摘　　要：反应堆压力容器作为压水堆中不可更换的关键设备,其结构完整性与核电厂安全及寿期有着密切关系。通过整合辐照监督数据、构建辐照脆化预测公式及模型,可以有效预测压力容器状态,提高核电厂运行的安全性、经济性。本文在分析研究国外反应堆压力容器辐照监督数据库和辐照脆化预测模型构建详情的基础上,结合我国实际情况,提出了我国建立辐照监督数据库的相关建议。Reactor pressure vessel is the key equipment in pressurized water reactor which cannot be replaced.Its structural integrity is closely related to the safety and cycle-life of nuclear power plant.By integrating the radiation monitoring data and constructing the radiation embrittlement prediction formula and models,the state of pressure vessel can be predicted effectively,and the level of operation safety and economy of nuclear power plant can be improved.Based on the investigation and analysis of the details of the construction of radiation monitoring database and radiation embrittlement prediction models for reactor pressure vessels,some suggestions were proposed on the establishment of radiation monitoring database suitable for the actual radiation monitoring practice in China.
