Abstract: A conveyor device has a sequence of two vibrating screens vertically separated (d) from each other and supplying an alignment bowl, to eliminate chips and residue from nuclear fuel pellets stored in bulk in a boat and to align them in order to fill fuel rods. Due to these two screens, pellets are set aside and turned over, and chips are efficiently separated in a pot, without any congestion of the system.

Abstract: Process for decontaminating, cleaning a solid organic substrate contaminated by solid radioactive particulate inorganic contaminants, in which: the said solid substrate is brought into contact with an extraction medium, devoid of water, comprising: dense pressurized CO2; at least one nonhalogenated surface-active compound chosen from block copolymers of poly(ethylene oxide) PEO and poly(propylene oxide) PPO, such as (EO)x-(PO)y diblock copolymers, (EO)x-(PO)y-(EO)x triblock copolymers and (PO)x-(EO)y-(PO)x, triblock copolymers, where x and y are integers from 2 to 80 with x other than y; and polydi(1 to 6C)alkylsiloxanes, such as polydimethylsiloxane (PDMS); and at least one complexing agent chosen from tributyl phosphate (TBP), crown ethers, tributylphosphine oxide, triphenylphosphine oxide and tri(n-octyl)phosphine oxide; the solid substrate and/or the extraction medium is/are subjected, simultaneously with the contacting operation, to a mechanical action.

Abstract: The invention concerns a glove having high mechanical performance, and high resistance to chemical products and/or radiolysis, characterised in that it comprises one or several elastomer layers, identical or different, obtained from solutions of said elastomers in one or several organic solvents or in water, said layers being reinforced, on one or several parts or on the entire internal surface of the glove, with a fabric with high mechanical strength. The invention also concerns a method for making said glove and its uses.
