Serious deterioration found in adsorption tower of multiple nuclide removing system ALPS

Following up this article..Multiple nuclide removing system ALPS had leakage due to “corrosion” / Only 2 months after test operation started [URL]

 

While ALPS is suspended, Tepco inspected the inside of the adsorption tower (6A). In the inspection, Tepco found the access door and the part around the welding line severely deteriorated. The color is changed to be rusty red.

The reason is not verified yet.

Truth is not truth because everyone believes in it. It’s the truth because it’s consistent and can’t be rebutted.

Alors que ALPS est suspendu, Tepco a inspecté l’intérieur de la tour d’absorption (6A). Au cours de cette inspection, Tepco a découvert que la porte d’accès et la partie autour de la ligne de soudure sont gravement détériorées. La couleur en a changé pour du rouge de rouille.

La raison n’est pas encore établie.

Ce n’est pas la vérité parce que tout le monde y croit. C’est la vérité parce que c’est cohérent et irréfutable.

  1. The nanotech for the adsoption system is derived from the way molluscs filter and capture metals in seawater.

    Are there shellfish on the sea wall at Fukushima?
    Can one of the cameras in the area zoom in on the seawall and pick up the detail of what molluscs, mussels, limpets, are attached to the rocks?
    The only upside of the leaking into the sea is that the seawall molluscs are now a petri dish of animals that can survive filter feeding from the radioactive water at the plant.

    Molluscs filter feed huge volumes of water, and the heavy metals they capture are deposited into their shells.
    The local shell fish industry, mussels, oyster bed farmers, have tanks specialised for their industry.
    These could be brought to the nuclear power plant site, and the trench water, local seawater, put through the shellfish, so they can filter it.
    As long as there is mesh over the tanks, so that insects and birds cannot get to the shellfish meat, then the deposition process can stay out of the food chain.
    Shells can be just deposited on site, the radioactive content is trapped in an inert substrate and will become a deposit layer in the site sediment.

    1. Helen, what a terrible way to look at animals – use them as filters for radioactive waste. Makes me sad 🙁

  2. http://en.wikipedia.org/wiki/Bivalvia

    A study of nine different bivalves with widespread distributions in tropical marine waters concluded that the mussel, Trichomya hirsuta, most nearly reflected in its tissues the level of heavy metals (Pb, Cd, Cu, Zn, Co, Ni, and Ag) in its environment. In this species there was a linear relationship between the sedimentary levels and the tissue concentration of all the metals except zinc.[92] In the Persian Gulf, the Atlantic pearl-oyster (Pinctada radiata) is considered to be a useful bioindicator of heavy metals.[93]

    Crushed shells, available as a by-product of the seafood canning industry, can be used to remove pollutants from water. It has been found that, as long as the water is maintained at an alkaline pH, crushed shells will remove cadmium, lead and other heavy metals from contaminated waters by swapping the calcium in their constituent aragonite for the heavy metal, and retaining these pollutants in a solid form.[94] The rock oyster (Saccostrea cucullata) has been shown to reduce the levels of copper and cadmium in contaminated waters in the Persian Gulf. The live animals acted as biofilters, selectively removing these metals, and the dead shells also had the ability to reduce their concentration.[95]

  4. Ha, ha, automatically I have been ‘identified’ online.
    There’s me cooking cupcakes with solar energy in the backyard.
    Anyone from the global nuclear and security industry who would like to drop in and discuss solar cooking with a pyrex bowl over some black glass marbles, with a baking tray of fresh steaming chocolate cupcakes is welcome to drop in…. The coffee is pretty good.
    My security clearance is sunlight grade.
    We can have a big old chat about how Wikileaks started in my loungeroom.
    Go outside guys, get some vitamin D into you this lunchtime, you’re going to need it.

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.
