摘　　要：采用总γ和无源中子测量方法建立了叉形探测器。叉形探测器可用于后处理和贮存工厂中ＰＷＲ和ＢＷＲ型的乏燃料组件的燃耗、冷却时间、总钚和总裂变物质含量的测定。A fork detector has been constructed by making use of gross gamma and passive neutron methods. The detector can been used to determine the burnup, cooling time and the contents of whole plutonium and whole fission material in spent fuel assemblies of the PWR and BWR types at a reprocessing and storage facility.

关 键 词：乏燃料组件 叉形探测器 无损测量 Γ射线 中子
