On the 2nd of September, 2021, Tepco announced the exhaust filters attached to the contaminated water processing system were breached. The processing system is ALPS (Advanced Liquid Processing System). The operation is suspended until Tepco defines all the damaged parts of the filters and completes replacement.
Nine days earlier, the radiation monitor alarm sounded during the transferring process of the byproduct slurry from ALPS. After the inspections, Tepco confirmed the absorption filters of radioactive substances had at least 10 breaches. There are 25 filters in total.
The spokesman of Tepco commented ALPS is expected to restart soon and there is no significant effect on the contaminated water processing.
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.
