| 摘 要： | 针对三代核电压水堆在线监测系统需要快速准确进行实测3D功率重构的需求，本文提出了一种2D/1D耦合的3D功率重构方法。首先采用耦合系数法对探测器层的功率进行了2D实测功率重构；其次针对每个组件，采用二次样条函数拟合方法进行了轴向1D实测功率重构，最后得到了全堆3D实测功率分布。该方法计算流程简单，占用内存少。针对华龙一号开展的4个典型例题的数值验证结果表明，该方法具备很高的精度，满足三代核电在线监测系统实测功率重构对精度和速度的要求。

| Abstract: | In this article, a 2D/1D coupled power reconstruction method for on-line monitoring purpose was presented. The coupled coefficient method was used to reconstruct the radial power distribution, and the second-order spline curve fitting method was used to reconstruct the axial power distribution of each assembly. The proposed method is simple, easy-to-implement and of low computational cost. Various comparative experiments based on Hualong One show that the proposed method is of low computational cost and provides high reconstruction accuracy. |
