System for the transfer and storage of radioactive waste for a shielded cell

A system for the transfer and storing of radioactive waste for a shielded cell comprising a work surface (2) having an discharge duct (3) for allowing discharge of the radioactive waste, the system (1) comprising:

• a first frame (4), which is attachable to the shielded cell below the work surface (2);
• a shielded container (8), which is suitable for containing the radioactive waste, extends along a first axis (9) and is provided with a collar (20);
• a rapid transfer port, which comprises an alpha port (18) fixable to the discharge duct (3) and openable from inside the shielded cell, and a beta port (19) that closes the shielded container (8);
• a second frame (10), which supports the shielded container (8) through the collar (20) and is movable with respect to the first frame (4) along a direction (6) transversal to the first axis (9) to and from an alignment position, wherein the shielded container (8) is coaxial to the discharge duct (3);
• a shielded cover (21), which is mounted on the collar (20) in a movable manner between a first position, in which the shielded cover (21) covers the beta port (19), and a second position, in which the shielded cover (21) is out of the way to allow the shielded container (8) to be lifted from the collar (20);
• a shielded shutter (42), which is mounted below the work surface (2) in a movable manner between a third position, in which the shielded shutter (42) covers the discharge duct (3), and a fourth position, in which the shielded shutter (42) is out of the way in relation to the discharge duct (3);
• a lifter (49) for moving the shielded container (8) parallel to the first axis (9) to and from a raised position, in which the beta port (19) rests against the alpha port (18) and which is reachable when the second frame (10) is in the alignment position, the shielded cover (21) is in the second position and the shielded shutter (42) is in the fourth position;
• and a rotating key (52), which is mounted on the first frame (4) to rotate coaxially to the discharge duct (3) and is engageable by an outer portion (32) of the shielded container (8) when the latter is in the raised position, to allow, by rotation of a predetermined angle, coupling between beta port (19) and alpha port (18) and opening of the rapid transfer port.
