STORING RACK FOR NUCLEAR FUEL ELEMENT ASSEMBLIES

摘要

Storage rack for assemblages of nuclear fuel elements of polygonal or circular cross-section comprised of a plurality of storage chambers in the form of a hollow stem having a cross-section adapted to that of the assemblages to be stored, said storage chambers being side by side in a regular disposition and each separated from the other by a regular spacing, each chamber being comprised of one or more rectangular metal plates formed by bending or melted metal sealing into a hollow stem having walls disposed to form a prismatic or cylindrical surface and adapted to contain said assemblages and being supplied at the bottom with a base capable of supporting said assemblage, wherein the metal plates forming said chamber protrude outwardly from said prismatic or cylindrical surface on at least two locations of the chamber contour, forming at these locations projections on which adjacent chambers are applied and attached, the assembly of chambers being without cross-pieces or coupling or packing pieces, and forming a self-supporting structure capable of being inserted into a proper storage room for assemblages of nuclear fuel elements.
