“…These elements can form intermetallic compounds (IMCs) with U [2,3] and Pu. The thermodynamic stability of these compounds is close to that of nitrides UN and (U,Pu)N [4]. This means that IMCs of U and Pu with noble metals Ru-Pd are the most probable chemical state of actinides in spent nitride fuel.…”

The intermetallic compound (IMC) PuPd 3 was synthesized by induction fusion of the components in a vacuum. The phase composition of the compound was confirmed by X-ray diffraction analysis. SEM analysis revealed the presence in the sample obtained of three metastable PuPd x phases (2.3 < x < 4.4) differing in the extent of enrichment in Pu. Data on the electrochemical properties of PuPd 3 in the 3LiCl-2KCl salt eutectic were obtained for the first time. Three main peaks of anodic oxidation are observed in the cyclic voltammogram of PuPd 3 at potentials of -1.74, -1.24, and -0.09 V (vs. Ag/AgCl). At potentials exceeding +0.6 V (vs. Ag/AgCl), PuPd 3 passes into the transpassive state. At lower potentials, anodic oxidation of IMC leads to the Pu dissolution in the form of Pu(III), but the simultaneously oxidized Pd is reduced on the electrode, which results in the enrichment of its surface in Pd.

“…However, these transition metals may also react with UN. The early work by Fee & Johnson (1975) [109] suggests the possible formation of U(Pd,Rh,Ru)3. Uno et al (1997) [110] investigated reactions of uranium nitride with platinum-family metals.…”
