Abstract

Abstract

Considering non-homogeneous fast neutron environment and material irradiation effects, numerical simulation of typical 17×17 fuel assembly overall deformation is preliminary realized based on assumptions and simplification. Under the inputs of large fast neutron fluence and fast neutron fluence gradient given in this paper, simulation results indicate that the fuel assembly has low stress level, but the control rod drop and refueling are affected by fuel assembly irradiation deformation.
