Japanese Experts: Effort is in danger of failing… and reactors too hot to cover in concrete — TEPCO admits there is no end in sight

Improvisation, frustration mark Japan’s nuclear crisis at 4 weeks, CNN, April 10, 2011:

… 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. Tetsunari Iida, an engineer-turned-industry critic, said the situation is “beyond the reach” of Japan’s closely knit nuclear establishment. …

[E]xperts say the overheated fuel rods are likely to have suffered extensive damage, and there is a complication for seemingly every advance. …

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. “They must change the approach. That’s something I’m sure of 100 percent.”

After the 1986 Chernobyl accident, the world’s worst to date, the Soviet Union encased the plant’s damaged reactor in a massive concrete sarcophagus. Iida 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. …
