FUKUSHIMA – Tepco on Monday discharged into the ocean filtered groundwater taken from wells around the damaged reactor buildings at the Fukushima No. 1 nuclear plant in an effort to curb the buildup of toxic water.

The project has been touted as one of Tokyo Electric Power Co.’s key measures in tackling the contaminated water problem.

Some 300 tons of untainted groundwater seeps into the buildings each day, where it mixes with water made radioactive by keeping the damaged reactors cool.

By pumping up groundwater through 41 wells and discharging it into the sea after treatment, the government and Tokyo Electric Power Co. hope to halve the amount flowing into the reactor buildings.

On Monday, Tepco released some 850 tons of filtered groundwater — part of some 4,000 tons pumped up last year on a trial basis and stored in tanks — after confirming that radiation levels were below measurable limits.

Tritium, which cannot be removed with existing technology, measured 330 to 600 becquerels per liter, well below the legally allowable limit of 1,500 becquerels, the utility said, citing analyses conducted by the company and an outside organization.

Fishermen in Fukushima Prefecture had long opposed releasing the water over concerns it would pollute the ocean and contaminate marine life, but signed off on the plan in August.

In exchange, the fishermen demanded among other things that Tepco and the government continue paying compensation for as long as the nuclear plant damages their business.

Tepco is running behind schedule on a project to build a huge underground ice wall at the site, another key measure to prevent groundwater from reaching the reactor building basements.

Tepco Dumps Radioactive Water in Ocean To SAVE Ocean

Tepco Dumps 10,000 Bq Per Liter Tritium Ocean Release Ice wall 2015 https://youtu.be/0fP6iV0_47s
TEPCO releases statement saying they will pump up highly contaminated groundwater for release into the sea. Tepco will constantly check measurements while releasing minimally treated radioactive water into the ocean. The WHO standard says 10,000 BQ of “Tritium” Per Liter is OK. Tritium cannot be filtered or distilled. Half life like 12.5 years could be around 300 years to go back to barely detectable levels. It’s doubtful the Ice wall will ever create a seal to contain radioactivity.

Not to mention the tanks are not seismicly qualified and are only expected to last a short time. Many have already been leaking. They are running out of physical space to install more and more tanks.

* ECRR-MODEL VS. ICRP *
The existentiality of the lawfuly acceptable amount of radionuclides in the environment is the core question for all life on Earth. This question is scientifically formulated as the intelectual battle between two scientific models on the risk of the radioactivity, the acceptable levels of radionuclides in the environment. The presently by the governments used ICRP-model, by the experts of this website is found guilty to be the cause of ongoing genetical annihilation of all life forms as it underestimates the risks thousands of times. The ECRR-model is suggested to be used.

The recently resigned Scientific Secretary of the ICRP, Dr Jack Valentin , concedes to Pr. Chris Busby (ECRR) that the ICRP model can not be used to predict the health effects of exposures and that for certain internal exposures it is insecure by up to two orders of magnitude.
He also says that as he was no longer employed by ICRP he could agree that the ICRP and the United Nations committee on radiation protection (UNSCEAR) had been wrong in not examining the evidence from the Chernobyl accident and other evidence which shows large errors in the ICRP risk model.

Agreement reached on decontaminated water disposal

Fishers in Japan’s northeastern prefecture of Fukushima have formally allowed the release of decontaminated groundwater from around buildings of nuclear reactors into the sea.

The release is aimed at reducing production of heavily contaminated water in the basements of the buildings at the Fukushima Daiichi plant.

Groundwater flowing into the buildings is producing 300 tons of highly radioactive water daily, resulting in a huge number of storage tanks at the plant.

Plant operator Tokyo Electric Power Company, or TEPCO, and the government have been asking the fishers to allow the release to keep the water from flowing into the buildings and becoming heavily tainted.

TEPCO plans to use 41 wells already dug around the buildings to pump up the water and lower the levels of radioactive substances to between one-one-thousandth and one-ten-thousandth of their original amounts before releasing it.

The operator, the government and an independent institution plan to check so that only water below allowed levels is discharged.

On Tuesday, the local federation of fisheries cooperatives approved the plan on condition that the release rules are strictly followed and that compensation is paid for any damage due to harmful rumors.

Federation chairman Tetsu Nozaki said the approval was decided unanimously, but that some members were dissatisfied. He added that the plan is needed for steadily decommissioning the plant, and that he wants TEPCO and the government to keep their word.

The firm’s Fukushima headquarters chief Yoshiyuki Ishizaki said the plan is a big step forward in the decommissioning process as well as tackling the problem of contaminated water. He said fishermen told him that the plan could lead to rebuilding of Fukushima’s fishing industry, and that he will keep their remarks in mind.

TEPCO plans to start releasing the water soon.

Fishermen OK TEPCO’s plan to dump Fukushima plant water into sea

FUKUSHIMA, Japan (Kyodo) — Fishermen in Fukushima Prefecture approved on Tuesday a plan by Tokyo Electric Power Co. to pump up contaminated groundwater continuously flowing into the stricken Fukushima Daiichi nuclear station and dump it into the ocean after removing almost all radioactive materials from it.

The plan is one of TEPCO’s key measures aimed at curbing the amount of toxic water buildup at the complex. Local fishermen had long opposed the plan amid concern over pollution of the ocean and marine products.

“I don’t know if it’s acceptable for all fishery operators, but stable work of decommissioning (of the Fukushima plant) is necessary for the revival of Fukushima’s fishery industry,” Tetsu Nozaki, chairman of the Fukushima Prefectural Federation of Fisheries Co-operative Associations, told reporters after a board meeting.

He also called on TEPCO to make sure it will only discharge water which does not contain radioactive materials exceeding the legally allowable limit.

The amount of toxic water is piling up every day, as untainted groundwater is seeping into the reactor buildings and mixing with radioactive water generated in the process of cooling the reactors that suffered meltdowns in the nuclear crisis triggered by a massive earthquake and tsunami in 2011.

By pumping up water through drainage wells and dumping it into the ocean after treatment, TEPCO said it will be able to halve some 300 tons of contaminated water being generated each day.

In exchange for approving the plan, the Fukushima fisherman’s association demanded on Aug. 11 that the government and TEPCO continue paying compensation for the fishermen as long as the nuclear plant causes damage to their business, among other requirements.

On Tuesday, the National Federation of Fisheries Cooperative Associations also gave the green light for the release of treated water into the sea.

TEPCO has been struggling to resolve the problem of toxic water buildup at the plant for more than four years after the nuclear crisis, with radiation leakages into the environment still occurring regularly at the complex.

The company is also behind schedule on a project to build a huge underground ice wall, another key measure to prevent radioactive water from further increasing at the site.

Fishermen OK Tepco’s plan to dump Fukushima plant water into sea

FUKUSHIMA – Fishermen in Fukushima Prefecture on Tuesday approved a plan by Tokyo Electric Power Co. to take contaminated groundwater continuously flowing into the stricken Fukushima No. 1 nuclear plant and dump it into the ocean after removing almost all radioactive materials from it.

The plan is one of Tepco’s key measures aimed at curbing the amount of toxic water buildup at the complex. Local fishermen had long opposed the plan amid concern it would pollute the ocean and contaminate marine life.

“I don’t know if it’s acceptable for all fishery operators, but stable work of decommissioning (of the Fukushima plant) is necessary for the revival of Fukushima’s fishery industry,” Tetsu Nozaki, chairman of the Fukushima Prefectural Federation of Fisheries Co-operative Associations, told reporters after a board meeting.

He also called on Tepco to ensure it will only discharge water which does not contain radioactive materials exceeding the legally allowed limit.

The amount of toxic water is piling up every day. Tainted groundwater is seeping into the reactor buildings and mixing with radioactive water generated through cooling the reactors that suffered meltdowns following the March 2011 earthquake and tsunami.

By pumping up water through drainage wells and dumping it into the ocean after treatment, Tepco said it will be able to halve some 300 tons of contaminated water being generated each day.
