论文摘要
我们已经通过称为宇宙MUON射线照相的方法研究了福基岛Daiichi核电站的核燃料组件的状态。在这项研究中，将MUON跟踪探测器放置在反应堆建筑物外。我们成功地通过反应堆建筑物的混凝土壁确定了反应堆复合物的内部结构，例如反应堆遏制容器，压力容器和反应堆建筑物的其他结构。我们发现，压力容器内的原始燃料加载区域中缺少大量燃料组件。可以自然解释的是，大多数核燃料都融化并掉落到压力容器的底部甚至下方。
We have investigated the status of the nuclear fuel assemblies in Unit-1 reactor of the Fukushima Daiichi Nuclear Power plant by the method called Cosmic Muon Radiography. In this study, muon tracking detectors were placed outside of the reactor building. We succeeded in identifying the inner structure of the reactor complex such as the reactor containment vessel, pressure vessel, and other structures of the reactor building, through the concrete wall of the reactor building. We found that a large amount of fuel assemblies was missing in the original fuel loading zone inside the pressure vessel. It can be naturally interpreted that most of the nuclear fuel was melt and dropped down to the bottom of the pressure vessel or even below.
