Multiple nuclide removing system ALPS stopped again 22 hours after test operation restarted

Receiving the order of Japanese Prime Minister Abe, Tepco stated they are going to complete treating all the contaminated water by the end of the term of 2014. They commented it is possible with the multiple nuclide removing system ALPS.


As Fukushima Diary has been reporting, the multiple nuclide system stopped only 2 months after the test operation started this Spring. They found several parts severely deteriorated.

At 0:04 of 9/27/2013, Tepco restarted the system (C line), but it stopped again at 22:37 of the same day. It was only 22 hours after the restart of test operation.

According to Tepco, the process to remove α nuclide had the problem to discharge the slurry. The cause is not verified yet.


Tepco places the system “ALPS” as the last hope with the frozen ground wall for the contaminated water problem, but they haven’t established the technology.

Le système de filtration multi-nucléide ALPS encore à l’arrêt après 22 heures de remise en marche de test


Tepco a affirmé qu’ils allaient achever le traitement de toutes les eaux extrêmement radioactives d’ici la fin de 2014 sur ordre du premier ministre du Japon, M. Abe. Ils ont déclaré que c’est possible avec le système ALPS de filtration multi-nucléides.

Comme l’a publié le Fukushima Diary, le système de filtration multi-nucléides a été arrêté 2 mois seulement après le début de ses tests de fonctionnement, au printemps dernier. Ils avaient découvert plusieurs éléments gravement détériores (cf. 4 autres endroits du système de filtration multi-nucléide ALPS découverts détériorés seulement 2 mois après les tests opératoires)

Le 27 septembre 2013 à 00:04, Tepco a redémarré le système (ligne C) mais il a été à nouveau arrêté à 22:37 ce même jour, soit 22 heures seulement après la reprise des opérations de test.

Selon Tepco, le processus de filtration des α-nucléides a rencontré un problème pour se purger de ses boues. La raison n’en est pas encore établie.
Tepco place le système “ALPS”, ainsi que le mur congelé souterrain comme derniers espoirs de régler le problème des eaux extrêmement radioactives mais leurs techniques ne sont même pas établies.

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.
