| Abstract Scope |
Thermal conductivity of the ternary compound (U2Cr)N3 was measured experimentally by the Transient Hot Bridge technique and compared with the results predicted using modeling calculations. The ternary phase (U2Cr)N3 was obtained experimentally for the first time in the composite pellets by combining UN powders and CrN powders and sintering using SPS (Spark Plasma Sintering) method. The crystal structure of the ternary U2CrN3 phase was investigated and the positions of the Cr atoms were obtained. The elastic properties of the (U2Cr)N3 phase were also obtained by modeling calculations. The uranium density of the ternary compound (U2Cr)N3 is higher than that of UO2 making it a promising candidate for the Accident Tolerant Fuel (ATF) concept. |
