Which of the 6 reactor cores at the Fukushima I nuclear power plant pose the most serious risks?

Do we depend on robots if the situation gets worse?

I would wager if suitable robots were available, they would already be on site.

Wow there are eight questions here, panicked much?
The tsunami was and will remain the most damaging part of this disaster.

@jaytkay – What about robots from other countries?

The tsunami was and will remain the most damaging part of this disaster.

What?

The dire situation of the tsunami victims does nothing to lessen the dire situation at the nuclear plant.

They are huge simultaneous disasters.

What about robots from other countries?

Japanese, foreign, whatever…I think if suitable robots were available they would be on site. Whoever makes such robots has few opportunities to use them. Why miss this one?

I agree @jaytkay – cities can be rebuilt after a tsunami. Long-term contamination of land is entirely different.

Here come the robots! And they are stupendously underwhelming.

Thanks @jaytkay for the link. It seems more robots will soon be on the way:

“According to the German media reports Japan has asked Germany for remote controlled robots for operations at Fukushima 1.”
