2nd try at sealing Japan nuke leak not working yet


2nd try at sealing Japan nuke leak not working yet:  It could take several more months to bring Japan's tsunami-ravaged nuclear plant under control, a safety agency spokesman said Sunday as engineers tried to find a way to stop highly radioactive water from pouring into the Pacific.

Fukushima Dai-ichi Nuclear Power Plant is spewing radioactivity after March 11 tsunami carved a path of destruction along the coast of northern Japan, killing 25,000 people. The final death toll is unknown because many are still missing.

Nuclear Air Safety spokesman Hidehiko Nishiyama Sunday was the first in mind, how long it may take to end the nuclear crisis, which forced people to 12 miles (20 km) at the factory to leave their homes because of radiation.

"It would take a few months until we finally have things in hand and have a better idea of ​​the future," Nishiyama said. "We face a crucial turning point in the coming months, but this is not the end."

Bring the reactors under the control necessary to restore a permanent cooling systems to prevent the tsunami eliminated the reactor dangerously overheating. This task has been complicated by dangerous conditions in the plant that is often forced workers to stop what they're doing.

Some new problem crops up complex almost daily. Workers found an 8-inch (20 cm) crack in a septic maintenance on Saturday and said they believed that water may be the source of some of the high levels of radioactive iodine were found in the sea for over a week.

They found it difficult to tell where the water comes from and is the first time they found a leak into the sea A photo released by the plant operator Tokyo Electric Power Co. shows the water shooting from a distance of a wall and splash into the sea, if the amount is not clear.

Contaminated water is quickly dissipated in the ocean, but could pose a hazard to workers at the plant.

Engineers were trying to seal the cracks with concrete on Saturday, but it did not work. Then on Sunday they have injected a mixture of sawdust, shredded newspaper and a polymer that can be extended to 50 times its normal size when combined with water. The polymer blend had not stopped the leak Sunday night, but engineers have not given up hope, and they should know by Monday morning if it will work.

TEPCO on Sunday confirmed his death before the tsunami in the factory itself, "said the 21-year-old and 24 years, were conducting a routine inspection of the 9.0-magnitude earthquake that preceded the disaster.

Apparently ran into the basement of the turbine hall, which is where they were swept in the massive plant.

"This troubled us have lost those two young men who were trying to protect the power station in the middle of an earthquake and tsunami," TEPCO president Tsunehisa Katsumi said in a statement.

High levels of radioactivity in the factory of the search for dangerous men. Their bodies were not discovered until Wednesday and had to be cleaned. The notification was delayed when the authorities announced their families, Kazufumi Suzuki TEPCO spokesman said.

The nuclear crisis has aggravated the suffering of people in the Northeast and, sometimes, the shadow of his fate. Tens of thousands of people lost their homes and live in shelters, 200,000 households have no water, and 170,000 have no electricity.

Running water was restored in the port city of Kesennuma Saturday, and residents lined up Sunday to see a dentist who had flown in from the north to offer his services. Many were older and complained of problems with their prostheses.

Overhead and the entire coastal region, meanwhile, helicopters and planes screamed by the Japanese and U.S. forces have completed their search for bodies in all directions.

The work, which ends Sunday, is probably the last hope of recovering the dead, although limited operations can be resumed. It has proven to be nearly 50 bodies in the last two days.

In all, more than 12,000 deaths have been confirmed, and another 15,500 people are missing.
