Emergency situation around the nuclear power plant "Fukushima-1" in Japan over the past day has not demonstrated a certain dynamics. The whole world is still frozen in anticipation of the worst, comments of experts from Europe and the U.S. are much more pessimistic and gloomy than the ones that give the IAEA and the Japanese government.
The latest data and pictures from the scene of the accident: over the reactor number two columns of white smoke rises. The representative of the Agency for Nuclear Safety Japan Hidehiko Nishiyama said the smoke could be caused by overheating of spent nuclear fuel at the reactor, "Interfax".
At the same time, the plant operator TEPCO said: fifth and sixth power units, which until recently were considered relatively successful, could increase to dangerous levels of fluid temperature in the storage of spent nuclear fuel (SNF). As RIA "News", the temperature can rise to dangerous levels, it is possible repeat of the situation in the first and fourth blocks, where, after the devastating earthquake there are explosions and raging fires.
Previously, the agency Kyodo reported that the temperature in the storage of spent nuclear fuel at the six reactors had risen to 64 degrees Celsius. A company representative said that the cooling system stores the fifth and sixth units are connected to each other — in this context, there is a risk of heating the two repositories.
One of the Assistant Directors-General of the International Atomic Energy Agency (IAEA), Graham Andrews made late Thursday following statement: background radiation in the 30-kilometer zone around the Japanese nuclear power plant emergency, "Fukushima-1" "increased significantly" increased levels of radiation in some places there time. However, he said, in Tokyo increased radioactivity was observed.
In general, he said, the situation at the plant "Fukushima-1" "remains very serious, if not worse." The biggest concern is the fourth unit, the status of which is still almost no reliable information. "The water temperature at the fifth and sixth units was reduced, — he said. — The situation in the first three power stabilized. Cooling system is not working for them, so the reactors are cooled by water from the water cannon and sea water, which dropped from a helicopter."
At the same time of the Japanese media the impression that the desperate efforts of Japanese experts to cool the reactor until a particular failed. Thus, the NHK TV channel reported that the Japanese government and did not decide to go on a Friday operation to fill with water from the third power plant emergency vehicles, equipped with powerful hoses. This operation creates a risk to the health of staff to high levels of radiation close to the object.
The operation to fill the earth with the third unit started on Thursday at 19:35 local time (13:35 GMT) and was completed at 20:00 local time (14:00 GMT). As reported, five emergency vehicles, equipped with powerful cannons, stopped 10 meters from the unit and started pouring.
According to police, supplied from the water hoses did not reach his goal, and the high level of radiation, marked the third unit, did not allow an expert to come to a close distance.
However, work on the filling of the third block on Thursday carried out not only from the ground but from the air. The operation involved helicopters were self-defense forces of Japan. But this led to a strange result: soon after pouring from the helicopters in the third unit was recorded an increase of background radiation. Radiation levels rose to 4 thousand microsieverts per hour with 3.7 thousand microsieverts per hour. Up to now none of the experts explain what it might be related.
However, later broadcaster NHK citing Petersen said that radiation levels at the nuclear power plant emergency, "Fukushima-1" after the water cooling the third unit is still down slightly. According to the operator, measurements of radiation levels made on Thursday at 20:40 local time on the western gate of the station, it showed a decline of 20 points to 292 microsieverts per hour. After 2 hours, the rate went down by 3 points.
Evacuation of Russians continues
Petropavlovsk-Kamchatsky in Tokyo today flew the plane EMERCOM IL-62 for the evacuation of Russian citizens from the disaster zone. Itar-Tass reported in the press service of the main emergency department in the Kamchatka region. Ship can carry 162 passengers. Of Tokyo, he will deliver them to Khabarovsk.
Obama said that Fukushima is a real threat
Japanese nuclear power plant "Fukushima-1" in respect of damage to property is now is a "significant risk to nearby people." This was announced today at the White House, U.S. President Barack Obama. However, he said, the U.S. government experts "do not expect harmful levels of radiation" from the NPP "Fukushima-1" can reach the West Coast of the U.S., "Hawaii, Alaska or U.S. territories in the Pacific.
