Yukio Edano, the government's chief spokesman, said that it was possible the core reactor had been "deformed" by its exposure above water, but he denied that it was a meltdown.

在铸坯凝固末端轻压下直接作用区域，两相区受到压缩，枝晶间富含溶质的液相被挤出，相对于铸坯向液芯方向流动。轻压下之后，铸坯中心区域由糊状区内被压缩的固相及残留的液相构成，中心区域偏析指数下降。

The simulation results show that mushy region is compressed and interdendritic solute-rich liquid flows toward the liquid core in the soft reduction action zone at the solidification end of the slab.
