摘要： The device is applicable to the connection of two enclosures, each having a door closing and opening formed in a flange. One of the doors supports a rotary control member having three series of slots forming cams. V-shaped levers articulated to the doors simultaneously cooperate with slots and with the bolts in order to displace the latter between locking and unlocking positions under the action of rotating the member. The configuration of the slots makes it possible to control the locking of the doors to one another and to the flanges in a sequential manner. Preferably, the bolts are inclined in the direction aiding sealing.

摘要： The invention concerns the recovery of Pu (IV) by using crown compounds.According to the invention, the aqueous solution containing the plutonium (IV) is placed in contact with at least one crown compound, for example DCH 18C6, dissolved in an organic diluting agent, such as benzonitrile. In the case where the solution only contains traces of Pu, it is possible to use a crown compound secured to a solid phase, such as silica.The aqueous solution is a concentrated solution of fission products, an effluent originating from an irradiated nuclear fuel reprocessing installation or a concentrated solution of plutonium with americium.

摘要： For passing stepwise bottles (F, F') in front of different stations, in order to more particularly take liquid samples, the bottles are placed in receptacles formed on a plate (24). The rotation of the plate is ensured by a lifting support action using compressed air delivered by injectors (18). Immediate rotation stoppage is obtained when a hole (38) formed in plate (24) faces the end of an optical fiber, whereof the opposite end issues onto an optical detector. Associated with an automatic sampling and dilution system, the assembly can be advantageously installed in a glove box or shielded enclosure in the nuclear industry.

摘要： Apparatus for measuring the .alpha. activity of a solution and used for determining the plutonium concentration of a solution sampled from an irradiated nuclear fuel reprocessing installation and which comprises a rotary drum (20), which samples a film of solution in a vessel (20), in order to place it in front of a measuring probe (22). Between the probe (22) and the drum (20) is positioned a sealing disk (40) having three positions, which has an effective measuring region (48), a measuring chain quality checking region and a blank measuring region. In order to avoid a solution deposit by condensation on the disk (40) or on the end of the probe (22), a protective gas injection system (49) having passages traversing the vessel cover (16), scavenges the upper face of the sealing disk at three locations corresponding to the three active regions of the latter. A substantially uniform distribution of the gas flow between said three locations is ensured. The protective gas is then sucked in by a tube (122).

摘要： During the dismantling of a nuclear reactor fuel assembly, there is a simultaneous gripping of all the rods (a) arranged in square grid form in said assembly using a device (10) which effects a clamping or locking at the end of the rows of rods. For this purpose, device (10) has passageways (26) penetrated by the ends of two adjacent rows of rods (a). In said passage ways are trapped mobile members (34, 34') arranged in such a way that each rod is placed between two adjacent members. By applying a locking force on the mobile end members in each passageway (26), each rod is gripped between two members (34, 34'). Preferably, the mobile members (34, 34') are provided with abutments limiting the locking or clamping force individually applied to each rod. For filling the gaps of the grid of rods (a) corresponding to the locations occupied by the guide tubes in the assemblies, rollers (78) are placed in the passageways (26) at the corresponding locations.
