After the devastating earthquake and tsunami, the situation in the nuclear power plants in the country has worsened dramatically over the weekend. In multiple reactors, the cooling systems failed. Whether a meltdown (Japan: Horror-meltdown scenario) has been used was still unclear on Sunday. Around 160 people were potentially contaminated.
Overheated fuel worrying is the largest nuclear power plants - particularly the complex Fukushima, who has two facilities with a total of ten reactors. In Unit 1 of Fukushima-Daiichi , it came on Saturday to a detonating gas explosion, after the authorities had initiated sea water to cool down the overheated fuel rods, thus preventing a potentially fatal meltdown.
On Sunday, said government spokesman Yukio Edano, a similar explosion threatened in Block 3 of the plant. That in both reactors sea water was introduced, experts considered a sign that the authorities have given up the reactors and it only comes to prevent a meltdown at any cost. Also, a few kilometers away Fukushima-Daini nuclear power plant, there were three reactors problems with the cooling systems.
According to the International Atomic Energy Agency also reported the nuclear power plant Onagawa nuclear alert the lowest level, as is required at elevated radiation levels in the immediate area. According to the authorities, the three blocks of the system under control. Also in the Tokai nuclear power plant about 120 kilometers north-northeast of Tokyo, there were problems with the cooling.
As the operator Japan Atomic Power Company announced only on Sunday, one of the two pumps was made during the earthquake on Friday. The other pump continue to work, however, the reactor during normal and there was no risk of radiation departed. In Fukushima, the radiation exceeded at times the permissible limits.
The burden is now, however, so low that there is no danger to the health of people. According to the Japan Atomic Energy Agency were up to 160 people may be exposed to radiation and were taken to hospitals. More than 170,000 people were evacuated within a radius of 20 kilometers around the power plant now.
