Abstract

This work presents the Euler-Maclaurin method with a first-order delay low-pass filter for reducing fluctuations in reactivity calculation. A Gaussian noise around the mean value of the measured neutron population density. This noise is simulated with different standard deviations, with a fixed seed to generate random numbers to reproduce the results. Different numerical experiments show that the proposed method offers high accuracy and low computational cost when compared to different methods reported in literature, especially when compared to the finite difference method and the FIR filter method for different forms of neutron population density.
