Description

Dans une usine nucléaire, on sépare par des parois et des dalles épaisses les zones contenant des matières dangereuses des zones où le personnel peut être présent.In a nuclear plant, areas containing hazardous materials are separated from areas where personnel may be present by thick walls and slabs.

La zone dangereuse est généralement appelée zone active. On peut y trouver des produits radioactifs émetteurs y ce qui justifie l'épaisseur des parois et/ou des produits radioactifs émetteurs a et p considérés comme contaminants. Tout matériel sortant d'une zone active est considéré comme contaminé et doit être placé derrière une paroi épaisse (pour protéger des rayons gamma) et dans une enceinte étanche (pour ne pas répandre la contamination).The danger zone is generally called the active zone. You can find radioactive emitting products there which justifies the thickness of the walls and / or radioactive emitting products a and p considered as contaminants. Any material leaving an active area is considered to be contaminated and must be placed behind a thick wall (to protect from gamma rays) and in a sealed enclosure (so as not to spread contamination).

Quand un matériel présent dans la zone doit être remplacé, ou sorti, pour être amené dans une cellule d'intervention pour dépannage, et de même quand on veut remettre en place le même matériel, il est impératif de conserver un confinement total pour éviter de répandre la contamination. Il est également impératif de conserver une épaisseur de paroi suffisante pour la protection biologique entre ce matériel et le personnel pendant le déplacement vers la cellule d'intervention.When equipment present in the area must be replaced, or taken out, to be brought into an intervention cell for troubleshooting, and similarly when we want to replace the same equipment, it is imperative to maintain total containment to avoid spread the contamination. It is also imperative to keep a sufficient wall thickness for biological protection between this material and the personnel during the movement towards the intervention cell.

Une cellule amovible pour la manutention des pièces irradiées est décrite dans le brevet FR-A 2 462 769.A removable cell for handling irradiated parts is described in patent FR-A 2,462,769.

La présente invention décrit un procédé permettant le transfert d'un "objet" tel que matériel, pièce de machine, fût de déchets, etc... de la zone active à la zone propre, le transport dans la zone propre de cet objet, et le transfert en sens inverse de la zone propre à la zone active en respectant les impératifs de confinement et de protection biologique.The present invention describes a process allowing the transfer of an "object" such as material, machine part, barrel of waste, etc. from the active zone to the clean zone, the transport in the clean zone of this object, and transfer in the opposite direction from the clean zone to the active zone while respecting the requirements of confinement and biological protection.

Une des caractéristiques de l'invention est d'utiliser pour conserver le confinement un dispositif en deux parties une préenceinte fixe et une enceinte mobile.One of the characteristics of the invention is to use a device in two parts to keep the confinement a fixed pre-enclosure and a mobile enclosure.

Le préenceinte reste en place pendant tout le temps nécessaire pour extraire un objet, l'emmener dans une cellule et ramener soit un autre objet, soit le même réparé, et le transférer dans la zone active.The pre-enclosure remains in place for the entire time necessary to extract an object, take it to a cell and bring back either another object, or the same repaired item, and transfer it to the active area.

Pour décrire l'invention, on raisonnera sur une cellule active accessible par son plafond en opérant les transferts verticalement.To describe the invention, we will reason on an active cell accessible by its ceiling by operating the transfers vertically.

Le même procédé s'applique en fait à toutes les dispositions géométriques telles que transfert à travers un mur vertical ou transfert à travers le plancher.The same process applies in fact to all geometric arrangements such as transfer through a vertical wall or transfer through the floor.

On considérera donc une cellule active dont le plafond est une dalle horizontale comportant un bouchon.We will therefore consider an active cell whose ceiling is a horizontal slab with a plug.

La face supérieure du bouchon est propre et doit le rester. La face intérieure du bouchon est dans la zone active et est considérée comme contaminée et contaminante.The top side of the cap is clean and should be kept clean. The inside of the cap is in the active area and is considered to be contaminated and contaminating.

L'objet, au moins au moment du transfert, est suspendu au bouchon. Les dimensions de l'objet sont supposées telles que en soulevant le bouchon on puisse extraire l'objet par le trou ainsi découvert.The object, at least at the time of transfer, is suspended from the stopper. The dimensions of the object are assumed such that by lifting the plug one can extract the object through the hole thus discovered.

On se reportera aux figures pour mieux comprendre la description qui suit :

  • - la figure 1 représente en coupe une cellule active ;
  • - la figure 2 représente la préenceinte en coupe ;
  • - la figure 3 représente l'enceinte mobile en coupe ;
  • - les figures 4, 5, 6 et 7 représentent en schéma la position des divers bouchons pendant l'extraction d'un objet de la cellule active ;
  • - la figure 8 montre l'objet extrait de la cellule et placé dans l'enceinte mobile ;
  • - les figures 9 et 10 montrent la remise en place des bouchons ;
  • - la figure 11 représente une variante avec cloche de protection dans l'enceinte mobile et la figure 12 représente la manipulation par chaîne poussante.
We will refer to the figures to better understand the following description:
  • - Figure 1 shows in section an active cell;
  • - Figure 2 shows the pre-enclosure in section;
  • - Figure 3 shows the movable enclosure in section;
  • - Figures 4, 5, 6 and 7 show in diagram the position of the various plugs during the extraction of an object from the active cell;
  • - Figure 8 shows the object extracted from the cell and placed in the mobile enclosure;
  • - Figures 9 and 10 show the replacement of the plugs;
  • - Figure 11 shows a variant with protective cover in the mobile enclosure and Figure 12 shows the manipulation by pushing chain.

Sur la figure 1 est représentée en coupe une cellule active composée d'une dalle horizontale 1 et de murs 2. Le bouchon 3 sépare la zone active 6 de la zone propre 7.In FIG. 1 is shown in section an active cell composed of a horizontal slab 1 and walls 2. The plug 3 separates the active area 6 from the clean area 7.

L'objet 4 à transférer est suspendu au bouchon. Le transfert se fera suivant l'axe 5 qui est supposé vertical pour la clarté de la description.The object 4 to be transferred is suspended from the stopper. The transfer will take place along axis 5 which is assumed to be vertical for the clarity of the description.

La figure 2 montre une préenceinte coupée par un plan vertical suivant l'axe de transfert.Figure 2 shows a pre-enclosure cut by a vertical plane along the transfer axis.

Les parois 10 délimitent une boîte fermée comportant deux bouchons situés sur l'axe de transfert : un bouchon inférieur 11 et un bouchon supérieur 12.The walls 10 delimit a closed box comprising two plugs located on the transfer axis: a lower plug 11 and an upper plug 12.

A l'intérieur, un chariot 14 peut se déplacer horizontalement grâce à une tige de manoeuvre 15.Inside, a carriage 14 can move horizontally thanks to an operating rod 15.

Pour simplifier on n'a représenté ni les roues ni les rails sur lesquels se déplace le chariot.For simplicity, neither the wheels nor the rails on which the carriage moves are shown.

La préenceinte a une longueur intérieure 16 telle que le passage selon l'axe de transfert soit dégagé quand le chariot est dans la position 17. On appellera par la suite gauche la position 14 et droite la position 17. Un pont 13 assure l'étanchéité entre la cellule et la préenceinte.The pre-enclosure has an interior length 16 such that the passage along the transfer axis is cleared when the carriage is in position 17. We will then call left position 14 and right position 17. A bridge 13 provides sealing between the cell and the pre-enclosure.

L'enceinte mobile est schématisée sur la figure 3. Elle a la forme d'une boîte cylindrique ou prismatique de paroi 30 parallèle à l'axe de transfert 36.The mobile enclosure is shown diagrammatically in FIG. 3. It has the shape of a cylindrical or prismatic box with a wall 30 parallel to the transfer axis 36.

La partie supérieure est fermée mais laisse passer un câble 32 avec un soufflet d'étanchéité 34. Le câble se termine par un crochet 33.The upper part is closed but lets a cable 32 pass with a sealing bellows 34. The cable ends with a hook 33.

La partie inférieure comporte un bouchon amovible 31. Un joint 35 assure l'étanchéité entre l'enceinte et la préenceinte.The lower part has a removable plug 31. A seal 35 seals between the enclosure and the pre-enclosure.

Ayant ainsi décrit la réalisation matérielle de l'invention, il est possible d'expliquer le principe de fonctionnement par exemple pour extraire un objet de la cellule.Having thus described the material embodiment of the invention, it is possible to explain the operating principle for example for extracting an object from the cell.

Sur la figure 4, on voit la position relative des matériels précédemment décrits.In Figure 4, we can see the relative position of the materials previously described.

Nous conserverons les mêmes numéros pour désigner les mêmes parties dans les figures schématisant le fonctionnement.We will keep the same numbers to designate the same parts in the figures diagramming the operation.

La dalle supérieure 40 de la cellule comporte donc le bouchon 41 et 1"'objet' à transférer 42 suspendu sous le bouchon.The upper slab 40 of the cell therefore includes the plug 41 and 1 "object" to be transferred 42 suspended under the plug.

La préenceinte 43 est placée sur la dalle de manière à respecter l'axe de transfert.The pre-enclosure 43 is placed on the slab so as to respect the transfer axis.

Le bouchon 44 et le bouchon supérieur 46 sont en place. Le chariot 45 est en position gauche.The plug 44 and the top plug 46 are in place. The carriage 45 is in the left position.

L'enceinte 47 est posée sur la préenceinte de manière à respecter l'axe de transfert.The enclosure 47 is placed on the pre-enclosure so as to respect the transfer axis.

Le bouchon 48 est en position. Le crochet est représenté par 49.The plug 48 is in position. The hook is represented by 49.

On notera que volontairement on n'a représenté ni l'épaissuer des parois de l'enceinte et de la préenceinte, ni les joints d'étanchéité entre les divers composants.It will be noted that voluntarily there has been shown neither the thickening of the walls of the enclosure and the pre-enclosure, nor the seals between the various components.

La figure 5 représente la première manoeuvre consistant à solidariser deux par deux les bouchons:FIG. 5 represents the first maneuver consisting in securing the plugs two by two:

On accroche le bouchon inférieur 44 de la préenceinte sur le bouchon de la dalle 41.The lower plug 44 of the pre-enclosure is hooked on the plug of the slab 41.

On accroche le bouchon 48 de l'enceinte au bouchon supérieur 46 de la préenceinte et dépose cet ensemble dans le chariot. Un dispositif non revendiqué permet de verrouiller et de déverrouiller les deux bouchons par une tige de manoeuvre extérieure (non représentée sur la figure.The plug 48 of the enclosure is hooked to the upper plug 46 of the pre-enclosure and this assembly is deposited in the carriage. An unclaimed device makes it possible to lock and unlock the two plugs by an external operating rod (not shown in the figure.

Le but de ces accrochages est de protéger de la contaminamination les faces des bouchons qui seront visibles dans la zone propre.The purpose of these clashes is to protect from contamination the faces of the plugs which will be visible in the clean area.

On tire ensuite le chariot 45 en position droite telle que montrée sur la figure 6.The carriage 45 is then pulled in an upright position as shown in FIG. 6.

On voit en figure 7, l'accrochage du crochet 49 à l'ensemble constitué par bouchons 41-44 et l'objet 42. Le soufflet d'étanchéité autour du câble n'est pas représenté.We see in Figure 7, the hooking of the hook 49 to the assembly consisting of plugs 41-44 and the object 42. The sealing bellows around the cable is not shown.

Cet ensemble 41, 44, 42 est monté par le câble dans t'enceinte 47, la figure 8 montre cette position.This assembly 41, 44, 42 is mounted by the cable in the enclosure 47, FIG. 8 shows this position.

On déplace le chariot 45 pour l'amener en position gauche sur la figure 9, puis on remet en place le bouchon 46 à la partie supérieure de la préenceinte (figure 10).The carriage 45 is moved to bring it to the left position in FIG. 9, then the plug 46 is replaced in the upper part of the pre-enclosure (FIG. 10).

Il est alors possible de soulever l'enceinte 47 et de l'emmener ailleurs.It is then possible to lift the enclosure 47 and take it elsewhere.

Le confinement est resté total, en effet, l'enceinte 47 est fermée par son bouchon 48 et la face inférieure dudit bouchon n'a jamais été contaminé car elle a toujours été en contact avec la face supérieure également propre du bouchon supérieur 46 de la préenceinte.The confinement remained total, in fact, the enclosure 47 is closed by its plug 48 and the underside of said plug has never been contaminated because it has always been in contact with the top face, also clean, of the top plug 46 of the pre-enclosure.

Ladite préenceinte réalise la fermeture de la cellule grâce à l'étanchéité des contacts (les joints 13 de la figure 2) et grâce au bouchon supérieur 46.Said pre-enclosure closes the cell thanks to the sealing of the contacts (the seals 13 in FIG. 2) and thanks to the upper plug 46.

On n'a pas représenté les dispositifs servant à solidariser deux par deux les bouchons, (de tels matériels sont connus par ailleurs), ou à soulever l'ensemble. Les joints utilisés pour assurer l'étanchéité entre la préenceinte et la dalle (13), entre la préenceinte et l'enceinte (35),connus par ailleurs, peuvent avantageusement être des joints à triple effet. La fig. 11 représente une autre réalisation du disposition selon l'invention : A titre de variante, on peut envisager d'équiper l'enceinte mobile d'une cloche 50 coulissant juste avec des joints d'étanchéité ce qui permet d'éviter de contaminer l'intérieur de l'enceinte.The devices used to secure the plugs two by two have not been shown (such materials are known elsewhere), or to lift the assembly. The joints used to seal between the pre-enclosure and the slab (13), between the pre-enclosure and the enclosure (35), known elsewhere, can advantageously be triple-effect seals. Fig. 11 shows another embodiment of the arrangement according to the invention: As a variant, it is possible to envisage equipping the mobile enclosure with a bell 50 sliding just with seals, which makes it possible to avoid contaminating the inside the enclosure.

On peut de même faire les manoeuvres de montée et descente grâce à une chaîne de poussée "SERAPID" logée dans un tunnel fixé à l'enceinte.We can also do the maneuvers of ascent and descent thanks to a "SERAPID" thrust chain housed in a tunnel fixed to the enclosure.

La figure 12 montre une telle possibilité.Figure 12 shows such a possibility.

Un tunnel 60 fixé sur l'enceinte 47 comporte une chaîne de poussée 61 passant sur deux poulies 62-63 renvoyant le mouvement. On n'a pas représenté pour simplifier de contre poulies ou de glissières pour les maillons de la chaîne de poussée.A tunnel 60 fixed to the enclosure 47 comprises a thrust chain 61 passing over two pulleys 62-63 returning the movement. For simplicity, no pulleys or slides have been shown for the links of the thrust chain.

Ce dispositif a l'avantage de limiter la hauteur nécessaire pour les manoeuvres tout en concentrant sur l'enceinte les moyens de levage des bouchons et de l'objet.This device has the advantage of limiting the height necessary for the maneuvers while concentrating on the enclosure the means for lifting the plugs and the object.

Un tel montage est particulièrement pratique pour emmener le matériel 42 et le décharger dans une cellule d'intervention où il sera réparé ou révisé.Such an assembly is particularly practical for bringing the equipment 42 and discharging it in an intervention cell where it will be repaired or overhauled.

La description précédente a montré comment mettre en oeuvre le procédé objet de la présente invention dans le cas où l'objet est extrait verticalement et de bas en haut.The preceding description has shown how to implement the process which is the subject of the present invention in the case where the object is extracted vertically and from bottom to top.

On a déjà vu que le même dispositif fonctionnait à la verticale de haut en bas pour introduire un objet dans une cellule.We have already seen that the same device works vertically from top to bottom to introduce an object into a cell.

On transportera facilement aux autres cas :

  • - transfert horizontal par un bouchon situé sur un mur vertical ;
  • - transfert vertical par un bouchon situé sur le plancher d'une cellule ;
  • - transfert suivant un axe quelconque.
We will easily transport to other cases:
  • - horizontal transfer by a plug located on a vertical wall;
  • - vertical transfer by a plug located on the floor of a cell;
  • - transfer along any axis.

La présente invention a été décrite dans le cadre d'une industrie nucléaire mais s'applique aussi bien au transfert d'objet contaminé par des polluants chimiques ou bactériologiques qu'au transfert d'objets radioactifs.The present invention has been described in the context of a nuclear industry but applies as well to the transfer of objects contaminated by chemical or bacteriological pollutants as to the transfer of radioactive objects.
