| Abstract: | This paper deals with the problem of computing the feedback reactivity in the frequency domain codes as the LAPUR code. First, we explain how to calculate the feedback reactivity in the frequency domain using slab-geometry (1D) kinetics, also we show how to perform the coupling of the 1D kinetics with the thermal–hydraulic part of the LAPUR code in order to obtain the density to reactivity feedback coefficients, the power to reactivity feedback coefficients and the inlet temperature to reactivity feedback coefficients for the different channels. |
