“Well tell me which it was and why. Obviously you’re clueless since you can’t answer.
Do you even know what natural metal is? It is pure uranium, whose natural u235 component has not been artificially increased by enrichment.”
Sigh ....
Uranium in its natural state is an oxide, not a metal.
So uranium is not a metal when in oxide form.I see. While the chemical properties are changed, uranium remains a metal.
But if you want to get technical, Chernobyl used uranium in oxide form, pellets. The Chicago pile used both the metal oxide and metal without oxide.
Finally, whether metal, oxide or no, unenriched uranium contains .7% u235. Rbmks were designed to run on non-enriched uranium.
So prattle on, please!
