摘　　要：反应堆压力容器(RPV)辐照脆化问题是制约RPV安全服役的关键,构建辐照损伤预测模型是预测辐照脆化损伤的有效方法。本文通过研究辐照损伤参数化预测模型、结构化预测模型和人工神经网络预测模型等典型辐照损伤模型的构建机理和构建方法,对比了不同预测模型的优缺点。结果表明:基于辐照机理的预测模型构建技术较能反映辐照脆化的物理作用机理,基于此提出了RPV自主预测模型的构建技术路线。The problem of irradiation embrittlement of reactor pressure vessel(RPV)is the key to restrict the safe service of RPV,and the building of irradiation damage prediction model is an effective method to predict irradiation embrittlement damage.In this paper,the building mechanisms and methods of typical irradiation damage models such as parameterized prediction model,structured prediction model and artificial neural network prediction model are studied,and the advantages and disadvantages of different prediction models are compared.The results show that the building technology of prediction model based on irradiation mechanism can better reflect the physical mechanism of irradiation embrittlement.Based on this,the construction technology route of RPV independent prediction model is proposed.
