Lewis is clueless!
Lewis, there are so many inaccuracies in your story it is amazing. For example, you claim that the reaction has stopped and that only the short half-life radionuclides are now generating all the heat. That's not completely true, with the control rods in, the uranium will continue to fission, just not at the same rate. You also neglect to consider what could happen if the fuel rods melt and drip into a puddle at the bottom of the reactor. Is it possible for the blob to get big enough to start the chain reaction back up? I think so. This may already have happened.
