Contaminated Water Treatment at #Fukushima I: What Kurion Took Away, AREVA Put It Back

Radioactive cesium, that is.

TEPCO announced the numbers for the density of radioactive materials after the decontamination using Kurion and then AREVA.

940,000 Bq/cm3 --> Kurion, ND --> AREVA, 450,000 Bq/cm3, and 66,000 Bq/cm3 (2 tests)

1,100,000 Bq/cm3 -->Kurion, ND --> AREVA, 520,000 Bq/cm3, and 77,000 Bq/cm3

So what is TEPCO's solution to the conundrum?

Stop using AREVA.

Does the company know why this happened?


Is the company interested in knowing?

just a rumor...

I don't know how to contact you, so I write here.

Please take a look at those 2 links:

It is about one of the arrests from the 9.11 protest. This couple was arrested for no reasons, and police backed it up with made up accusations.

@anon at 8:50PM, it's not a rumor but an old piece of news from April, where the water from SFP spilled. Don't scare me.

To me it looks like that Areva's mistake was just not to participate in the dango.

Dango practices are outright illegal and sovery unwelcome in France and Germany and companies do not want to lose their reputation due corruption coming to the light.

I hope Areva will do some examinations by itself to see what really happened. I suspect some operating error or even manipulation on behalf of Tepco.

I hope this will result in one more hefty face loss for Tepco, demonstrating its incompetency.

After all, I suppose that these things will result in less willingness to help Tepco to get out of its maladies.
Nobody likes to help and then get defamed for "poor performance" as soon as Japanese companies come up with own products.
Nobody wants this sort of "technology transfer".

I just had to think of the fact that after the earthquake the US Army immediately offered helping out with its logistic capabilities to deliver cooling water to Fukushima and how this generous offer was turned down, even at the cost of having to use seawater.

It is so sad how Japan makes others unwilling to help and prefers to destroy itself because of idiotic "pride".

I think you are reading the data wrong. I think these are two separate treatment lines. The Areva treated water was sampled at 6:50am of the 15th. The Kurion treated water was sampled at 3:00pm on the 15th. If it is the same treatment line, then the Areva-cleaned water was then passed on to Kurion, where it was finally cleaned and nothing was detected.

I don't beleive the data. Areva's system was slower to process water. My suspicions are that Tepco wants to expediate the water processing by cutting out the Areva system. Why are the Ministries not sampling independently. Can a company with this history of collusion be trusted to self report?

Remember this article about AREVA's water system:

Thank you very much for linking to that article with excellent info about the Areva process.

However, I am not sure if France is the only "bad guy".

British Sellafield also has such a release pipe and the effluents are apparently less "clean", as beaches there already have been protected from public access with fences because of hazardous radiation contamination.

The Irish sea is extremely high radioactively contaminated, and it is unclear if the Sellafield reprocessing plant even uses water decontamination like La Hague.

Norway and Ireland are regularly protesting against the Sellafield releases that contaminate their coastline.
