Abstract: A method for underwater packaging of radioactive materials includes creating a vacuum in a cavity of a cleaning device to automatically cause a portion of the cleaning device to move upward to actuate the cleaning device from an open position to a closed position; mounting the cleaning device inside a safe containment area of a transportation and/or storage device; placing the transportation and/or storage device in a pool after filling the safe containment area with water; loading a radioactive material into the safe containment area; closing the transportation and/or storage device using at least one cover; extracting the transportation and/or storage device from the pool; draining the water inside the safe containment area; and creating a pressure differential in the safe containment area to dry the safe containment area, wherein the pressure differential causes the cleaning device to automatically actuate from the closed position to the open position.

Abstract: Transport means surveillance system. It comprises: at least one camera (8) onboard the transport means (2); a means of detecting movement (31) in the surrounds of the transport means; an onboard server (14) that can hold images from the camera (8) and information from the means of detecting movement (31) close to the transport means; a telecommunication means (18, 20) to transmit data provided by the server (14) to a surveillance centre (46); a means (30) of detecting when the transport means stops, the server switching the camera on or off and activating or deactivating the means of detecting movement close to the transport means as a function of information that it receives from the means (30) of detecting when the transport means is stopped.

Abstract: The invention relates to a device (1) for cleaning and/or securing a safe containment defined in a device for transporting and/or storing radioactive materials, which device includes active means capable of cleaning and/or securing said safe containment, and further comprising means forming a casing (2) with an opening (8) and defining a cavity (9) as well as means for closing (10) said opening, which device is designed so that said closure means are capable of being maintained in said closed position by a pressure difference between the inside and the outside of said cavity.
