Derivation and Preliminary Verification of Algorithm for Homogenized Flux Reconstruction

The algorithm of homogenized flux reconstruction based on the plane wave expansion method is derived and programmed in the 2D（Two-dimensional） polar coordinate system. The general solution form suitable for the discrete calculation could be given by using the base expansion functions of plane wave in the diffusion equation. The preliminary programming and verification results show that the algorithm and its program implementation can achieve reasonable accuracy in the 2D lattice level.
