>>2442203A battery stores energy uranium IS the energy, not something like a lithium ion battery which only releases a small fraction of the energy stored, no one charges uranium
enrichment is the same as refining crude oil into gasoline or processing raw ore to make metal
Again, you get 75 units of energy back for every 1 unit you put, including enrichment.
Technically, by this argument, solars are batteries because it takes energy to mine quartz, purify the silicon and make the panel.
We can also bypass the enrichment process all together via advanced fast breeders (or breeders in general) or something like heavy water reactors like CANDU
