A month into the crisis, the utility acknowledges, there is no end in sight.
Some Japanese experts now say the effort is in danger of failing unless Japan seeks more help from international experts to bring it to an end.
Tokyo Electric officials told CNN they can't say when they'll be able to restore those normal cooling.
Satoshi Sato, a Japanese nuclear industry consultant, called the current line of attack a "waste of effort." Plant instruments are likely damaged and unreliable because of the intense heat that was generated, and pumping more water into the reactors is only making the contamination problem worse, he said. "There is no happy end with their approach," Sato told CNN.
[Tetsunari Iida, an engineer-turned-industry critic] said Fukushima Daiichi's reactors remain too hot to pour concrete, but he suggested pouring a slurry of minerals and sand over them to carry away heat before encasing them.
