Problems solved by technology

For example, the "medium and low-level radioactive nuclear waste storage and transportation container" disclosed in the Chinese utility model patent No. 200920039600.3 uses a single-layer reinforced concrete material as the shielding layer. The shielding structure of this storage and transportation container is not very reasonable, and the shielding effect not ideal
In addition, shielding is usually achieved by increasing the thickness of the shielding material. The container is bulky, heavy and inconvenient to operate.

Embodiment Construction

[0020] Such as figure 1 and figure 2 As shown, a cylinder of a radioactive substance container is composed of an inner cylinder 8 and an outer cylinder 5, and two shielding layers, a depleted uranium layer and a lead shielding layer 2, are arranged between the inner cylinder 8 and the outer cylinder 5 from inside to outside. Both the inner cylinder 8 and the outer cylinder 5 are hollow cylinders, and the upper and lower ends of the inner cylinder 8 are fixedly connected to the upper and lower ends of the outer cylinder 5 through the upper end 1 and the lower end 7 fixed thereon respectively. The lead shielding layer 2 is filled in the cavity formed by the depleted uranium layer, the inner cylinder 8 , the outer cylinder 5 , the upper end 1 and the lower end 7 . The depleted uranium layer is a multi-section sleeve structure, which is composed of top depleted uranium sleeve 3, more than one middle depleted uranium sleeve 4 and bottom depleted uranium sleeve 6. The adjacent two...

Abstract

The invention relates to a barrel for a radioactive substance container. The barrel consists of an inner barrel and an outer barrel fixedly connected together, wherein two shielding layers, namely a depleted uranium layer and a lead shielding layer, are respectively arranged between the inner barrel and the outer barrel from the interior to the exterior. The barrel is simple in structure, convenient to machine, good in shielding effect, small in volume, convenient to operate, high in social and economic values and suitable for popularization and application, and can effectively shield rays.

Description

technical field [0001] The invention relates to a cylinder body of a radioactive substance container, in particular to a cylinder body with a double-layer shielding structure for a radioactive substance container, belonging to the technical field of the nuclear industry. Background technique [0002] Because radioactive substances have certain damage to the environment and the human body, when transporting or storing radioactive substances, it is necessary to use a container with a shielding structure to shield the radioactivity to prevent harm to the human body and the environment. Under the same other conditions, the farther away from the radiation source, the lower the dose rate of radioactive substances; if the same shielding material and structure are used, the greater the thickness of the shielding layer, the better the shielding performance; and under the same shielding thickness , the greater the density of the shielding material, the better the shielding performance...
