An exclusion zone is a territorial division established for various, case-specific purposes. Per the United States Department of Defense , an exclusion zone is a territory where an authority prohibits specific activities in a specific geographic area (see military exclusion zone ). [ 1 ]
The Fukushima nuclear accident was a major nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan, which began on 11 March 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 I and II Nuclear Accidents Overview Map showing evacuation and other zone progression and selected radiation levels. The Japanese reaction occurred after the Fukushima Daiichi nuclear disaster, following the 2011 Tōhoku earthquake and tsunami. A nuclear emergency was declared by the government of Japan on 11 March.
21:40: The evacuation zone around Fukushima I is extended to 20 km, and the evacuation zone around Fukushima II is extended to 10 km. [21] To release pressure within reactor unit 1 at Fukushima I, steam containing water vapor, hydrogen, oxygen and some radioactive material is released out of the unit into the air.
The 2011 Fukushima Daiichi nuclear disaster, the worst nuclear incident in 25 years, displaced 50,000 households after radioactive material leaked into the air, soil and sea. [1] Radiation checks led to bans on some shipments of vegetables and fish. [2] Map of contaminated areas around the plant (22 March – 3 April).
The Fukushima Daiichi plant is connected to the power grid by four lines, the 500 kV Futaba Line (双葉線), the two 275 kV Ōkuma Lines (大熊線) and the 66 kV Yonomori Line (夜の森線) to the Shin-Fukushima (New Fukushima) substation. The Shin-Fukushima substation also connects to the Fukushima Daini plant by the Tomioka Line (富岡線).
The town was evacuated as a result of the Fukushima Daiichi nuclear disaster—being directly downwind from the power plant—and was within the exclusion zone set up in response to the disaster. Following ongoing clean-up efforts, Namie's business district and town hall have reopened, but access to more heavily contaminated western parts of ...
The Fukushima disaster cleanup is an ongoing attempt to limit radioactive contamination from the three nuclear reactors involved in the Fukushima Daiichi nuclear disaster that followed the earthquake and tsunami on 11 March 2011. The affected reactors were adjacent to one another and accident management was made much more difficult because of ...
