摘要

Improvements in nuclear reactors, and especially referred to devices for introducing objects in a sealed enclosure, and removal of these objects to the outside of said enclosure, device usable especially in a refueling installation of nuclear reactor fuel elements, to introduce containers with combustible elements in a barn that constitutes said enclosure, and remove them from it, characterized by comprising first mobile means in a first tunnel that carry out the transfer of the objects between the collection department and another point in communication with the outside of the enclosure; first sealing elements disposed between the first means and the first tunnel for separating the collection department from the room when the first means occupy a position for which the objects are in said department, and second sealing elements arranged between the second means and the second means; second tunnel, to separate the collection department from the outside, when the second media occupies a position for which the objects occupy the other point.
