Tepco now admits radioactive water entering the sea at Fukushima No. 1

Fisheries exec shocked by utility’s flip-flop on groundwater’s flow

Fukushima nuclear plant operator Tepco on Monday admitted for the first time that radioactive groundwater is flowing into the sea, fueling fears that marine life is being poisoned.
The admission came a day after voters handed the largely pro-nuclear Liberal Democratic Party of Prime Minister Shinzo Abe — and ally New Komeito — a handsome majority in the Upper House.
Earlier this month, Tokyo Electric Power Co. said groundwater samples taken at the battered plant showed that levels of cesium-134 had shot up more than 110 times in a few days.
Although unable to explain the increased readings, Tepco had nevertheless maintained the toxic groundwater was likely being contained, largely by concrete foundations and steel sheets.
“But now we believe that contaminated water has flowed out to the sea,” a Tepco spokesman said Monday.
However, the spokesman insisted the impact of the radioactive water on the ocean would be limited. “Seawater data have shown no abnormal rise in the levels of radioactivity.”
Tetsu Nozaki, chairman of Fukushima Prefectural Federation of Fisheries Co-operative Associations, voiced deep concern.
“It was quite shocking,” he told NHK. “(Tepco’s) explanation is totally different from the one in the past.”
Fishing around the Fukushima plant was halted shortly after the crisis, and production of beef, milk, mushrooms and vegetables was banned in surrounding areas, crippling the prefecture’s thriving fishing and agriculture industries.
Tepco, which is surviving thanks to a massive infusion of public funds, said it would step up efforts to reduce underground water by consolidating soil near its harbor.
Radioactive substances released by the reactor core meltdowns at the aging plant following the huge quake and tsunami of March 2011 have been leaking from damaged buildings and mingling with the ground water, which usually flows out to sea.
Environmental experts warn that the festering radioactive sore could contaminate the food chain by tainting marine life and ultimately, the humans who eat it.
Tepco said earlier this year that a fish found with radiation more than 2,500 times the legal limit had been caught in a port on Fukushima No. 1′s premises. It also said last week that around 2,000 people who worked at the plant now face a heightened risk of thyroid cancer.
This is 10 times more than Tepco’s previous estimate for potential thyroid cancer victims and came after the beleaguered utility was told its figures were too conservative.

Since the Fukushima accident, everyone understands the situation as h eperceives it to be and everyone is right, it is very serious indeed, but still we haven’t seen almost anything yet. And what we may risk to see and understand?

When sharing the galette des rois, some cookies are stuffed with a a small gold coin (a gold Napoleon). If a greedy one swallows it inadvertently, he will have to wait one to two days to recover it but his health will not be affected.

Imagine the coins gold plated and filled with actinides (highly toxic alpha radiotransmitters) such as:
They all weigh 6 grams, have a diameter of 21 mm and the same visual appearance.
A) gold plated Uranium 238
B)  gold plated Plutonium 239
C)  gold plated Plutonium 238
D)  gold plated Polonium 210

We will not see any difference in appearance and weight.
You swallow any of those and nothing happens, either immediately or later.

The the lethal dose threshold  of an inhaled monolithic dust is:
0.835gram for A
0.000 000 4 gram for B
0.000 000 001 6 gram for C
0.000 000 000 007 gram for D

This means that the lethal dose of these coins could destroy:
6 lives for A (Uranium 238, there is a lot)
13,475,000 lives for B, more than Paris Metropolis population (Plutonium 239,there is a lot)
3700000000 lives for C, more than half of mankind (Plutonium 238 is rare)
850 billion lives for D, 120 times the world’s population. (Polonium 210 is very rare)

Yet these coins A, B, C and D have not caused you any damage after being swallowed, not even long after. Because they were all covered with a tenth mm of gold , which prevented the huge flow of alpha particles to destroy even just a little of your digestive tract.

Conclusion:alpha emitters radionuclides must remain CONFINED.

Avoid that nuclear plants explode, even one, especially those using MOX,such as the ones which are many in France.

this, are you still willing to fight FOR nuclear power?

There’s such a release of 137Cs (1st Gen) around Daiichi we can reasonably assume that the corium is in contact with the sea 

Cesium soars in water under No. 1 plant
Tokyo Electric Power Co. on Tuesday reported a surge in radioactive cesium levels in groundwater in an observation well at its Fukushima No. 1 nuclear power plant.
This signals radioactive contamination is spreading under the disaster-stricken facility.
Water sampled from the well Monday contained 9,000 becquerels of cesium-134 per liter and 18,000 becquerels of cesium-137, both about 90 times the levels found Friday, Tepco said. The well is near the turbine building for reactor 2 and about 25 meters from the plant’s harbor.
“We still don’t know why the level of radiation surged, but we are continuing efforts to avert further expansion of contamination,” a Tepco spokesman stated.
Government guidelines permit cesium-134 at 60 becquerels per liter and -137 at 90 becquerels. Once ingested, the substances accumulate in muscle and bone and are believed to cause cancers.
The water collected Monday also contained 890,000 becquerels of substances that include strontium, which emits beta radiation, compared with 900,000 becquerels found in groundwater sampled from the well Friday.
Groundwater cesium levels in the well and other observation wells had remained low until recently. Readings were often below the minimum detectable levels.
Explaining the reason for the low contamination in groundwater, Tepco had said cesium can be easily absorbed by soil.
Following the latest findings, however, Tepco officials now say they do not know why the cesium levels have surged.
“Mud that has absorbed radioactive cesium may have got mixed with the water. We will measure the (contamination of the) water again,” a Tepco official told reporters at the Fukushima Prefectural Government office.
The official also said Tepco will determine if radioactive substances are seeping into the sea after studying its seawater survey.
The company also said groundwater collected Monday from a well located near the reactor 3 turbine building and about 23 meters from the port was found to have contained 1,700 becquerels of beta radiation-emitting substances per liter.
The reading was about 20 times the level detected Thursday and the highest for such substances in the well.
The new readings came two days after Tepco said tritium, a radioactive isotope of hydrogen used in glow-in-the-dark watches, was present at levels 10 times the permitted rate.
Tepco said in late June it had detected the highly toxic strontium-90, a byproduct of nuclear fission that can cause bone cancer if ingested, at levels 30 times the permitted rate.
The substances, which were released by the meltdowns of reactors at the plant in the aftermath of the huge tsunami of March 2011, were not absorbed by soil and have made their way into groundwater.
Subsoil water usually flows out to sea, meaning these two substances could normally make their way into the ocean, possibly affecting marine life and ultimately impacting humans who eat sea creatures.

Level of radioactive tritium rising in harbor at Fukushima plant


TEPCO. has seen a rise in the level of radioactive tritium in seawater within the harbor at the crippled Fukushima No. 1 nuclear power plant.
A sample collected Friday contained around 1,100 becquerels of tritium per liter, the highest level detected in seawater since the nuclear crisis at the plant started in March 2011, the utility said Monday.
An official of the Nuclear Regulation Authority said groundwater containing radioactive substances may be seeping into the harbor from the plant site and there is a need to carry out a careful investigation because the data collected so far are limited.
The sample with the highest tritium concentration was collected near a water intake on the east side of the reactor 1 turbine building. Its level was more than double that of a sample taken on June 10 in the same area.

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.

-Sample as of June 21: 1,100 Bq/L
-Sample as of June 10: 500 Bq/L (previously announced)

-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?
