Latest info is that the temperature has started to increase again. If it reaches 80 C, cold shutdown is officially over. This is because the gages have a 20 C error margin. At 100 C, no cold shutdown. It is currently 78 C and Tepco as usual has failed to report their latest failure. And the cold shutdown was nothing but a lie to begin with, since about 2/3 of the total cores in three reactors have left the RPV. So we are about to enter the hot stage of the middle of this crisis.
Oops. Actually some of those make shift tanks were not even welded. Held together with bolts. And many have already leaked.
