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).

人们担心，反应堆的主冷却回路中的快速温度变化可能引起热疲劳，这可能对主回路中的部件的整体寿命有害。因此，期望监测这些部件中的横壁温度变化的数量和幅度，使得可以更好地估计部件经历的应力循环的幅度和数量，以预测部件的总体寿命。该项目旨在建立在最近的可行性研究的结果基础上，以实现在现实条件下（高达350摄氏度）实时监测一次回路组件中的温度壁梯度。
