福島原発 IAEAレポートより

下記、IAEAのレポートでは1号炉温度１４４℃、２号炉温度１００度℃、３号炉温度１０２℃と報告されています。 １００℃以下が冷温停止の条件ですので、もう一息ですね。また海水から真水への転換も順調のようです。

IAEA Briefing on Fukushima Nuclear Accident (26 March 2011, 14:30 UTC)

At Unit 1, the main change is the injection of freshwater to the Reactor Pressure Vessel (RPV). The temperature measured at the bottom of the RPV is stable at 144 °C. Pressure in the RPV, containment vessel and suppression pool have come back down after having increased from 22 to 24 March.　At Unit 2, the injection of freshwater to the RPV commenced at 01:00 on 26 March.The RPV temperature is stable at 100 °C at the bottom of the RPV. The pressure measured in the RPV and in the containment pressure vessel is stable at circa one atmosphere.

Freshwater is also being injected in the RPV of Unit 3. Temperature measurement at the feed-water nozzle of Unit 3's RPV is still judged to be unreliable, but at the bottom of the RPV it is stable at 102 °C. White "smoke" continues to be emitted as of 23:00 UTC on 25 March from Unit 3, as it does from Unit 4. Unit 3 shows a consistently low containment drywell pressure of circa 1 atmosphere.
