Sigh… Please find some reputable sources…
Anyhow, since there are NO experts in this particular incident because this is the FIRST time an accident of this type has happened, I would call the technicians and engineers who have been dealing first hand with this since the earthquake as the experts.
No one has removed a damaged reactor core from a damaged cooling pool in a crumbling building before. I have to have some confidence in the techs and engineers on the ground there doing the work day in and day out to complete this successfully because I do not think that there are other people out there with better expertise.
Is this entire operation extremely risky?? Of course. There are lots of things that could go wrong. In my work, we say that nothing is ever easy. The hard stuff is hard to do. Period. But the risk of leaving it there and doing nothing is worse.
And you're sure of this because?
Actually, the community of experts in nuclear power think TEPCO a buncha' bunglers. "Keystone Cops" one called them.
