Fukushima Daiichi nuclear disaster
The Fukushima Daiichi nuclear disaster (福島第一原子力発電所事故 Fukushima Dai-ichi (pronunciation) genshiryoku hatsudensho jiko) wis an energy accident at the Fukushima I Nuclear Power Plant in Fukushima, initiatit primarily bi the tsunami follaein the Tōhoku yirdquauk on 11 Mairch 2011. Immediately efter the yirdquauk, the active reactors automatically shut doun thair sustained fission reactions. Houever, the tsunami destroyed the emergency generators cuilin the reactors, causin reactor 4 tae owerheat frae the decay heat frae the fuel rods. The insufficient cuilin led tae three nuclear meltdouns an the release o radioactive material beginnin on 12 Mairch. Several hydrogen-air chemical explosions occurred atween 12 Mairch an 15 Mairch.

A vent in Unit 2's wall, wi watter vapor/"steam" clearly veesible, preventit a seemilar lairge explosion. Drone owerflichts on 20 Mairch capturt clearer images.

As reported earlier, a 400 millisieverts (mSv) per hour radiation dose observed at Fukushima Daiichi occurred between 1s 3 and 4. This is a high dose-level value, but it is a local value at a single location and at a certain point in time. The IAEA continues to confirm the evolution and value of this dose rate. It should be noted that because of this detected value, non-indispensable staff was evacuated from the plant, in line with the Emergency Response Plan, and that the population around the plant is already evacuated.Cite uses deprecated parameter
