I'd suggest you go to the english version of tokyo denryoku..they give a daily update...also I understand the japanese minister of health has increased the max load of radatiation that one can be exposed to? and using helicopters, what a waste of time..they should position a fire engine pump truck. and pump seawater in to the reactor's cooling chamber.. fire engine pumps have high capacity pumping availabilty, which they can use untile the new power source is connected...
