摘要
PROBLEM TO BE SOLVED: To provide a method by which the water level in an atomic reactor can be reliably measured even when the atomic reactor has lost electric power supply from outside, a power source for emergency source has also become unusable and further the sea water cooling function has been lost, and an apparatus for implementing the method.SOLUTION: A sealed cylindrical chamber 33 substantially the same in height and longitudinal length as an atomic reactor 1 is installed in advance; piping 19 branched in a T shape from an instrumentation tube 14 drawn from the atomic reactor 1 is connected to a lower part of the chamber 33; the upper part of the chamber 33 and the gas phase part of the atomic reactor 1 are linked by piping; the water level in the chamber 33 is kept the same all the time as that in the atomic reactor 1; a zigzag-shaped liquid level gauge 40 is installed in the chamber 33 in the lengthwise direction; a transparent tempered glass window is opened on a side face of the chamber 33 in a position opposite the liquid level gauge 40; and the water level in the atomic reactor 1 is measured by visual observation of the zigzag-shaped liquid level gauge 40 inside through the window of the chamber 33.SELECTED DRAWING: Figure 2
