Abstract: In this study, we show a study to solve the point kinetic equations using the Z-transform. It is possible to decrease the fluctuations during the calculation of the reactivity in nuclear reactors starting from the inverse point kinetic equation and simulating noise with a Gaussian distribution around the average value of the neutron population density. For such cases, we use two filters simultaneously. The Finite Impulse Response (FIR) filter and the first-order delayed low-pass filter. We show that it is possible to reduce the fluctuations during the calculation of reactivity in order to achieve a more precise value compared to other methods that exist in the literature.
