Patent Number: 
Section: claims

1. A disposal container of high-level radioactive waste using multiple barriers, comprising:an inner wall, made of carbon steel, for being cylindrical in shape; a middle wall, made of Inconel™, for being cylindrical in shape and bonded to an outer surface of the inner wall; and an outer wall, made of copper, for being bonded to a lateral surface of the middle wall. 2. The disposal container of high-level radioactive waste using multiple barriers, according to claim 1,wherein the outer wall further installs a heat sink made of aluminum or copper and separated from a lateral surface for releasing heat which is generated inside and transferred to the outer wall, and a radiation fin made of materials same as the heat sink is combined between the heat sink and the outer wall. 3. The disposal container of high-level radioactive waste using multiple barriers, according to claim 2,wherein the radiation fin is combined to the lateral surface of the heat sink. 4. The disposal container of high-level radioactive waste using multiple barriers, according to claim 1,wherein a siphon pipe for storing refrigerants at a certain level is further installed between the heat sink and the outer wall, thereby making the inside in a vacuum state for releasing heat generated from the inside to the outer wall. 5. A barrier system using the disposal container of high-level radioactive waste using multiple barriers in claim 1, comprising:a disposal tunnel which is formed by digging rock formation;a deposition hole which is vertically or horizontally perforated, thereby storing the disposal container;and a buffer which is filled with the deposition hole and the disposal container. 6. The barrier system using the disposal container of high-level radioactive waste using multiple barriers according to claim 5,wherein the buffer is composed of Na-Bentonite.
