福岛一号核电站发生严重事故后，涡轮机厂房及周边地区已产生大量受污染的积水。这种快速通信报告了堆芯中放射性核素存量的计算、积水中测量存量的收集以及堆芯到积水的放射性核素释放比率的估计。本评价基于2011年6月3日之前获得的数据。结果表明，氚、碘和铯的释放率为几十个百分点，而锶和钡的释放率则小一至两个数量级。福岛事故的这些释放率与TMI-2事故的释放率相当。
After the severe accident in the Fukushima-1 nuclear power plant, a large amount of contaminated stagnant water has been produced in turbine buildings and surrounding areas. This rapid communication reports the calculation of the radionuclide inventory in the core, the collection of the measured inventory in the stagnant water, and the estimation of the radionuclide release ratios from the core to the stagnant water. The present evaluation is based on data obtained before June 3, 2011. It was revealed that the release ratios of tritium, iodine and cesium were several tens of percent, while those of strontium and barium were smaller by one or two orders of magnitude. These release ratios of the Fukushima accident were equivalent to those of the TMI-2 accident.
