FOREWORD SPECIAL ISSUE ON THE FUKUSHIMA DAIICHI ACCIDENT

摘要

The events that occurred in March of 2011 at the Fukushima Daiichi nuclear power station in Japan, triggered by the Tohoku earthquake and the resulting tsunami, again marked a decisive time for the worldwide nuclear power industry. As many of us know, the loss of on-site and off-site power combined with the loss of emergency diesel generators due to water ingress initiated a post-scram emergency response challenge to maintain core cooling in these boiling water reactor plants. Ultimately, we now know that there are three partially to fully melted cores, following several hydrogen explosions. The impacts and analysis by the nuclear technical community of the sequence of events that followed the earthquake and tsunami will be studied for many years to come, with the intent of avoiding future incidents, both similar and different. Immediately after the situation in Japan had stabilized, researchers and analysts in the nuclear industry began using their tools to try to better understand the nature of the sequence of events and the outcomes from the accident.
