Nuclear and Radiation Safety| Резюме: | Different methods of modeling of most loaded fuel pin are presented at the work. Calculation studies are performed on example of accident related to VVER-1000 cluster rod ejection with using of spatial kinetic code DYN3D that uses nodal method to calculate distribution of neutron flux in the core. Three methods of modeling of most loaded fuel pin are considered — flux reconstruction in fuel macrocell, pin-by-pin calculation by using of DYN3D/DERAB package and by introducing of additional “hot channel". Obtained results of performed studies could be used for development of calculation kinetic models during preparing of safety analysis report. |
