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

人们担心，反应堆一次冷却回路的快速温度变化可能导致热疲劳，这可能对一次回路中部件的整体寿命有害。因此，需要监测这些部件中横壁温度变化的数量和幅度，以便能够更好地估计部件经历的应力循环的大小和数量，以预测部件的整体寿命。该项目旨在以最近可行性研究的结果为基础，在实际条件下（高达350摄氏度）实时监测初级电路组件的温度壁梯度。

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).
