Abstract
Sealing device (10) between two media and the outer surface of a fuel cladding (1), characterized by three states: a state retracted for contactiess axial insertion of said fuel cladding (1) though the sealing device, a state statically hermetically sealed around said fuel cladding maintained at rest, and a state dynamically hermetically sealed around said fuel cladding under axial and/or rotational movement.

1-4. (canceled)
Sealing device (10) intended for providing a sealing between an aperture of an enclosure (7) and the outer surface of a nuclear fuel rod cladding (1) inserted through said aperture, wherein said sealing device comprises a retractable and inflatable member having three states:
- a state retracted for contactless insertion of said nuclear fuel rod cladding (1) through the aperture,
- a state inflated at a moderate pressure for providing said sealing while enabling axial and/or rotational movement of said nuclear fuel rod cladding, and
- a state inflated at a higher pressure for providing said sealing while said nuclear fuel rod cladding is at rest.
