对反应堆压力容器（RPV ）钢的辐照脆化进行预测是保证核电站长寿期安全运行的重要方法。通过深入分析国外已有RPV钢的辐照脆化预测模型，揭示了已有参数化预测模型的不足，在此基础上建立了新的预测模型PM IE-2012。利用辐照监督数据对PM IE-2012的可靠性进行评价，结果表明，PM IE-2012对RPV钢的辐照脆化预测具有较高的准确性和可靠性。

The study on prediction model of irradiation embrittlement for reactor pres-sure vessel (RPV ) steel is an important method for long term operation .According to the deep analysis of the previous prediction models developed worldwide ,the drawbacks of these models were given and a new irradiation embrittlement prediction model PMIE-2012 was developed .A corresponding reliability assessment was carried out by irradia-tion surveillance data .The assessment results show that the PMIE-2012 have a high reliability and accuracy on irradiation embrittlement prediction .
