The earthquake triggered a powerful tsunami, with 13- to 14-meter-high waves damaging the nuclear power plant's emergency diesel generators, leading to a loss of electric power. The proximate cause of the disaster was the Tōhoku earthquake and tsunami, which remains the most powerful earthquake ever recorded in Japan. On 11 March 2011, a nuclear accident occurred at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan. Ĭontroversy surrounds the health effects, but reports indicate no significant increase in health issues for babies born after the accident. TEPCO worked on fuel removal and cleanup, and the decommissioning process is expected to take 30 to 40 years. Investigations faulted lapses in safety and oversight, revealing failures in risk assessment and evacuation planning, with the Tokyo Electric Power Company (TEPCO) admitting to not taking necessary measures for fear of legal action or protests. Following the disaster, at least 164,000 residents of the surrounding area were displaced (either voluntarily or by evacuation order), although many have since returned to their homes. The Fukushima nuclear disaster was a major nuclear disaster, which began on Mawith the 2011 Tōhoku earthquake and tsunami, in which nearly all of the power plant's backup energy sources were damaged, resulting in three nuclear meltdowns, three hydrogen explosions, and the release of radioactive contaminants into the surrounding environment. ġ6 with physical injuries due to hydrogen explosions, Ģ workers taken to hospital with possible radiation burns Īppearance of Unit 3 after the explosion on 15 March 2011. Autopsy revealed that the two most likely died from the force of impact as the tsunami hit while they were sent down to the basement. Two bodies of employees who were working there at the time were discovered in the basement during the aftermath as reactor four was kept under control. One confirmed cancer death attributed to radiation exposure by the government for the purpose of compensation following opinions from a panel of radiologists and other experts. Water vapour/"steam" venting prevented a similar explosion in Unit 2. Hydrogen-air explosions in Units 1, 3, and 4 caused structural damage.
