Study of Effects Caused by the Neutron Value Function on Kinetic Functionals Using the MCU Software
The results of calculating the βeff effective fraction of delayed neutrons and the Λ lifetime of prompt neutrons, both when taking into account and excluding the value function, are presented. The analysis, concerning the effects of accounting for the neutron value function at various degrees of its expansion, as well as depending on the physical and geometric parameters of the system, is conducted. The calculations were performed for twelve experiments from the ICSBEP collection. The analysis of the results states the necessity of accounting for the value function in small systems with a reflector and a large number of neutrons. No accounting for the value function is required for estimating the kinetic functionals in systems that are close to infinite.
