A vessel electrical penetration assembly for a feed-through of nuclear reactor vessel, the assembly including: a docking tube to form an extension of the secondary containment barrier of the reactor, the docking tube including: a first end to be positioned in the interior of the vessel and to be mechanically and sealably connected to an actuator in the interior of the vessel, and a second end to be mechanically and sealably secured to the vessel; a seal-tight electrical bar that passes through the docking tube and having on either side seal-tight connectors ensuring an electrical link between the actuator and the exterior of the reactor; the seal-tight electrical bar including a system for limiting a leakage of primary liquid to the exterior of the vessel if the secondary containment barrier extension fails; and a mechanical maintaining system for securing, under the required pressure conditions, the electrical bar to the vessel.

The invention relates to a bag for sealingly packaging components, which includes: a flexible body (10) defining an inside space, including a communication opening and a side wall including a plurality of strips folded against one another; and a joining device which can selectively open or close the communication opening, and is shaped so as to be mounted on an enclosure to allow sealed communication between an inner cavity of the enclosure and the inside space of the bag, the bag being characterized in that at least one fold made up of two strips opposite one another is detachably connected to at least one other fold.

1. Method and device for connecting a protective cover to a safety cover sealed against the environment.

2. The invention relates to a method and an assigned device for connecting a first at least partially flexible protective cover (2) sealed against the environment, which cover forms a barrier between a contaminated (12) and an uncontaminated area, to a second at least partially flexible safety cover (20) including the process stages listed below: Transferring the protective cover (2) out of the contaminated area (12) by inverting the protective cover (2) over an opening such that its inside is turned out and then severing it from the safety cover (20) and closing the opening; or transferring the protective cover (2) from the contaminated area (12) by sheathing the protective cover (2) with the safety cover (20) as it is pulled through a passage and subsequent severing of both covers (2, 20) from the safety cover (20) and closing the sheathing; or pulling the protective cover (2) back into the contaminated area (12) and then sealing the ends shut to sever the safety cover(20) by forming a further sealed joint between adjacent film parts.

The invention relates to a containment enclosure comprising two compartments (21, 22) and a sealing system between the two compartments. The sealing system (16; 23, 30) comprises a door (23) having two opposite faces (23a, 23b). The door comprises a transfer support (30) on one of its faces. According to the invention, the door allows two closed positions distinct from one another, in which positions the door forms a gastight interface between the two compartments.

A device for preparing radioactive solutions, in particular radiopharmaceutical solutions, including: a movable support block with at least two cells capable of accommodating a vial; and a shielded covering, including a side wall surrounding the periphery of the support block and an upper wall covering the upper face of the support block, an opening being provided in the upper wall of the covering. A means for driving the support block is configured to selectively displace the support block into positions, referred to as working positions, in which a given cell is aligned with the opening to allow access to the cell from the outside of the covering. The support block is configured such that it can be further brought to a position, referred to as closing position, in which the opening is sealed by a shielded element carried by the support block.

A method is described for providing selective communication between two enclosures. The first enclosure includes a first flange and a first door. The second enclosure includes a second flange and a second door. The method includes performing sequentially the steps of arranging the second flange on the first flange, axially maintaining the second flange on the first flange by snap-fitting, securing the first flange to the second flange, securing the first door to the second door, releasing the first door from the first flange, releasing the second door from the second flange, opening the first door relative to the first flange, closing the first door relative to the first flange, securing the first door to the first flange and securing the second door to the second flange, unlocking the first door from the second door, and separating the first door from the second door.
