Fukushima updates - July 13 , 2013 ...... Fukushima = Tepco-nado ? Enough said.....


Former Fukushima worker “Stopping groundwater flowing to the sea may cause various problems”

High level of radiation is measured from groundwater and seawater.
Tepco suspects there is a “possibility” that the contaminated groundwater is flowing to the sea, they are building the underground wall to stop it moving to the sea.
(cf, Tepco doesn’t estimate how much more groundwater would flow into the plant by stopping it flowing to the sea [URL])
However  about this construction, the former Fukushima worker Happy11311 commented on Twitter that it may cause unpredictable problems in the plant.

Tepco can’t decrease the groundwater volume to flow into the plant because they can’t get the groundwater bypass into operation without the approval of Fukushima Prefectual Federation of Fishries Co-operative Associations. Also it takes long to build the impervious wall in the mountain side.
If they stop groundwater flowing to the sea before stopping it from flowing from the mountain to the plant, the increasing retained groundwater may cause various problems. It has the highest priority to stop sea contamination for sure but..

Tepco doesn’t estimate how much more groundwater would flow into the plant by stopping it flowing to the sea

Having measured high level of radioactive material from groundwater and seawater, Tepco is planning to build underground wall beside the seaside.
(cf, Tepco to “improve” the ground to stop groundwater contamination spreading by crushing an observation hole [URL])
At this moment, it is estimated 450 tones of groundwater flows to the sea everyday.
(cf, Former Fukushima worker “450 tones of groundwater flows to the sea everyday” [URL 2])
If they stop it from flowing to the sea by the underground wall, the same volume of groundwater would possible come back to the plant.
Now 400 tones of groundwater flows to the basement of the plant. If this additional 450 tones of groundwater flows into the basement of the plant, it would overwhelm the water purifying capacity and storage capacity. Also, the increased water pressure may damage the bottom and the wall of the buildings.
(cf, Former Fukushima worker, “Groundwater stopped by underground wall may reverse to damage the reactor buildings” [URL 3])
In the press conference of 7/12/2013, Tepco stated they don’t have the estimate of how much more groundwater would flow into the basement of the plant. 
They commented though they don’t know the potential effect to the plant, stopping groundwater from flowing to the sea has the higher priority.

                                      Should we refer to Japan as Tepco- nado ?  After all , japanese nuclear     policy is like a really bad Sci Fi movie Too ! Radiation contamination whirling  through the sky with Tepco personnel fubaring away in the midst.........
