机译：Comparisons of the different approximations leading to mesh centered finite differences starting from the analytic nodal method
ew review the derivation of the Analytic Nodal Method and applythe different approximations such as zero transverse leakage and thetrunca- tion of the matrix exponentials to obtain the mesh centeredfinite difference approximation. The effect of each of theseapproximations are then compared to a reference solution obtainedwith the Analytic Nodal Method and a quadratic transverse leakageterm. A model of a CANDU-6 reactor with in- core reactivity devices(21 adjuster rods and 14 zone controllers) is used to compare theeffect of all these approximation steps.
