标题： Imaging the Inner Structure of a Nuclear Reactor by Cosmic Muon Radiography

摘要： 我们通过μ子成像技术研究了日本原子能公司（JAPC）在日本东海的核反应堆的内部结构。在本研究中，μ子探测器被放置在反应堆建筑外部。通过检测穿透反应堆建筑墙壁的宇宙μ子，我们成功识别了如安全壳、压力容器和其他反应堆结构等物体。我们还观察到了一种重物质的集中区域，这可以归因于存放在核燃料储存池中的核燃料组件。 显示英文摘要

摘要： We studied the inner structure of the nuclear reactor of the Japan Atomic Power Company (JAPC) at Tokai, Japan, by the muon radiography. In this study, muon detectors were placed outside of the reactor building. By detecting cosmic muons penetrating through the wall of the reactor building, we could successfully identify the objects such as the containment vessel, pressure vessel, and other structures of the reactor. We also observed a concentration of heavy material which can be attributed to the nuclear fuel assemblies stored in the nuclear fuel storage pool.
