Tokyo .- The National Nuclear Security Agency (NNSA) has confirmed on Wednesday that radioactive waste from the reactor core four of the Fukushima-1 has exceeded 100,000 times normal levels. For its part, TEPCO has acknowledged that the level of radioactivity of iodine 131, cesium 134 and 137 is higher than normal and several fuel rods are damaged.
This is because the water level of the fuel pools, which cool the rods used, is down temporarily and those fuel rods that have been damaged pollute and increase the radioactivity, as reported by Japanese news agency Kyodo . In addition, the NNSA has requested TEPCO to examine the strength of the nuclear reactors at the Fukushima-1 against possible earthquakes.
The top of the reactor four is destroyed due to hydrogen explosions and subsequent fires, as well as reactors one and three. "Seeing that aftershocks occur almost every day, we must consider what will happen to the buildings damaged by explosions" of hydrogen, said NNSA spokesman, Hidehiko Nishiyama.
Nishiyama added that the work of strengthening the structure of the reactor are complex due to high levels of radiation, so that "we must consider other ways" of performance. Excess radiation at 22 workers Vice Minister of Health, Labour and Welfare, Yoko Komiyama, has confirmed that 22 workers at the plant in Fukushima-1 have been exposed to excessive radiation.
The maximum figure of 198 has been detected milisievers, nearly twice the legal limit that requires urgent treatment. The ceiling has been set at 250 mSv in a recent due to the situation. Workers continue in its work of highly radioactive water withdrawal. TEPCO has already removed about 700 tons of toxic water "a capacitor" of reactors one and three, but plans to release about 60,000 tonnes, "will take several weeks." The origin of this toxic water, officials said Nipponese, is located in the reactor two fuel rods which have been partially melted polluting the water, which reduces the task of cooling the reactors.
Large amounts of water were discharged into the reactors by emergency personnel several weeks ago as an emergency measure to cool
