The reconstruction method of assembly flux fine distribution for finite-difference method
Description
In order to accurately model the response of neutron detectors, it is necessary to reconstruct the assembly flux fine distribution from the flux distribution calculated by the finite-difference method, with the two-dimensional bi-quadratic spline function as the most ideal and convenient tool. The detailed procedure and formulas are given. This method can be applied to problems with any flux distribution shape and any difference meshes pattern, and can ensure the neutron current continuity in the assembly edge
