Método híbrido para disminuir las fluctuaciones en el cálculo de la reactividad nuclear

Abstract

The project expose and proposes a hybrid method, which allows to reduce fluctuations in reactivity calculation of the point kinetics equations. This work is carried out several experiments or simulations for different forms of nuclear power and a time step of calculating T = 0.01s and real time tr =1s . The mean nuclear power is affected by a Gaussian random noise with a standard deviation of σ= 0.1. To solve this problem the combined implementation of the filters is presented: FIR, Low Pass of the first order delay and Exponential as a hybrid method. Similarly in this project is performed by first reducing fluctuations in reactivity using the Savitzky-Golay (SG) filter, both methods of filtering can improve the value of the maximum differences or absolute error average are reported in the literature.
