Three days after the earthquake and tsunami in northeastern Japan, the authorities intensified the nuclear alert in central Fukushima, Tokai Onagawa and due to failures in the cooling system of its reactors. The Japanese Nuclear Safety Agency notified the International Atomic Energy Agency (IAEA) that its plants had failures in the cooling system, which maintains a nuclear alert for fear of further radioactive leak.
A reported failure on Saturday in Fukushima joined yesterday Breakdown Onagawa plant, which showed high levels of radioactivity, but later normalized and in the central Tokai, where the cooling system failed in a reactor. Tokyo Electric Power (TEPCO), the operator of Fukushima, reported the possible partial fusion of the nucleus of one of the reactors at the plant after a drop in water level covering the nuclear fuel.
He said the fuel rods could have been a partial melting due to overheating in the reactor number two by a cooling system failure, indicating that the situation is critical, according to Japanese news agency Kyodo. The company explained that there was a time when the bars were completely exposed to lower the water level that covered, when the pump that injected liquid to the reactor was stopped for lack of fuel.
In that situation there was an overheating leading to the possible meltdown, a process that can cause the release of large amounts of radioactivity. Water levels then recovered to cover the bars. Japanese government spokesman, Yukio Edan, said in a press conference and is being injected back into the sea water reactor.
NHK national television said, citing sources TEPCO, some radioactivity was detected place, although it is unclear levels. The earthquake of 9.0 magnitude on the Richter scale and subsequent tsunami in northeastern Japan, which has left at least five people dead and missing, caused serious problems for units 1, 2 and 3 of the plant in Fukushima, about 270 kilometers from Tokyo.
Cooling systems from three of the six reactors at Fukushima is damaged and as a result of the operations to stop the beginning of fusion, two explosions were recorded in the building of reactors 1 and 3, but they were not damaged. Despite the situation, the Nuclear Security Agency of Japan on Monday ruled out the possibility of a Chernobyl-type accident in Fukushima, according to the Ministry of National Strategy.
'There is no possibility at all, a Chernobyl, "said Koichiro Genba, reproducing the opinion of the Nuclear Security Agency. The agency said that after last Friday's earthquake paralyzed the activity of 11 of the 51 nuclear plants in the country, to assess the damage.
