Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Such as Figure 1-3 Shown is the shock absorber for the nuclear fuel transport container provided by the present invention. The shock absorber is used in conjunction with the transport container and is installed on both ends of the transport container through bolts to absorb the impact energy under normal transport and accident drop conditions. , to ensure the safety of nuclear fuel transportation.

[0025] The shock absorber includes a stainless steel cavity made of an outer end frame 1 , an outer ring plate 4 and an inner end frame 5 . The inside of the cavity is filled with buffer material 2 to improve the impact resistance of the nuclear fuel. The buffer material 2 is composed of wood with different densities and staggered grain directions. The buffer material 2 is arranged in partitions, wherein the top of ...

Abstract

The invention relates to a damper for a nuclear fuel transport container. The damper is arranged at both ends of the transport container and comprises a cavity enclosed by an outer end frame (1), an inner end frame (5) and an outer ring plate (4), and the cavity is filled with a buffering material (2); the outer end frame (1) is formed by connecting an outer bottom plate (11) with an inner bottom plate (15); and the inner end frame (5) is formed by connecting an inner side plate surface (51) with an inner ring plate (52). By adoption of the damper provided by the invention, in a nuclear fuel transport process or an accident working condition, the impact resistance of nuclear fuels can be improved, the influence to the nuclear fuels is relieved, and the transport safety of the nuclear fuels is guaranteed; and the damper is simple in structure and is easy to operate.

Description

technical field [0001] The invention belongs to the field of dangerous goods transportation, and in particular relates to a shock absorber for a nuclear fuel transportation container. Background technique [0002] Nuclear fuel and other radioactive substances need to be transported safely during transportation, that is, the transportation container should meet the requirements for containment, shielding, and criticality of radioactive substances under the relevant conditions required by regulations and standards. Therefore, in the design of the transport container, it is necessary to consider the selection of a suitable shock-absorbing buffer structure to ensure the safety of the nuclear fuel inside the container. [0003] In the process of realizing the above-mentioned safe transportation of nuclear fuel, the inventors have found that at least the following problems exist in the prior art: [0004] There is a lack of a shock-absorbing buffer structure that is specially sui...
