10:00 AM Eastern update...

Radio reports are that one of the condensate or else one of the feed pumps at No. 3 plant was tested as operable before the smoke event caused temporary abandonment of the Fukushima Daiichi site...

Here is the latest JAIF status document, with no important changes; No. 5 and No. 6 are on external AC power.


As of noon local (Tokyo) time on the 23rd, No. 1 reactor was still seriously overheated with a feedwater nozzle temp of 345C and a lower pressure vessel head temperature of 350C. (These are about 655F.) Of course, we've already reported some of the high temps and this is old data just released from Noon on the 23rd; it's now roughly 11 PM or eleven hours later. However, with the increase in core injection having begun at 2:33 AM .. up to 18 cubic meters per hour.. this might well have stopped or else is not effective. Sure to have more on this later.

10:10 AM Eastern Wednesday 3/23
