France is the one country that still has a nuclear arsenal but has to recycle its military grade fissile fuel, as it has dismantled the Marcoule installations producing military grade Pu 239, and the Pierrelatte military U 235 enrichment plant. https://fr.m.wikipedia.org/wiki/Usine_d%27enrichissement_militaire_de_Pierrelatte
(The last military grade generating reactor shut down in 2009).
Tritium is still being produced (given its short half life in the range of a decade), nowadays from a Civilian reactor.
