Method for measuring height of waste in nuclear waste tank

The invention relates to the field of nuclear waste treatment, in particular to a method for measuring the height of waste in a nuclear waste tank. The method for measuring the height of the waste in the nuclear waste tank comprises the steps that a transmitting device is installed at a first preset position of a tank body, and a receiving device is installed at a second preset position of the tank body; measuring out-of-tank height data of the transmitting device; the height signal representing the height of the waste material and output by the receiving device is received, and the height of the waste material is determined by combining the height data outside the tank; wherein the first preset position is lower than the second preset position. Therefore, according to the method for measuring the height of the waste materials in the nuclear waste tank, through the arrangement of the transmitting device and the receiving device, the height of the nuclear waste materials in the nuclear waste tank can be accura
