摘要
本文阐述了国外核材料安全保障非破坏性分析研究与发展的最新情况,包括技术开发的国际合作概况和部分重要研究课题的进展:(1)γ能谱法测定钚同位素丰度;(2)钚溶液的浓度测量技术;(3)混合式K-边界密度计/XRF;(4)乏燃料核查仪器;(5)分段γ吸收扫描法;(6)无源中子符合计数法测定钚含量;(7)有源中子质询法。
The recent progress of research and development on NDA in safeguarding nuclear materials is described in this paper, including the general information about international cooperation in technique developments and some important research topics as follows: (1) plutonium isotopic measurements by gamma-ray spectrometry; (2) plutonium concentration measurements for solution samples; (3) hybrid K-edge densitometer/XRF. (4) spent fuel verification techniques; (5) segmented gamma-scanner; (6) passive neutron coincident counting for plutonium measurements; (7) neutron interrogation methods.
