Your description sounds like it would spread lots of radioactive dust though. Which is bad for both the people on site and everybody downwind from the blasted t

  It will make some more fission products, not much compared what it did in its life. I can't believe it will make enough heat to damage the structure or disperse radioactivity directly. If the neutron flux means that people can't go near the structure to maintain it then in the very long term you have more risk that the roof leaks, water leaks out, other paths of leakage don't get closed. Really they should scrape up the corium (like they did at TMI) and put it through reprocessing like any other nuclear waste. The risk of a criticality accident doesn't make that any easier.
