Incoming and outgoing air conveyance for dry storage with self heating radioactive materials

There is described an incoming and outgoing air conveyance system for dry storage with self heating radioactive materials in which the incoming air openings and shafts and the outgoing air openings and shafts guarantee a favorable flow of the cooling air and guarantee an undisturbed cooling even with external disturbances. This is obtained by: (A) arranging the incoming openings in each case both above and laterally on one or more incoming air shafts and providing them with deflection projections or deflection edges, placing deflection plates between the incoming air openings lying above and the lateral incoming air openings and furnishing the lateral incoming air openings with wall projections, (B) leading the incoming and outgoing air shafts without substantial curvature up to the stored material and (C) providing the outgoing air openings carried upwardly with chimney tops having drop edges and deflection plates and wherein there are arranged protective sills between the outgoing air shafts and deflection plates
