摘要： Device (1) for packaging nuclear waste, comprising a concrete container (3) the internal wall of which delimits a cavity in which a metal vessel (2) is housed, the device being characterized in that it further comprises a receptacle (4) made of a thermoplastic polymer of spherolitic structure, placed inside the metal vessel (2) and intended to contain the waste. A device such as this ensures optimal containment while at the same time preserving a structural integrity and a mechanical strength over a period of at least one hundred years, this notably being the case in spite of the presence of chemically aggressive species. The invention also relates to a method of packaging nuclear waste using the device (1).

摘要： The invention relates to a transparent material which attenuates electromagnetic radiation and/or directly or indirectly ionising particles, of particular use for the production of transparent sheets which serve as protective screens for an operator against said electromagnetic radiation and/or particles. Said transparent attenuating material is made of a matrix of an organic glass in which at least one metal radiation-attenuating compound is dispersed (advantageously other than lead) in the form of nanoparticles, advantageously in the 'core-shell' form. The metals of the nanoparticle metal compounds form at least 25 % of the mass of the material.

摘要： A present invention provides polymer nanocomposites with dispersed nanotubes and methods of making same. The polymer may be a polyether. For example, the present invention provides an effective method to successfully disperse single walled nanotubes (SWNTs) into both polyethylenoxide (PEO) and its low molecular weight analog polyethylene glycol (PEG) with hydrodynamic percolation at about 0.09 wt % and an electrical percolation at about 0.03 wt % SWNTs, as shown in Figure 5, at room temperature, and the resulting nanocomposites. The method may include providing a surfactant. Most notably the present inventors achieved a decrease in the melting point of the polymer and a retardation of polymer crystallization due to the presence of the nanotubes.

摘要： The invention relates to a method for the containment of special waste. The special waste, preferably in the form of particles, is enclosed by a mixture which can be hardened and said mixture, enclosing the special waste, is subjected to a hardening treatment whereby a polymer concrete is formed. The mixture enclosing the special waste is enclosed in a container made of polymer concrete and said container can be produced by the same hardenable mixture. The hardenable mixture contains at least a) 10-50 wt. % of at least one hardenable resin, and b) 50-90 wt. % of at least one inert inorganic filling material in the form of particles, forming a base matrix. The components a) and b) are equal to 100 wt. %.
