Japan: Efforts to inhibit the spent fuel of nuclear power plants


On Tuesday, the bid with the command of a nuclear power plant workers in Japan was devastated, but the cooling system to restore power to critical services back to the center location, the efforts of the spent fuel pool heat prevent renewed threat posed further leaks.


2 reactor storage pools Fukushima Power Station holds spent nuclear fuel rods, workers, the reactor with water dousing Forced to divert their attention was spewing steam late Tuesday. If unchecked, boiling off the water in the pool to expose the fuel rods may release large amounts of radiation in the air.

'We can not leave it alone, we may need to take care of it as soon as possible' is Hidehiko Nishiyama, Japan's nuclear safety Deputy Director of the Institute Ahn told reporters.
There is some damage to the reactor cooling water pumps and machinery, workers now that the power cable to all six reactors in place, repair work from the authorities need, he said.
Tuesday in Tokyo Electric Power owns the plant, its power, said the lights were not turned on in the No. 3 reactor, the cooling system only.

All of the reactor cooling system, November 3 Power was knocked out of the earthquake and tsunami in the day, has been restored to the first unit 5 and 6.
They are not working before the earthquake, like the other four nuclear reactors, has a pool of spent nuclear fuel rods. To restore full power of another major effort, To resume field operations in the central command center, which was under it will be to monitor the level of nuclear workers in hot water with ease.

Recovery efforts are forced to work off the aerial and speculation authorities have been hampered by the difficulty of measuring the measurement of critical data. Aim and fire, through the gap of housing, workers spent fuel pool water flows are also three fire hoses to them from overheating Wotsu Blown by a series of explosions rocked the reactor continued pumping the water into the furnace, the site last week.
In Vienna, International Atomic Energy Agency official, complained that no information from Japanese authorities.
'We are one unit Has not received verification information relating to some of the time of containment integrity, the official, Andrew Graham, said.
'We are so concerned about not knowing the exact state of' He is also a lack of data on the temperature of the pool holding spent nuclear fuel rods in the institutions of, 3, 4 reactor. Continued to emit radiation that is the official site of other agencies, a source said it was unknown.

Separately, the Kyodo news agency, IAEA , Reported that it has detected 1,600 times than normal radiation levels from the plant about 12 miles. The government has ordered to stay indoors and away for people to evacuate the 12-mile radius around the plant, they said 18-12 miles.

The crisis has raised a suspension of food supplies and local spread of pollution. The government has traces of radioactive elements is shipped from these areas, seeking a ban on the government, vegetables and development that are found in raw milk from farmers around the site Was.

Elevated levels of radioactive iodine and cesium government also has been detected in sea water has been tested in Fukushima Prefecture fish as a precaution, Yukio, the chief cabinet secretary, and from was.
Health and related professionals who are low and the government, causing a threat to human health Tta Shino Sako is not, however, has emphasized.
Also Tuesday, public broadcaster NHK, citing the Ministry of Government, radiation levels 400 times above the level of the Fukushima Plant 25 Reported that it had been detected in the soil of miles.

NHK reported that the Gunma University professor, was released by iodine-131 radiation levels, typically 47 announced that the cesium was found to be 137 times that found in the soil of Japan 430 Said that once the normal level.
Professor Keigo Endou, but there were immediate health risks, said the need to monitor radiation levels.

Nuclear crisis has also cast a shadow on the monumental task of providing assistance to Japan hundreds of thousands of refugees from the earthquake and tsunami. Remain in temporary shelters more than 237 000 people, NHK reported.
Red Cross, the 350-300 has been assigned to the medical team working in disaster zones People and spokesman, said Marcus Francis.
The organization is also planning its relief efforts are already under way to scale up efforts to help the rehabilitation and reconstruction, Mr. Marx said. 'Now, people will need a better health system, you need a hot shower every day,' he said.
The medical team, who are dealing with many cases of pneumonia, hypothermia and disease as well as Markus from swallowed contaminated water, and solid. The doctors and diabetes As pressure, the article deals with a relatively elderly population of Japanese connection.
Is a constant need for medical care, Mr. Marx said. 'Doctors in the field, The water in the desert, to explain the situation from the health care, he said.

The cold season has not been added to the daily struggle for shelter and relief. Local forecast as cold front moves into the region most in the northeast, to hover around the freezing of the tsunami stricken prefectures, Predicts that the temperature of one night a week.
On Tuesday, the government raised the official death toll of 9079, and 12 600 more are missing, a warning that the overlap between the figures may be the authorities.
The final death toll is 18, 000 Could be reached, the government said. The economy also has taken the abuse.

Honda, Toyota, because it is difficult to raise both parts, at least until this weekend, said he will suspend auto production in the country.
Oil was found that the fire is extinguished at oil refineries in Chiba, near Tokyo was furious after the earthquake in the end.
However, 220 000 - while the country is one of the largest facility Sun barrels will be out of commission.
