Abstract

This paper presents a new method for the calculation of reactivity through the nuclear power history term in the inverse equation of point kinetics. In this method, the reactivity can be written using Boole´s composite rule, which gives rise to four convolution sum terms between the nuclear power and the impulse response, with special characteristics typical of linear systems. Each convolution sum represents a filter of finite response, FIR. From the cases studied, our results provide better approximations when compared to existing methods in the literature.
