## Abstract

The present invention relates to a disposal container and a storage system for high-level radioactive waste and, more specifically, to a disposal container for high-level radioactive waste using multiple barriers and a barrier system using thereof, the disposal container having the multiple barriers consisting of an inner wall made of carbon steel for excellent corrosion resistance and ease of manufacture, a middle wall made of Inconel, which is bonded to a lateral surface of the inner wall, and an outer wall made of copper, which is bonded to a lateral surface of the middle wall.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 2)

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.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 5)

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.
