It is probably the first time in the industry's 57-year history that

seawater has been used in  bakugan toys   this way, a sign of how close Japan is to

facing a major nuclear disaster following the massive earthquake and

tsunami on Friday, according to the scientists.

 

Tokyo Electric Power (TEPCO) workers on Sunday were pouring seawater

into two reactor cores at the　 power balance  coastal Fukushima Daiichi power plant and

were considering using seawater on a third. Authorities have been

forced to vent radioactive steam into the air to relieve pressure in

the plant and reactors at the company's nearby Daini plant are also

troubled.

 

"I am not aware of anyone using seawater to cool a reactor core before.

They must be desperate to find　 power balance  water and the seawater was the only

thing nearby," said Richard Meserve, former chairman of the U.S.

Nuclear Regulatory Commission and president of the Carnegie

Institution, in an interview on Sunday.

 

He said that suggests the company has decided it will sacrifice the

reactors altogether, in what has become the worst nuclear accident

since the Chernobyl disaster in Ukraine in 1986.

 

The method being used to regain a semblance of control of the reactors

smacks of last-resort desperation, said Robert Alvarez of the Institute

for Policy Studies and formerly a senior policy adviser at the U.S.

Department of Energy.

 

"I would describe this measure　 power balance  as a Hail Mary Pass but if they succeed,

there is plenty of water in the ocean and if they have the capability

to pump this water in the necessary volume and at the necessary

rates...then they can stabilize the reactor," said Alvarez in a press

conference on Saturday.

 

In a sign of how volatile the situation is, the Union of Concerned

Scientists said in a statement on Sunday in Washington that it fears

the situation "took a turn for the worse as serious problems developed"

at the Unit 3 reactor at Daiichi.

 

It said that statements from Tokyo Electric officials indicate that

water levels have dropped so far that approximately 90 percent of the

fuel rods in the core of the reactor were uncovered and that despite

pumping in seawater the water level is still well below where it should

be.

 

The Daiichi plant was shut immediately after the March 11 earthquake

when outside power was lost. Diesel generators kept the cooling water

running over the superheated uranium 　 power balance  fuel rods in the reactor core for

about an hour until water from the tsunami caused them to stop.
