Adaptation of FEMAXI-6 Code for Fuel Rods of RBMK-1500 and Employment of Uncertainty and Sensitivity Analysis Available to Purchase

This paper provides information about possibility to apply FEMAXI-6 code for RBMK-1500. According to RBMK-1500 specification new thermal properties and models responsible for thermal analysis (thermal conductivity and heat capacity) were included in FEMAXI-6 code. Using adapted FEMAXI-6 code model of RBMK-1500 fuel rod was developed and tested by employing uncertainty and sensitivity analysis. The processes of fuel rods during normal plant operation were modelled. The received results were compared with calculations performed by specialists from Kurchatov Institute (designers of RBMK). The reasonable agreement of both calculation results shows that adapted FEMAXI-6 code and developed model are suitable for future analysis of processes in fuel rods of RBMK-1500.
