Abstract: The invention relates to a process for treating alkali metals such as sodium charged with tritium or components contaminated with alkali metals such as sodium charged with tritium, in which the alkali metal is reacted with liquid water or water vapor, so as to obtain hydrogen and tritiated hydrogen, characterized in that the hydrogen and the tritiated hydrogen are subjected, in a recombiner (2) to a treatment of catalytic recombination by the addition of oxygen so as to obtain water and tritiated water, and in that the water and the tritiated water are treated so that they are not discharged into the environment. The invention also relates to a plant for carrying out the process.

Abstract: A transverse axis tubular hub (24) couples each propulsion unit (4) to the vehicle body (2), and supplies signals representative of the forces that it transmits. A tilt motor (22) of the propulsion unit bears on the hub to tilt the propulsion units about a transverse axis, on which a drive motor is disposed.

Abstract: A transverse axis tubular hub (24) couples each elongate propulsion unit (4) to the vehicle body (2). It supplies signals representative of the forces that it transmits. A tilt motor (22) of said propulsion unit bears on said hub to tilt said propulsion units about said transverse axis. In accordance with the invention a drive motor is disposed on said axis.The invention is particularly applicable to working in environments harmful to man.

Abstract: The invention concerns a vehicle (1) with inclinable tracks in which an inclination movement of a propulsion unit (3) about its articulation axis (5) is assisted by reverse propulsion movement of the track (4) of the propulsion unit.The invention is applicable to the nuclear industry in particular.

Abstract: An intervention vehicle of the type comprising propulsion units (4) that are tiltable by rotation about transverse carrying shafts (66), comprising advance and tilting driven shafts (8, 9) disposed coaxially inside each carrying shaft (66) and transmitting their motion via linear transmission elements (84, 90, 98) inside each propulsion unit for driving advance motion and tilting motion, and also constituting a speed reducer for the tilting motion. The invention is particularly applicable to the nuclear industry.

Abstract: A vehicle for interventions, in particular in buildings, characterized by the fact that it includes a scissor-like chain transmission (22, 40-24, 42) for transmitting the motion required between motors (10, 12) carried by the body of the vehicle (2) and propulsion units (4) having limited mobility relative to the body. The invention is particularly intended for the nuclear industry.
