In Reference 1, the authors presented a two-region point kinetic model for reflected reactors based on the Avery-Cohn differential equations. The model was developed for a core region surrounded by a non-multiplying, source-free reflector region. As part of the model development, they also introduced several probability relationships that were essential to calculating the coupling parameters that linked the two regions. Furthermore, they showed how these coupling parameters could be obtained from deterministic transport solutions. In this work, they present a new model that extends the aforementioned two-region kinetic model by including neutron multiplication in both regions. This new model has practical application to any reactor system that has significantly different neutronic properties in two distinct regions of the system--such as a fast breeder reactor consisting of an inner core surrounded by a multiplying blanket of a different composition. From this new model, they derive the inhour equation that is most appropriate for this type of system.
