Has the possibility of retrieving material from the elephants foot been considered ? Could a robot with a core-drill extract material, replace it with graphite, and place the cores in lead containers for transport to a reprocessing facility ?
Worth a lot less than the cost to recover it.A wasted resource.
Byproduct of civilization. Humans make those here and there. That one's just a few acres.A no-go area for a thousand years ?
We have to consider such effects when mounting electronics in the nuke plant.Everything should work for a few minutes, space-grade electronics should survive hours to days, and the most radiation tolerant components at particle accelerators can work there for months to years.
Radioactive slurry, potential electrocution hazards, or handling of a metal case filled with microscopic active particles? It seems to me any human involved with this operation would fare much worse than any equipment.in terms of drilling a hole into a cooled down reactor fuel that has combined with sand and reinforced concrete I think the drill bit would be the one that suffers the most
As I recall I've seen something about the slowly deteriorating surface of the stuff. If needed I might try to find a source.I've heard no reports that it's unstable, and if not unstable then it's best left alone .
Only fine electronics is affected, drills are not. The most problematic part is to keep an eye on the operation - even rad hardened cameras has a limited lifetime in such environment.Also you can't simply drill into it because Radiation levels that high degrade electronics so the drill would likely break down and die.
Drilling makes lots of radioactive chips and dust that have to be caught and handled. High potential for making a real mess.As I recall I've seen something about the slowly deteriorating surface of the stuff.
Yes, i figured you were correcting possible misconception that big industrial drills are sensitive electronic devices. It needed to be pointed out.I've just added my part in general.
