Definitions

the invention relates to a cylindrical container made of a reinforced concrete wall, suitable for the transport and storage of radioactive materials, with an opening on the front side which can be closed by a reinforced concrete cover.
the reinforced concrete wall and the reinforced concrete cover of the container are clad on the inside and outside with steel sheets.
Such a container is known from DE-OS 33 31 892 and has the advantages that the required shielding of the radiation is guaranteed by the reinforced concrete, which emanates from radioactive material, and that the steel sheet covering the concrete increases the impact resistance of the container . Furthermore, due to its relatively low manufacturing costs, the known container is also economically suitable to be used as a storage container for intermediate or final storage of the radioactive material introduced into the container.
the invention has for its object to improve the known container and to achieve one that is characterized by smaller dimensions and a lower weight compared to the known container with the same capacity and in particular the handling of the lid is simplified.
the inner lining of the reinforced concrete wall according to the invention consists of a steel sheet that has a greater wall thickness than the steel sheet forming the outer lining of the reinforced concrete wall
the outer lining of the reinforced concrete wall consists of a steel sheet which has a greater wall thickness than the steel sheet of the reinforced concrete wall forming the inside cladding. Due to the relatively thick reinforced concrete wall, the area of the outside cladding is considerably larger than that of the inside cladding, which explains the considerable weight reduction in the arrangement according to the invention in a simple manner.
the wall sheet steel cladding which is larger than the steel sheet cladding on the outside, creates the prerequisite for attaching threaded anchors to the steel sheet forming the inside cladding, which according to the invention are arranged on the side of the cladding facing the reinforced concrete in a uniform distribution over the circumference of the opening.
the screw bolts which can be screwed into the threaded anchors and inserted through holes in a cover facilitate the handling of the reinforced concrete cover, in particular in that the cover forms the outside cladding of the reinforced concrete cover and protrudes radially outwards about it, so that the concrete core of the reinforced concrete cover can be kept much smaller in diameter than its cover forming the outside cladding. This also results in a weight saving, which affects both the easier handling of the lid and that of the container as a whole.
the outer diameter of a lost formwork surrounding the concrete core of the reinforced concrete cover is at least smaller than the outer diameter of a sleeve, which is used to guide the screw bolts and is arranged coaxially to the threaded anchors between the inner lining and the outer cover of the cover the pitch circle on which the bolts passed through the sleeves are arranged.
the sleeves used to guide the screw bolts can be placed unhindered by the reinforced concrete cover around the outer circumference of the concrete core coaxially with the bores in the threaded anchors, so that the screw bolts can be properly screwed in via the bores of the correspondingly angularly oriented cover of the reinforced concrete cover, without requiring a special alignment of the reinforced concrete cover.
a base plate of the reinforced concrete cover forming the inside lining of the cover has a stepped edge, which has an edge surface on an end face of the lining of the steel sheet forming the wall rests.
the reinforced concrete cover lies in the manner described above on the end face of the steel sheet forming the inside cladding of the wall, further adjustment of the reinforced concrete cover is unnecessary, in particular also twisting in relation to the container, if, according to a further embodiment of the invention, the outside cover of the cover is through the screw bolt which can be screwed into the threaded anchor is detachably connected to the reinforced concrete cover.
This configuration according to the invention does not require an angular adjustment of the cover as a whole for the proper connection of the reinforced concrete cover to the reinforced concrete container, but only such an adjustment with regard to the outer cover of the reinforced concrete cover, which is much easier to handle.
an embodiment of the invention provides that the wall thickness of the steel sheet forming the outer cladding of the wall to the wall thickness of the steel sheet forming the inner cladding of the wall is in a ratio of 1: 3 to 1: 5 and preferably in a ratio of 1: 4.
the total weight of the container can be optimized in relation to its capacity, while complying with all safety requirements, in particular also with regard to possible shock loads during transport.
the cylindrical container suitable for the transport and storage of radioactive materials consists of a reinforced concrete wall 1, for the production of which concrete, for example, grade B 25 K3 with a density of 2.5 g / cm3 according to DIN 1045 is used.
the reinforced concrete wall 1 is reinforced in a manner known per se with a steel reinforcement (not shown) and clad on the outside with a steel sheet 2 and on the inside with a steel sheet 3.
the steel sheet 2 forming the outer lining has a wall thickness of preferably 15 mm, whereas the wall thickness of the steel sheet forming the inner lining is preferably 60 mm.
eight threaded anchors 5 are welded to the steel sheet 3 forming the inside cladding of the reinforced concrete wall 1 in a uniform distribution over the circumference of an end-side container opening 4, which are arranged so that their threaded holes 6 lie on a common pitch circle and parallel are aligned with the container axis.
the container opening 4 can be closed by a reinforced concrete cover 7, which consists of a concrete core 8, which is enclosed by an inside cladding 9 and an outside cover 10 made of sheet steel disks and by a lost formwork 11 made of a sheet steel cylinder.
the inside cladding 9 of the concrete core 8 consists of a steel sheet disc, the outer diameter of which is larger than the inside diameter of the container, the steel sheet disc having a stepped edge such that it rests only with an edge surface 12 on the end face of the steel sheet 2 forming the inside cladding and otherwise penetrates into the container opening 4 with a cylindrical part in the manner of a stopper.
the cover 10 of the concrete core 8 consists of a sheet steel plate, the outside diameter of which is greater than the outside diameter of the sheet steel cylinder forming the lost formwork 11.
eight holes 13 are provided on a pitch circle, which corresponds to that of the threaded holes 5, in a uniform distribution over the circumference of the cover 10, through which bolts 14 can be inserted, which are guided in sleeves 15 , can be screwed into the threaded holes 6 of the threaded anchor 5.
