Definitions

  • the invention relates to a scalable structure which constitutes a sealed enclosure. It applies in particular to the realization of a nuclear equipment dismantling workshop. It can also be used for storage, or in a non-hostile environment.
  • the dismantling of nuclear equipment consists of dismantling or cutting pipes and equipment contaminated by radionuclides. In order to avoid the spread of this contamination, these operations are carried out in a confined enclosure called an intervention workshop, built around the equipment to be dismantled.
  • a confinement barrier is created during intervention operations in a contaminated medium by means of a flexible wall supported by metal masts or a metal frame consisting of an assembly of tubes or even a pneumatic frame of so as to make a kind of tent whose walls are glued and which isolates the equipment to be dismantled.
  • the main drawback is that in the event of a fire, the vinyl walls are destroyed and the containment function is no longer ensured.
  • the metal or pneumatic masts and frames present inside the intervention workshop form recesses which are places of retention of contamination and hinder decontamination.
  • the known enclosures do not allow one or more elements to be interchanged during assembly and after decontamination of the workshop, or even during operation, to modify the initial architecture.
  • the known intervention workshops do not include biological protection.
  • RENARI also known (GB-A-791706 (RENARI)) is a square or rectangular panel having a shaped periphery so as to allow the assembly of several similar panels, so as to form various structures.
  • Each side of the panel has a rectangular flange perpendicular to the plane of the panel.
  • the edge of the panel has holes that allow them to be fixed.
  • Triangular or longitudinal or U-shaped connecting elements are provided.
  • the border of the panel is interrupted. This panel is therefore not likely to constitute a confinement enclosure.
  • the problem of sealing between the panels has not been considered.
  • FR-A-2201375 NURMI-NEN
  • IT consists of a steel sheet covered with a layer of plastic material, the longitudinal edges of which are folded twice at 90 ° to form a rim with a U-profile.
  • the panels are assembled by heating the plastic coating so as to melt it.
  • the profile of the border of these panels is not continuous so that they are not suitable for producing a sealed containment enclosure.
  • the connection between two panels is not removable, so that they do not allow for a scalable structure.
  • the object of the present invention is precisely to remedy these drawbacks of the prior art by creating a modular modular structure of containment composed of panels.
  • the panels must be removable so that a panel of a given type can be replaced by a panel of another type, or so that the dimensions of the structure can be varied at will by adding additional panels or by removing.
  • the structure must make it possible to constitute a perfectly sealed enclosure, in particular for the application to the creation of a containment barrier for nuclear equipment to be dismantled.
  • each panel can be easily dismantled and replaced by a panel of another type.
  • a seal is ensured between the panels thanks to the presence of said first wings and to the presence of a flexible plastic and non-flammable seal. Sealing remains assured even in the event of fire.
  • some of said panels have a central opening, a plexiglass or metal plate being fixed to the opening by bolting on the face of the panel 4, a seal being interposed between the face and said closure plate, this plate supporting equipment such as a viewing window, glove rings, fluid passages, a remote manipulator, a container docking flange.
  • said second wings are bolted to posts, beams, hexagonal plates or T-shaped sections to improve the rigidity of said structure.
  • I-shaped profiles are fixed vertically on the second wings of the folded edges and a biotogic protection consisting of a stack of bricks, plates or boxes, is placed parallel to the panels and between the I-sections.
  • FIG. 1 represents a perspective view of an intervention workshop designated by the reference generate 1. It is made up of assembled panels which constitute both the vertical walls and the horizontal ceiling 6 of L'ateLier. These panels are standard panels such as Panel 2 or frame panels such as panel 4 which has a central opening 4a which makes it possible to attach plexiglass or metal plates to equipment such as a viewing window, rounds of glove 5, passages necessary for connection of ventilation 7, utility passages, the docking flange of a container, for example such as that described in document FR-A-2418 527.
  • the edges of the panels are folded twice at right angles and welded in The angles.
  • the structure of the panels is reinforced by a diamond point folding 10 made with the sheet bending machine.
  • the wings 8a and 8b of the U-shaped profile have fixing holes referenced respectively 9a and 9b.
  • the holes 9b of the border 8b allow the panels to be fixed together so that their surfaces located inside the enclosure are at the same level. This facilitates decontamination operations during and at the end of operation, because the interior faces of the panels are as smooth as possible without grainy coating or sharp corners.
  • the wings 8a of the panels have holes 11 which allow them to be fixed to an external stiffening system (see FIG. 4).
  • the holes in the border 8b also allow the fixing of the panels to the floor, to the vertical walls and to the ceiling. It is made up of connecting elements and corner pieces.
  • the edge of the panels also allows the installation of seals.
  • the panels are rectangular or square.
  • the standard panel measures 0.80 m x 1.60 m but there are also panels of 0.40 m x 1.60 m, 0.80 m x 0.80 m and 0.40 x 0.80 m.
  • connection of two perpendicularly mounted panels is carried out by means of corner pieces ( Figures 8 and 10).
  • the corner piece is bolted to each panel. It is made up of a L-shaped sheet. Its Length is a multiple or a sub-multiple of The length of a module.
  • the panels can also be connected by a corner piece with four or five faces in ptied and welded head ( Figures 5 to 8 and 10).
  • the frame panels make it possible to adapt a large number of equipment.
  • a waterproof single leaf door is mounted on a frame that can be adapted in place of two or more standard panels. The whole is called panel-worn.
  • One of these doors is equipped with an anti-panic opening system, that is to say a door comprising a large handle and opening from the inside to the outside.
  • We can also adapt to the frame panels a door or a hatch used for the entry of the material to be dismantled.
  • the doors or the hatches for the equipment are single-leaf sealed. They are mounted in 1.6 x 2.4 m frames.
  • the waste from the dismantling workshop is evacuated by an airlock which allows waterproof docking by plating a 200-liter petroleum drum on the waste evacuation system or by placing it on a flange panel. docking described in Patent FR-A-2 418 527.
  • the gloves which equip the lateral faces of the airlock make it possible to fill the barrel, crimping the cover and helping to position the barrel, Installing or removing the cover.
  • the ventilation keeps the airlock in dynamic tightness.
  • the maneuvering box of the cover acts as a transfer duct for the outside air to the intervention workshop to avoid contamination of the mechanics of the waste evacuation system.
  • the airlock can also be equipped with a bag round of 1000 mm in diameter which allows the exit of large-scale waste under welded vinyl.
  • seals The watertightness of the modular panels between they are made using seals.
  • These seals can be plastic seals with silicones such as Gebsicon or Le Robson transtucide.
  • Said first wings 8b of the panels are assembled together in a leaktight manner by a flexible, non-flammable plastic silicone seal.
  • Each of said first wings 8b is coated with each of the panels to be assembled with silicone.
  • These wings are assembled by bolting. We remove the excess seal that smeared when tightening the two panels. A certain amount of seal is added along the edge of the two panels located inside the confinement enclosure, then a protective adhesive strip is placed over it. After assembly of the workshop, an adhesive strip is stuck on the angles of the modular cell.
  • This strip facilitates the decontamination of workshops by smear or spraying with dilute nitric acid or conventional detergents.
  • the sealing between the frames and the panels of these frames is achieved by means of O-rings.
  • the edges of the panels are bolted to a connecting element overlapped in the ground, vertical walls or ceilings.
  • the connecting element 9 is fixed to a civil engineering structure 14 by a dowel 16.
  • the diameters of the bolts and dowels are identical to facilitate mounting.
  • the connecting elements 9 constituted by metal belts make it possible to make up for the faults of civil engineering, that is to say floors, ceilings and walls.
  • the installation of these elements must be done before mounting the panels. They consist of a sheet of stainless steel folded twice at right angles.
  • One of the branches is placed on the ground.
  • the other branch supports the panel ( Figure 4).
  • Their Length is a submultiple or a multiple of the length of a standard panel.
  • the panels can, if necessary, be maintained by a frame.
  • This frame is then built outside the workshop and can be adapted to its dimensions. It will be made up, for example, of profiles or lattice girders.
  • the connecting elements at right angles to the sectional panels shown in Figure 5 allow the dimensions of the workshop to be extended.
  • One element has folded U-shaped edges, the wings 18a, 18b of which are provided with fixing holes 19b, allowing them to be fixed to the panels and possibly holes 19a allowing them to be fixed to an external stiffening system.
  • the posts or the beams are fixed on the civil engineering, like the belts, by means of dowels and buttoned on the folded side of the panels. They optionally serve to fix the biological protections 20 shown in FIG. 9.
  • An intervention workshop carried out using modular panels of the invention has many advantages.
  • the self-supporting structure of the workshop and the modularity of all of its metal panels and accessories allow one or more elements to be exchanged with one or more others both during assembly. and during operation only after decontamination of the workshop to modify its initial architecture.
  • Plexiglas or metal panels can be tightly fixed, for example using clamps, on a frame adapted to allow vision, assistance to operators by glove rings, the exit of small materials under vinyl or trash cans DTPE La Calhène, The connection of air transfer or extraction circuits of Ventilation, Connections of service fluids and electrical circuits, connections of electrical safety systems such as Detection systems and safety fluid distribution circuits such as fire extinguishing, breathing air, emergency lighting, etc.
  • An important advantage of the invention lies in the fact that the design of the panels with structure turned towards the outside makes it possible to have an internal surface free of any structure capable of becoming a place of retention and discomfort for decontamination.
  • the dismantling workshop is made of stainless steel to avoid corrosion of the panels, but it can be done in any other metal or material in particular in self-extinguishing composite materials.
  • roof hatches of identical design to that of the doors which allow the evacuation of heavy parts or of large dimensions such as the biological protections of the ⁇ - ⁇ armored cells. made up of cast iron or lead plates, Workshop machines, etc ...
  • FIG. 6 There are shown in Figures 6 and 7 two embodiments of a connecting element for connecting three walls in a scalable structure according to the invention.
  • Element 40 (FIG. 6) has four walls, namely two complete square walls and two other walls made up of squares of which a corner has been cut. Each of these faces is pierced with a hole which allows its fixing by bolting to the second wings 8a of the panels.
  • connection element 42 (FIG. 7) consists of a cube from which one of the faces has been removed. It thus has five square walls each having a hole which allows it to be bolted to the second wings 8a of the panels.
