Arnie Gundersen, former nuclear engineer, Mar 11, 2017 (emphasis added):
The scientific impact of the triple meltdown at Fukushima Daiichi is an ongoing disaster that was never envisioned by the engineers who created and designed these atomic reactors and countries who built them… no country in the world with nuclear power reactors was prepared for the explosive radioactive contamination of Fukushima Daiichi. Over and over, people ask me about what happened inside the plants and what is still happening inside with robots fried by radiation, corium that can’t be found, and massive amounts of radioactivity migrating to sensitive estuaries, aquifers, contaminating all the ground water, and polluting the Pacific Ocean… No one has discovered where the nuclear cores have disappeared to. The $400,000,000 “ice wall” continues to leak… Moreover, the cover-up continues, with the health effects from radiation being camouflaged as stress related illnesses… I decided to share the photographs I took last year in Japan… these photos cannot adequately convey the scientific and human impact of the worst industrial cataclysm in the history of the world… [R]adioactive isotopes will be extreme hazards for 250,000 years, of course no one knows when it will end.
