Thermodynamics of the UO$$_{2}$$ solid solution with magnesium and europium oxides

Fujino, Takeo*; Sato, Nobuaki*; Yamada, Kota*; Nakama, Shohei*; Fukuda, Kosaku; Serizawa, Hiroyuki; Shiratori, Tetsuo*

Journal of Nuclear Materials, 297(3), p.332 - 340, 2001/09

 Times Cited Count:3 Percentile:27.65(Materials Science, Multidisciplinary)

Oxygen potential of solid solution Mg$$_{y}$$Eu$$_{z}$$U$$_{1-y-z}$$O$$_{2+x}$$ was examined as a function of O/Metal ratio at 1000, 1100 and 1200 $$^{o}$$C. The O/Metal ratio which gave the steepest change of the oxygen potential(GOM) was 1.995 for y=0.05, z=0.1 and y=0.05, z=0.05. The position decreased to 1.908 at higher Mg$$^{2+}$$ concentration of y=0.1, z=0.05. The GOM did not change with temperature in a range 1000-1200 $$^{o}$$C. At GOM, a friction of 0.473 of total Mg$$^{2+}$$ occupy the interstitial position of the fluorite lattice.
