Definitions

  • the present invention relates to a structure and a method for storing high-level radioactive materials by using a dense asbestos-cement.
  • the effluents will be brought, if they are not already so, in a solid form and they will be coated in a suitable solid matrix capable of withstanding the mechanical, physical or chemical aggressions coming from the radioactive materials themselves. - same or from the outside environment.
  • the effluents dispersed in said solid matrix will be "conditioned” so as to be able to be preserved for more or less long periods which will be necessary for the development of the radioactive material, then for the proper storage of said material.
  • the present invention firstly consists in the choice of a suitable material which can be used for the storage of radioactive effluents dispersed in a solid matrix.
  • dense asbestos cement that is to say by definition in the present application an asbestos cement with a density greater than 1.75 g / cm 3 ) recognizes the material of choice for the constitution of tubes and connection sleeves used for the storage of radioactive products.
  • the asbestos cement chosen is a material with a high dosage of cement (of the order of 1,500 kg per cubic meter), a fine grain size due to the mixture of approximately 85% of cement having approximately 3,000 to 4,000 cm 2 / g of BLAINE specific surface and about 15% of asbestos at 20,000 cm 2 / g and a density greater than about 1.75 g / cm obtained thanks to the application at the head of the formative machine of a high compression favoring the bonding and densification of successive layers of material.
  • the values given above are average values. Those skilled in the art will be able to adapt, 2 on the one hand, the starting materials and, on the other hand, the processing conditions for obtaining an acceptable material for the intended application.
  • German patent No. 1,136,261 describes the use of a refractory binder material of complex composition based on calcium sulphate mixed with asbestos, but does not describe the use of a dense asbestos-cement as in the present application.
  • French Patent No. 1,347,402 describes the use of a filling material which consists of fibers impregnated with an adhesive and then compressed in the space between two containers; the material used in French patent n ° 1 347 402 is therefore not dense asbestos-cement as in the present application and does not play the same role with regard to radiation.
  • the storage structure according to the present invention is characterized in that it consists of pipes of standard length, very thick, made of dense asbestos-cement, said pipes being arranged vertically next to each other, between said pipe lines the cooling air circulates, the said pipes being connected to each other using dense asbestos-cement sleeves.
  • vitrified waste consists of cylindrical glass blocks, 400 to 500 mm in outside diameter and 1,500 to 2,000 mm in total height. Their unit heat release can reach a few kilowatts at the start of their storage period.
  • the dense asbestos-cement tubes according to the invention are therefore used for carrying out intermediate storage of high activity effluents, said tubes serving to fractionate the mass of the products to be stored and to guide the cooling air around said products.
  • the entire repository will be in the form of a buried building, preferably of vertical cylindrical shape, comprising a bundle of dense asbestos-cement tubes, of triangular or square mesh.
  • the design is based on the use of standard length pipes in pressure class, very thick, the pipes being connected to each other using dense asbestos-cement sleeves. These sleeves will also serve as spacers, at different levels, with a shift from one tube to another, so as to constitute a rigid and compact structure, resistant to the forces and stresses resulting both from the load, the temperature and the seismic constraints.
  • the sleeves of two neighboring tubes will be offset by a third of the length, so as to provide suitable bracing.
  • the sleeves of two adjacent tubes will be offset by half a length of tube.
  • the space between the tubes will serve, at least for part, for the descent of the fresh air along the wells, this same cooling air then rising inside the tubes, in the annular space left free between the glass containers and the inner wall of dense asbestos-cement tubes.
  • the heating of the air during the descent is sufficient to allow the dew point temperature to be exceeded at the start of air licking of the containers, thus avoiding any risk of corrosion of the stainless steel glass containers.
  • the speed of ascent of the air of the order of 2 m / s, is substantially the same as that chosen for the descent between the tubes.
  • the hot air will come out at a temperature of around 200 ° C at the top of the storage.
  • An air mattress formed by the incoming fresh air provides protection for the concrete parts on the upper surface of the storage and on the outer shell.
  • a square mesh storage also makes it possible to obtain very good results from the point of view of the compactness of the storage.
  • the core glass temperatures remain below 400 ° C., therefore clearly below the critical recrystallization temperature.
  • their highest wall temperature remains below 200 ° C, which is significantly below the permissible limits.
  • Guiding the containers inside the asbestos-cement tubes can also be carried out with dense asbestos-cement elements (plate elements fixed inside the tubes for example), without this being a compulsory solution.
  • Other variants are possible such as, for example, containers provided with metal guide fins, or even by fixing parts. metal, noble metal, adapted and fixed on pipes or on glass containers.
  • the preferred cylindrical shape for storage makes it possible, if necessary, to partition it into sectors, and to circulate the arrival of cold air from the periphery towards the center.
  • Such a type of storage can be just as suitable for transient cooling of the glasses, for a few years after their production, as for longer cooling, while waiting for their final storage in a geological structure.
  • Such a fractionation structure can also be adapted to the storage of dissolving shells or fines after solidification and placing in a container.
  • the storage silo 1 consists of a closed concrete enclosure 2 in which are arranged a series of columns 3, 3a, 3b made of dense asbestos-cement.
  • Each of these columns consists of a stack of superimposed unit tubes 4, 4a, 4b, 4c.
  • the junction 5 between two tubes is shown in detail in FIG. 5.
  • the tube 4a rests end to end on the lower tube 4b by means of a seal 6 held in the circular groove 7 of the connection sleeve 8.
  • connection sleeves are offset by a height corresponding to a half-height of unitary tubes on two adjacent columns.
  • a sleeve is only in contact with the four adjacent columns and never with another sleeve. Consequently, the sleeves also act as a spacer between adjacent columns.
  • each column is closed by a plug 11, 11a, 11b housed in the corresponding openings of the slab 12 of reinforced concrete.
  • the cap plus slab assembly provides protection between the intervention zone 13 located above the silo and the interior of the enclosure 2.
  • each column rests on a base 14 formed by a double row 15 and 16 of adjacent support sleeves 15a, 15b and 16a, 16b whose average diameter is equal to ⁇ 2 times the square mesh of the network made up of all the columns.
  • the bottom 17 of the columns has a stool 18 formed by a blank made of dense asbestos-cement.
  • This bottom can be fitted with a container fall-arresting device such as, for example, that described in French patent application No. 81 02 882 filed on February 13, 1981.
  • the storage containers 19 are stacked on top of each other inside the columns, their centering being able to be achieved by guide fins not shown in the figures and arranged radially inside the columns.
  • the fresh air is distributed at the top of the enclosure thus protecting the upper concrete slab and enters the isthmus 20, 21 formed between adjacent columns or between the columns and the side walls of the enclosure by means of asbestos-cement intake tubes 22.
  • These tubes 22 are held by two plates 23 and 24 made of asbestos-cement, these plates resting on the corresponding sleeves 25, 25a, 25b of the neighboring columns and delimiting an enclosure 26.
  • the double row 15 and 16 of support sleeves of the base ensures better protection of the concrete raft 27 and a better distribution of air at the lower part of the silo.
  • the hot air opens into the enclosure 26 through the lights 28, 28a formed in the part of the columns passing through the enclosure 26. These lights can be more or less obscured by an appropriate adjustment device not shown, for example by a cover. Horizon sliding in the pierced part of the column and actuated in the intervention zone 13 by means of a rod sealingly passing through the plug.
  • the columns are arranged in a square mesh network, the two diagonals D l and D 2 are respectively parallel to the walls P 1 P ' 1 and P 2 P' 2 of the enclosure .
  • the network is made up of two sets of columns.
  • a first assembly 29 is constituted by the row of columns 30, 30a and 30b in contact with the walls P 1 and P ' 1 , P 2 and P' 2 .
  • These columns do not include a container, are swept by a downward flow of fresh air and act as a spacer between the walls of the enclosure and the columns of the second set 31 of columns which contain the containers. It is noted that, in the case shown, the four corners of the enclosure are cut to maintain the rigidity of the assembly. This gives excellent cohesion and therefore good resistance to earthquakes.
