Abstract

A control technique for O/M ratio was established for measurements of high temperature properties of uranium and plutonium mixed oxide fuels. Sintering behavior, thermal expansion and O/M change of (U_0.7Pu _0.3)O_2.00 and (U_0.7Pu_0.3)O _1.99 were investigated in P0₂-controlled atmosphere which was controlled by H₂/H₂O gas system. Sintering behavior changed drastically with O/M ratio, and shrinkage of (U_0.7Pu _0.3)O_2.00 was faster and more advanced at lower temperatures as compared with (U_0.7Pu_0.3)O_1.99. Thermal expansion was observed to be slightly increased with decreasing O/M ratio.
