Fukiushima Daiichi: 10 years on

It was a rather normal day back on March 11, 2011, at the Fukushima Daiichi nuclear plant before 2:45 p.m. That was the time when the Great Tohoku Earthquake struck, followed by a massive tsunami that caused three reactor meltdowns and forever changed the nuclear power industry in Japan and worldwide. Now, 10 years later, much has been learned and done to improve nuclear safety, and despite many challenges, significant progress is being made to decontaminate and defuel the extensively damaged Fukushima Daiichi reactor site. This is a summary of what happened, progress to date, current situation, and the outlook for the future there.

The atmospheric dispersion model (Tritium-EESAD) was further modified so as to be able to predict tritium concentration in plant tissue free water (TFWT), organically-bound tritium (OBT) and groundwater. The modified model was validated by participating in the Pine Tree Scenario of the IAEA EMRAS program. Monitoring data were disclosed after submission of model predictions and compared with them. Overall time trends of the predicted tritium concentrations in almost all calculation endpoints agreed well with those of observations within a factor of two.
