On June 6, 2013 fishermen were asking Tepco to scrap its plan to release No. 1 plant water into Pacific, Fishermen in Fukushima Prefecture have voiced opposition to Tokyo Electric Power Co.’s plan to release groundwater from its crippled nuclear power plant into the Pacific. Some expressed concern Friday about the harmful rumors that might be triggered by such a discharge of water from the Fukushima No. 1 plant, while others said they don’t trust the utility. Previous releases of radioactive water led to widespread contamination of the surrounding sea and a halt in local fishing activities.
The fishermen’s views were expressed at a meeting between the Soma Futaba fisheries cooperative and representatives of the utility and the Agency for Natural Resources and Energy, under the industry ministry. Tepco promised to check the groundwater before its release to ensure it is not radioactive, but the fishermen remained distrustful.(

On June 19, 2013 Tepco released the nuclides analysis result of radioactive materials in the reactor1 ~ 4 water intake.
Of course not telling us anything about any Strontium as the Sr-89/90 data of reactor1~4 water intake has been “under analysis” since 2012 However, they haven’t published the readings of Strontium-89 and Strontium-90. The oldest sampling date was 12/10/2012. It’s been over 6 months but the readings xere still “under analysis”.

On 6/19/2013, Tepco announced they measured 500,000,000 Bq/m3 of Tritium and 1,000,000 Bq/m3 of Sr-90 from the groundwater taken from the east side of reactor2 turbine building. The sample was taken on 5/24/2013.
The radiation level in seawater doesn’t decrease. In order to investigate it, Tepco drilled 3 observation holes on the east side of the reactor1~4 turbine buildings.
As a result, significantly high level of radioactive water Tritium and Strontium-90 were detected. Tepco hasn’t published Sr-90 readings after 5/31/2013 as it is again “under analysis”.
Tepco states it is due to the contaminated water leakage out to the screen pump room of reactor2, which happened on 4/2/2013. In order to investigate the spread of the contaminated water, Tepco drilled 4 more observation holes. Tepco is planning to improve the ground by injecting chemical grout and fill the voids of crushed stone layer foundation.

On June 21, 2013 Tepco released its Nuclide Analysis Results of Fish and Shellfish (In the Port of Fukushima Daiichi NPS)

On 6/22/2013, Tepco announced they measured 450,000,000 Bq/m3 of tritium from an observation hole beside Fukushima nuclear plant port. The sampling date was 6/14/2013.
It is assumed to be located on the east side of reactor2, where they have measured 500,000,000 Bq/m3 of Tritium since last December. The Tritium level is still significantly high.
The data of Strontium-90 is still under analysis as usual.
Strangely, they don’t analyze the samples for Tritium and Strontium-90 in the North side of reactor5 ~ 6 water outlet and the south water outlet of the plant. The reason is not announced.

On June 24, 2013 Tepco annonced us that “Tritium is travelling underground with groundwater”

Tepco found significantly high level of Tritium in groundwater and in seawater.
About 500,000,000 Bq/m3 of Tritium detected on the east side of reactor2, Tepco analyzed the cause and mechanism of how it is spreading as below.
When leakage from the reactor 2 water intake section occurred in April 2011, a part of leaked water permeated and spread into the north-side ground through the reactor 2 power cable conduit, and remains under the ground. 
While cesium has been absorbed onto the soil, tritium has been moved by groundwater.

They further annonced us that the Tritium level in seawater spiked over double within 2 weeks,
Having measured 500,000,000 Bq/m3 of Tritium from groundwater, Tepco conducted the tritium analysis of seawater of Fukushima nuclear plant port.
According to their press release on 6/24/2013, Tritium level increased to be over double within 2 weeks. It is assumed that Tritium is significantly leaking into the sea for some reason.
1) Sample : Seawater
Sampling location : North of water intake of reactor 1 ~ 4
6/21/2013 : 1,100,000 Bq/m3
6/10/2013 : 500,000 Bq/m3
2) Sample : Seawater
Sampling location : In front of the sea bank (cf, Fukushima plant tide embankment is still in the temporary state “EXIF of the picture is removed”
6/21/2013 : 910,000 Bq/m3
6/14/2013 : 600,000 Bq/m3
Tepco stating they are going to continue to analyze seawater, but it doesn’t stop the sea contamination anyway.

Finally on June 24, 2013 2013 via TEPCO Press Releases: “Tritium Density Result of Water Quality Survey inside the port of Fukushima Daiichi NPS”, where they admit Strontium presence...

We have conducted water quality survey of the Tritium density in the seawater inside the port, of which sample taken on June 21, since a high concentration of Tritium and Strontium have been detected at the observation hole at the east side of the Unit 1-4 Turbine Buildings. According to the results shown as below, a rising trend of Tritium was observed.
<North side of the Unit 1-4 intakes>
-Sample as of June 21: 1,100 Bq/L
-Sample as of June 10: 500 Bq/L (previously announced)
<Front of Unit 1/2 bank protection>
-Sample as of June 21: 910 Bq/L
-Sample as of June 14: 600 Bq/L (previously announced)

 We will take samples of the seawater and measure the concentration again.
There were no changes in the all beta concentration of the seawater. “

 According to the results shown as above, a rising trend of Tritium was observed.

-Sample as of June  

Finally Tepco is admitting increasing ongoing leaks to the sea. Tritium leaking into the port has increased between June 10 and June 24, the level near unit 1—4 has more than doubled, Tepco admitting that those levels have been existing since 2011 and that they are on the increase after some decrease.Strontium and all beta have elevated and existing since 20111, and are continuing to be high.These two elevated levels indicate ongoing leaking into the sea. These readings are outside the walls and blocking materials put in place at the intakes.Tepco claiming that the cesium in the water is low but that the beta emitters like strontium are significant, Tepco is not clarifying at what depth they tested the water to get these readings. Soils readings would be useful as well, as previously Tepco concreted the floor of the port though it did not decreased the water levels according to these new reports,

Meaning to say Tepco has been covering these facts way back since 2011, lying and lying, to finally realease this snake out of their corporated bag, how many more snakes are there in that bag?
