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.

Fiscal year 2020 marks the sixth consecutive year that the Hanford Site, in southeastern Washington State, has treated more than 2 billion gallons of groundwater to remove contamination from decades of past operations to produce plutonium for the U.S. nuclear weapons program.

The goal this fiscal year, which ends September 30, is to treat at least 2.4 billion gallons, the Department of Energy reported on September 8.
