The Nuclear Safety Department of the French Commissariat a l'Energie Atomique has achieved an important experimental program relating to the criticality of 4.75-wt%-235^U-enriched UO₂ rods in water with various configurations. Two series of recent results are presented first series, completing the parametric study, deals with square-pitch lattices immersed in a sodium nitrate solution (H₂O+NaNO₃), and the second series deals with four assemblies of 1818 rods, between which various hydrogen compounds have been interposed.
