Reactor1 temperature rised after nitrogen gas injection
Since 5/14/2013, Fukushima Diary has been reporting the unusual increase of temperature in reactor1.
(cf, Reactor1 reaching 49℃, increased by 3℃ within 24 hours [URL])
On 5/17/2013, Tepco reported the temperature increased just after they injected nitrogen gas into PCV.
(cf, Tepco to restart nitrogen gas injection into reactor1 [URL 2])
However last year, reactor1 temperature decreased when they injected nitrogen gas, which is the opposite reaction from now.
According to the minutes of mid/long term Fukushima measures meeting held on 10/22/2012, Tepco is aware of this strange connection between nitrogen gas injection and the temperature but doesn’t know how it affects.
(cf, Tepco reported they don’t know why nitrogen injection decreases the temperature of reactor1 [URL 3])

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.
