However, there is a possibility that air may remain in the instrumentation pipe 3a as shown in FIG. 3 as shown in FIG. 3, so that water is further supplied to the hand pump 13 shown in FIG.
Alternatively, water is pushed in by the electric pump 14.

The greater the amount of water to be blown, the higher the reliability of water filling. However, usually, the capacity is about 10 times the capacity of the instrumentation pipe 3a. In addition,

Then, the water filled water in the instrumentation pipe 3a drops the dissolved air equivalent water column 26 that has escaped. This phenomenon appears remarkably in the instrumentation pipe 3a connected to the reference container 4.

運転の際の原子炉水位変動は広く知られている。As a result, the pressure applied to the low pressure side of the differential pressure gauge 2 decreases and the pressure difference between the high pressure side and the high pressure side decreases, so that the reactor water level appears to rise, and an alarm or an interlock may malfunction. . The fluctuation of the reactor water level during the deaeration operation at the time of starting the reactor is widely known.

Then, the temperature of the water in the instrumentation pipes 3, 3a must be raised and degassed.
