Nuclear waste management is a partly externalized cost (nuclear waste will outlive the companies that produced them). Sometimes decomissioning is externalized (e.g. https://en.wikipedia.org/wiki/THTR-300#Decommissioning https://en.wikipedia.org/wiki/THTR-300#Decommissioning). The effects of Uranium mining are externalized (e.g. https://en.wikipedia.org/wiki/Wismut_(mining_company)#History https://en.wikipedia.org/wiki/Wismut_(mining_company)#Histor...). The effects of Chernobyl and Fukushima were externalized. E.g. many boars are still too radioactive for human consumption in Germany.
