On the Fukushima-1 started to be realized the worst case scenario

The Government of Japan announced a partial meltdown of fuel rods in a second reactor nuclear power plant damaged by an earthquake.
In the second reactor damaged by an earthquake Japanese plant "Fukushima-1" was a partial meltdown of fuel rods, which caused increasing levels of radiation in the water used to cool the reactor, said on Monday the representative of the Japanese government. Earlier, the Russian nuclear scientists said that the melting reactor cores is the worst, but not a fatal case scenario in Japan.

"The radiation seems to have got out of the fuel rods that partially melted down and came into contact with water used to cool the reactor," — said at a press conference the Secretary General of the Japanese Cabinet Yukio Edano. "Steam may have condensed … moving water on the shielding of the reactor."

According to him, the Japanese government has no information about how long did the process. "The presence of radiation in the air, mainly constrained by the reactor vessel. We must make sure that the water does not seep into the ground and not get into the sea, "- he added. (Quoted by Reuters).

A member of the operational headquarters of "Rosatom" Jaroslav Shtrombah said earlier that the melting reactor cores plant "Fukushima-1" is the worst case scenario, but in this case, most of the radioactive nuclear fuel remain inside buildings and units will be scattered throughout Japan. Will I have to in this case to build the shelter like a sarcophagus at Chernobyl or be able to collect and dispose of the fuel, while we can not say exactly, told "Vedomosti" a source in the "Rosatom".

Nuclear crisis on the "Fukushima-1" began on 11 March, after a devastating magnitude 9.0 earthquake and the resulting tsunami, a blow which killed or went missing nearly 26 000 people, and the country suffered a loss of about $ 300 billion after the earthquake NPP was recorded a series of accidents caused by the failure of the cooling system. The result has been several leaks of radiation, forcing authorities to evacuate people from the 20-kilometer zone around the plant, as well as a ban on flights over the station within 30 miles.

Two of the six reactors of the plant at this time are considered safe because they were stopped cold. The situation in the other four reactors remains unstable — on them periodically rising smoke and steam, and engineers are trying to restart a failed after the disaster cooling system.

In recent days, radiation levels at the plant "Fukushima-1" has jumped on Sunday, the radiation in the water exceeded the norm of the second reactor of 100 000 times. And the first experts who carried out the measurements, mistakenly reported that the level of radioactive iodine in the water on the second reactor exceeds the norm of 10 million times. However, the level of radiation in seawater near the plant, exceeded the permissible level before the time in 1850, declined sharply, said on Monday the deputy director of the Agency for Nuclear and Industrial Safety Japan Hidehiko Nishiyama.

According to Reuters, the radiation particles with damaged plant have reached Iceland, although Japan insists that the number is not dangerous to adults, and higher doses of radiation received only emergency services personnel working on the "Fukushima-1". Meanwhile, last week, the residents of the capital Tokyo advised not to give tap water to children under one year, as the level of radioactive contamination doubled the allowable value for nursing babies. But just a day indicator, allegedly by Japanese authorities, returned to normal, and the mayor of the city in front of TV cameras drank tap water in one of the treatment plants of the city.

Then referring to the Kyodo Tokyo authorities reported on exceeding standards for levels of radioactive cesium in vegetables grown in the capital by 1.8 times. Exceeding normal levels of radiation were also found in vegetables and milk from Fukushima prefecture itself. The importation of products from a number of Japanese prefectures have already given Australia, USA, Hong Kong and Singapore.
