They announced that they solved the problem by eliminating the suspended materials on 9/13/2012, but on 9/14/2012, they had the problem of decreasing water amount to inject again.
In reactor1, water injection decreased by 10% from 21:00 of 9/13 to 1:00 of 9/14/2012.
In reactor2, it decreased from 1:00 to 7:00 of 9/14/2012.
They are trying to increase the water amount.
Tepco is still assuming it is due to the substances which flowed into the buffer tank and got stuck in the flow rate adjustment valves in the downstream side, narrowing the water flowing channel as a result.
The false report that Tepco reported the problem was solved in is below. [Link]
Ils ont annoncé le 13 septembre qu’ils avaient réglé le problème en éliminant les particules en suspension mais le 14 septembre le problème de la chute de la quantité d’eau injectée survient encore.
Dans le réacteur 1, l’injection d’eau a diminué de 10 % de 21:00 le 13 sept. 2012 jusqu’à 01:00 le 14.
Dans le réacteur 2, ça a diminué de 01:00 à 07:00 le 14 septembre 2012.
Ils essayent d’augmenter la quantité d’eau.
Tepco continue d’affirmer que ce n’est qu’à cause des particules en suspension qui se sont accumulées dans le réservoir tampon et se sont collées dans les vannes de réglage du débit sortant, donc en diminuant le débit.

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.
