It seems the radiation levels inside the partially-melted-down reactor cores at Fukushima are above 500 Sieverts/hr. At that level, it seems robots have a life expectancy of only about two hours.

As a result, it may be quite some time before the cleanup operations inside the damaged reactors can commence.

I believe the biggest problem is that any imaging system currently in use gets burned out by the radiation in less than two hours. Someone needs to invent a CCD that uses a ceramic chip.

What's curious is that somehow they managed to clean up the mess inside Three Mile Island thirty years ago via remote control. It seems the focus today is on autonomy, but perhaps machines which have all their electronics in a remote location are what is needed instead for this type of disaster.

Or is Three Mile Island somehow significantly different? Perhaps the crane systems inside the Fukushima reactor buildings are not still intact?

I don't think that anything inside the buildings works, aside from a few water pipes.

We just need to go back in technology about 30 years. AFAIK, old video cameras used some sort of a tube, similar to an old radio with tubes instead of transistors.
Other wise, it would seem lead impregnated glass or a fiber-optic input (similar to the old fashioned colonoscopies where the doctor's nose got progressively closer to the patient's backside) to the CCD chip should work.
What did the Hubble use to protect its imaging electronics from the radiation of outer space since launch in 1990?

Here's another article about how to dispose of the tritium-tainted water (after cesium, strontium, and other radioactive stuff is removed). There is realistically NO other rational choice besides ocean disposal. Evaporating just wastes energy and it will still rain out in the ocean. Dumping it on the ground does the same thing. Hmmm, maybe they can sell it to US fracking companies so they can deep well inject it "safely" just like all the other fracking fluids.
