Plan to build ice wall around Fukushima plant hits snag


[snip]

TOKYO —
The operator of Japan’s battered Fukushima nuclear power plant said Tuesday it was having trouble with the early stages of an ice wall being built under broken reactors to contain radioactive water.
Tokyo Electric Power Co (TEPCO) has begun digging the trenches for a huge network of pipes pipes under the plant through which it intends to pass refrigerant.
This will freeze the soil and form a physical barrier that is intended to prevent clean groundwater flowing down mountainsides from mixing with contaminated water underneath the leaking reactors.
TEPCO said Tuesday a smaller, inner ice wall whose pipes it sank earlier to contain the already-contaminated water was proving difficult.
“We have yet to form the ice stopper because we can’t make the temperature low enough to freeze water,” a TEPCO spokesman said.

Full decommissioning of the plant at Fukushima is expected to take several decades. An area around the plant remains out of bounds, and experts warn that some settlements may have to be abandoned because of high levels of radiation.

Has any one told these "Experts" you can't freeze water around 3 Molten Laval Coriums?
