Embodiment 1

[0022] figure 1 It is a perspective view of a movable shielding body according to an embodiment of the present invention, showing a state in which the movable shielding structure is pushed out from the fixed shielding structure. figure 2 is a perspective view of a fixed shielding structure of a mobile shielding body according to an embodiment of the present invention. image 3 It is a perspective view of a movable shielding structure of a movable shielding body according to an embodiment of the present invention, showing a state in which the movable shielding structure is in an initial position.

[0023] Such as figure 1 As shown, the movable shielding body in this embodiment includes a fixed shielding structure 1 , a movable shielding structure 2 and a driving mechanism 8 . The movable shielding structure 2 can move in one direction (hereinafter referred to as the axial direction, ie the X direction in the figure) relative to the fixed shielding structure 1 . Combine belo...

Embodiment 2

[0037] This embodiment also discloses a glove box, which includes a box body and the above-mentioned movable shielding body. The mobile shielding body is arranged in the box body and is in the active area of ​​the material, and is used to push fuel rods out of the glove box. , and at the same time dynamically shield the material.

[0038] According to the present invention, the movable shielding body can move along with the materials to be shielded, so as to realize dynamic shielding in as wide a range as possible, and at the same time effectively save materials for manufacturing shielding shells. The stepped channel formed by the fixed shielding structure can effectively reduce the radiation level of the active area of ​​the MOX fuel rod while ensuring the ingress and egress of materials. By setting up a movable shield, the follow-up protection of the active area of ​​the operated MOX fuel bundle can be realized, ensuring the protection safety of the fuel bundle when it is ou...

Abstract

The invention discloses a movable shielding body which comprises a fixed shielding structure which comprises a shielding shell and a stainless steel frame, and the shielding shell and the stainless steel frame are connected through screws to form a stepped feeding channel and an inner cavity; the movable shielding structure is combined with the fixed shielding structure, and the movable shielding structure can move in the axial direction relative to the fixed shielding structure; and the driving mechanism is used for providing driving force to drive the movable shielding structure to move. The invention further discloses a glove box.

Description

technical field [0001] The invention belongs to the field of radioactive nuclear fuel manufacturing, and in particular relates to a mobile shielding body structure, which is used for shielding protection in the processes of feeding MOX (mixed oxide) fuel rods, manual cluster assembly and fuel rod bundle out of the box, etc., to realize For the dynamic shielding of radioactive materials, the present invention also relates to a glove box comprising the movable shielding structure. Background technique [0002] In the field of nuclear fuel manufacturing, for the occasions where radioactive materials need to be manually handled inside the glove box, the shield and the glove box are usually integrated for overall protection. Adding the thickness of the shielding shell will easily lead to an increase in the thickness of the glove box, and the production cost is high. At the same time, because the operator needs to wear lead-containing gloves (or tungsten-containing gloves, etc.) t...
