So in Unit 3 at the Fukashima reactor there is no longer a pool that can be filled with water, and the spent fuel rods must be lying in a broken
twisted tangle on top of the reactor. Because the chaos can seriously inhibit the flow of coolant around the reactor, the reactor has a much higher
probability of reaching the 641 C threshold for a meltdown.
Not only is the flow of water inhibited, but it has to remove a much larger quantity of heat now that 40 years of accumulated waste that itself
requires cooling is packed around the reactor.
Their “last resort” solution of burying the reactor complex in sand and cement won’t work, because if the 279 kg of plutonium in the Unit 3
reactor reaches criticality, it would take a veritable mountain of reinforced cement to contain the resulting blast.
The only think I can think of that might contain the situation is if they dig or excavate with explosives a U-shaped channel to the rear of the
reactor, close off the channel entrance, open a channel on the seaward side of the reactor, and pump large quantities of seawater into the channel to
try and break up the concentration by a ‘reverse tsunami’ flush that carries the reactor remains out to sea.
It’s dirty and will require a long cleanup process, but anything is better that a supercritical explosion that takes out the entire complex of six
reactors with their combined forty year inventory of accumulate nuclear waste, and possibly a very great deal more.
