Provide is a nuclear power station reactor core liquid level detector. The nuclear power station reactor level detector is characterized by comprising a pressure-bearing sleeve pipe, sheathed heating cables, sheathed thermocouples, nickel powder and Al2O3 powder, wherein the pressure-bearing sleeve pipe contains the sheathed thermocouples, N (N is larger than or equal to 2) heated sheathed thermocouples and sheathed heating cables which contain N (N is larger than or equal to 2) sections of resistive heaters, the sheathed thermocouples are located at the bottom of the pressure-bearing pipe, the axial length area of the N sections of the resistive heaters is filled with the tightly pressured nickel powder, the axial direction area beyond that is filled with the tightly pressed Al2O3 powder, and the sheathed thermocouples and the sheathed thermocouples at the heated places constitute a thermocouple measuring pair which measures the liquid level. The sensitivity of liquid level measuring is increased, and the ca
