法国核电厂蒸汽发生器的管支撑板堵塞的无损检测方法是目前常用的方法。一个随机的方法已被应用到有限元电磁场模拟，以评估材料属性的不确定性对监测信号的影响。多项式混沌展开方法使得可以容易地导出Sobol分解，该分解测量每个输入参数的可变性对模型输出的影响程度。
A nondestructive testing procedure is currently used to estimate the clogging of tube support plates in French nuclear powerplant steam generators. A stochastic approach has been applied to the finite-element electromagnetic field simulation to evaluate the impact of material properties uncertainties on the monitoring signal. The polynomial chaos expansion method makes it possible to easily derive the Sobol decomposition which measures how much the variability of each input parameter affects the model output.
