Huge tanks shipped to Fukushima plant / One gets full within less than 2 days

    Following up this article.. Tepco to carry new contaminated water tanks directly from the factory by transport ships [URL]   Tepco started carrying 6 contaminated water tanks from the factory in Mitsubishi heavy industries in Hyogo to Fukushima plant. The contaminated water is increasing faster than Tepco builds the new tanks in the [...]

4,200,000,000Bq of β and 10,000,000 Bq of γ nuclides leaked from ALPS again / New technology never get into operation

Extremely high level of radiation leaked from multiple nuclide removing system ALPS (Advanced Liquid Processing System). This system has been continuously in the serious trouble since they started the hot test last Spring. However, Tepco doesn’t change their plan to try to purify 1,960 m3 / day of contaminated water from this Summer. ALPS is [...]

[Assumption overturned] Bypass water already exceeded the safety limit / Tepco “won’t stop pumping up”

Following up this article.. Tepco started pumping up the bypass water to discharge / Tritium density jumped up to 87% of desired safety level [URL]   The tritium density already exceeded their desired safety limit before even starting to discharge.   It was one of the 12 bypass wells. From the sample of 4/15/2014, Tepco [...]

Someone turned on 4 irrelevant pumps / 203t of 37,000,000,000 Bq/m3 contaminated water transferred to wrong place

203 m3 of highly contaminated water was transferred to the wrong plant buildings. Cs-134/137 density was 37,000,000,000 Bq/m3 in the wrongly transferred water.   The basement floors of reactor1~4 retain the coolant water and groundwater that increase by 400 m3 per day. Both of them are highly contaminated. Tepco pumps it up and reuse it [...]

1 m3 of contaminated water leaked again / “Did someone make a hole on the tank for malicious purpose again ?”

1m3 of contaminated water leaked from another contaminated water tank. Tepco announced the leakage has already been stopped because all the water has gone out.   It was a 1m3 plastic tank beside 1,000m3 class of tanks. It is not explained why the tank was left there. A sub-contract worker found the tank was empty [...]

“Like a garbage house” / Tepco’s spokesman “Storage cabinet is too messed to track the past samples”

Following up this article.. [Tepco's upward revision] “80 BILLION was actually 280 BILLION Bq/m3 in last summer’s leakage” [URL]   The storage cabinet of contaminated water samples is not properly managed, remains like a “garbage house”, Tepco’s spokesman talked on 4/11/2014.   Regarding 300 m3 leakage of contaminated water, Tepco revised the radioactive density from [...]

[Tepco's upward revision] “80 BILLION was actually 280 BILLION Bq/m3 in last summer’s leakage”

Following up this article.. Leaked all β of “300m3 leakage accident” was also underestimated / INES level might be increased [URL]   All β nuclide density was 280,000,000,000 Bq/m3 in the leaked tank water last summer. All β nuclide means the collective of the nuclides to include Strontium-90. Tepco announced the all β nuclide density [...]

[Video column] Fukushima Diary talks “Tepco washing off Plutonium to the Pacific, huge risk for the least effect”

Tepco plans to start discharging the bypass water to the Pacific from this coming June, but alpha nuclides including Plutonium-238/239/240 and Uranium-235/238 will not be tested nor filtered. It would decrease only 10~25% of the groundwater flowing to the plant buildings, but why do they have to take such a risk ? When they finish [...]

Tepco started pumping up the bypass water to discharge / Tritium density jumped up to 87% of desired safety level

↑ The groundwater bypass wells     ↑ The tanks to stock pumped water before discharging     Following up this article.. Tepco NOT to analyze Plutonium or Uranium in bypass water before discharging to the Pacific [URL]   Tepco started pumping up the groundwater from the bypass wells on 4/9/2014. They have already stocked [...]

Tepco plans to discharge pumped groundwater to the sea this coming June

Following up this article.. Fukushima fishery cooperative gave Tepco the approval to discharge bypassed groundwater to the sea [URL]   Tepco is already planning to discharge the pumped groundwater to the Pacific this coming June. On 4/4/2014, Tepco published the report about their plan to increase the contaminated water storage. In this report, they made [...]
