2011 – Fukushima Daiichi Nuclear Disaster
Mar 11 – Mar 12 all-day

March 11, 2011 is the anniversary of the Fukushima Daiichi nuclear power plant disaster that occurred in northeast Japan following a magnitude-9 earthquake. The earthquake generated a large tsunami that struck the coastal power plant and destroyed the generators responsible for cooling 3 of its 6 nuclear reactors. This resulted in a meltdown of the reactors and a release of radioactive material into both the atmosphere and surrounding water.

This disaster prompted a review of nuclear power plant safety and security around the world, including a review of American coastal power plants in California. The following document from the HSDL collection outlines one aspect of U.S. response to the disaster: Fukushima Fallout: Regulatory Loopholes at U.S. Nuclear Plants
