一年多前发生在福岛第一核电站的重大核事故是四个相互关联的因素综合作用的结果：选址、外部危险评估和场地准备、电力公司的风险管理方法和反应堆基本设计。反应堆事故是由9级地震引发的，随后发生了更具破坏性的海啸。海啸纵深防御战略不足导致三个机组的堆芯严重受损，并向环境释放放射性物质。本文概述了导致事故的一系列事件，以及目前控制和管理释放的放射性物质的努力。
The major nuclear accident at the Fukushima Daiichi nuclear power plant more than one year ago was the result of a combination of four inter-related factors: site selection, external hazard assessment and site preparation, the utility's approach to risk management, and fundamental reactor design. The reactor accident was initiated by a magnitude 9 earthquake, followed by an even more damaging tsunami. An insufficient tsunami defense-in-depth strategy led to significant core damage in three units and radioactive release to the environment. This paper provides a summary of the sequence of events that led to the accident and current efforts to contain and manage the released radioactivity.
