2D/1D Coupled Power Reconstruction Method for On-line Monitoring of PWRs

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.
