Development of hydrogen concentration monitors based on the application of ultrasonic technology applicable to severe accidents in nuclear reactor facilities was conducted. This paper introduces the principle and features of the application of ultrasonic technology. This paper introduces the principles and features of the ultrasonic application, and describes the performance (measurement accuracy, time response, etc.) and environmental resistance of the prototype as development results. In addition, the application of the developed technology would be introduced.
