Groundwater level rising at 800m from the coastal line

The groundwater level is also rising in the mountain side of Fukushima plant, according to Tepco. It’s approx. 800m from the coastal line, where a underground reservoir is located.
From 11/29 to 12/1/2013, all β nuclide density increased from 8,600,000 Bq/m3 to 20,000,000 Bq/m3 in the leakage detector hole water of the reservoir, which made Tepco realize the rising groundwater level. Tepco is attempting to stop the reservoir from floating.
Because of the underground wall on the coastal line, groundwater level is increasing in various places near the sea. However, Tepco hasn’t officially admitted the groundwater level is also rising even in the mountain side of the plant area widely, and it can be due to the underground wall, which can be the only cause.
The rising groundwater level also increases the atmospheric dose of seaside. (cf, Fukushima plant radiation increasing due to the rising contaminated groundwater / “Covering with lead plate” [URL 2])
This October, Fukushima plant area even experienced the major land subsidence. It was supposed to be solely because of a typhoon.

7,500,000 Bq/m3 of “Strontium-90″ detected from groundwater near reactor1

7,500,000 Bq/m3 of “Strontium-90″ was measured from groundwater. The sampling date was 9/11/2013. They haven’t announced it for 3 months.
The location is in the seaside of reactor1. Tepco has been analyzing the groundwater around the reactor buildings.
This November, Tepco confirmed reactor1 directly leaking the coolant water out of the vessel.
(cf, Leaking part of reactor1 is made of “poly vinyl chloride” [URL])

All β nuclide density in groundwater beside reactor3 marked the highest for 2 continuous days

The highest density of all β nuclide (including Strontium-90) was measured in groundwater for 2 continuous days. The location is between reactor2 and 3.
The underground wall is raising the groundwater level. Tepco is pumping up the rising groundwater, which is the tested sample.
On 12/5/2013, all β nuclide density was 170,000,000 Bq/m3. The next day, it reached 180,000,000 Bq/m3.
There is no announcement of Tepco about the increasing density.
Groundwater level of more area starting to be in sync with ebb and flow of the sea

Following up this article.. [Impervious wall broken ?] Groundwater level near the plant building in sync with ebb and flow of the sea [URL]
The groundwater level is found in sync in another place. The location is the seaside of between reactor3 and 4. The underground wall to isolate the area from sea is completed almost 36%.
The connection between the ebb and flow of the sea and the groundwater level were not seen through this November, but it’s started being clear since 12/3/2013. There was no significant volume of rainfall before then.
There is a possibility that the groundwater is being directly connected to the sea.
Tepco “Attached a dosimeter on the top of a
pole, moved it by a minitruck to measure 25
Sv/h”

Following up this article.. 25 Sv/h from the damaged stack for reactor1 and 2 / Highest reading outside of the buildings [URL]
Because the ambient dose is too high for a worker to survey near the bottom of the stack, Tepco measured it by a dosimeter attached on the top of a pole.
The pole was fixed on a minitruck. By moving the minitruck, they tested the radiation dose of various points.
They assumed there is a part of 25 Sv/h on the stack, but they couldn’t measure it directly.
The moderate technology level implies the various challenges Tepco may encounter through the process of decommission Fukushima plant.
25 Sv/h from the damaged stack for reactor1 and 2 / Highest reading outside of the buildings

There is the possibility that the radiation dose is 25 Sv/h near the bottom of the stack, according to Tepco. Tepco states highly radioactive particles might be attached on the part.
From 11/21 to 11/22/2013, Tepco measured radiation levels near the bottom of the stack.
They detected the atmospheric dose of 95 mSv/h near the part where they measured 10 Sv/h in August of 2011.
Based on the collected data, Tepco assumed there is a radiation source of 25 Sv/h at 1.5 m from the point of 95 mSv/h.
In the press conference of 12/6/2013, Tepco’s spokesman commented they don’t think molten fuel attached to the part is causing the high level of radiation.

Japan Govt. Declared Evacuation Too Expensive, IAEA Promotes More Sea Dumping
A government trip to research how the response to the Chernobyl disaster was conducted but the report was never made public. The officials looked at what was done after Chernobyl and declared it to be too expensive and complicated for the Japanese government so they suggested it be ignored. They declared there was little benefit to evacuating people but it was admitted the report ignored more critical evidence of the actual damage done to the … Read entire article »
Testing On Frozen Wall At Fukushima Daiichi Is Underway
Work has begun to test the frozen underground wall concept at Fukushima Daiichi. A test section was frozen including the area inside pipes in the mock up. A video of the work can be found here http://youtu.be/4se7KSjF1lY TEPCO hopes to install the wall with government help and funding in upcoming years to combat the constant flow of contaminated water to the sea.

Panel Urges New Water Responses At Fukushima Daiichi
One of the various panels making suggestions for the response to the mess at Fukushima Daiichi has called for 5 new measures to combat radioactive water at the plant. As the plant continues to leak an estimated 9 terabecquerels of just cesium 137 alone to the sea every month, these solutions are critical. Storage tanks with double outer walls Sealing cracks and … Read entire article »
