Lets look at hazards after TSHTF

Yup I think its the spent fuel rods that are the greatest risk to us, if cooling is lost from the containment ponds there wont be anything to dissapate the heat from the rods and you get a meltdown scenario. But in the reactor chamber providing someone hit the SCRAM button driving the graphite rods into the reactor and thus stopping the reaction there should not be as much of a threat. But either way its a nasty issue we would have to watch after TSHTF.
