Title (EN) METHOD AND SYSTEM FOR INSPECTING SPECIAL NUCLEAR MATERIAL
(FR) PROCÉDÉ ET SYSTÈME POUR INSPECTER UN MATÉRIAU NUCLÉAIRE PARTICULIER
(ZH) 一种检测特殊核材料的方法和系统
Abstract: front page image
(EN)A method for inspecting special nuclear material and a system for inspecting special nuclear material using the method are disclosed. The method includes that an object to be inspected (7) is inspected by utilizing both of the irradiation-induced fission characteristic and the thermal neutron induced fission characteristic of the special nuclear material (8). The method further includes that a high-density and/or high atomic number area of the object to be inspected (7) is deemed as a suspicion area to be inspected at first.
(FR)L'invention porte sur un procédé pour inspecter un matériau nucléaire particulier et sur un système pour inspecter un matériau nucléaire particulier à l'aide du procédé. Le procédé comprend le fait qu'un objet devant être inspecté (7) est inspecté en utilisant à la fois la caractéristique de fission induite par irradiation et la caractéristique de fission induite par des neutrons thermiques du matériau nucléaire particulier (8). Le procédé comprend de plus le fait qu'une zone de haute densité et/ou de nombre atomique élevé de l'objet devant être inspecté (7) est considérée comme étant une zone suspecte devant être inspectée en premier.
