cutting and removing a nuclear reactor according to claim 1, wherein said grouting material is a non-shrinkable type material.
