Nuclear analyst concerned over Fukushima 'ice wall'

Nuclear analyst John Large, July 9, 2014: The cores remain active for hundreds, if not thousands, of years, so there’s a commitment to keep either the ice wall technology in place or to replace it with an alternate technology by some future generation. […] Water is coming off the escarpment above the three reactors, it’s then percolating through the ground — there’s hydrostatic pressures pushing the water up toward the sea level — it’s then collecting the fission products and radioactive products from the melted-down cores and taken out to sea. […] What I think they should now have a plan to tackle the root cause… How do you control, manage and eventually remove the reactor cores? […] If the reactor cores remain in there, it’s going to be a constant leachate (water that percolates through a solid and leaches out some of the constituents) of radioactivity.
