Segmented lattice rack to store fuels coming from nuclear reactors

A segmented lattice rack for storing fuel components from nuclear power stations, having walls made of plates, the plates being orthogonally joined, forming a lattice defining numerous cell cavities, longitudinally coupled forming a sandwich, comprising:

• a) a central part of a material formed from neutronic poisons, coinciding with an active part of the stored fuel component, comprising:
• a plurality of intermediate units (4)-(8) which in one direction have successive parallel plates grooved on both sides, over which other grooved orthogonal plates are orthogonally installed and in both directions, which coincide with the center of the former and protrude above and below;
• where said lattices are coupled at a relative displacement of 90°,
• such that on one plane there is a discontinuity in height in one or other direction, but when piled, rotated with respect to each other, they couple forming conduits;
• and
• two end units (3) and (9), formed by parallel plates with a width equivalent to the difference between the two plates of the central units, arranged in a plane, so that they overlap the protruding part of the former, to finish the assembly on a same plane, closing the conduits;
• b) two end zones coinciding with a non-active part of the stored radioactive component, formed by two sets of lattices (1)(2) and (10)(11), the latter welded to a cover or end plate, providing rigidity to the rack.
