ABSTRACT:
A radiation-tight coupling arrangement for coupling a machining laser to a hot cell containing radioactive material, comprising a cell flange integrally formed on the confinement wall which defines a cell opening, a cell door formed to interlock tightly with the cell flange, thereby closing the cell opening, an elongated container movably arranged in the sleeve and having a container flange defining a container opening and connected by a sealing bellows, a container door formed to interlock tightly with the container flange and to interlock with the cell door when the container flange interlocks with the cell flange, and a machining line translationally arranged in the container. When the container is in a retracted position, a radiation blocking drum intervenes between the cell opening and the container opening. The radiation blocking drum is rotated to allow the container to translate toward the cell. As a result of rotation of the container, the container flange interlocks with the cell flange and the container door interlocks with the cell door. The container door and cell door are then removed in tandem, allowing the machine head of the machining line to be inserted into the hot cell. The laser beam passes through the machine head and impinges on the radioactive material to be cut.
