Contaminated water crisis

21 tanks and 1km of pipe must be decontaminated due to the system failure of ALPS / Not known when to reboot ALPS

Following up this article.. [ALPS shut-down] Tepco has already transferred 2,500 t of unpurified water to 21 clean tanks [URL]

 

21 tanks and 1km long pipes need to be entirely decontaminated due to the system failure of multiple nuclide system ALPS (Advanced Liquid Processing System).

 

ALPS is one of the two major countermeasures for contaminated water along with frozen water wall. Tepco plans to process 1,960 tonnes of contaminated water by ALPS on the daily basis, but it hasn’t been in the full operation only to process less than half of the planned volume.

Before they noticed the system didn’t purify the water, they had already transferred the unpurified water to 21 of 1,000t tanks. Tepco is still planning to use these tanks to stocked clean water after ALPS processing, so they need to decontaminate the tanks and 1km long pipe.

 

They still don’t know when they complete the decontamination, but ALPS will be suspended until they complete.

Downplay it in the beginning, and quietly add more information so nobody notices it. All for not letting the cattle escape. This is their strategy.

21 citernes et 1 km de tuyauterie doivent être entièrement décontaminés à cause de la panne du système de filtration multi-nucléides ALPS (Advanced Liquid Processing System).

ALPS est, avec le mur souterrain congelé, l’une des deux principales solutions adoptées contre les eaux extrêmement radioactives. Tepco prévoit de traiter quotidiennement 1 960 tonnes d’eau extrêmement radioactive avec ALPS mais ça n’a jamais pu fonctionner plus que sur moins de la moitié du volume prévu.
Ils avaient déjà transvasé les eaux brutes de 21 des 1 000t citernes avant de se rendre compte que le système ne filtrait pas l’eau. Tepco prévoit toujours d’utiliser ces citernes pour stocker les eaux filtrées après leur passage dans ALPS, ils doivent donc maintenant décontaminer ces citernes et le kilomètre de tuyaux à présent contaminés.
Ils ne savent pas encore quand ils auront fini cette decontamination mais ALPS restera à l’arrêt tant que ce ne sera pas fini.

Le minimiser au début et ajouter tranquillement de nouvelles information pour que personne ne le remarque. Tout pour que le troupeau ne s’échappe pas. C’est leur stratégie.

    1. Tritium has a short half-life and emits Beta (β) particles (electrons). Tritium (β) particles have MUCH LOWER energy levels (velocity) than (β) particles from Strontium 90. Tritium decay produces no dangerous daughter isotopes; only water and helium.

      It is a VERY good thing to filter-remove the most dangerous radionuclides from the Fukushima water. Tritiated water can be injected, with significant safety, into underground (salt-dome) storage reservoirs similar to the US Strategic Oil Reserve, or the California Natural Gas Storage System.

      Or the Tritiated Water can be relatively safely stored above ground in double walled Stainless Steel tanks. Or tritiated water can be relatively safely stored at sea, in multiwalled, stainless steel vessels, underwater or at the surface.

      By the time any leakage and/or corrosion develops, the tritium will have half-lifed away to water and helium.

      1. Sell the Tritium.

        OK, clearly not all of it, or even a little bit of it, but it should be able to buy some positive public relations.

        TEPCO tells us there is no practical separation technology on an industrial scale for tritium. The scale of the technology for tritium seperation should be about the last thing that concerns TEPCO.

        There is a commercial market for tritium, it powers glow in the dark items like watches. World demand is about 500 grams a year with a value of ~ $30,000/gram.

        There is also a military demand for tritium. Clearly this is a politically sensitive issue, but Japan has already made the tritium, there seems no reason not to have them separate it as well.

        Harvesting helium also seem like a no brainer, it is not easy to obtain, and it is used in many markets.

        There should be no issues for using any recovered helium for cooling in medical or scientific equipment.

  2. Not much value

    Commercial tritium has higher concentration levels and limited commercial (competitive-marketplace) value.

    This stuff is not likely to have any commercial value.

    Probably not sufficient helium production, for any commercial exploitation value. Might offset some costs …. maybe.

    Fukushima is a TOTAL, man-made disaster, from all possible viewpoints.

    Cheap, bogus TEPCO ‘Team Nuke’ bullshit was the root-cause of most of the disaster. Ongoing cheap bogus ‘Team Nuke’ bullshit has compounded the damages.

    Sincerely,

    Bill Duff

    1. Makes sense, thank you, Mr. Duff

      Abe is Prime Minister of Japan, The 2020 Olympics, Restarting Nuclear Power Stations, Positive Trade Balance, Everything Else, [….. and fukushima]

      As long as Abe can keep thoughts of Fukushima out of the minds of the People of Japan, nothing will change. It will just become worse, each day

      I like the ‘ Team Nuke ‘ label

      Now I want a ‘ TEPCO Team Nuke ‘ t-shirt with a giant red rubber stamp looking ‘Bullshit’ printed across 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.
