Abstract
The outer surface of a cladding tube of a nuclear fuel element is -- for the purpose of improving the heat exchange between the cladding tube and a surrounding coolant -- provided with a plurality of parallel fin rows extending normal to the cladding tube axis. Each row is constituted by a plurality of spaced, individual fins; the fins of any one row are offset with respect to the fins of an immediately adjacent row.
Claims3
A nuclear fuel element cladding tube having a longitudinal axis and an outer surface, comprising a plurality of fins carried on said surface, said fins being arranged in a plurality of parallel-spaced rows extending at right angles to said axis, the fins in any one of said rows being spaced from one another and being offset relative to the fins of an immediately adjacent row, the distance between immediately adjacent rows being twice the height of the individual fins and the distance between two adjacent fins in alignment parallel to said axis being four times said height.
