Two explosions occurred Monday at the Unit 3 nuclear power plant in Fukushima 1
The reactor has resisted, provided shortly after the owner of the nuclear power plant, Tokyo Electric Power (TEPCO). The possibility of radioactive leaks is "low," added the government.
In Vienna, the International Atomic Energy Agency has confirmed this information
These two new explosions were six wounded had been considered by the government.
On site, local authorities have advised people that are still in a 20 km radius around the nuclear plant to remain housebound. The people outside were invited to use a mask or a wet towel to protect their airways, and to cover up to avoid exposing their skin to the air.
Another nuclear plant in the region, Fukushima No. 2, also known cooling problems on four of its reactors and power company Tokyo Electric Power (TEPCO) has taken preventive measures.
Japanese Prime Minister, Naoto Kan, said Sunday that the country faced the "worst crisis for 65 years since the end of the Second World War" while ensuring that it was not a new Chernobyl .
The No. 1 reactor, which exploded Saturday should have been arrested
A similar explosion with radioactive leak took place Saturday on the No. 1 reactor of the plant built 40 years ago and located 250 km north of Tokyo. The roof and walls of the reactor collapsed and a thick white smoke escaped from the plant.
TEPCO had then begun an operation to relieve pressure on the reactor, the cooling system broke down after the earthquake and tsunami on Friday.
The reactor No. 1 was to be taken out of service last month after four decades of operation, but its operating license was then extended by ten years.
"Super fighters" were sent to the Fukushima nuclear power plant, said the spokesman for the Japanese government. "The most important thing is to cool the reactor core," said Bertrand Barré, scientific advisor to Areva.
IRSN speaks of "rejection very important" in the atmosphere
For the IRSN (Institute for Radiological Protection and Nuclear Safety), the value of 1 mSv / h is "a very important release in the environment."
IRSN, based in Paris, citing information provided by the Embassy of France in Tokyo, adding that "only a few measures are currently available." Twelve hours after the explosion, according to the Institute, "the dose rate would have been of 0.040 mSv / hr.
Saturday, the Japanese news agency Kyodo, quoting a security commission had already indicated that radioactivity levels 1,000 times higher than normal was detected in the control room of reactor No. 1 Fukushima I.
Regarding the Number 3 reactor in Fukushima No. 1, IRSN said that "new releases of radioactive products" took place in the environment due to a "depressurization of the containment (... ) after the start of the meltdown. "
For reactors 1,2,3,4 Fukushima No. 2 (DOE), "it seems that plants are currently without cooling systems," says the Institute.
Pumping seawater still insufficient
Tokyo Electric Power Company (TEPCO), which operates the plant as the most affected, has taken various steps to reduce the level of pressure in reactors 1 and 3, especially by dumping tons of seawater
However, pumping at sea is not yet sufficient to restore the level of cooling water reactors, has recognized the operator on the night of Sunday to Monday, according to media reports.
First consequence of these problems repeatedly: the electricity supply will be disrupted, "said the Prime Minister.
In addition, the state of emergency was declared in a second and a third central station has encountered difficulties on Sunday announced the International Atomic Energy Agency.
The worst nuclear accident in the history of Japan
This accident had been evaluated by the Atomic Safety Agency at 4 on a scale of 7. Level 4 describes "accidents involving no significant risk from the site," according to the International Atomic Energy Agency (IAEA). The term "anomaly" is used for level 1 and "incident" is used only for levels 2 and 3.
Level 4 is the worst so far experienced in Japan, said an official of the International Agency.
