diplomacy of that. from a purely technical standpoint, the reactors that we are operating which we had to inject sea water, the moment they made the decision to inject sea water, which by the way they had no choice about. the death sentence was assigned for those reactors. they will never operate again. that was units one, two and three. units four, five and six were not operating at the time. we ve been injecting sea water into the spent fuel pools, but that is not the reactor. the consequence of injecting sea water in spent fuel pools is dramatically lower than the consequences of injecting that into a hot reactor. from a technical standpoint, an argument could be made. michael friedlander, thanks for joining us. sure. three stories coming from three different angles and personal struggles. let us know which one you want to see on the cnn newsroom. you vote by texting us.
the blast injured four workers, crumbled concrete walls and is heightening fears of a nuclear meltdown. joining us again, edwin lyman. clear this up for us. are we heading towards a meltdown? when we say meltdown we start thinking chernobyl, we start thinking three mile. yes. i think that the events are definitely heading toward a meltdown. this is why the japanese authorities are trying to resort to measures like injecting sea water into the reactor to try to cool it down. th does seem to be like a last ditch measure. we do know that there has been a loss of cooling capacity to some extent for more than a day now, and that could have a very serious effect on the radioactive fuel and we do know that there has been some damage to the fuel because of the detection of certain radio isotopes outside of the plant.
