Two systems, namely UO $_{2}$ -Zr-Fe $_{3}$ O $_{4}$ and UO $_{2}$ -Zr-steel were studied at temperatures of 2000-2100 $^{circ}$ C, in comparison with the reference UO $_{2}$ -Zircaloy (Zry) system. All tests were performed in an argon atmosphere at a UO $_{2}$ /Zr mole ratio varied from 16 to 18. Under the given test conditions, the addition of iron to the UO $_{2}$ -Zry system results in a lower content of U in the resulting melt, regardless of the initial chemical form of iron. The resulting phases obtained in all three tests were compared with the composition of actual fuel debris samples collected at the sites of severe nuclear accidents.
