[Disorder ?] Radiation level spiked up to 35.23 Sv/h in suppression chamber of reactor2 as the indicated heat went up

A thermometer indicated the RPV temperature is rapidly increasing in reactor2. (cf, [Disorder ?] A thermometer of reactor2 RPV indicating the rapid increase of heat, it reached 152.1℃ on 12/30/2012 [Link])

According to Tepco’s plant parameter, CAMS radiation monitor of suppression chamber (B) indicated the spiking up of radiation level at 23:00 of 12/26/2012, and it has been in stably high level. At 23:00 of 12/26/2012, it jumped up from 16.89 Sv/h to 35.23 Sv/h.

[Panne ?] Le niveau de radioactivité monte jusqu’à 35,23 Sv/h dans la chambre de surpression du réacteur 2 pendant la montée en température

Un thermomètre indiquait que la température de la RPV2 (Enceinte de confinement primaire du réacteur 2) montait rapidement. (cf. [Panne ?] Un thermomètre de la RPV2 indique une montée rapide, il a atteint 152,1℃ le 30 décembre 2012 [Lien])

Selon les paramètres usine de Tepco du 26 décembre 2012 à 23:00, le moniteur de radioactivité CAMS de la chambre de surpression (B) indiquait une montée de la radioactivité et ça c’est stabilisé à un niveau supérieur à l’ancien. Le 26 décembre à 23:00,  on a sauté de 16,89 Sv/h à 35,23 Sv/h.

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.
