Nuclear leakage protection wall and applications thereof

The invention discloses a nuclear leakage protection wall and applications thereof, wherein the wall comprises a sacrifice layer and a protection layer wrapped on an outer surface of the sacrifice layer, the sacrifice layer is made of a ferrosilicon sacrifice concrete material, and the protection layer is made of an ultra-high performance concrete material. According to the present invention, thenuclear leakage protection wall can effectively resist the vapor pressure of the non-condensable gas generated by the reaction between reactor core melt and reactor pit area ferrosilicon sacrifice concrete and the generated instantaneous thermal load on the support structure around the reactor pit area; by using hematite ore as aggregate, ultra-high performance concrete can be used as the second protection barrier to prevent reactor core melt leakage caused by the insufficient thickness of the ferrosilicon sacrifice concrete; and with the application of the nuclear leakage protection wall, thestructure of a reactor co
