| 摘 要： | 堆外中子剂量测量技术在反应堆压力容器辐照监督中有广泛的应用。本文介绍了在国内某试验堆上进行的堆外中子剂量测量技术验证试验及其结果。比较了堆外中子剂量测量所用探测片活度的理论计算值、实测值及解谱计算结果,同时分析对比了试验中各辐照位置处中子能谱的理论计算值及解谱结果。结果表明,基于测量值的解谱结果与理论计算结果符合良好。堆外中子剂量测量技术可以有效完成中子能谱测量。

| Abstract: | Ex-vessel neutron dosimetry measurement technique is widely used in reactor pressure vessel exposure damage surveillance. This article introduced the verification of ex-vessel neutron dosimetry measurement technique on a test reactor. The calculated, measued and best estimated activities of ex-vessel neutron dosimeters were compared. Furthermore,analysis of the calculated and best estimated neutron fluence spectrum has been done. The results showed that calculated results and best estimated results were in good agreement. It is concluded that the ex-vessel neutron dosimetry measurement technique is reliable for neutron spectrum measurement. |
