Definitions
- the invention relates to a packaging designed to allow the safe transport of parcels dangerous, requiring extreme, safe confinement, reliable and controllable.
- the package according to the invention is particularly suitable for the transport of parcels high-level nuclear weapons whose sealing is not not certain. However, it can be used to transport dangerous packages of a different nature, especially from the chemical industry.
- Nuclear laboratories and factories produce waste that is classified according to their level of activity, before being transported to their respective storage sites. To facilitate their subsequent transport and storage, waste each category are packaged in drums, for constitute "nuclear packages". The conditions in which is carried out conditioning make random and uncertain package sealing.
- transport casks The transport of nuclear packages from their production sites up to their storage sites in packaging, usually called “transport casks", which must ensure both effective containment of nuclear material transported and the biological protection of and the environment. These packages must also have a shock and fire resistance to preserve confinement in all circumstances that is to say, especially in the event of an accident during transport of the packaging and in the event of a fall during its handling. Packaging must also ensure efficient evacuation of the heat released by the nuclear material.
- nuclear waste are sorted into low, medium and high level waste activities, which are packaged separately to form three types of nuclear packages.
- These three types of nuclear packages are transported in packaging different, which must meet the requirements all the more severe as the activity of the parcels transported is high.
- the packages are designed to receive a number too as much as possible of parcels, in order to limit the number of trips between the waste production site and the storage site.
- all packaging intended to carry nuclear packages include several dwellings, called “alveoli”, intended for each receive one or two packages.
- the external dimensions packaging are independent of the nature of the parcels transported and fixed by the maximum gauge allowed during transport.
- the thickness of the biological protection is significantly lower in the case of low-level waste than in the case of high level waste.
- a transport packaging having four juxtaposed cells each of which is sized to receive a single nuclear package.
- These cavities are formed in a cylindrical body mainly made of a protective material biological, coated with a steel shell over its entire outer surface as well as inside the cells.
- the cells all open on the upper face, substantially flat, of the body and they are normally closed by individual caps containing also a biological protection material. All the caps are capped globally by a lid single, removably attached to the upper side the body of the package.
- a hood ensuring the shock protection and heat dissipation, overflows the entire upper surface of the body on which the lid has been fixed.
- the containment is controlled by connecting the space located between the seals to means of depression. We then monitor, for a relatively long time, the evolution of the pressure in this space, in order to determine the leak rate.
- This containment control technique dictated by the design of the transport packaging existing, has the disadvantage of being particularly long. Moreover, it translates, at the time of the tests sealing, by transfer of contamination to the outside is all the more important as the rate of leak is high.
- this current technique of containment control does not detect a possible leak in the lower part of alveoli.
- the lack of control at this level is all the more regrettable that the inner envelope in steel, which delimits the cells, presents a welding as a possible source of leaks.
- GB-A-2 166 680 packaging for long-term storage irradiated fuel assemblies, previously stored in pool for about 10 years.
- This packaging includes a cylindrical body delimiting internally square section housing. Two overlapping plugs are attached to stepped staves of the body, after which an intermediate lid is welded to said body and a closure lid is put in place.
- the inner cap cooperates with the body by a first seal and the second plug cooperates with the body by two other joints sealing. Passages allow, on the one hand, to inject helium between the two plugs and, on the other hand, to detect a possible leak between the two joints of the second stopper.
- the subject of the invention is mainly a dangerous package transport packaging, including the original design allows to carry out a control rapid containment, avoiding any transfer of outward contamination when control is made.
- a package transport package dangerous characterized by the fact that it includes a body internally delimiting at least one cell which leads to the same face of the body, corks individual filling of each cell, and a cover covering the plugs and cooperating with said face by external seals, intermediate and inner encircling simultaneously all caps, the lid being provided with a first connection, capable of being connected to a source of tracer gas under pressure and opening between the joints internal and intermediate sealing, and second connection, capable of being connected to means of depression and detection of the tracer gas, and opening between the intermediate seals and outside.
- This arrangement makes it possible to perform a rapid containment control without risk of transfer of contamination to the outside since the space put in depression, is separated from the cells by two seals in series.
- the presence of three seals in series significantly improves the quality of containment.
- the limit leakage rate can be lowered to 10 -8 Pa.m 3 / s.
- each cell is preferably delimited by a metal envelope inside, usually made of steel, with at least a weld, doubled by a metal shell exterior, usually copper.
- the double envelope thus constituted around each cell can then be used to locate the cell or cells with a weld faulty, when the overall containment control, made using the two fittings placed on the cover, reveals an unacceptable leakage.
- the body of the packaging is then equipped externally with third fittings able to be connected to a source of tracer gas under pressure and piping connect each of the third fittings to the outer metal shell of one of the alveoli, so as to emerge nearby the welding of the inner metal shell.
- the third fittings are preferably mounted on the aforementioned face of the body, beyond the cover.
- outer metal envelopes preferably copper
- adjacent cells are connected together to others by heat dissipation plates made in the same metal.
- the confinement is preserved in the event of a fall or an accident, by equipping the packaging of a removable damping hood on the face aforementioned body and a removable damper bottom on its opposite face.
- the removable damper hood as well that the removable damping bottom are formed at least partly stacked balsa. They can also understand structures in honeycombs progressive.
- the body of the present packaging generally a cylindrical shape, of given axis, and the cells are regularly distributed around this axis.
- the gripping organs of the packaging are then mounted, preferably, on a peripheral wall of the body, in planes passing through the axis of this last and located between the cells. This provision prevents the cells from being damaged in case of falling of the packaging on one of the organs of gripping.
- the aforementioned face of the body of the package is formed partly on a metal flange that encircle the alveoli and on which is fixed the lid.
- the peripheral wall of the body is further materialized by a metallic shirt, one edge, placed on the aforementioned face of the body, is connected to the flange by a deformable sheet in case of shock. This The arrangement helps, again, to preserve the containment of the packaging in the event of a fall or accident.
- the packaging according to the invention is particularly suitable for transport of high-level nuclear packages, even if it can be used to transport parcels dangerous of different natures such as parcels from the chemical industries.
- body and plugs include a lead biological protection, which completely surrounds the alveoli.
- the biological protection of the body is then separated from its peripheral wall by a space filled with concrete.

- the plate of closure 30 is fixed on the flange 18 by a screw 32 disposed along the axis of the body 10.
- a lid 34 completely covers the plugs 28 and the closure plate 30 on the face upper body 10. More specifically ( Figure 3), the lid 34 is fixed by screws 36 on the flange 18 materializing the upper face 17 of the body 10, and it cooperates tightly with this face 17, by three concentric circular seals, which simultaneously encircle all the plugs 28, so to ensure global containment of the cells 22.
- the screws 36 are arranged outside the joints sealing, relative to the axis of the body 10.
- the three seals include a seal outside 38, an intermediate seal 40 and a seal 42.
- the seals 38, 40 and 42 are o-rings that are received in throats concentric formed on the face of the lid 34 intended to be applied against the upper face 17 of the body 10.
- the cover 34 carries a first connection 44, accessible on its upper face, and which opens in an annular space 47 formed between the joint internal sealing 42 and the seal intermediate 40.
- This first connector 44 is intended to be connected to an external source (not shown) a tracer gas under pressure such as helium.
