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])
