To some extent, rare-earth-doped UO(2) is representative of an irradiated nuclear fuel. The two phases we observed previously in neodymium-doped UO(2) are now interpreted as the existence of a miscibility gap in the U-Nd-O phase diagram using new results obtained with Raman spectroscopy. Extrapolating the miscibility gap in the U-Nd-O phase diagram to irradiated UO(2) opens the path to a new understanding of nuclear oxides in the environment.
在某种程度上，掺稀土的 UO(2)是辐照核燃料的代表。我们之前在钕掺杂 UO(2)中观察到的两个相，现在根据拉曼光谱获得的新结果，被解释为 U-Nd-O 相图中存在混溶性间隙。将 U-Nd-O 相图中的混溶性间隙外推到辐照 UO(2)，为理解环境中的核氧化物开辟了新的途径。
