##东电公司临时取消福岛核电站核燃料熔块首次取出作业
**东京，8月22日** – 东京电力公司（东电）原定于今日首次试验性地从福岛第一核电站厂房中取出核燃料熔块，但由于取出设备出现安装失误，东电公司临时决定推迟取出作业。
福岛第一核电站1号至3号核电机组在2011年3月的核事故中发生堆芯熔毁，熔化的核燃料与周围的设施结构构成了具有极强辐射性的核燃料熔块，人员难以接近。据预计，核燃料熔块约有880吨，如何对其进行清理被视为废堆作业的最大难题。
东电公司原本计划今日从2号机组入手，进行首次试验性取出核燃料熔块。有关人员当天早上临近7时30分的时候启动了准备工作，但由于取出设备出现安装失误，东电公司在临近9时的时候临时决定将取出作业延期。东电公司表示，目前正在确认详细情况，23日之后的相关安排目前仍是一个未知数。
东电公司最初的计划是在2021年之前启动从福岛第一核电站核电机组厂房取出核燃料熔块的作业，这一工作已经大幅延后。中央政府和东电公司都指出，了解与核燃料熔块的性质、状态等有关的数据对于制定全面取出核燃料熔块的方案至关重要，是推进废堆作业的关键。东电公司何时能成功踏出试验性取出核燃料熔块这第一步，令人关注。
此次取出作业的推迟再次凸显了福岛核事故清理工作的复杂性和挑战性。尽管东电公司已经投入大量人力物力进行清理工作，但由于核燃料熔块的放射性极强，且其性质和状态尚不明确，清理工作进展缓慢。
此次事件也引发了公众对于核安全和核废料处理的担忧。专家指出，福岛核事故的清理工作将是一个漫长而艰巨的过程，需要政府、企业和公众的共同努力。

##Fukushima Fuel Removal Operation Abruptly Cancelled
**Keywords:** Fukushima Daiichi Nuclear Power Plant, fuel removal, postponement
**Tokyo, August 22** – Tokyo Electric Power Company (TEPCO) has abruptly cancelled its planned first experimental removal of melted nuclear fuel debris from the Fukushima Daiichi Nuclear Power Plant, citing an installation error in the removal equipment.
The Fukushima Daiichi Nuclear Power Plant’s Units 1, 2, and 3 experienced coremeltdowns during the March 2011 nuclear accident. The melted nuclear fuel mixed with surrounding structural materials, forming highly radioactive fuel debris that is inaccessible to humans. An estimated 880 tons of fuel debris remain,posing a significant challenge to decommissioning efforts.
TEPCO had planned to begin the first experimental removal of fuel debris from Unit 2 today. Preparations began around 7:30 AM, but an installation error in the removal equipment ledto a postponement of the operation around 9:00 AM. TEPCO stated that they are currently investigating the situation and the schedule for future operations remains uncertain.
TEPCO’s initial plan to begin removing fuel debris from the Fukushima Daiichi reactor buildings by 2021 has been significantly delayed.Both the central government and TEPCO have emphasized the importance of obtaining data on the nature and condition of the fuel debris for developing a comprehensive removal plan, a critical step in the decommissioning process. The delay raises concerns about when TEPCO will be able to successfully take this first step in the experimental removal offuel debris.
The postponement of this operation further underscores the complexity and challenges of the Fukushima nuclear accident cleanup. Despite significant resources dedicated to the cleanup, the highly radioactive nature and unknown characteristics of the fuel debris have slowed progress.
This incident has also raised public concerns about nuclear safety and waste management. Experts have emphasized thatthe Fukushima cleanup will be a long and arduous process requiring the combined efforts of the government, industry, and the public.
