Detection and Analysis of Activity Ratio A(~(134)Cs)/A(~(137)Cs) at Different Altitude of the Fuel Rod

  • 摘要: 在热室中, 用γ扫描装置对秦山核电厂 3× 3 -2考验组件中辐照历史、燃耗及冷却时间不同的两根燃料棒中的铯活度比A(13 4 Cs) /A(13 7Cs)的轴向分布进行了测量, 并利用自行开发的压水堆燃料棒破损特性分析程序FCAC进行了理论计算。结果表明 :辐照和停堆冷却过程中燃料棒中铯原子的轴向迁移可以忽略, 燃料棒中铯活度比的轴向分布由燃耗的轴向分布决定。

     

    Abstract: Axial distribution of activity ratio A ( 134 Cs)/ A ( 137 Cs) along the fuel rod with different burnup level,irradiation history and cooling time is measured by the γ scanning device. As a comparison, this distribution is calculated by the FCAC code used for the fuel rod failure analysis. The calculated values are in agreement with the measured values within a deviation of 12 %.
