Abstract

Improvements in structures of lockers for housing fuel elements of nuclear reactors, characterized in that each structure is constituted by a plurality of identical modules or lockers, prismatically, inside each of which are housed vertically one or several bundles of fuel elements not integral with the locker, the walls of the lockers being provided with control means for control rods, with means for supplying emergency coolant and with means for positioning in the position of measuring devices.
