METHOD OF CONTROLLING PRESSURE IN A FUEL ROD
A method and a system includes controlling and monitoring the gas pressure in a nuclear fuel rod during filling of the fuel rod with a gas, and subsequent sealing of the fuel rod. The system includes a control unit and a length measuring system, which control unit is communicatively connected to the length measuring system. The length measuring system is configured to monitor the length of the fuel rod, and the control unit is configured to receive measurements from the length measuring system and to determine the gas pressure inside the fuel rod on the basis of variations of the length of the fuel rod. The method includes positioning an open first end of the fuel rod inside a pressure chamber, allowing gas to enter the fuel rod; pressurizing the gas in the pressure chamber at a first pressure level; closing the fuel rod; and sealing the fuel rod.
BIDIRECTIONAL DEVICE FOR CHANGING A HANDLING GLOVE AND METHOD FOR REPLACING SAID GLOVE BY TRANSLATION
The invention relates to a bidirectional device for changing a handling glove from the inside towards the outside and from the outside towards the inside of a glove box under containment. The device is intended for replacing a used glove (60) with a new glove. The device comprises a cuff (6) sealingly connected to a cuff sleeve (20) and a glove (60) made of a flexible material sealingly connected to a glove sleeve (40). The glove sleeve comprises snap-fitting studs on the outside and the cuff sleeve comprises axial ramps (30). The snap-fitting studs of the glove sleeve slide in the axial ramps of the cuff sleeve until the glove sleeve is locked, forming, once assembled, a sealed assembly referred to as cuff port (10).
Method for transporting material in and out of atmosphere-containment structures
The invention provides a system for preventing fluid exchange between the interior and exterior of containment enclosures such as process-, hazard-, and research-enclosure systems generally, gloveboxes, containment systems, isolation systems, confinement systems, cleanrooms, negative air systems, and positive air system areas while simultaneously providing material transfer into and out of the enclosures. The invention also provides a method for transporting material into or out of a containment structure.
RESOURCE LOADING SYSTEM AND METHOD FOR USE IN ATMOSPHERE CONTAINMENT SCENARIOS
The invention provides a system for preventing fluid exchange between the interior and exterior of containment enclosures such as process-, hazard-, and research-enclosure systems generally, gloveboxes, containment systems, isolation systems, confinement systems, cleanrooms, negative air systems, and positive air system areas while simultaneously providing material transfer into and out of the enclosures. The invention also provides a method for transporting material into or out of a containment structure.
DOOR ARRANGEMENT FITTED TO A FIRST ENCLOSED SPACE FOR REDUCING CONTAMINATION RISKS WHEN A SECOND ENCLOSED SPACE IS CONNECTED TO THE FIRST ENCLOSED SPACE
The invention relates to a door arrangement (1) for a first enclosed space enabling a sealed connection between the first enclosed space and a second enclosed space, comprising a flange (2) defining an opening into the first enclosed space, a door (4) hingedly mounted on the flange (2), means for securing the flange of the second space pressed against the flange of the first space, the means comprising locking catches (8) which are movable between an unlocked position in which they are recessed inside the flange (2) and a locked position in which they project radially from the flange (2) to the opening, thereby locking the flange of the second space without rotating the flange (2) by engaging each catch in a notch provided on the outer peripheral edge of the flange of the second space.
Device for the sealed transfer between two enclosed volumes, comprising an external control lever
The invention relates to a device for sealed transfer between two enclosed volumes, comprising a first flange and a second flange (10) which define a passage opening into the enclosed volumes and can be secured to each other by a first bayonet connection, a first door and a second door (11) which close off the passage openings and can be secured to each other by a second bayonet connection, the first door (11) being hingedly mounted on the first flange (10) by means of a hinge (4) comprising a hinge pin, characterized in that the device comprises an external manual control lever (9) which is secured to a rotary pin penetrating the first flange (10) and which is coupled to the hinge pin in such a way that the actuation of the control lever (9) drives the hinge pin, thus opening or closing the first door (11).
