[0002] Nuclear waste generally refers to the radioactive waste that is no longer needed after nuclear fuel production, processing and nuclear reactor use. It also specifically refers to the spent fuel of nuclear reactors, which is no longer needed and radioactive waste such as uranium left after reprocessing to recover usable nuclear materials such as plutonium.

[0003] Many traditional waste collection containers are single-layer tank structures, which not only have low sealing tolerance, but also may collide during transportation or cause the waste core in the tank to shake, causing the tank to be damaged or overturned, resulting in nuclear waste leakage.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0007] The buffer mechanism includes a plurality of elastic components, which are evenly distributed in a circular array at the top and bottom positions between the circumferential outer wall of the inner tank body and the circumferential inner wall of the outer tank body, and both the outer tank body and the inner tank body are provided with a reinforcing structure for improving the strength of the tank body.

[0009] As a preferred embodiment of the utility model, a slide groove is provided at the center position of the end of the connecting rod 1 away from the outer wall of the outer tank body, and the end of the connecting rod 2 away from the inner tank body wall is inserted into the slide groove to be connected in a sliding fit, and a spring is installed on the outer side of the circumference of the connecting rod 2, between the end of the connecting rod 1 close to the connecting rod 2 and the end of the connecting rod 2 away from the connecting rod 1.

[0010] As a preferred embodiment of the present utility model, there is a gap between the inner wall of the outer tank body and the outer wall of the inner tank body, and the cross section of the outer tank body is in an arc shape convex outward.

[0011] As a preferred embodiment of the present utility model, the reinforcement structure includes protective rings, which are evenly spaced and fixedly connected to the outer side of the circumference of the outer tank body.

[0012] As a preferred embodiment of the present utility model, the cross-section of the protective ring is a semicircular shape convex outward, and the protective ring is made of silicone material.

[0013] As a preferred embodiment of the utility model, the reinforcement structure further comprises a reinforcement section, which is arranged in the middle section of the circumferential side wall of the inner tank body, and the reinforcement section is in the shape of a corrugated tube with a serpentine cross-section.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The double-layer tank body of the outer tank body and the inner tank body improves the sealing storage effect of the container device for nuclear waste and greatly improves the fault tolerance of nuclear waste leakage caused by tank rupture.

[0016] 2. The elastic component arranged between the double-layer tank body can play a buffering role through the elastic effect of the spring when the tank body is hit during transportation, thereby reducing the impact on the inner tank body and improving the protection of the container.

[0017] 3. Through the setting of the reinforcement structure, the setting of the protective ring not only strengthens the strength of the outer tank body, but also further improves the overall protection effect of the container; the setting of the reinforcement section improves the overall strength and tensile resistance of the inner tank body, and the bending shape of the bellows makes it have better pressure-bearing effect and certain wave-blocking effect, which is conducive to improving the transportation stability and avoiding the shaking of the waste core in the inner tank body causing the container to overturn.
