Abstract
Results of thermo-mechanical behavior of fuel pins during daily power’s maneuvering regime that were proposed for 2nd unit of Khmelnitsky NPP are presented. Calculations were performed for campaign’s moments 100 and 150 fpd and for different type of regulation. Calculations of macro-core parameters (Kq, Kv) was performed by spatial computer code DYN3D. Calculations of micro-core parameters (fuel pin power) was performed by computer code DERAB. Calculations of thermo-mechanical behavior of fuel pins was performed by computer code TRANSURANUS.
