Japan Is Exploring How To Get Away With Dumping 1.1 Million Tons Of Radioactive Water From Fukushima Into Pacific Ocean

They’re running out of space to store radioactive water.

South Korea has fired off a letter to the International Atomic Energy Agency (IAEA) to express concerns over a Japanese plan to release radioactive water into the ocean which has been collected since the 2011 nuclear disaster, according to NHK

An official of South Korea’s science ministry said on Thursday said that the letter expresses the country’s serious concerns about the environment impact of such a release. The official also said South Korea asked the international nuclear watchdog to play a more active role on the issue. –NHK

Tokyo Electric Power Company (TEPCO), which operates the plant, is storing over 1.12 million tons of radioactive water on site, which is slated to reach capacity in 2022. The contaminated water has been treated using a system known as ALPS (multi-nuclide removal system), which removes 62 types of radioactive elements – not including tritium, before being stored stored in massive tanks on the Fukushima Daiichi grounds. 

The plan to release diluted wastewater into the ocean is one of several measures being discussed by an expert panel as possible ways to deal with the problem. Adding storage tanks is another option – which would kick the can down the road. 

the Japanese government is pushing to have the water released into the sea. But based on an investigation of 890,000 tons of Fukushima Daiichi water that had undergone ALPS purification (950,000 tons total), TEPCO announced in September 2018 that 750,000 tons – more than 80% – still included radioactive material above emission standards. Fukushima-area fishers continue to oppose the release of Fukushima Daiichi water in the ocean on that basis, and the Japanese government has yet to proceed with the discharge. –Hankyoreh.kr

On Wednesday, the Japanese government announced that it had invited foreign diplomats to its Foreign Ministry in Tokyo for a briefing on the situation – the 103rd such meeting, yet the first one ever announced. 

“Since the start [of the briefings], we have continued to provide information to diplomats in Tokyo about conditions at the Fukushima Daiichi Nuclear Power Plant since the East Japan earthquake,” said the ministry.

FUKUSHIMA Update (IT’S ALL DEAD!)


We don’t hear much about Fukushima anymore, do we? There’s good reason for the media to ignore it. Join The Watchman Review as they look at the Fukushima nuclear disaster… then to now. The truth needs told, and it’s scarier than you can imagine.

Record Radiation Level Detected Inside Fukushima Reactor Meltdown

TOKYO — A record radiation level has been detected inside the No. 2 reactor at the damaged Fukushima Daiichi nuclear complex, with the estimated reading of up to 530 sieverts per hour, the plant operator said Thursday.

https://s14-eu5.ixquick.com/cgi-bin/serveimage?url=https%3A%2F%2Faskaboutfukushimanow.files.wordpress.com%2F2012%2F05%2Fwhat-radiation6.jpg%3Fw%3D620&sp=cf2a966422e152dbffbae5332865b707

The reading means a person could die from even brief exposure, highlighting the difficulties ahead as the government and Tokyo Electric Power Company Holdings Inc. grope their way toward dismantling all three reactors that melted down in the March 2011 nuclear disaster.

The plant operator also announced that based on an image analysis, a 1-square-meter hole has been found on a metal grating beneath the reactor pressure vessel, likely caused by melted nuclear fuel that fell through the vessel.

The new radiation level, described by some experts as “unimaginable,” far exceeds 73 sieverts per hour, the previously highest radiation reading monitored in the interior of the reactor.

An official of the National Institute of Radiological Sciences said medical professionals have never considered dealing with this level of radiation in their work.

According to TEPCO, the extremely high radiation level was detected inside the containment vessel, in the space around 2.3 meters away from the base of the reactor pressure vessel.

According to the institute, 4 sieverts of radiation exposure would kill one in two people.

Experts say 1,000 millisieverts, which equals 1 sievert, could lead to infertility, loss of hair and cataracts, while exposure to radiation doses above 100 millisieverts increases the risk of cancer.

The latest discovery spells difficulty in removing the fuel debris as part of decommissioning work at the plant. The government and TEPCO hope to locate the fuel and start removing it from a first reactor in 2021.

The debris is believed to have been created as nuclear fuel inside the reactor pressure vessel overheated and melted due to the loss of reactor cooling functions.

In the coming weeks, the plant operator plans to deploy a remote-controlled robot to check conditions inside the containment vessel, but the utility is likely to have to change its plan.

For one thing, it will have to reconsider the route the robot is to take to probe the interior because of the hole found on the grating.

Also, given the extraordinary level of radiation inside the containment vessel, the robot would only be able to operate for less than two hours before it is destroyed.

That is because the robot is designed to withstand exposure to a total of up to 1,000 sieverts of radiation. Based on the calculation of 73 sieverts per hour, the robot could have operated for more than 10 hours, but 530 sieverts per hour means the robot would be rendered inoperable in less than two hours.

The latest analysis follows TEPCO’s discovery Monday of a black mass deposited on the grating directly beneath the pressure vessel, possibly melted fuel after the unit suffered a meltdown along with two other reactors at the six-reactor plant.

Images captured using a camera attached to a telescopic arm on Monday also showed part of the grating has gone.

If the deposits are confirmed as fuel debris, it would be the first time the utility has found any at the three units that suffered meltdowns.

Following the world’s worst nuclear disaster since the 1986 Chernobyl catastrophe, the plant’s No. 1 to 3 reactors suffered fuel meltdowns.

Portions of the fuel in the reactors are believed to have accumulated at the bottom of the containment vessels. But the actual condition of the melted fuel remains unknown due to high radiation levels.
