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 carryawayheat before encasing them.
Then it's pumped back in to carry more heataway from the plant's fuel rods, which continue producing energy long after the chain reaction at the heart of the units has been stopped.
Such aerosol-induced clouds, however, would have silver linings if they formed near a hurricane because the rising air that created them would carryawayheat that would otherwise be sucked in to fuel the storm.
