The core of reactor units 1 appears to have melted through both the reactor itself and the outer containment structure. This is also the likely situation for units 2 and 3 as well. A total meltdown is not a good scenario – and that is a huge understatement.I disagree. Assuming the above is true, and it probably is, that would be WONDERFUL news. In a water cooled reactor, the sort that is used everywhere ( except for Chernobyl and other reactors in the former USSR which used graphite)
Reactors are either water cooled or air cooled. Graphite is used as a moderator to slow the neutrons and increase fission - not as a coolant. Heavy water is used as a combined coolant and moderator in some reactors.
