一回路管道活化腐蚀产物放射性活度计算方法

Calculation Method of Radioactivity of Activated Corrosion Products in Primary Circuit Pipeline

对不同理论模型、模型方程及其优缺点等方面进行了综述,结合一回路活化腐蚀产物的迁移特性,推导出一种计算方法,对压水堆一回路管道活化腐蚀产物60Co、58Co的放射性活度进行了评估,通过Pactole计算结果对比论证了该方法的可靠性。

Different theoretical models,model equations,advantages and their disadvantages are reviewed.Combined with the migration characteristics of activated corrosion products in the primary circuit,a calculation method is derived to evaluate the radioactivity of activated corrosion products oCo and 58 Co in the primary circuit of a pressurized water reactor.The reliability of the method is demonstrated by comparing the Pactole calculation results.
