摘要

The invention relates to a packaging for the transport and / or storage of radioactive materials, comprising a plurality of packaging elements (8) defining together a containment (4) of the radioactive materials, at least one of the elements of wherein the package is traversed by at least one fluid communication system (30) having, at an inner surface (40) of the enclosure, at least one fluid inlet opening (38a, 38b) and, at the a fluid outlet region (42) of the outer surface (44) of the packaging member, at least one fluid outlet opening (39), the system being associated with a closure cap (32) covering the fluid outlet area (42). According to the invention, the system (30) defines at least two distinct fluid flow paths (46a, 46b) between the fluid inlet opening (38a, 38b) and the fluid outlet opening (39). .
