Numerical Study of the Dynamic Strength of RBMK-1000 Stack with Fuel Channel Rupture

  • Published:
Atomic Energy Aims and scope

The strength of the stack in a RBMK-1000 reactor facility with a rupture of a fuel channel is studied. Local models of unirradiated and irradiated stack, comprising an assembly consisting of 81 columns, and a complete model of the original stack are developed to calculate the parameters of RBMK-1000 core degradation. Numerical studies of the nonstationary stress-strain state of the initial unirradiated stack and the stack degraded by irradiation one year after the repair-restorative work, which confirm the core strength to be adequate, are presented.
