This patent describes a method of measuring the level of a corrosive, high-pressure, high-temperature liquid in a closed container of a nuclear reactor. It comprises: providing a generally tubular structure connected to the closed container of the nuclear reactor so that the level of liquid in the tubular structure is indicative of the level of liquid in the closed container, providing a sealed buoyant float sized to move vertically up and down within the tubular structure, detecting from outside the tubular structure the vertical position of the buoyant float.
