KINETIC PARAMETERS CALCULATION DURING FIRST CYCLE OF THE WWER-1000 REACTOR CORE
Determination of the effective delayed neutron fraction (βeff) and neutron generation time (Λ), on account of their important role in the reactivity transients analysis, safety, and control of nuclear reactors, is of the great importance in the reactor physics calculations. In this paper, evaluation of the kinetic parameters (effective delayed neutron fraction and prompt neutron lifetime) in PWRs is calculated. Software was developed to automate the procedure of kinetic parameters calculations. We used both a deterministic and a probabilistic method for calculation of the delayed neutron parameters. The results performed well in comparison to the reference.
