Abstract

This paper presents a new study to reduce fluctuations in the calculation of reactivity. The inverse equation of point kinetics is solved with an approximation in the neutron density history using the Euler-Maclaurin method. An exponential filter is implemented to reduce the fluctuations in the neutron population density. These fluctuations are simulated using a Gaussian noise with zero mean and unity variance around the average power.
