Definitions

  • the subject of the invention is a packaging for the transport of dangerous materials, this packaging being designed to ensure the containment of said dangerous materials under severe accident conditions.
  • the hazardous materials for which the packaging in question is intended include in particular non-irradiated nuclear fuel materials in solid form, namely previously conditioned powders, bars and complete fuel elements.
  • the severe accident conditions under which the packaging must be capable of ensuring the containment of hazardous materials include in particular a succession of high-speed impacts followed by a prolonged fire at high temperature.
  • Packages of the kind in question which already exist comprise one or more confinement enclosures equipped with a closure device comprising a cover the sealing of which is obtained by means of seals and tightening with the aid of screws or the like; the more severe the accidental conditions which these packages must withstand, the greater the reinforcements to be made to the closure devices, leading to an increase in the mass of the package; it then becomes difficult to ensure the resistance of the less reinforced zones, especially when there are sudden variations in the thickness of the wall, unless provision is made of additional structures of the shock absorber and thermal insulator type which, although effective, are heavy. , bulky and expensive, making transport more difficult and expensive, especially in the case of air transport.
  • the object of the invention is, above all, to remedy these disadvantages and to provide a packaging of the kind in question which, while resisting the most severe accident conditions, presents itself with dimensions and a mass facilitating transport of all kinds, in particular by air.
  • an austenitic stainless steel containment enclosure consisting of a single piece devoid of orifice and seals other than welded, having the shape of a cylinder of revolution closed at its two ends which are convex in shape, the wall of this enclosure being of substantially uniform thickness without abrupt variations including at the welds, two axial shock absorbers, each comprising a section of metal tube preferably of the same section as the above enclosure, arranged on the ends of the latter so that they are coaxial with it, - removable means suitable for securing and handling the assembly as well as, if necessary, removable means suitable for securing the hazardous materials inside the enclosure, removable means suitable for ensuring the suspension of the enclosure, removable means suitable for ensuring the radiological shielding and removable means suitable for ensuring the heat dissipation.
  • the axial shock absorbers are arranged so that they can be fitted by interlocking on the ends of the enclosure.
  • the axial shock absorbers are welded to the ends of the enclosure.
  • these shock absorbers may include reinforcements such as concentric tubes and / or spacers.
  • the removable structures of the above packaging can be fixed - by friction, - by protuberances formed by the wall, - by a box enclosing the enclosure.
  • the packaging according to the invention also has other characteristics which are preferably used at the same time and which will be more explicitly discussed below.
  • This packaging is made to contain a confinement enclosure generally designated at 1 and consisting of a single piece, made of austenitic stainless steel, in the form of a cylinder of revolution closed at its two ends which are convex in shape.
  • the thickness of the wall of this enclosure is substantially uniform without abrupt variations, including at the welds which will be discussed below.
  • the enclosure has two shock absorbers A axial each formed by a section of metal tube preferably of the same section as the enclosure, each of these tubes being disposed respectively on one of the ends of the enclosure to which they are coaxial.
  • the coaxial shock absorbers can be arranged in such a way that the enclosure-shock absorbers assembly can withstand an impact at 470 km / h on a flat and undeformable target.
  • the wall of the enclosure a thickness such that it resists a fall from a height of 3 m on a steel punch with a diameter of 2.54 cm.
  • the containment is obtained by joining, by edge-to-edge welding along S, on the one hand a first constituent element 1a comprising the largest part of the cylinder of revolution and one of the ends E1 of the enclosure , that is to say the part which must receive hazardous materials M intended to be transported and, on the other hand, a second component element 1b essentially comprising the other end E2 of the enclosure, this second element playing the role of the cover of conventional packaging.
  • the enclosure thus formed is perfectly sealed thanks to the weld S; this welding eliminates the need for any seal, but must be checked by appropriate means, in particular by radiography and / or ultrasound, after completion.
  • the enclosure has walls of approximately uniform thickness and in any case without abrupt variations even at the level of the welded ones and does not comprise an orifice; thanks to this constitution and to the presence of the shock-absorbing tubes A, it is capable of withstanding shocks by absorbing the kinetic energy of the corresponding impacts by progressive plastic deformation of the assembly.
  • the thickness of the wall of the enclosure when the thickness of the wall of the enclosure is not uniform, it preferably varies continuously, the ratio between the thickest zone and the thinnest zone not exceeding 2.
  • the ends E1 and E2 of the enclosure 1 form domed bottoms which may be hemispherical, elliptical, in the form of basket handles and the like.
  • shock-absorbing tubes A are arranged coaxially with the enclosure on the ends of the latter by welding or by interlocking.
  • the damping tube proper A then being adaptable on the end of the enclosure by a tube element A1 coaxial with A and of internal diameter such that this element A1 can fit on the end of the enclosure with a minimum of play, its fixing being ensured by pressure screws 13 tightened against the wall of the enclosure.
  • the shock-absorbing tubes A can be reinforced by coaxial tubes of smaller diameter, not shown, housed inside the tubes A and connected to the latter, for example by fins.
  • an enclosure 1 suitable for housing a PWR fuel assembly with a mass of 750 kg, a length of 4.1 m and a square section of 215 mm on a side is in the form of a cylinder of revolution in austenitic stainless steel with a diameter of 380 mm, a length of 4.6 m and a wall thickness of 25mm, extended at each end by a damping tube of the same section, the same material and a length of 600mm.
  • the assembly has a mass of 2.5 t and withstands an impact at a speed of 470 km / h followed by a fall from a height of 3 m onto a steel punch with a diameter of 2.54 cm.
  • a fundamental advantage of the enclosure comprised by the packaging according to the invention resides in the fact that its replacement after each use can be envisaged at a lower cost because of its simple constitution, its ease of supply, its reduced mass and the possibility of recovering the removable appendages provided for its handling, stowage, suspension, blocking of its content, its shielding, etc. ; what makes this advantage even more decisive is that, moreover, the constituent elements of this enclosure can also be recovered, by means of a process in accordance with the invention which comprises a set of simple operations which will be more explicitly discussed.
  • the constituent material of the containment for packaging in accordance with the invention is austenitic stainless steel because of the well-known properties of this material from the point of view of corrosion resistance, weldability, absence of brittleness at low temperatures, high mechanical properties including elongation at break, high melting temperature.
  • the packaging includes removable means for wedging hazardous materials M inside the enclosure.
  • removable wedging means can be produced by means of members linked by friction to the enclosure, in order to prevent the wall of the latter from exhibiting zones of least resistance, in the event of impact.
  • the rigid structure schematically represented in K, and on which is fixed a complete combustible element not shown and constituting the dangerous substance M is wedged between, -
  • a spacer 4 made of malleable metal such as aluminum whose shape is complementary to that of the bottom of the end E1 of the first component of the assembly in which it is arranged and against which the spacer corresponding end of the rigid structure K is supported along 4a and - on the other hand, a blocking system, generally designated at 5, fixed to the enclosure by friction and which will be described, a spacer 6 similar to the spacer 4 being preferably housed in the end E2.
  • the reaction of the blocking system can be collected by protuberances from the enclosure, the latter possibly being in the form of a continuous or interrupted ring (bayonet system) welded against the enclosure, the total thickness of the ring not exceeding the thickness of the wall of the enclosure.
  • the bottom of the ends E1 and E2 is curved, the spacers 4 and 6 having a complementary curved shape, thanks to which in the event of an impact at the end the pressures are better distributed .
  • the locking system 5 comprises a split conical ring 7 cooperating with a setting stop 8 which applies the split ring against the interior surface of the enclosure 1 under the action of axial screws 9 , thus immobilizing the assembly 5, wedging screws 10 being provided to immobilize and center the rigid structure K on which the fuel element is fixed by reaction against the face Ka of this structure on which they are supported.
  • the packaging includes removable means suitable for securing and handling the assembly, as well as, if necessary, removable means suitable for suspending the enclosure, removable means suitable for ensuring radiological shielding and removable means capable of ensuring heat dissipation.
  • the means suitable for allowing the handling and securing of the enclosure 1 can be constituted by elements 11 which are advantageously carried by a tube or by an external ring 12 applied against the enclosure and immobilized with respect to the latter by friction, in particular by clamping screws 13.
  • the outer ring 12 may, as shown, be a constituent part of the tube A1.
  • the enclosure 1 can be maintained inside a frame or support shown in FIGS. 2a and 2b and generally designated at 14, keeping it inside said frame advantageously by means of elastic connecting elements which can be constituted by elastomeric blocks or, as in the embodiment shown in FIGS. 2a and 2b, by springs 15 and damping devices 16 of the kind used for the suspension of road vehicles, axial stops Ba and radial Br fixed to the frame limiting the amplitude of the possible deflections, taking over from this suspension in the event of a brutal shock.
