Abstract

Method for detecting entrainment of a gas in a coolant in a nuclear reactor, including the steps of generating an ultrasonic signal, propagating the ultrasonic signal through the coolant along a passage in the nuclear reactor, receiving the propagated signal, separate the higher order harmonics from the fundamental frequency of the received signal, and monitor the changes in the higher order ammonics to measure the initiation of gas entrainment.
