Abstract
A storage basket for radioactive materials, defining housings parallel to each other and each extending along a housing axis parallel to a longitudinal central axis of the basket, the latter including: a plurality of transverse plates, traversed by a plurality of openings; a plurality of housing tubes arranged parallel to the longitudinal central axis of the basket. The housing tubes are arranged in alternation with the transverse plates along the axis, such that the inner lateral surface of each housing is defined, successively along this axis, at least by the inner surface of a first housing tube, the inner surface of one of the openings of a first transverse plate, and the inner surface of a second housing tube.
Claims14
A storage basket (1) for radioactive materials (2), the basket being to be arranged into a containment enclosure (12) of a packaging (100) for transporting and/or warehousing radioactive materials, the basket defining a plurality of housings (4) each for receiving radioactive materials (2), the housings being parallel to each other and each extending along a housing axis (8) parallel to a longitudinal central axis (6) of the basket, the latter including:
- a transverse plate or a plurality of transverse plates (20) distributed along the longitudinal central axis (6) of the basket and arranged orthogonally to this axis, each plate (20) having a plurality of holes (24) passing therethrough;
- a plurality of housing tubes (26) arranged parallel to the longitudinal central axis (6) of the basket,
- wherein the housing tubes (26) are arranged alternately with the transverse plate(s) (20) along the longitudinal central axis (6), so that the inner side surface (4a) of each housing (4) is defined, successively along this axis (6), at least by the inner surface of a first housing tube (26), the inner surface of one of the holes (24) of a first transverse plate (20), and the inner surface of a second housing tube (26).
