压水堆燃料棒辐照行为模型研究

Modeling of PWR Fuel Rod Irradiation Behaviour

针对压水堆燃料棒辐照行为,建立分析模型,包括热学模型、力学模型、裂变气体释放模型、包壳辐照生长和腐蚀模型。通过与试验数据的对比,验证了模型的有效性。该模型可用于评价燃料棒的结构完整性、开发性能分析软件。

PWR fuel rod irradiation behaviour models have been developed, including thermal model, mechanical model, fission gas release model, cladding irradiation growth and corrosion model. Validation of models has been done by comparing with the test data. Fuel rod irradiation behaviour models can be used for the fuel rod structure integrity evaluation and performance analysis code development.
