Abstract

The paper considers a computational study of the importance function effect on the accuracy of calculating the effec - tive fraction of delayed neutrons, β eff , and generation time of instantaneous neutrons using the MCU Monte Carlo code based on the example of three criticality experiments from the ICSBEP handbook. In the MCU code, the importance function has a piecewise constant form: the computational model is broken down into a finite number of registration objects
