Definitions

  • the invention relates to storage containers for radioactive waste, more particularly suitable for the storage of weakly and moderately radioactive solidified waste from nuclear sites.
  • the containers concerned are concrete containers such as that described in the British patent application GB-A-21 32 814 and the waste is in particular constituted by so-called process waste such as filters, evaporator concentrates and resins used ion exchangers. Concrete containers are essential for the transport and storage of such radioactive waste as soon as the radioactivity measured exceeds 200 mrem / h.
  • Liquid waste is poured into containers and then conditioned for solidification
  • Storage containers should be designed to provide optimal usable volume while ensuring biological protection over time.
  • the known containers consist of a container closed by a stopper.
  • the container comprises a concrete shell or envelope and an inner metal tank, the wall of which comprises, if necessary, a layer of lead constituting a shield.
  • the plug is a plug, most often made of concrete, poured on site. Concrete plugs poured in situ sometimes show some cracking due to the dimensional variations of the concrete over time and they are of variable quality and difficult to control.
  • Other known plugs consist of lead beads embedded in a mixture of pitch and epoxy resin. This solution offers better protection against radiation, but it is difficult and expensive to achieve.
  • the object of the invention is to obviate these drawbacks by proposing a container allowing faster and safer closure with the aid of a stopper, the quality of which can be checked beforehand.
  • the subject of the invention is a container for storing radioactive waste as characterized in claim 1.
  • the use of the invention allows, in addition, a lower requirement in qualification of operating personnel, which is of interest, particularly in exported installations (South Africa, South Korea, People's China, ).
  • FIGS 1 and 2 show a first embodiment of the invention.
  • the container 1 consists of a container 2 hermetically closed using a prefabricated concrete plug 3.
  • the container has an outer casing 4 of concrete and a composite inner wall 5 forming a tank.
  • the internal wall is of cylindrical shape and composed of different elements arranged in the following order, seen from the inside to the outside of FIG. 1: first a first steel element 6 forming the internal face of the container, followed by an element made of heavy material such as lead 7 forming a shield against radiation. This shielding is covered by a second steel element 8 followed by a flexible element 9.
  • the flexible element 9 has the function of absorbing the dimensional variations over time of the envelope 2, which is essential to avoid cracks in the concrete caused by tensions in the latter during its removal.
  • the flexible element 9 must also serve as thermal insulation when filling the container 2, since the waste can be poured into the container in the state hot and undergo a temperature rise during solidification, which causes thermal stresses in the concrete. It is therefore desirable to mitigate these stresses by having a heat-insulating element between the tank and the concrete envelope.
  • the flexible element 9 is preferably made of expanded polystyrene.
  • the element must be protected against the humidity contained in the concrete and this protection can be ensured by a layer 10 of an appropriate material, for example polyane, applied to the external face of the flexible element 9 in order to prevent that it is in direct contact with the concrete casing 4.
  • a layer 10 of an appropriate material for example polyane
  • An agitator 13 can be used for packaging the waste for solidification and it then remains with the waste in the container.
  • a shoe 11 forming a support for the axis 12 of the agitator 13 with blades 14 is fixed to the center of the bottom of the tank 5.
  • the container 2 is provided with an annular element 15 integral with the open end of the tank 5 and intended to form a seat for the plug 3.
  • the annular element 15 comprises a radial core 16, a skirt 17 directed upwards and an axial re-entrant collar 18 which forms an anti-overflow member during the agitation of the waste with a view to its conditioning and which delimits the useful volume of the container.
  • the container 2 is, over its entire periphery, provided with a groove 19 intended to receive a belt for handling the empty container or the filled and closed container.
  • the concrete plug 3 is provided with a metal coating 20 whose face facing the tank 5 defines therewith the interior volume of the container.
  • the metal coating 20 is in the form of a bowl.
  • the side wall 21 of the bowl 20 cooperates, when the cap 3 is in place on the container 2, with the skirt 17 of the annular element 15 of the container 2 so that their respective edges form means of connection of the cap with the container.
  • the edges are juxtaposed and assembled over their entire length by a continuous weld bead 22.
  • the weld bead is advantageously applied using a welding robot, which makes it possible to automate the entire sealing process. This assembly process also has the advantage of ensuring an absolutely tight seal between the elements.
  • the side wall 21 of the bowl 20 and the skirt 17 of the annular element 15 preferably have a flared shape.
  • the flared shape ensures the centering of the plug 3 when it is placed on the container 2.
  • the skirt 17 of flared shape forms a bearing surface against which the side wall 21 of the covering 20 also flared rests, this which also contributes to sealing between the plug 3 and the container 2.
  • the side wall 21 of the bowl 20 and the skirt 17 of the annular element 15 can also be of cylindrical shape, which then requires a certain play between these elements to facilitate the fitting of the plug.
  • the outer concrete casing 4 projects in height above the skirt 17 of the annular element.
  • the open face of the plug 3 preferably flush or slightly exceeds the upper end face of the casing 4, when the plug is placed on its seat, in order to present a surface as homogeneous as possible to facilitate the stacking of the containers during storage.
  • the envelope 4 of the container 2 is, at the end of its internal wall which faces the plug 3, provided with a continuous recess 23a.
  • the plug is provided with a corresponding recess 23b extending over the entire periphery of its upper face.
  • the recesses 23a, 23b form, when the cap is placed on the container, a groove 23 into which the edges of the bowl 20 and of the skirt 17 open.
  • the groove 23 is filled with a mortar 24 to protect the weld bead 22.
  • the groove 23 communicates with the external lateral wall of the casing 4 by radial grooves 26 forming weirs regularly disposed at the open end of the latter.
  • the container is preferably provided with a ring 25 of heavy material of the same kind as the shield 7 forming a shield compensating for the reduction in thickness of the wall of the container and of the plug due to the presence of said groove 23.
  • L 'ring 25 is disposed inside the container 2 and connected to the annular element 15 thereof.
  • the ring 25 can be an insert as shown in FIG. 1 or be part of the shield 7 of the internal wall 5.
  • the plug 3 is provided with two threaded sockets 27 arranged in opposite recesses 28 on its upper face.
  • the sockets are intended to cooperate with screws 29 integral with lifting rings 30 put in place only during the handling of the plug.
  • FIG. 3 is a partial sectional view of a variant of the first embodiment of the invention.
  • the container 31 consists of a concrete casing 32 and a composite internal wall 33 forming a tank.
  • the internal wall 33 has the same structure as the internal wall already described with reference to FIG. 1.
  • the concrete plug 34 has a metal coating 35 in the form of a plate.
  • the container 31 has a flat annular element 36 which forms a seat for the stopper.
  • the edge of the covering 35 and the outer edge of the annular element 36 protrude towards the external lateral surface of the container.
  • the stopper 34 is provided with a recess 37a extending over its entire periphery and the casing 32 of the container is provided with a corresponding element 37b at the upper end of its external side wall.
  • the recesses 37a, 37b form, when the stopper is placed on the container, a groove 37 into which the edges of the metal coating 35 of the stopper and of the annular element 36 of the container open.
  • Said edges constitute respective connection means of the covering 35 and of the annular element 36. They are connected by a continuous weld bead 38.
  • the plug 34 is provided with at least two channels 39 which connect the groove 37 to the upper face of the plug 34.
  • the channels 39 of which are intended for filling groove 37 by a mortar (not shown) and the evacuation of air therefrom.
  • the groove 37 must be closed using a formwork (not shown) after the application of the weld bead 38, which allows the filling of the throat and the protection of the weld bead.
  • the stopper 34 is preferably provided with a centering rim 40 disposed on its face facing the container 31.
  • the centering rim 40 cooperates with the internal edge of the annular element 36 of the container 31 for the establishment of the stopper 34 on the container.
  • the annular element 36 is, as in the embodiment already described, preferably provided with a re-entrant axial flange 41 delimiting the opening of the container 31 and forming an anti-overflow member cooperating with the centering rim 40.
  • the container 31 comprises a ring 42 of heavy material forming a shield compensating for the reduction in thickness of the wall of the container 31 and of the stopper 34 due to the presence of the groove 37.
  • the ring 42 constitutes an extension of the shield of the composite internal wall 33 by forming a flange facing the interior of the container.
  • FIG. 4 is a partial sectional view showing a second embodiment of the invention.
  • the container consists of a container 43 closed by a plug 44.
  • the container has an envelope 45 and a composite internal wall 46 forming a tank.

  • the stopper is provided with a metallic coating 47 forming connecting means intended to cooperate with means for connecting the container constituted by an annular element 48 integral of the tank 46 and which also forms a seat for the plug.
  • the metal coating 47 is bowl-shaped and provided with a peripheral flange 49.
  • the side wall 47a of the bowl 47 forms a centering member when the plug is placed on the container.
  • the stopper 44 and the casing 45 delimit, when the stopper is put in place, an annular groove 50 opening towards the top of the container.
  • the connection means between the plug 44 and the container 43 are arranged at the bottom of the groove 50.
  • the flange 49 is provided at its periphery with regularly spaced holes 51 arranged opposite corresponding holes 52 formed in the annular element 48.
  • Assembly means are constituted by bolts 53 arranged so as to cooperate with nuts 54 through said holes 51, 52 for sealing the container.
