Seawater contamination does not decrease even with the impervious wall

From late July to early August, Tepco built the impervious wall on the coastal line of the seaside of reactor2.

They even paid the cost for pumping up the increasing groundwater due to the wall, but the seawater contamination does not decrease according to Tepco themselves.

Tepco measures only three nuclides, Tritium, Cs-137 and all β near the surface of the sea and the the lower part of the sea in front of the impervious wall.

It has been nearly 3 weeks since they completed the wall but no decreasing trend can be found.

You can ignore the truth but the truth won’t ignore you.

La contamination de l’eau de mer ne diminue pas même avec le mur étanche

 

Tepco a construit un mur étanche le long du rivage en regard du réacteur 2 entre fin juillet et début août.

Ils doivent même payer le coût du pompage des eaux souterraines qui montent à cause du mur mais selon Tepco eux-mêmes, la contamination de l’eau de mer ne diminue pas.
Tepco ne contrôle que trois nucléides, le tritium, le césium 137 et le total en β près de la surface de la mer et sur la partie basse de la mer en face du mur étanche.
Ils ont terminé ce mur il y a pratiquement 3 semaines mais aucune tendance à la diminution ne peut être remarquée.

Vous pouvez ignorer la vérité mais la vérité ne vous ignorera pas.

  1. No decrease. No rocket scientist needed..the U shaped canal, looking like a stream, the leaking tanks, cracks in earth, under ground RIVER flowing thru, and just gravel floors under the reactors(the tunnel floors)..no wonder no decease. Its leaking like a sieve everywhere, deep and shallow. The U shaped..”ditch”..heck the engineers just let the waste water flow…into the ocean..thats a significant ‘canal’..and shows lots of liquid waste cut into the banks. Its more of a natural stream than anything engineered, if it even was.

  2. No decrease:

    This is the TEPCO method of saying that the radioactive contamination levels continue to INCREASE.

    This is however, an expected, but hopefully transient outcome, even if the dam is intact and wrapped arround both above and below the FDNPP site. It is a result of the elevated ground water levels and thus pressures on BOTH sides of the lower dam. The flow rate will continue, but should soon cease to INCREASE in water flow rate. Similarly, the increasingly contaminated water, below the dam will likely continue to increase oceanic radionuclide contamination levels. This trend should also (hopefully) decrease over time. The PEAK concentration level may not be reached for several months, even if the underground dam solution is ultimately a success.

    This is WHY, responsible engineers, such as Arnie Gunderson, called for the underground dams, over two years ago. There is a significant turn arround time in such matters. TEPCO is ‘behind the 8 ball’ and will stay there for some time. Pumping some ground water out, will SIGNIFICANTLY speed the process, and should therefore continue.

  3. I went looking for an alternative to Bill Duff’s suggestion of storing tritium in a sunken boat in the harbour.

    Turns out that maybe mussels, as in bivalves, really like tritium.
    Many filter feeding marine animals hyperaccumulate heavy metals.
    They build tougher and bigger shells with it.
    Great Lakes in the US bivalves filter feed the whole volume of water every 5 days. They’re pretty efficient…

    The local Fukushima aquaculture industry, that’s struggling to keep going, could be contracted to bring Oyster and Mussel beds into the harbour, to filter feed the radioactive water coming into the bay.
    Heavy metals deposited into the shells are locked away.
    Freshwater mussels can biofilter on site.
    Bivalves in the bay that have already endured 2 years of radiation are a good nursery stock. Don’t CONCRETE OVER the seawall. It has the marine life with the best chance of doing the filtration job for you…..

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
