摘要2019年2月，东京电力公司和东芝公司设计了一种可以处理碎片的机器人，对福岛第一（1F）2号机组的主安全壳（PCV）进行了试验调查，并发布了一段视频。该视频包含了许多有价值的信息，可以与日本原子能机构（JAEA）最近进行的BWR控制叶片退化测试的结果进行比较。在假设的1F 2号机组模拟条件下进行试验期间，观察到试验样品的复杂行为，主要形成三种类型的碎片。可能的机制管理的1楼2号机组碎片的形成和可能的方式，他们的搬迁进行了讨论。
ABSTRACT In February 2019, TEPCO and TOSHIBA designed a robot that can handle the debris, performed a trial investigation of primary containment vessel (PCV) of the Fukushima Dai-Ichi (1F) Unit 2 and published a video. The video contained lots of valuable information which can be compared with results of BWR control blade degradation tests recently performed in Japan Atomic Energy Agency (JAEA). During the test under postulated 1F Unit 2 simulated conditions a complex behaviour of the test sample with the formation of mostly three types of debris was observed. Possible mechanisms governing the 1F Unit 2 debris formation and possible ways of their relocation are discussed.
