IAEA confirmed core damage reactors in Japan

In all three of the existing NPP units "Fukushima-1" in Japan there is damage to the reactor core, reports Reuters referring to IAEA chief Yukiya Amano.
He said that the situation is extremely serious, and planned for Thursday, March 17 visit to Japan. Earlier, the IAEA has announced plans to send a team to Japan to aid in emergency response to nuclear power plant "Fukushima-1".

Reactor core is the space where the controlled fission of uranium isotopes. Complete destruction of the core will lead to the release in the reactor radioactive elements.

Earlier it was reported that as a result of several explosions and fires damaged container was the second reactor. In the first and third reactor "Fukushima-1" was recorded partial meltdown of fuel, while the latter was supposed to complete meltdown.

Cause of accidents at nuclear power plants, "Fukushima-1" was the earthquake and the resulting tsunami. At the time of the disaster at the plant operated three reactors of the six, who were drowned in the normal mode. Procedure began cooling fuel rods, but the tsunami damaged the diesel generators, which is why the emergency services had to start cooling seawater. Maintain a constant water level was not possible, because of which the fuel rods began overheating.

The first explosion occurred at the nuclear power plant on March 12, followed by several more, also lit up a room in one of the units, storing spent fuel.

Emergency on "Fukushima-1" has led to several releases of radioactive substances. According to ITAR-TASS referring to the Central Office for Meteorology and Geodynamics Austria, comparative analyzes of radionuclides in Japan show a significant release of radiation, which, however, is not yet a threat to people.

In connection with the probability of radioactive contamination of the European Commission issued a recommendation that check received from Japan products and animal feed, according to Agence France-Presse.

The earthquake and tsunami, according to the latest reports police in Japan, killing 4,314 people. 8606 people are reported missing, another 2282 people received various injuries. Information about the victims of the accident at the nuclear power plant there, but it is known that one of the staff station recorded radiation damage.

U.S. expert: plant "Fukushima-1" threaten lethal doses of radiation

 
Head of the Commission for the U.S. Nuclear Regulatory Jacko Gregory believes that emergency personnel Japanese nuclear power plant "Fukushima-1" threaten lethal doses of radiation. He spoke in the House of Representatives of the U.S. Congress on the hearing to consider the situation in the nuclear power plant "Fukushima-1" and its possible consequences for the U.S. nuclear power industry.
"We believe that around the reactor core there are high levels of radiation — Jacko Gregory said, without specifying which of the several NPP" Fukushima-1 "he has in mind. — Employees of the emergency services will be extremely difficult to get close to the reactors. radiation dose they receive potentially be deadly for a very short period of time. "
According to ITAR-TASS, and the authoritative American expert agreed that he could not give a complete forecast of developments in the nuclear power plant "Fukushima-1", because it does not have all the necessary information. "Our information is very limited," — he said, without explaining with how these statements relate to the representations of the American side of what experts Barack Obama was in close contact with the Japanese authorities on the situation prevailing in the nuclear power plant " Fukushima-1 ".
