An integrated approach of model simplification for high burnup spent nuclear fuel is proposed based onmaterial calibration using optimization. The spent fuel rods are simplified into a beam with a homogenousisotropic material. The proposed approach of model simplification is applied to fuel rods with twokinds of interfacial configurations between the fuel pellets and cladding. The differences among thegenerated models and the effects of interfacial bonding efficiency are discussed. The strategy of modelsimplification adopted in this work is to force the simplified beam model of spent fuel rods to possess thesame compliance and failure characteristics under critical loads as those that result in the failure ofdetailed fuel rod models. It is envisioned that the simplified model would enable the assessment of fuelrod failure through an assembly-level analysis, without resorting to a refined model for an individual fuelrod. The effective material properties of the simplified beam model were successfully identified using theintegrated optimization process. The feasibility of using the developed simplified beam models in dynamicimpact simulations for a horizontal drop condition is examined, and discussions are provided
