tokyo electric uses sawdust to stop radiation leaking into sea  -  biodegradable absorbent material
Tokyo Electric Power Company
Using a mixture of polymer, sawdust, and newsprint, try to prevent radioactive water from infiltrating the damaged Fukushima nuclear power plant into the sea.
The absorbing material is injected into power-
The electric power company said at a briefing in Tokyo today that the cable storage pit is where sewage leaks through cracks.
It will introduce a tracker into the pit to check if the operation is successful.
Since the March 11 earthquake and tsunami destroyed the cooling system of the nuclear power plant, Tokyo Electric Power has been working to prevent radiation leakage and plans to start injecting nitrogen into the reactor today to reduce the threat of hydrogen explosions, and connect the power cable to the pump. “The water-
In this case, the absorbent polymer has never been used before, so I'm not sure if this works, "said Suh Kune Yull, professor of nuclear energy systems engineering at Seoul National University.
"It may not be easy because the leaking pit is wide.
"Radiation from contaminated waters near Fukushima
Tepco said in a statement yesterday that the Ichi plant is measuring more than 1,000 millisieverts per hour.
According to the United States, exposure to this level can cause nausea for an hour, and four hours can lead to death within two months. S.
Environmental Protection Bureau.
"Radiation levels may not affect the sea and fish that are moving, but if Japan can't stop the leak quickly, it's enough to pollute seaweed and clams near the nuclear power plant, suh said by phone in Seoul.
Tokyo Electric Power said the bodies of two workers who had disappeared since the March 11 earthquake were found today.
They have been doing repairs in basement one.
The company said at a news conference on the Internet today that the plant's reactors.
The latest death toll has brought the death toll of workers at two nuclear power plants in Fukushima to seven, including five employees of sub-sub.
The contractor who confirmed the death on 14 and March 12.
As of the 10 th, the total number of deaths and missing in Japan's disaster was 27,481. m.
Tokyo time today
Goshi Hosono, a Democratic Party member of the ruling coalition, told reporters that it could take several months to stop emissions of radioactive substances.
Hosono is the special envoy of the government and Tepco.
A company executive said earlier today that he was not optimistic about the prospect of containing the Fukushima disaster.
Number of the first nuclear power plant. 3 reactor.
"I don't know if we can get into No.
The reactor was built again, "Kuroda, head of nuclear facilities management at the company, said at a news conference.
Japan's Nuclear and Industrial Safety Agency yesterday ordered TEPCO to strengthen monitoring of seawater near the No. 1 nuclear power plant.
Xishan Yingyan, deputy director of the agency, said the leak caused two reactors after radiation rose. Above-
Normal levels of radioactive iodine were detected in 40 kilometers of seawater (25 miles)
The plant is located in the South, nhk TV reported.
About 10 centimeters (4 inches)
Radioactive water was found in the leaking pit to 20 centimeters, which was 1. 2 meters by 1.
Company spokesman Takashi Kurita told reporters at a briefing at the headquarters of Tokyo Electric Power Company that 9 m and 2 m deep, about 20 centimeters wide.
Tokyo Electric Power Co. is trying to fill cracks in a pit near reactor one.
Junichi Matsumoto, another company official, said at a subsequent press conference yesterday what was the specific situation.
Water in the pit was found to contain 10,000 times more toxic iodine 131 than normal levels, he said.
Kyodo reported the leak first yesterday.
Su Sumu Suzuki, a maintenance official at Tokyo Electric Power nuclear facilities, told reporters that the pit was separate from the trench where the company earlier found contaminated water.

Chief Executive Jeff Immelt of Tepco will meet with officials of Tepco. S. company.
GE spokesman Deirdre Latour said in an email that Immelt was traveling to Japan to "meet with employees, partners and customers, including TEPCO"mail.
The reactor in the damaged factory is based on fourdecade-
Old design from Fairfield, Connecticutbased GE.
Tsunoda said TEPCO plans to start injecting nitrogen into the plant today, but does not specify where it is.
After the March 11 tsunami destroyed the reactor cooling system, the overheated reactor released hydrogen and exploded several times. A 9-
The Richter earthquake and tsunami occurred at the Fukushima nuclear power plant about 220 kilometers, and the power was interrupted and the reactor was damaged (136 miles)north of Tokyo.
In the worst nuclear accident since the Chernobyl accident in 1986, workers have been spraying water to cool radioactive fuel rods at reactors.
TEPCO says it is connecting power cables to a cooling system in three of the four damaged reactors.
Connecting the power supply may not work because the explosion ripped the factory a few days after the earthquake and could cause damage.
Japanese Prime Minister Naoto Kan visited the earthquake and tsunami area for the second time yesterday, according to Japanese Prime Minister's website.
Naoto Kan took a helicopter to Iwate county in the northeast, met with the evacuees, and then went to the neighboring Fukushima prefecture to talk to himself.
