AbstractA segmented lattice rack to store fuels coming from nuclear reactors, whose walls are made of plates joined orthogonally forming a mesh defining multiple cell cavities which are longitudinally coupled forming a sandwich comprising a central part coinciding with the active part of the stored element, being from a material obtained from neutronic poisons, preferably boron treated steel; whilst the end areas coinciding with the non-active part of the stored radioactive element are of normal stainless steel, joined to each other and with the adjacent components by means of welding or pretensioning.
