Excess steam from the drywell enters the wetwell water pool via downcomer pipes. SFP: spent fuel pool area. SCSW: secondary concrete shield wall. 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.
- 11 March 2011; 12 years ago
- INES Level 7 (major accident)
- 1 confirmed from radiation (lung cancer, 4 years later), and 2,202 from evacuation.
A nuclear disaster occurred there after a 9.0 magnitude earthquake and subsequent tsunami on 11 March 2011. The earthquake triggered a scram shut down of the three active reactors, and the ensuing tsunami crippled the site, stopped the backup diesel generators, and caused a station blackout.
Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen isotopes ), combine to form one or more different atomic nuclei and subatomic particles ( neutrons or protons ). The difference in mass between the reactants and products is manifested as either the release or absorption of energy.

On 29 August, an IAEA expert mission led by Rafael Grossi left Vienna. On 1 September 2022, the IAEA team passed through the frontline in armoured white land cruisers, where they were held at the first checkpoint outside Zaporizhzhia because of shelling reports. In the previous few days the staff town of Enerhodar had been under intense shelling. G...
On 6 September, the IAEA issued a report on the nuclear facilities in Ukraine. The report's main conclusion was that the occupation of the plant by Russian armed forces violates all seven pillars of nuclear safety 1. In March during the Russian siege of the plant damaged training center, laboratory and administrative building were damaged by projec...
After the publication of the IAEA report, as shelling of the plant continued, the plant was operating disconnected from the grid in "island mode" for a few days. In that mode the last operational reactor was used to power the plant's own safety systems. On 11 September, at 3.14am, the sixth and final reactor was disconnected from the grid, "complet...
On 5 October, the Associated Pressreported that in an interview, Energoatom President Petro Kotin said that the energy company could restart two of the reactors within days, with a decision to be made as early as 12 October, to protect safety installations. Kotin said that due to low temperatures over the coming winter, safety equipment will be dam...
Russia’s Ministry of Defence reported a Ukrainian attempt to land troops at the plant from across the Dnipro River on 19 October 2022, reporting that Ukraine lost 90 troops and 14 boats in the attempt. Ukraine denied this at the time. However The Times later confirmed the operation in 2023, after interviewing Ukrainian participants, reporting that ...
On 19 and 20 November the nuclear power plant was subjected to the most intense bombing in months, as the head of the IAEA reported. IAEA experts reported more than a dozen blasts, with "damage in several places", but none so far critical for nuclear safety as the external power supplies were not affected and radiation levels remained normal.The IA...
On 30 May 2023, Rafael Grossi, IAEA Director General, updated the United Nations Security Councilon the situation. Military activities had continued with the loss of off-site power forcing the use of emergency diesel generators on seven occasions to operate essential spent fuel and reactor cooling, most recently a week previously. It had not been p...
On 6 June 2023, the Kakhovka Dam was breached causing the depletion of the plant's main water source, the Kakhovka Reservoir, which is expected to be too low to use within a few days, though there are several alternative sources adequate for essential cooling water while the reactors are in the current shutdown state. The IAEA Director General said...
It was reported that the sixth reactor was being kept in hot shutdown at 200 °C, to make it easier to restart if necessary and to provide winter heating to Enerhodar. Two days later, on 8 June, the sixth reactor was put into cold shutdown as a safety precaution due to nearby flooding and shelling.As of 4 July the 750 kV electric grid has been recon...
In June and July 2023 Ukraine and Russia frequently blamed each other of preparing a sabotage or false flag operation at the plant. On 21 June IAEA confirmed "previous placement of mines outside the plant perimeter" and also "at particular places inside", but assessed these as not having a significant impact on the plant's operational safety. On 5 ...
The European Organization for Nuclear Research, known as CERN ( / sɜːrn /; French pronunciation: [sɛʁn]; Conseil européen pour la Recherche nucléaire ), is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954, it is based in Meyrin, western suburb of Geneva, on the ...
On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki. The bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in an armed conflict. Japan surrendered to the Allies on 15 August, six days after the bombing of ...
On 3 April 2024, at 07:58:11 NST (23:58:11 UTC on 2 April), a Mw 7.4 earthquake struck 18 km (11 mi)[2] south-southwest of Hualien City, Hualien County, Taiwan. At least 17 people were killed and over 1,100 were injured in the earthquake. It is the strongest earthquake in Taiwan since the 1999 Jiji earthquake,[3] with three aftershocks above ...
