Definitions
- the present invention firstly relates to containers for packaging and storage.
- Said containers are particularly suitable packaging and storage, with optimum filling, of waste dangerous, handled from a distance.
- the present invention also relates to a filling process such containers and its use for the packaging and storage of compacted nuclear waste.
- the claimed containers are suitable for optimized packaging and storage of all types of materials and in particular of materials which are difficult to handle, such as explosive materials, toxic, radioactive ...; the optimization having focused so much on the volume of filling (we are looking for a minimum size) only on the stability of stored materials.
- the hulls and end pieces, resulting from the shearing of the assemblies nuclear fuels are received in the same drum, specific to this type of high activity waste, at the outlet of their respective rinsers. They are then coated, as is, in a cement grout. Said grout is poured into the barrel, until filling to the brim of it. After welding of a cover safety, the drums thus filled are directly transferred to a workshop storage.
- Said compacted waste generally occurs under the shape of cylinders whose diameter is slightly smaller than the diameter useful interior of the CHA.
- Said waste may have a variable mass, especially of the order of 100 kg.
- two dimensions of the CHA are to be taken into account: on the one hand, its internal diameter which is dimensioning with respect to the diameter of the compacted waste and means for introducing said waste into said CHA and on the other hand its useful height, dimensioning with regard to the number said waste that can be packaged in said CHA.
- the intervening means are limited. Indeed, the relatively high mass of a waste compacted and the small clearance between its diameter and the minimum internal diameter of the CHA make it not possible to directly deposit said waste on the bottom said CHA by conventional mechanical means such as pliers.
- the composition of the compacted waste, at material level (mass of material ferromagnetic insufficient compared to the total mass of the waste) and its state of surface do not allow its manipulation by electromagnet. Otherwise, the intervention of an electromagnet would in itself pose a safety problem for the process.
- Such containers are of the CHA type in the context set out above. but as indicated above, the present invention is not limited to said context.
- Said containers in general, to shaped containers cylindrical or prismatic, of height h, open or liable to open for filling at their upper axial end.
- Said containers classic shape (in fact, their shape is adapted to that of the materials intended to be stored within them) have in principle, at their lower axial end, a bottom (capable of supporting the weight of stored materials) and are called to be filled, in a conventional manner, by their upper axial end. At the level of said upper axial end, they may have a cover (retractable).
- Said containers are generally cylindrical in shape, advantageously of circular cross section (they therefore advantageously consist of cylinders of revolution type CHA) but they can completely, according to variants of the invention, be of prismatic form (they then consist advantageously in parallelepipeds), be of cylindrical shape whose section is a portion of a circle ...
- the said characteristics can be incorporated into the structure of any type of container according to the prior art.
- the containers according to the invention are fitted, in their internal volume, along their axial wall (s), on substantially their entire height, locking means capable of deforming radially resiliently, by direct contact with the products introduced in their breast; said blocking means not allowing introduction and movement of said products within said containers only by forced pressing on said products (only in force).
- Said locking means capable of deforming radially from elastic way that we could qualify more simply as elastic means constitute the key elements, the essential constituent means of this invention. They are located inside the container, along its wall (s) axial (s).
- Said locking means generally consist of parts reported.
- the solution recommended by the invention to the technical problem packaging and storage of materials with optimum filling is particularly interesting.
- Said elastic means must exist and be able to exert their action over the entire filling height. By their deformation, they must allow a placement in force, without risk of gravity fall (of a significant magnitude, or of any size) of the products to be stored, whether or not they are accompanied to the bottom of the container by handling means (we have seen that in the case of compacted nuclear waste to be packaged in a CHA, the direct deposit of said waste on the bottom of the container is a priori excluded ...) and they must also ensure that these products are blocked.
- Said elastic means are called to deform, by direct contact with the products to store or stored, by friction with these. We observe a real friction during of the product being put into force (in the packaging phase) in the container (insofar as said product is set in motion relative to said container) and subsequently a contact (in the storage phase).
- the blocking means which equip the containers of the invention must prohibit any movement of products introduced completely or partially in said containers, under the action of their own weight or during handling, during transport of said containers. However, they must allow, by their elasticity, such movements (a progression of said products within them) under the action of an adequate thrust exerted on said products, especially when filling said containers.
- blocking means do not can exercise their (blocking) function only insofar as the products have a cylindrical or prismatic shape coinciding with that of container and adequate dimensions (suitable section and height, to avoid any fall, especially "across").
- Said locking means which typically equip the containers of the invention, moreover constitute means of protection of the inner envelope (wall (s), bottom) of said containers. They preserve said inner envelope by limiting or even preventing any shock between it and the products to be stored or stored, as well so when filling containers only during the handling and transport phases thereof.
- said means of blocking by optimizing their number and distribution, can ensure perfect centering of stored products.
- said blocking means or elastic means, distributed on the inner face of the axial wall (s) of the container are on a regular basis.
- the aim is to preserve the envelope as much as possible interior of said container, in particular limiting jolts during packaging and centering the stored products, in particular so as to distribute uniformly efforts.
- Said elastic means can exist in different variants. They may in particular consist of springs or spring elements. They can also consist of stops made of an elastomeric material.
- they consist of corrugated flat blades or springs, the corrugations of which are develop along their length and which are kept in position substantially vertical along the axial wall (s) of the container.
- Such blades must exert their action over the entire height of filling.
- a plurality of such blades of a length less than said height filling.
- each of said blades is long enough to cover the entire filling height.
- said springs are maintained in a substantially vertical position along the axial wall (s). They can thus exert their action over the entire filling height. They are generally kept in this substantially vertical position as far where they are secured in the upper part to the container.
- the length corresponds to the filling height.
- Said flat springs can completely remain completely free at their opposite end, in the vicinity of the container bottom. According to other embodiments, they can also partly low, be linked together, for example, by a free torus. The intervention of such means facilitates the fixing of said springs inside the container and maintains said springs applied against the wall (s) of said container. In any condition cause, said springs have in the lower part of a space allowing their elongation during their elastic deformation.
- the blocking means capable of deforming radially so elastic may consist of elements ("small pieces") of springs. he can in particular they are elements of flat springs secured to the container by a single from their ends or by their two ends. Said spring elements are arranged so that they exert their action by radial deformation.
- the first object of the present invention it is therefore proposed to new containers whose interest will not have escaped the attention of the skilled person.
- the specific interior arrangement of said containers allows them to be filled with dangerous products (explosives, toxic, radioactive %), even when handled remotely.
- Said products have a cylindrical or prismatic shape, coinciding with that of the container in which they are going to be stored, and a height h ′, less than or equal to the height h of said container.
- h ' minimum to avoid any gravity fall of the product, across, into the container.
- Said filling process can be implemented according to different variants. It is easy to implement if the products to be stored can be positioned directly in their "final” storage position with the means of handling said products. It is a more complex implementation if said objects can only be positioned, in several stages in their “final” storage position; if it is necessary to involve, for this purpose, complementary means. It all depends on the characteristics (weight, nature %) of the products to be handled.
- the products to be stored are handled using handling means such as suction cups or electromagnets - means which can be introduced into the container and therefore allow positioning direct of said products within said container.
- the first of these products is introduced into the container and positioned directly at the bottom of it with said handling means; the next possible one (s) is (are) then introduced (s) and positioned (s) thereon (successively, one on top of the other) of the same way. It is obviously planned to be able to exercise on said products, through such handling means sufficient force to overcome the friction forces exerted by the locking means.
- the products to be stored are handled by means of suitable handling such as suction cups, electromagnets or clamps - means which may or may not be introduced into the container but which in any condition according to this variant of the process, are not introduced therein - and positioned, in several stages, in the container.
- suitable handling such as suction cups, electromagnets or clamps - means which may or may not be introduced into the container but which in any condition according to this variant of the process, are not introduced therein - and positioned, in several stages, in the container.
- the products to be stored are partially introduced into said container. They are there done deposited, stably, in the upper part. Stability is acquired thanks to blocking means. They are then separated from their handling resources and kept in stable equilibrium thanks always to the locking means with which the container is fitted. They are finally completely introduced into said container under the action of other means such as a pusher cylinder.
- the means of handling being retracted, other complementary means are involved. Said other means or complementary means push each of said products to their final storage position in a single operation or grow each product, on a short run, for the sole purpose of clearing the entry of the container for the introduction of the following product. In the latter case, the stack of products which builds up as a whole, in spurts, to its position final storage.
- each product is put in place in several stages (at least 2).
- This variant of the process of the invention is advantageously implemented with mechanical handling means of the pliers type. It is ideal for filling a container of the type CHA with compacted nuclear waste.
- the method of the invention as described above is advantageously used for the packaging and storage of compacted nuclear waste. It is described in more detail in this context nuclear, with reference to Figures 3a to 3f attached.
- Figures 1 and 2 show a container of the invention.
- Figure 1 is a longitudinal section along I-I of Figure 2; said figure 2 is a section according to II - II of said figure 1. Said container is shown "filled”.
- FIGS. 3a to 3f illustrate an implementation of the method of filling of a container of the invention (block diagram).
- FIGs 1 and 2 there is shown in 1 a container of the invention. he it is a cylindrical container with circular section. In a way characteristic, it is equipped in its interior volume with five flat springs corrugated 2. Said springs 2 are joined at 3, by welding, to said container 1. They are connected together, at the bottom of said container 1, by a torus 4, left free. They develop their undulations, along their length, along the axial wall 1 ' of said container 1. The products stored within said container are shown diagrammatically at 5 container 1.
- Said container 1 is intended to be filled with compacted waste radioactive 5 or pancakes 5.
- Said container 1 is of the type shown in the Figures 1 and 2.
- Said waste 5, coming from the press, is placed beforehand on a cylindrical turntable 21 having a notch (passage).
- Container 1 of type CHA is placed below said plate 21. It rests on the jack of a lift transfer cart (not shown) (Fig. 3a).
- the gripping head 22 At the start of a cycle for introducing compacted waste 5 into the container 1, the gripping head 22 is in the high position and the turntable 21 positions said compacted waste 5 by rotation, placing it in the axis of said gripping head 22 ( Figure 3a).
- Said gripping head 22 then descends by the "N • 1 translation” system until contact with its probe assembly with the compacted waste 5, which identifies the presence of said waste 5.
- the association of the sensor with a synchro-resolver allows to measure the height h ′ of the waste 5.
- the three elastic jaws of the clamping device 23 then ensure that the waste 5 is gripped over a certain height (FIG. 3b).
- the gripping head 22 rises by the "N • 1 translation” system.
- the turntable 21 rotates to present its passage notch under said head 22, thus leaving free access to the container 1 which is located below said turntable 21 and in the axis of the head 22 (FIG. 3c) .
- the gripping head 22 provided with the compacted waste 5 then descends by the "translation N • 1" system to a predefined height and partially introduces said compacted waste 5 into the container 1, along its longitudinal axis ( Figure 3d).
- the gripping bracket measures the space still available in said container 1 using the probe assembly and of the push cylinder 24, within the limit of the latter's travel.
- a CHA container has a ferrule at the top (the diameter inside of the ferrule flange is 400 mm) and a useful height of about 1 m. It is used to store compacted nuclear waste (wafers resulting from compacting of shells and tips in a case).
- Said container is equipped with locking means according to the invention.
- the said means have the function of blocking waste compacted during the filling phase, when no thrust is exerted on the last waste introduced, as well as during the phases of handling and transport of CHA. Said means also protect, during these two phases of use of the container, its inner envelope.
- Said locking means consist of five wavy flat springs maintained in a vertical position along the inner wall of the CHA. They are evenly distributed along the shell, every 72 ° (the waste stored are thus perfectly centered). Each of said springs is fixed in the upper part of the CHA by welding on the ferrule. The five springs are connected by a free torus in lower part of the CHA.
- This container can in particular be filled according to the second variant of the method of the invention, specified above and explained with reference to FIGS. 3a to 3f.
- h ' greater than h' minimum
- h ' minimum D 2 -d 2 ; D representing the internal diameter of the CHA and d the diameter of the waste).
