Estimation of Internal Pipe Wall Temperature under Operating Conditions in Pipe Circuits using Ultrasound

There is concern that rapid temperature changes in the primary cooling circuit of reactors can induce thermal fatigue that can be detrimental to the overall life of components in the primary circuit. It is therefore desirable to monitor the number and magnitude of cross wall temperature changes in these components so that one can better estimate the magnitude and number of stress cycles that a component experience to predict the overall life of the components. This project aims to build on the outcomes of a recent feasibility study to enable real-time monitoring of temperature wall gradients in primary circuit components under realistic conditions (up to 350 degrees C).
