概要
The water level in the nuclear reactor measures it by measuring the differential pressure of a vapor phase part and the liquid phase part in the nuclear reactor. However, the temperature in the storage container becomes the high temperature at the time of the SA such as the Fukushima accident, and the water in the datum level device evaporates, and nuclear reactor water level becomes immeasurable. We developed a technique to measure the water level in the direct furnace by applying TDR (time-domain reflectometer ) technique of GE Hitachi for the purpose of evading such a situation, and measuring the reflection time of the pulse jointly and planned the diversification of the hydrograph.
