RIEF論文:Reassessing the safety of nuclear power (S. Wheatley et al.,)

 We summarize the results of a recent statistical analysis of 216 nuclear energy accidents and incidents (events). The dataset is twice as large as the previous best available. We employ cost in US dollars as a severity measure to facilitate the comparison of different types and sizes of events, a method more complete and consistent that the industry-standard approach.

  Despite significant reforms following past disasters, we estimate that, with 388 reactors in operation, there is a 50% chance that a Fukushima event (or more costly) occurs every 60–150 years. We also find that the average cost of events per year is around the cost of the construction of a new plant.

 This dire outlook necessitates post-Fukushima reforms that will truly minimize extreme nuclear power risks. Nuclear power accidents are decreasing in frequency, but increasing in severity.

 論文は「Reassesing the safety of nuclear power」で、「Energy Research & Social Science」の最新号に掲載された。論文は、これまで世界中で発生した216の原発事故を対象として統計的分析を行った。その結果、原発事故発生の頻度は1986年のチェルノブイリ原発事故後、顕著に下がっているとしている。
