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
The present invention relates to a kind of bomb cylindrical shell,, specifically relate to a kind of bomb double-layer shielding structure cylindrical shell, belong to the nuclear industry technical field.
Background technology
Because radioactive material confrontation environment and human body all have certain infringement, therefore, when transportation or storage of radioactive material, the container that just needs employing to have shielding construction is shielded its radioactivity, to prevent the injury to human body and environment.In the situation that all the other conditions are identical, far away apart from radioactive source, the dose rate of radiomaterial is lower; If adopt identical shielding material and structure, shielding thickness is larger, and shielding properties is better; And, under identical shielding thickness, the density of shielding material is larger, shielding properties is better.At present the most frequently used radiomaterial storage, be mostly drum-shaped, employing be that reinforced concrete or the lead of individual layer is made.As disclosed as No. 200920039600.3 patents of Chinese utility model patent " in, low-level level radioactive nuclear waste storage fortune container ", what adopt is exactly that the Reinforced Concrete Materials of individual layer is as screen layer, this storage shielding construction is not quite reasonable, and shield effectiveness is also not ideal.And usually adopt the mode that increases shielding material thickness to realize shielding, container volume is larger, heavier, inconvenient operation.
Summary of the invention
For the defect of prior art, the purpose of this invention is to provide a kind of simple in structure, shielding good, the barrel for radioactive substance container of easy to process, economical and practical double-layer shielding structure.
For reaching above-mentioned purpose, the present invention has adopted following technical scheme:
A kind of radiomaterial cylindrical shell, cylindrical shell is comprised of the inner core be fixed together and urceolus, and depleted uranium layer and the two-layer screen layer of lead shield layer are set respectively between inner core and urceolus from inside to outside.
The present invention also can further realize by following scheme:
Described barrel for radioactive substance container, wherein, described inner core and urceolus are a hollow cylinder, and the upper/lower terminal of inner core is fixedly connected with the upper/lower terminal of urceolus by the upper and lower termination be fixed thereon respectively.
Described barrel for radioactive substance container, wherein, described depleted uranium layer adopts the multi-section sleeve structure, the depleted uranium cover be movably connected more than 3 joints, consists of, and the depleted uranium cover is sheathed on the outside of inner core, with inner tank theca, is flexibly connected.
Described barrel for radioactive substance container, wherein, form a cavity between described inner core, urceolus, depleted uranium layer and upper and lower termination, the lead shield layer is filled in cavity.
Described barrel for radioactive substance container, wherein, described depleted uranium cover is comprised of top depleted uranium cover, middle part depleted uranium cover and bottom depleted uranium cover more than 1, and two adjacent joint depleted uranium inner rooms are threaded connection, and in its assembling gap, are provided with the lead foil pad; Bottom depleted uranium cover is flexibly connected with inner tank theca.
Described bomb cylindrical shell, wherein, described inner core lower end is fixedly connected with one and is provided with externally threaded hollow inner cylinder base, and the lower end of inner core base is fixedly connected with the urceolus lower end by lower end; Described bottom depleted uranium cover is connected with the inner core whorl of base.
Owing to having adopted above technical scheme, the present invention possesses following technique effect:
1, bomb cylindrical shell of the present invention, adopt depleted uranium-plumbous double-layer shielding structure, and depleted uranium has the physical characteristicss such as high density, high rigidity, high tenacity, and its density is 19.3g/cm3, can be equal to tungsten, is almost plumbous 2 times, and shielding properties is good; And outer field lead is the material of the safeguard of the manufacture radioactive radiation commonly used, X ray, itself and depleted uranium form the shielding properties that double-layer shielding structure has been strengthened storage, can effectively shield ray, and shield effectiveness is good;
2, bomb cylindrical shell of the present invention, adopt that depleted uranium is this extracts secondary product that the nuclear material uranium 235 obtains later as shielding material from metallic uranium, improved the utilization factor of nuke rubbish, reduced the expense of nuclear waste management;
3, bomb cylindrical shell of the present invention, adopt lead-depleted uranium double-layer shielding structure in the zone of radiomaterial, all the other positions adopt lead shield structures, have reduced container dimensional, for container manufacture and operation provide convenience;
4, bomb cylindrical shell of the present invention, inner core is by being fixedly connected with urceolus, and the mode be threaded connection connects the depleted uranium cover, in the cavity that inner core and urceolus form, fill with plumbous, simple in structure, easy to process, economical and practical, there is preferably social economic value, suitable applying.
