The Fukushima Daiichi nuclear disaster (福島第一原子力発電所事故 Fukushima Dai-ichi (Aboot this soond 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.[6] 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.

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.
