Inverse Kinetics For Subcritical Systems with Variating External Sources

Abstract

With the rise of a new generation of ADS (Accelerator-Driven System) nuclear reactors it is important to have a rapid and accurate prediction of the variation in reactivity during a possible variation in the intensity of external sources. This paper presents a formulation for the calculation of reactivity in subcritical systems using the inverse method as related only to nuclear power derivatives. One of the applications of the proposed method is the possibility of developing reactimeters that allow the continuous monitoring of subcritical systems.
