2.) We "could" remove the first cold Layer of the Coria,
the outer Mantel, and wait again until the next Layer is ready to remove


How in the blue fuck do you propose this is to be done

Your dear leaders have NO CLUE where in the batshit the coriums are.

There is NO to limited, LIMITED, technology. Correction, ZERO technology that can last any resonable amount of time near the melted fuel. The dose rates coming off of them would be in the MILLIONS of REM/h.

If the technology was available, they would have been digging already for them. Guess what.. its not and they have NO CLUE what to do EVEN when they do find them.

Spent fuel from a nuclear reactor gives off dose rates around 2 to 3 million REM/h. You would die within an hour if you were in the vicinity of the fuelling machine or fuel duct.

NO robot and for the technical aspect, NO COMPUTER OR ELECTRONICS can take those dose rates. They would be scrap in minutes. They would simply stop working. The amount of energy coming off the corium is MASSIVE and it would fry electronics without effort. NOT TO MENTION it would weaken the steel/aluminum so fast, whatever robot that spends any significant time near the fuel would essentially break apart.

YOU SIR ARE LIVING IN A FANTASY LAND.

I know what i speak of. It is my job to know these things and i have no reason to BS you and toss out random facts.
