Description
Technical field
The invention belongs to nuclear reactor shield design techniques fields, and in particular to a kind of bundled tube shielding construction.
Background technique
Reactor can be released in a large amount of during normal operation due to fission reaction and the activation of part-structure material
Son and gamma-rays, excessive neutron and gamma-rays can generate harm to human body, need effectively to be shielded.Boron carbide, gathers lead
The shielding materials such as ethylene have good shield effectiveness to neutron or gamma-rays, but the physical property of itself seriously constrains these screens
Cover being widely used for material.
Above-mentioned shielding material is packaged for this purpose, needing to study a kind of shielding construction, so that it is had good structure special
Property while be suitable for construction site Fast Installation.
Summary of the invention
The technical problem to be solved in the invention are as follows: propose that a kind of bundled tube shielding construction is packaged shielding material,
It is suitable for construction site Fast Installation while so that it is had good architectural characteristic.
It is described that technical scheme is as follows:
A kind of bundled tube shielding construction, including shielded-plate tube and shielded-plate tube shaping device, shielded-plate tube enclosed inside shielding material,
Shielded-plate tube shaping device shapes to several shielded-plate tubes.
As a preferred solution: shielded-plate tube is in closed hollow containment structure.
As a preferred solution: the shielding material of single kind is encapsulated in each shielded-plate tube, the screen encapsulated in different shielded-plate tubes
It is identical or different to cover material category.
As a preferred solution: the shielding material form is powdered or pellet shape.
As a preferred solution: shielded-plate tube shaping device is banded structure or hollow shell structure, several shielded-plate tubes are formed
Shielding tube bank shape.
As a preferred solution: shielded-plate tube shaping device is tower structure.
As a preferred solution: several shielded-plate tubes according to the difference of the shielding material type of enclosed inside and layered arrangement with
Inside tower structure shielded-plate tube shaping device.
The invention has the benefit that
Different types of shielding material is encapsulated into shielding tube bank by the present invention in advance by prefabricated method, by shielding
Tube bank promotes the mechanical property of shielding material, while being packaged to it.Ensure that the shielding materials such as boron carbide powder can be normal
It uses, the shielding materials such as polyethylene, lead will not reveal the integrality for ensuring shielding construction fusing.Due to shielding material at
Bundle-shaped can be easily loaded into shielding construction at the construction field (site), or the structure shielded as needed is direct
Sizing, provides advantage for the Fast Installation of shielding construction at the scene.The shielding material of bundle-shaped is capable of Fast Installation
Characteristic is also beneficial to be replaced at any time according to the demand of shielding design, or is layered according to the characteristic of required shielding particle
Arrangement, it is ensured that there is optimal shield effectiveness, there is potential economic value.
