| 英文摘要 | U3Si2 has been regarded as a promising candidate for the accident tolerant fuel (ATF) in light water reactors (LWRs). To improve the performance of U3Si2, metal M (M=Al, Ti, V, Zr, Nb and Mo) as additions is of great interest. Here we studied the phase diagrams of the U-Si-M systems using the CALPHAD (CALculation of PHAse Diagram) approach aided by the first-principles calculations, to explore the M solubility in U3Si2. The results show that the M solubility is closely related to the electronegativity, the atomic size and the number of mesophases. To be specific, the solubility of M increases with the decreased differences in radius and electronegativity between Si and M, as well as the reduced number of intermediate phases in the binary U-M and Si-M systems. In addition, Al has the largest solubility in U3Si2 among all the elements studied, whereas Zr and Ti have minute solubilities. These findings may facilitate the exploration and development of novel ATF materials. (C) 2021 Elsevier B.V. All rights reserved. |
