Results of daily power’s maneuvering regime simulation that were proposed for 2nd unit of Khmelnitsky NPP are presented. Calculations were performed for campaign’s moments 100 and 150 fpd. Modeling was performed by spatial computer code DYN3D, that uses nodal method for neutron flux calculation. Calculated assessment of marginal value’s compliance of peaking factors, linear pin power, control rods efficiency and minimal axial offset deviation were performed. Comparative analysis of experimental data, that were obtained during maneuvering regime’s testing on 2nd unit of Khmelnitsky NPP, and modeling data are presented.
