ABSTRACT:
A cooling fin for a spent nuclear fuel storage cask is fabricated by bending an elongated composite sheet, formed by cladding a stainless steel sheet onto a carbon steel sheet, along its axis to provide two sides joined at a curved apex. The free ends of the sides are welded to the base element of the cask. A pocket is formed between the sides of the fin by welding an end plate to the bottom of the fin, and thereafter resinous neutron absorbing material is poured into the pocket. After the pocket is filled an end plate is welded to the top of the fin.
