Abstract

Abstract

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.
