LOL, please show me an example of a "window where you can look at a reactor core". Show me a window protecting someone from thousands of rads/hr from an active reactor core. Please :) And no, the radiation seen in space exploration is not comparable to the levels at Fukushima. Not anywhere close. Have you ever actually seen an endoscope? Do you have any idea how complicated they are, how many optical elements they have and how precise the tolerances must be? Did your study of wikipedia reveal the extent of transmission loss in rad-hard optical materials after exposure to levels of radiation near those at Fukushima? Because the link I gave you does. Read that and tell me how long you expect your fiber optics to last down there. I'll give you a hint: not very long. Tell you what, just make a sketch of your "low-tech" endoscope that withstands hundreds of Sv/hr, deals with hundreds of degrees of internal heating, is waterproof of course, and is robust to extreme physical abuse. And then come up with a way to remotely maneuver it into place through hundreds of meters of industrial wreckage, without using a robot. Then get ready to be famous, for your brilliant low-tech solution will be lauded by the international team of scientists and engineers working on Fukushima who simply hadn't thought of it for over 6 years.
