Day 31: New quake temporarily stops cooling of Fukushima Daiichi

World Nuclear News reports that the cooling was disabled for 50 minutes, probably to short to have caused any further problems. If power had been disabled for a longer time period they could have connected the fire truck pumps again or switched over to the portable emergency diesel generators that are on the site now. For days the current pumps where driven by the diesel generators before being switched to the grid. Still the incident shows that the situation is still quite fragile and I wonder how long it would take the to switch power source if the of site power is disabled for a longer time.

Listening to the NHK newscast right now, they report that external power is once again working and the pumps are running again!
