Definitions

the invention relates to a transport and storage device for radioactive materials consisting of a cylindrical container.
the container is made with a closed casing made of steel, concrete or cast iron and has an opening at the front that can be closed by a lid.
An end face of the cover can be pressed against an end face of the casing.
An edge surface of the cover is covered by a collar formed from the casing. Radial openings are provided in a uniform distribution over the circumference of the collar. These are opposite recesses arranged in the lid.
Such a transport and storage device is known from DE-OS 33 31 892 and, despite the relatively inexpensive construction, nevertheless meets the high requirements to be placed on the safety of transport and storage devices for radioactive material.
the invention has for its object to simplify a device of the type described in terms of its manufacture and handling, without thereby affecting its high level of functional reliability.
the recesses which are conically narrowed towards the center of the cover and the pressable therein, which are guided in the openings of the collar, fulfill both the function of the screws and the cylindrical bolts of the known device, so that only one is required instead of two differently designed groups of connecting and fastening means is. Due to the conicity of the pins and the recesses according to the invention, the end face of the cover can be pressed axially firmly against an end face of the casing and at the same time also radially aligned and fixed.
each pin has a continuous concentric bore for a threaded pin, which can be screwed into a threaded hole in the bottom of the recess.
This configuration ensures permanent cover locking even when the pins should tend to move radially outwards out of the recesses due to their relatively strong conicity.
each threaded bolt consists of an Allen screw which can be countersunk in the pin with its head.
Each Allen screw can be fixed against unintentional loosening according to a further embodiment of the invention by means of a circlip that can be inserted in the bore of the pin.
the pins can also be welded to the collar of the wall to secure the lid closure, which is particularly recommended if the container loaded with radioactive material is to serve as an intermediate or final storage device.
the low manufacturing costs of the device according to the invention are particularly important.
the device consists of a cylindrical container, the closed casing 1 of which is made of steel and concrete 4 clad with steel sheets 2 and 3 on the inside and outside.
a cover washer 5 is welded to the steel sheets 2 and 3, which serve as lost formwork for the steel-concrete 4, which is flush with the upper end face of the steel sheet 2 forming the inside cladding and is thus towered over by the steel sheet 3 forming the outside cladding that the protruding part of the steel sheet 3 forms a collar 6.
An end opening of the container can be closed by a lid 7, which is also made of steel-concrete 8 and is clad on both end faces with sheet steel disks 9 and 10 and on its edge face with a sheet steel cylinder 11.
the cover 7 lies with an edge surface 12 of the sheet steel disc 9 facing the interior of the container on the cover ring disc 5, while the steel sheet cylinder 11 of the cover 7 is laterally covered over its full height by the collar 6 formed from the steel sheet 3.
a base plate 13 is welded to the underside of the steel sheet disc 9, which has a diameter that is slightly larger than the inside diameter of the container and extends into a recess 14 in the edge region of the steel sheet 2.
a cover plate 15 is welded onto the upper side of the sheet steel plate 10 and has a diameter which is slightly larger than the inside diameter of the collar 6 and can be welded to the end face thereof.
openings 16 are provided in the sheet steel cylinder.
a radially aligned insert 17 is welded to the sheet steel cylinder 11, which is additionally welded to the sheet steel disk 9 via a radial web 18 and is cast in the steel concrete 8 of the cover 7.
Each insert 17 has a recess 19 which is conically narrowed towards the center of the cover 7, the cone angle of which in the exemplary embodiment is approximately 11 °, 25 '.
a threaded bore 21 is provided in the bottom 20 of the insert 17 coaxially with the recess 19.
openings 22 in the collar 6 which are aligned with the openings 16 in the sheet steel cylinder 11 are provided.
a conical pin 23 the cone angle of which coincides with that of the recesses 19, can be driven in, a corresponding wall thickness of the collar 6 ensuring that the pin 23 receives a reliable guidance through the reveal of the openings 22.
each pin 23 is provided with a continuous coaxial bore 24, in which a threaded bolt 25 in the form of an Allen screw can be inserted and screwed into the threaded bore 21 in the base 20 of the insert 17.
a threaded bolt 25 in the form of an Allen screw can be inserted and screwed into the threaded bore 21 in the base 20 of the insert 17.
a circlip can finally be inserted into the enlarged part of the bore 24 or the head 26 can be welded to the collar 6.
the same effect can be achieved with a plate that completely or partially covers the opening of the bore 24 and is also welded to the collar 6 if the head 26 in the end position of the pin 23 is flush with the outside of the collar 6.
