Tepco injected boric acid in the night of 2/6, and increased the water amount by 3m3.
According the NISA’s restriction, Tepco is not supposed to increase the amount of water by more than 1m3 because it increases the contaminated water in water purifying system.
This means Tepco needed to increase water despite of the risk to increase contaminated water.
However, Newspaper’s report contradict each other.
Tokyo newspaper reported Tepco increased the water amount from 3.8 tones to 6.8 tones. On the other hand, Sankei newspaper reported Tepco increased the water amount to 13.5 tones.
Sankei newspaper is known to be more pro-nuke side. If they downplayed the situation, Tepco may have injected more than 13.5 tones of water.
This time, Tepco injected 960Kg of boric acid, which is the biggest amount ever.
On 1/26, Tepco stopped spray type of water cooling for 6 hours. Tepco analyzes melted fuel remained on the board to support nuclear fuel, which is shaped like a netlike appearance, dropped on the bottom of the container vessel and made a mass during the time.
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.
