Today several years after announcing the wonderful concept of freezing the soil around the core-breached reactors at Fukushima, "officials" announce they are going to actually start freezing soil today. The point to which is - it turns out the natural groundwater in the area flows (underground) through serious contamination, and then both comes up into the broken cellars of the nuclear plant, and oh, incidentally, flows right out into the sea. (They know that, but the "official" announcement that contamination has been leaking into the sea constantly is probably 2 years away.)
Here is link and text; and my detailed prediction below it:
"TEPCO to start freezing wall at Fukushima plant
"The operator of the damaged Fukushima Daiichi nuclear power plant has gained approval from the regulator to start freezing soil around its reactors. Tokyo Electric Power Company, or TEPCO plans to create an ice wall that will reduce the amount of groundwater flowing into the 4 reactor buildings and thereby limit the buildup of radioactive water.
"The utility got the go-ahead on Wednesday from the Nuclear Regulation Authority, or NRA, to begin the underground freezing. It is expected to start the work as early as Thursday. The volume of contaminated water at the plant is increasing due to inflowing groundwater.
"Once the freezing process is complete, together with other measures, the daily accumulation of underground water is expected to fall from 400 tons to about 50 tons. The wall is expected to start restricting the inflow of groundwater about 45 days after the freezing starts.
"TEPCO finished building the underground freezing systems last month, after 2 years of work.
"But the regulator did not immediately give the greenlight to its freezing plans. It was concerned the wall could lower the groundwater level too much and cause radioactive water pooled in the reactor buildings to leak out.
"TEPCO submitted a revised plan to do the freezing work in stages. Under the new plan, it will first freeze soil at the downstream side of the buildings to prevent water leaking there.
"NRA Chairman Shunichi Tanaka said the operation will be a major challenge. He said it is important to carefully monitor the freezing process with adequate data."
My prediction; based not on rancor or ill wishes but on Physics, Chemistry, and Hydrology: the ice wall will not work. Will never work, can not ever be made to work, and is quite likely to cause new and possibly worse problems with contaminated water at the site.
"Why" it won't work requires long discussion, which perhaps we will do after it is announced that it isn't working; my guess will that announcement will happen within the next two months. Hard to cover up 200 tons of new water every day.
So why did they build it, if common science says it can't work? Several reasons, none good- A) they don't know how to do anything that might be effective, B) They have to appear to be doing something, and C) There is a huge amount of money to be made, from public funds, building something so wacky. When it fails, they'll just wring their hands and walk away- the executives with fat bank accounts, and the public reputation of saints struggling with evil.
