For a better understanding of the Fukushima-Daiichi Nuclear Power Plant accident, a reaction model of core melting process is very important. In this study, oxidized Zry plates were soaked into molten SS-B$$_{4}$$C mixture and heated into Ar gas at 1200$$^{circ}$$C. Recession of ZrO$$_{2}$$ scale was observed in the both cases. An oxygen solid solution region in the Zry sample was observed below ZrO$$_{2}$$ scale, although it was not observed in Zry oxidized at 600$$^{circ}$$C in high temperature steam conditions. When oxygen supply from the surrounding was halted, ZrO$$_{2}$$ scale can be reduced at high temperature such as 1200$$^{circ}$$C by oxygen dissolution into Zry inside.
