There are three major problems at Fukushima: (1) Three reactor cores are missing; (2) Radiated water has been leaking from the plant in mass quantities for 2.5 years; and (3) Eleven thousand spent nuclear fuel rods, perhaps the most dangerous things ever created by humans, are stored at the plant and need to be removed, 1,533 of those are in a very precarious and dangerous position. Each of these three could result in dramatic radiation events, unlike any radiation exposure humans have ever experienced. We’ll discuss them in order, saving the most dangerous for last.I knew that there had been multiple meltdowns, but I though that the core damage was contained.
Missing reactor cores: Since the accident at Fukushima on March 11, 2011, three reactor cores have gone missing. There was an unprecedented three reactor ‘melt-down.’ These melted cores, called corium lavas, are thought to have passed through the basements of reactor buildings 1, 2 and 3, and to be somewhere in the ground underneath.
Harvey Wasserman, who has been working on nuclear energy issues for over 40 years, tells us that during those four decades no one ever talked about the possibility of a multiple meltdown, but that is what occurred at Fukushima.
It is an unprecedented situation to not know where these cores are. TEPCO is pouring water where they think the cores are, but they are not sure. There are occasional steam eruptions coming from the grounds of the reactors, so the cores are thought to still be hot.
The concern is that the corium lavas will enter or may have already entered the aquifer below the plant. That would contaminate a much larger area with radioactive elements. Some suggest that it would require the area surrounding Tokyo, 40 million people, to be evacuated. Another concern is that if the corium lavas enter the aquifer, they could create a "super-heated pressurized steam reaction beneath a layer of caprock causing a major 'hydrovolcanic' explosion."
I did not realize that we had the f%$#ing China Syndrome times 3.
