This disaster caused by two major natural disasters that happen often in this city of Fukushima Daiichi. Future. When the earthquake struck at 2:46 p.m., the Fukushima-Daiichi nuclear power plant, along with at least three others, automatically shut down, sliding control rods — made of materials, like boron, that block neutrons — into the three reactor cores that had been up and running. The Fukushima nuclear accident as a part of a triple disaster was unprecedented in its scale and nature. Though the Fukushima Nuclear Power Plant escaped the earthquake that occured in the Tōhoku region, it was near the Pacific Ocean and thus, was severely hit by the Tōhoku tsunami, which was a direct result of the earthquake. The natural disaster caused the Daiichi nuclear power plant in Fukushima to go into meltdown. unexpected German reaction to the Fukushima Daiichi nuclear disaster, which in-volved the immediate shutdown of almost half of Germany’s nuclear power plants while safety checks were carried out, and a three-month moratorium on extending the lives of others. They were unable to effectively use the Residual Heat Removal systems to cool the reactors for three days. November 8, 2019 . The Daiichi nuclear power plant was in dire straits. Every day since the 2011 Fukushima Daiichi disaster, due to the penetration of groundwater, which caused a radioactive matter leakage, about 170 tons of radioactively contaminated water was produced, containing the radioactive hydrogen isotope: tritium and other substances. A disaster may escalate rapidly to reach unpredicted consequences. Fukushima Nuclear Disaster Congressional Research Service Summary The huge earthquake and tsunami that struck Japan’s Fukushima Daiichi nuclear power station on March 11, 2011, knocked out backup power systems that were needed to cool the reactors at the plant, causing three of them to undergo fuel melting, hydrogen explosions, and radioactive The nuclear accident occurred after the back-to-back natural events that rocked the eastern shore of Japan; first, a 9.0 magnitude earthquake with an epicenter about eighty miles offshore, followed by a tsunami that created waves up to 50 feet in height. The report assesses the causes and consequences of the 11 March 2011 accident at the Fukushima Daiichi Nuclear Power Plant in Japan, which was triggered by a tsunami that followed a massive earthquake. Level 7 on the International Nuclear Event Scale After a tsunami struck the Fukushima Daiichi nuclear plant in Japan eight years ago today, triggering the meltdowns of three reactors, many believed it would result in a public health catastrophe.
