As a consequence of an earthquake and tsunami in the early afternoon, the Fukushima Daiichi nuclear power plant, on Japans Atlantic coast, began to lose integrity. In the hours and days that followed efforts to control a reactor and spent fuel ponds failed. Dangerous radioactive isotopes contaminated the region around the plant, and there was significant run of contaminated water into the nearby ocean.
Some states reconsidered whether to build planned nuclear plants. Nuclear regulators throughout the world focused on existing and proposed nuclear plant designs. Prior projections of reliance on nuclear to generate electricity, avoiding greenhouse gas emissions, were immediately in doubt. A series of studies documented design and response failures, but as parts of the plant remained inaccessible such studies were not the last word. Press reports suggested it might take 40 years before the plant was thoroughly decommissioned and the site abandoned.
