Abstract

A different way to reduce fluctuations in the reactivity calculation using the exponential filter and the inverse point kinetics equation is shown. The reactivity is calculated using the Boolean rule for different time steps, the neutron density is supposed that contains Gaussian noise around of the mean values. There are four terms of convolution sum between the nuclear density population and the impulse response. The convolution sum represents a finite impulse response filter. The different numerical experiments show that it is possible to reduce the fluctuations using the proposed method.
