The Fukushima nuclear accident was a major nuclear accident at the Fukushima Daiichi nuclear power plant in Ōkuma, Fukushima, Japan which began on March 11, 2011. The proximate cause of the accident was the 2011 Tōhoku earthquake and tsunami, which resulted in electrical grid failure and damaged nearly all of the power plant's backup energy ...

Fukushima Daiichi Accident. Updated Monday, 29 April 2024. Following a major earthquake, a 15-metre tsunami disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident beginning on 11 March 2011. All three cores largely melted in the first three days.

During their visit, AP journalists saw 30 giant tanks for sampling and analyzing the water for safety checks. A concrete facility for diluting the water after it is treated and tested is in the final stages of construction. From there, the water will be released via an undersea tunnel. The plant’s operator, Tokyo Electric Power Company Holdings, ai...
A magnitude 9.0 quake on March 11, 2011, triggered a massive tsunami that destroyed the plant’s power supply and cooling systems, causing reactors No. 1, 2 and 3 to melt and spew large amounts of radiation. Water used to cool the reactors’ cores leaked into the basements of the reactor buildings and mixed with rainwater and groundwater. The 130 ton...
Fukushima Daiichi has struggled to handle the contaminated water since the 2011 disaster. The government and TEPCO say the tanks must make way for facilities to decommission the plant, such as storage space for melted fuel debris and other highly contaminated waste. The tanks are 96% full and expected to reach their capacity of 1.37 million tons in...
Local fishing communities say their businesses and livelihoods will suffer still more damage. Neighboring countries such as China and South Korea and Pacific Island nations have raised safety concerns. “It would be best if the water isn’t released, but it seems unavoidable,” said Katsumasa Okawa, owner of a seafood store in Iwaki, south of the plan...
Massive amounts of fatally radioactive melted nuclear fuel remain inside the reactors. Robotic probes have provided some information but the status of the melted debris is largely unknown. Akira Ono, who heads the cleanup as president of TEPCO’s decommissioning unit, says the work is “unconceivably difficult.” Earlier this year, a remote-controlled...
Ono says the goal is a good “guidepost” but too little is known. The government has stuck to its initial 30-40 year target for completing the decommissioning, without defining what that means. An overly ambitious schedule could result in unnecessary radiation exposures for plant workers and excess environmental damage, said Ryo Omatsu, an expert on...
