Here is what looks to be another meltdown of epic proportions. What you are looking at is Unit 4 to your right, with smoke billowing from the top, quickly followed by a full blown giant blaze.
If this is indeed another meltdown, a dreaded Fuel Pool ignition, we are in a HUGE amount of trouble. These kind of fires are not extinguishable. In fact, any attempt can increase the reaction, and the radiation comng from it. This would cause an unstoppable plume of Plutonium to enter the atmosphere and once gain spread across the Pacific's skies.
