On the 11th of March 2011, Japan was struck with an earthquake of magnitude nine on the Richter scale and the following tsunami flooded the nuclear power plant Fukushima-Daiichi. The power plant consisted of six reactors of which three were operating at the time and three were in cold shutdown because of scheduled refueling. The plant’s connection to the electrical grid was severely damaged in the earthquake resulting in a complete loss of off-site power supply and a station blackout. Hence, the reactor cooling was switched to the emergency diesel generators located in the basement part of the reactors. Forty minutes after the earthquake, the site was flooded by a tsunami, damaging almost all of the emergency generators, and leaving only one in unit 6 operational. Subsequently, units 1-4 lost all cooling sources, while units 5 and 6 were connected to the only operational diesel generator located in unit 6. From units 1-4, a substantial number of radioactive particles were released into the atmosphere because of the explosions and directly released into the ocean. In the period between the 20th of March and the beginning of May, the reactors were finally reconnected to the grid. The power plant is still being decommissioned today. The Fukushima nuclear disaster greatly affected the image of nuclear energy around the world, especially in Japan. The research done after the disaster shows a rapid increase in negative perception of nuclear energy among the questioned. The impact of the disaster is still seen to this day considering the number of nuclear power plants being shut down because of fear of another accident happening. Today, recent technologies are being implemented into nuclear power plants making them more reliable and safer since the 2011 disaster.
