Washington's blog has a good summary and a video clip that includes an interview with a nuclear authority who describes the disaster pessimistically, the "reactors are almost in the same situation they were in the early days of the accident"
Also NHK is reporting a cut to the power for units 3 and 4
NHK External power supply cut at 2 Fukushima reactors (hat tip ENEWs)
Tokyo Electric Power Company says part of the external power supply has been cut at the Fukushima Daiichi nuclear plant due to a problem in the transmission lines.
TEPCO said on Friday that a current breaker was tripped by a sudden surge in the external power lines, cutting off electricity to the No. 3 and 4 reactors.
The operator was forced to suspend a system treating radioactive water. Another system cooling the No.3 reactor's spent fuel storage pool was also shut down.
TEPCO says the pool's temperature remains stable at around 30 degrees Celsius.
After the power outage, a building serving as the headquarters for the plant's stabilization switched to an emergency generator.
TEPCO said work to inject water and nitrogen into the reactors has not been affected, as electricity is being supplied from other power sources.
MAJIA HERE: It is 12:34 am 7/22 (i need to go to bed). I cannot imagine how they are going to keep everything under control without electricity to spew water and chemicals on those blazing reactor cores and to circulate/add water continuously in unit 4's pool...
