福岛第一核电站退役的风险管理是一个巨大的挑战。在本研究中，为退役工作制定了风险管理框架。应用于3号机组乏燃料池燃料组件回收。整个检索工作分为三个阶段：准备、检索、运输和存储。首先，确立了终点，制定了成功路径。然后，可能的威胁，这是内部/外部和技术/社会/管理，识别和选择。“什么地方会出错？”是一个关于失败场景的问题。对每种情况的可能性和后果进行了粗略估计。整个退役项目将持续几十年，因此，长远的眼光是重要的。应该强调的是，我们并不总是有足够的这方面的知识和经验。预计退役可以在支持拟议的风险管理框架方面取得稳定和良好的进展。因此，需要进行风险评估和管理，并且需要根据有关退役工程的最新信息和知识更新该过程。
Risk management of the Fukushima Daiichi Nuclear Power Station decommissioning is a great challenge. In the present study, a risk management framework has been developed for the decommissioning work. It is applied to fuel assembly retrieval from Unit 3 spent fuel pool. Whole retrieval work is divided into three phases: preparation, retrieval, and transportation and storage. First of all, the end point has been established and the success path has been developed. Then, possible threats, which are internal/external and technical/societal/management, are identified and selected. “What can go wrong?” is a question about the failure scenario. The likelihoods and consequences for each scenario are roughly estimated. The whole decommissioning project will continue for several decades, i.e., long-term perspective is important. What should be emphasized is that we do not always have enough knowledge and experience of this kind. It is expected that the decommissioning can make steady and good progress in support of the proposed risk management framework. Thus, risk assessment and management are required, and the process needs to be updated in accordance with the most recent information and knowledge on the decommissioning works.
